The Shack…

I picked up the book on my kindle a few days ago, and had to finish another book before I could start reading The Shack.  I started reading it today – and I’m half way done.  It is a pretty amazing book.

I wanted to take a quick second to address a concern that I’ve heard about this book in it’s representation of the trinity.  I don’t want to say too much, because I don’t want to spoil the book; but I’ll say enough that you’ll get some general ideas of what is going to happen, so if you haven’t read the book yet, and you plan to – don’t read ahead just yet.

 

I’ve heard some concerns that the representation of the Trinity in this book is “heretical”.  There is a point in the book where the author very clearly addresses his purpose in having God appear as he does: a large African American woman named Papa. 

Within the freedom of prose, in my opinion his depiction does no harm to the nature of God – in fact, up to this point in the book, I think it has a liberating effect in trying to pull free the shackles of peoples mind’s of what they think God to be.

While God envelopes Himself in the language of male in the bible, He is neither Male nor Female, although both genders derive their essence from Him (in some mysterious way).

I’m not suggesting that it is o.k. in a theologically sense to refer to God as a woman, I think there is a purpose in God choosing to be identified as a “He” in the writings of the Bible, but again, God does sometimes choose to reveal Himself in many ways, whether it’s a storm or a whirlwind a pillar of clouds or fire, a burning bush, or a dove or even something as unobtrusive as a small whisper in a person’s heart – why not a large African American woman?.

So far, this book seems to have an amazing story to tell when addressing the problem of human suffering – I can’t wait to see if it gets better!

So how can God be both Just and Justifier?

 

One could ask: “How can it be considered Justice to allow one man to pay the penalty for another man”. The answer to how God can be both Just and Justifier can be found in no one but the person of Jesus Christ.

To start with, even in our human society there is allowances for legal representation of one person on behalf of another. In the concept of an ambassador, one person is placed in a position of authority to represent another. An ambassador has the right to speak and act on behalf of the one He/She represents.

Decisions an ambassador make are legally binding on those they represent. For example, my wife and I have signed a Power of Attorney for our adoptions, those that hold a power of attorney for us have the legal authority to make decisions on our behalf, and we are legally bound to those decisions and can be held responsible for those decisions.

Adam, as the first man, came under a covenant with God to represent all of mankind. And as our representative, Adam broke that covenant, and we took on responsibility for his actions. While this alone is enough to make us guilty, we also take on direct guilt, in choosing to stand with Adam in his disobedience through our own disobedience.

Then comes Jesus in the picture, as the second representative of mankind (the second Adam); his atonement was the result of Him taking on the legal representation for us; Jesus making a decision to honor an agreement between He and God the Father – thus allowing us through His representation to take advantage of this redemption by associating and coming into agreement with his decision to honor His covenant with God.

It is through this representative model that our penal system (and moral law) allows for the redemptive nature of Jesus. Adam as our representatives made us guilty, Jesus as our representative makes us redeemed.

However, this isn’t the end of the story. A second portion of this whole discussion comes into place when you look at what the purpose of a penalty is for.

In our country of the United States, legal penalties come about through breaking the law; and paying those penalties are to bring about restitution to those we have transgressed against. In our case, we transgress against our neighbor, which is transgressing against the local authorities, to state authorities, to governmental authorities, which in our country comes up to the President of the United States. In saying this, when we break a law in our country, we are transgressing the rule of authority of the President of the United states.

No one acting on behalf of the President of the United States has the right to forgive that transgression, however, the President of the United States (as the one who was transgressed against) does have a right to “wipe the slate clean” (we see this quite frequently with the concept of a Presidential Pardon). And yet, even in this case, it can be said that it is ‘unjust’ for the President to wipe away a transgression without proper restitution being paid, and yet, even in this injustice, our penal system allows for this.

So if we take this concept even one step further, any law broken, or any over-arching moral or universal law that is broken, transgresses the ultimate law giver: The Creator, and He and He alone has the right to pardon transgressions against Himself. The right… but not the requirement, God would be just in condemning all those who have transgressed his law, and yet, His love allows Him to pardon those who have transgressed against him. However, His justice requires that those transgressions be paid for with restitution, and this is where love comes in.

