What I'm about to present is not meant to, nor can it, debunk creationism. The fact that we can't even wrap our meager minds around the infinity of
time and space tells us that anything is possible.
Like most people on this small, life giving dust speck, I found myself looking into the sky at 4 years old, wondering where it ends. Somewhere along
this path to my current day being, I ended up on a collision course with the day that I just had to know. Although I don't yet, someday I might!
While growing up, I went to church, said my prayers, and still find myself confiding, within, to an entity that seems to have forgotten that I exist.
After losing so many friends, my girlfriend at 28, my sister, and nearly me a few times, I found myself rather