While God has the authority to wipe our transgressions away, His own nature binding Him to justice would not allow Him to let transgressions go unpunished (unlike our nature as humans that will allow this in the case of a Presidential Pardon as referenced above). Because all transgressions are ultimately against Him, He is the only one that can ultimately pardon those transgressions, and yet, because of the nature of our transgressions, we have nothing to offer in restitution to pay for the gravity of our transgressions.

Therefore, God showed both perfect love and perfect justice in providing of Himself for the restitution and redemption for His creation. And still those who do not receive redemption by bringing themselves into a state of agreement in the representation of the second Adam will still receive perfect love and perfect justice.

Eternity in their Hearts…

In today’s milieu there is a popular idea going around in a movie called “Zeitgeist” (or Spirit of the Age) that works to try to discredit Christianity by claiming that the claims of Christianity are not unique throughout the world, that they are just some replayed propaganda created by humans to explain away the origins of mankind.

Well, surprisingly enough, there are stories spread throughout the whole world similar to those found in the bible, interestingly, sometimes even by tribes of people that have never had any contact with the Judeo-Christian teachers, sometimes tribes whose beliefs that are so similar to Judeo-Christian teachings and yet, pre-date Judeo-Christian writings. 

I have just finished reading a book all about these types of occurrences, the book is called “Eternity in their Hearts”.  The stories are all very similar:  A Sky-God who is the one true creator of all things, creates a people, gives them a set of rules, they disobey the rules and come under punishment, until after many life spans these tribes forget how to worship that one true God.  Some even talk about a lost book that contains the information on how to worship this one true God, and some have legends of a yet future revelation.  In Zeitgeist the author goes even one step further to discuss the “redeeming son” that is sacrificed for the world (although a critical scholar would find many fallacious twists the author puts on some of these instances to try and make them look more similar to Christianity than they really are, but that’s out of scope for this discussion).

And yet, even without some of the manipulation of historical artifacts like those presented in Zeitgeist, this same theme rings over and over in human history, the similarities of the Christian gospel in religious folklore around the world; but let me ask: does this mean that Christianity is just a made up story, or perhaps, does this mean that God has been pre-evangelizing the world in general revelation to prepare the way for the special revelation made through the Abrahamic-covenant (and eventually Jesus Christ)?  Don Richardson in his book, “Eternity in their Hearts”, makes a very strong and compelling argument for the later.

I’ve written many times enough about my beliefs and who Jesus is, and why.  I don’t believe in blind faith!  I believe in a well thought out and calculated decision.  I look at Jesus Christ, and find Lewis’ epitome of the trilemma to speak mountains to this conversation:  Jesus Christ was either a Liar, one that could be equated to a hellish devil, a lunatic equal to a man who claims to be a poached egg, or He was who He claimed to be – there is no room for this “great teacher who really wasn’t God”, and clearly, if you have read my blog before, you know that I am convinced of Jesus’ divine nature (I won’t go into the reasoning in this blog, but check back issues).

And speaking of C. S. Lewis, in his book Mere Christianity, he talks about what he terms “Good Dreams”.  Lewis states that all these stories that we find so similar to Christianity spread throughout the ages, shouldn’t bring us to a point of questioning the uniqueness of the gospel, rather it should bring us to a point of worship, in which we realize that all these stories are pointing to the one occurrence in the history of mankind where “He became flesh and dwelt among us”. 

You see, these stories outline and pre-evangelize (or provide redemptive folklore as Don Richardson calls it) to the world, pointing to the one point in space and time when God would actually bring to a culmination all the ideas and thoughts He has been spreading throughout time.  In this one time and historically verifiable individual, we find the final chapter written.

If you are at all interested in this (either because you find it a bunch of baloney, or because you are intrigued, and would like to be shown some serious evidence for these claims) – I HIGHLY recommend picking up and reading Eternity in their Hearts.  I had a hard time putting it down!

Now, I’m reading another Don Richardson book about Head Hunting Cannibals who pride themselves in seeking friendships with people, just to “fatten them up with friendship for the slaughter”.  Don went among these people to evangelize to them (omg!), and what he found…. well, you’ll just have to read it for yourself!  😉

Does God Really Exist?

Saturday, March 14, 2009 Jediah Logiodice

I spent some time revisiting this topic for a class discussion I was having with the young men in our Church – I figured I’d post it here too.

Does God Really Exist?

What if someone asks you “Why do you believe in God”, but they don’t believe in the bible? Trying to prove the God who is revealed in the bible using the bible is a form of “begging the question”. An example of “begging the question” is as follows. Question: How do you know God exists; answer: because the bible tells us so. Question: But how do you know the bible is right; Answer: because God says it is!

You see, in this type of reasoning, you try to prove that God is real by using the bible, and yet, you use the bible to prove God is real. The argument is circular, and literally “begs the question”.

Remember, the Word of God is alive and sharper than any two edged sword (Heb 4:12, NIV), however, you can’t expect people to understand the power of the bible, if they don’t believe in the existence of God in the first place. So, what other kind of reasons could you use without appealing to the scriptures to show that God exists?

As we discussed in our class, here are some available options (although, this list is not complete, and is not as detailed as it could be):

Argument from Experience:

While you can’t see the wind, you can see the things the wind does and experience the feelings caused by the wind (e.g. blown hair, sand in your eyes, etc.). One argument for the existence of God is based on the things that we can see or experience as a result of God. The argument could go something like this: I have experienced God, therefore I know God exists.

While this argument is very powerful for the individual who has experienced God, it falls short of being able to convince someone that has never experienced God (i.e. How could you explain color to someone who is color blind, they would really have to have faith in you and your experience of color in order to believe in color).

Another reason to be cautious with the argument is that sometimes our feelings might not always represent reality (e.g. feeling like someone is watching you, when someone really isn’t [or at least as far as you knowJ]).

Teleological Argument (Or argument from design):

Another argument for the existence of God is based on the complexity of human life. The argument can be similarly compared to an argument set forth by William Paley that states an idea that if someone were to come upon a watch while walking, they would not assume that the watch ‘just appeared’ or ‘came to exist by itself’; logic would seem to dictate that there was a watchmaker that made the watch.

While some will find this argument to be very compelling; at the same time, there is a danger in appealing to the idea of a “God of the gaps”, i.e. invoking God for anything that we can’t understand based on our current scientific knowledge. The problem is that the more we, as humans, can understand based on continued evaluation of the natural laws, the less room there is for “God”, if “God” is defined as The Being that does all the things that we can’t explain.

Ontological Argument (Or argument from being):

The ontological argument is an argument that has been around for a long, long time. I enjoy Anselm’s version the most, and therefore will use it. The Ontological argument is a form of philosophical reasoning that tries to set forth a statement where the conclusion is true, as long as each of the individual statements is true.

Anselm’s argument goes something like this:

1. The definition of God means “The greatest thing”

2. Things that are outside the mind (in reality) are greater than things that are only in the mind (imaginary).

3. If God is only in the mind, then there would be something greater than God, that is, a God that exists outside of the mind.

4. Because the definition of God means “The greatest thing”, by definition, God has to exist outside of the mind, because He must be greater than the God that exists in the mind.

5. Therefore: God exists outside of the mind.

Cosmological Argument:

When discussing existence, the idea will inevitably arise that asks: “Why is there something, rather than nothing”. This question is phrased in such a way to show that the asker is searching for a cause or reason of existence; however, the question itself presupposes the idea that there really is something rather than nothing (that things really exist).

We’ll assume that everyone reading this agrees that things do exist (otherwise, you’re not really reading this, so it doesn’t really matter). So the next question is “Where did this something come from?”

From all that is known of science and philosophy, there is a premise that says “if there was ever a time in the existence of the world that there was nothing, absolutely nothing, than today, there would still be absolutely nothing, for out of nothing, nothing comes!”

Let me put it another way: If there was nothing, and something needed to make itself out of this nothing, then this something would have to be made before it could be made, that is, it would have to pre-date itself to create itself. This premise is logically impossible. In fact, even God, if He exists, can’t make Himself.

In philosophy, when discussing the concepts of existence, there are two primary terms that are put forth to identity existence. In existence, there are things that are contingent (i.e. things that rely on something else to create them) or there are things that are necessary (i.e. something in which its very essence is complete and existing with neither beginning nor end having no need outside of its own self).

While there is so much detail that can included on this one topic; the summary is this: things exist, and yet, to exist, there must be a cause, however, if there is a cause, there must be, somewhere in the history of past causes a very first cause. That very first cause cannot be caused, and cannot cause itself, and therefore the first cause must by necessary (as defined above).

In the end, the cosmological argument, can be understand in a very simplistic form which states:

· The world exists

· There must be a reason that the world exists

· The reason must be provided by something that is necessary, not contingent

· Therefore: A necessary being exists, and God is that necessary being.

Argument from Universals:

This is an argument that is used to help underline the existence of a universal idea, most often the universal of a moral value. C.S. Lewis pointed out in his book Mere Christianity that while people will often argue about that fact that a “standard of morals” does not exist, the very fact that they are arguing goes to prove that they both believe there is a standard that they are appealing to. I would never try and convince you of “right” versus “wrong” unless I had some standard of right to point at.

This argument is sometimes put forth in a similar fashion as was done by St. Thomas Aquinas:

· Something can be judged more or less good only if it is held up to a standard of that which is perfect

· Things are judged more or less good

· Therefore: a perfect standard exists, and that standard is God

Pascal’s Wager:

In final, Pascal’s wager, which we really didn’t talk about in class, makes the argument that it is smarter and safer to believe in God than to not believe in God. While I don’t necessarily condone this type of reasoning (because it really doesn’t bring someone to a true faith in God), it certainly can be used as a means to get people thinking. Pascal’s wager goes something like this:

· If God doesn’t exist, but you believe in him, you will lose a little bit of time and money now, but nothing in eternity

· If God does exist, but you don’t believe in him, you will save a little bit of time and money now, but you will suffer for eternity

· Therefore: It’s a much wiser idea to believe in God.

This is why I have such a hard time with Math….

Do you think it’s possible to be too logical for math? Follow this thread below, and see my question and my professors response… It legitimately looks to me like you can’t figure out the order of operations in a word problem unless you know what you’re answer is supposed to look like… does that mean the rules of the order of operation doesn’t necessarily apply without some other external logical application?

 

I think this is why math frustrates me – I probably just over think everything. =(

 

My Original Question:

Content Author: Jed Logiodice

When determining BAC (page 34), the following word problem is given:

BAC = number of oz X % alcohol X 0.075 / body weight in lb – hr of drinking X 0.015.

To simplify the question let w = number of ounces, let x = % of alcohol, let y = body weight and let z = hours of drinking.

When the book gives the BAC equation of being:

w * x * .075 / y – z * .015

This can create an order of operation like this (w * x * .075 / y) – (z * .015) [which results in the answer the book is looking for], however, why could one not equally contrive the following equation out of the above word problem:

(w * x * .075)
___________
y – (z * .015)

The way the word problem is written, it appears equally valid to assume either order of operation – however, unless one assumes the first, the answer will not match what the book states it should.

Is there some rule of order of operations that I’m missing for word problems that says “Never use fractional notation, unless the question is asking for a fraction”?

Thanks!

 

My Professors Response:

(w * x * .075 divided by y) – (z * .015)
Note: I have added parentheses to show that we do ALL multiplication and division from left to right before any addition or subtraction.

w = 4 * 12 = 48 oz

(w * x * .075 divided by y) – (z * .015)
(48 * 3.2 * .075 divided by 190) – (2 * .015)
= (153.6 * .075 divided by 190) – (2 * .015)
= (11.52 divided by 190) – (2 * .015)
= (.060631578) – (2 * .015)

Remember, we do ALL multiplication and division from left to right before any addition or subtraction so our next step is to multiply 2 * .015

= (.060631578) – (2 * .015)
= (.060631578) – (.03)

= .030631578

Rounded to the nearest thousand (3 digits to the left of zero), we have .031 as our answer

 

My Follow up Question:

Author: Jed Logiodice

But when I read the statement I saw this:

(w * x * .075)
____________
y – (z * .015)

instead of this (w * x * 0.75 / y) – (z * 0.15).

i.e. how was one to know that it was intended to be a linear equation (where the rules of operations went across from left to right, instead of above and below the division line separately).

I really thought that (w * x * .075) was the dividend and (y – (z * .015)) was the divisor…

Does that make sense?

I know it might seem like a foolish question; but I literally spent like 20 minutes doing that question over and over and over and never getting the right answer (but always getting the same answer); until I accidentally figured out that it was just a single linear equation, and then I started to ask myself “How was I supposed to know that, other than just assuming, was there some clue I missed”?

My single biggest problem with math is that I way over-think things!

 

My Professors Follow up Response:

One should always assume that we should follow the order of operations unless brackets or parentheses or a fraction bar is in the formula. OK?

 

My Follow up Request:

 

Even in word problems?

Take for example this problem: If you take 6 eggs and divide them among 2 women and 1 man, how many eggs does each person have?

If we always keep the order of operations (without brackets in the sentence) then the answer is (6 / 2) + 1 = 4; 4 Eggs a piece is obviously the wrong answer in this case – although it meets the rule of the order of operations we’re describing.

However, it would seem more logical (and in this case correct) to do 6 / (2 + 1) = 2. This gives the right answer (which we can verify because we know what the value should be), but doesn’t follow our prescribed operational rule.

Taking this discussion back to the case of the BAC – the same logical argument could be applied to the word problem, causing one to interpret the problem with a numerator and a denominator as a fractional statement, rather than just a linear equation – but one wouldn’t necessarily know that the answer was wrong (and what real order of operation was intended), unless one knew what the answer was supposed to be…

So I’m still left wondering – how we can tell in a word problem like the BAC what the real order of operation is supposed to be – without knowing what the answer is supposed to be?

I apologize if this appears as sophistry… I’m legitimately trying to figure out why I had the wrong answer; when from my viewpoint the way I executed the problem was equally as accurate as the way the book did.

Perhaps I’m too logical for math? 🙁

My statement of Belief

I believe that the creation of the universe and life is the act of an intelligent creator; that contingent beings or creations cannot be created except that there be some non-contingent being whose very nature provides and requires aseity and eternality in its nature.

I believe that true science and true religion do not contradict each other rather they uphold and support each other, and as Sir William Bragg said that Science and Religion are opposed, only such as the forefinger and the thumb are opposed. That with Science and Religion together, you can grasp anything.

I believe that the state of the world today is not as it was intended to be; the wars, the hunger, the death, pain and dying. I believe it is the result of a disobedience to a given mandate provided by the creator of life and the universe.

I believe that our cultural mandate as human beings is to work to restore the original state of creation; by learning to love and provide for other people as we love and provide for our own.

I believe that our religious experiences should not be held separate from all other experiences in our world, and that a world view must remain consistent in all areas and portions of life and existence.

I believe in life after death, that mankind was created with value that extends beyond the dust of the earth and that our experiences, our trials and our undertakings here encourage, strengthen and prepare us for a future life that will unfold through the annals of history.

So what came before that?

 

This thought came from a “What caused the Big Bang” type of discussion.

 

Something had to cause the Big Bang, unless the Big Bang always existed (which is not possible, as it would have always existed as a point of singularity unless acted upon by an outside force – so then the question would be where did that force come from, and you would end up in a impossible series of circular questioning).

 

So, when discussing the Big Bang – something caused it – it is not possible to have something come from nothing (ex nihilo nihil fit) [Out of nothing, nothing comes].

 

In order for something to come from nothing, it would have to create itself. And something would have to predate itself before it could create itself. That is, it would have to exist, before it existed. This is a logical impossibility.

 

Nothing has ever come from nothing – philosophically and logically speaking, if there was ever a point in existence where nothing existed, then nothing would still exist – and because we do exist, we know there was never a time when nothing existed (Thomas Aquinas makes this argument in his Quinque Viae).

 

In fact, not even God could create himself; therefore God must have always existed (which is a central claim to the Judeo-Christian doctrine).

 

Additionally, God would be changeless (RE: The same, yesterday, today and tomorrow) – another foundational claim to central Judeo-Christian teaching, and God would need nothing, He would be complete and whole in his personage, being able to exist eternally without input or output (another central claim to the Judeo-Christian doctrine).

The Unnoticed War?

Wow! I’m watching Expelled: No Intelligence allowed right now. While I know that today biology speaks strongly against the undirected, random chance of evolution; most people do not.

Most people think of evolution as classical Darwinism (random and accidental), despite what science is now teaching about what appears to be design in creation. That’s typically because of the polarization that the secular and religious world views continue to propagate against each other – speaking at each other, instead of to each other.

However, above it all, understanding that the views of classical Darwinism is more than just a theoretical discussion – it is surprising to begin to understand how much classical Darwinism has really brought to our society: Nazism, Abortion, Eugenics and Euthanasia to name just a few.

I’ve never thought of the full implications of classical Darwinism – but now that I’ve been exposed to it – I can now see that for one to remain consistent with their world-views; if one was to fully embrace classical Darwinism, those other positions must necessarily follow.

Perhaps there is more of a war going on then we realize…

How do you define ‘life’

Has anyone ever thought about the irony of the way we use the word ‘life’?

For example, I’m studying Astronomy right now. Scientists state that the evidences show that there was life on earth at least 3.5 billion years ago. This life was in the form of microscopic organisms. This scientific evidence shows that life has been around on planet earth for at least 3.5 billion years (Bennett, Donahue, Schneider, & Voit, 2007, pp. 709, 710).

On the other hand you have people who still want to claim that the zygote in the womb of a living human does not constitute ‘life’.

Does there seem to be some inconsistencies here? I think so!

Introduction

 

One commonly held view of the creation of the universe states that “In the beginning, God created the heaven’s and the earth” (Gen 1:1 New International Version); another common view of the creation, while not contradictory, definitely less mystical goes a little something like this: “Bang!”.

Fast forward some 14 billion years, and zoom in billions of light years to this spiral galaxy called the Milky Way, into this cluster of planets within a solar system that surrounds a small, yellow dwarf sun, to a tiny little planet, that at first seems quite insignificant, and yet with a careful study of the universe it is found that creation has been tuned to bring about a species called humanity apparently for the very purpose of allowing humans to ask the most basic of fundamental questions like: “Where did we come from?”, “Why are we here?” and “Where are we going?”.

Terra Mater – Surviving on Planet earth

 

To begin our journey, we find that this planet maintains a very delicate harmony with aerated oxygen compounds, with nitrogen cycles, and with water cycles which provide a basic substance for life to flourish. These components all maintain coherence within an atmosphere that not only provides a base for these complex cycles, but also traps heat warming the surface and filtering out harmful radiation from bombarding the flora and fauna that has taken up residence.

On top of this atmospheric cocoon we find a magnetic shield also providing protection from harmful forms of radiation. We find a moon in harmonious dance, feeding into tidal waves that pull the oceans to and fro aerating the oceans and providing for a flourishing of oceanic life. And still, even further out, we have this star, called the sun that provides heat and warmth and the breath of life through photosynthetic planetary life. By whatever appropriate means you come to the final conclusion, it appears undeniable that the universe and everything within it was finely tuned to produce life. And thank goodness for that, or otherwise, I would not be here writing this paper, and you, in turn would not be reading it.

A further review of this tiny little planet would show that while most of these tiny little objects we call humans are busy scurrying around from day to day, unaware sometimes of how immaterial they really are, we also find that among these humans there are those that will pause, look up and think about what is out there, somewhere beyond the troposphere, beyond the stratosphere, the thermosphere, and even beyond the exosphere; far out in the dark night sky.

The story of this astronomical undertaking begins with such an individual; his name was Isaac Newton.

While there were many important names attributed to discoveries and classifications of astronomy long before Newton, like Johannes Kepler, who provided fundamental concepts around planetary motion, it was Isaac Newton who created three universal laws that explained motion on a grand scale. Newton’s laws were so fundamental to the understanding of the universe, that Newtonian Physics dominated the world of physics for a few hundred years, until the introduction of Quantum mechanics in the late 1800s.

 

Stellar Properties

 

While Newton’s version of Kepler’s third law of planetary motion was able to provide information about the mass of stars when found in a binary system, he had even more to offer within the world of astronomy than just the laws of motion, for it was Newton who first provided insights into the nature of light (Bennett, Donahue, Schneider, & Voit, 2007, p. 148).

Through advancements of the study of light (spectroscopy) that came later, scientists and astronomers found that through emission and absorption lines they could determine the chemical makeup of distant light producing objects (Bennett, Donahue, Schneider, & Voit, 2007, p. 162).

Additionally, by examining the spectrum provided by these objects in conjunction with observational laboratory studies of spectral lines of known chemicals, scientists could also determine if objects where moving towards our planet, or away from our planet, and could even determine how fast these objects were themselves rotating (Bennett, Donahue, Schneider, & Voit, 2007, p. 168). Another use for spectral lines was later found in categorizing the surface temperature of stars (Bennett, Donahue, Schneider, & Voit, 2007, pp. 508, 509).

Further investigations of stars provide detailed information about the stars luminosity and their apparent brightness. By measuring a stars visual brightness, and measuring a stars distance (e.g. through parallax) we can then determine how bright a star really is through the inverse square law.

And so, we find that Newton and his discoveries paved the way for understanding a stars luminosity, temperature, density, and chemical composition!

 

Stellar Life

 

As we look out into the night sky, we can tell, sometimes even with the naked eye, that not all stars are created equal. Based on a stars surface temperature, some stars produce reddish light, some stars produce white light, and some stars produce yellow light, and some stars may even produce blue light (Bennett, Donahue, Schneider, & Voit, 2007, p. 508). While some may be tempted to speculate that the more yellow and white stars are happier stars than the redder (angry) and bluer (sad) stars; for a star, brightness depends not on its cheery disposition, rather it depends on its most fundamental property at birth: mass.

From birth to death, a stars lifetime is strongly influenced by the mass it is first created with. The larger a star, the faster and hotter it burns, the heavier the elements it produces through its nuclear fusion process which are essential to life, and the more spectacular its final days of destruction will be.

While a massive star will end in a supernova that leaves behind a neutron star, smaller main sequence stars will most often outlast these stars by millions of years.

A main sequence star will begin by the compression of hydrogen and helium until the force of gravity heats the core enough to initiate nuclear fusion. The main sequence star will continue in this state through gravitational equilibrium for millions of years, which is the state that the sun is currently in.

Once the main sequence star has used up all of its hydrogen fuel, there is no longer enough outward pressure to keep the star from collapsing under the great gravitational weight. As the star begins to collapse inwardly, layers of hydrogen surrounding the collapsing core will heat up until the layers reach the point of nuclear fusion.

This will cause the star to expand becoming a red giant, which can, at its peak be “100 times larger in radius, and more than 1,000 times brighter in luminosity [than the sun] (Bennett, Donahue, Schneider, & Voit, 2007, p. 551).”

As the layers of hydrogen burn up, they will deposit helium into the shrinking core, which will continue to heat up. Once the helium core reaches 100 million Kelvin it will start nuclear fusion in the inner core as well.

Now that the star has both a helium nuclear active core and hydrogen nuclear active layers, eventually the star will undergo a helium flash, expanding the hydrogen layers, which will subsequently cool causing the star to produce less visible light.

Once the star has completely converted hydrogen to helium to carbon, nuclear fusion will cease, the star will cast off its outer layers in a brilliant show of lights called a planetary nebula, and all that will remain is a white dwarf. This white dwarf will continue to produce light until such time as it has cooled in the near distant future.

Both massive and not-so-massive stars have one thing in common: they create and recycle elements within the universe, and provide the building blocks that feed into the creation of existence of life on earth. They are a fundamental part of our circle of life.

 

Conclusion

 

In the end, we find that this massive beautiful universe as we can currently observe has played a significant role in the creation and maintenance of the very lives that we have been given. This very existence allows us to study and observe the universe, and should leave us within the fullness of wonder and awe.

However, without the capability to see beyond the stars and the universe as it exists, the scientific pursuit into origins ends at the moment of creation, and provides no further means to research these existential questions, and thus, within science alone, we are left in the state as if waking from “a bad dream (Jastrow, 1992, pp. 106,107).”

To build upon Einstein’s thoughts when he said: “the most incomprehensible thing about the universe is that it is comprehensible (BrainyQuote.com, 2008)”, I would leave you with the final question that remains unanswered and incomprehensible from a scientific perspective, and that question asks “why?”.
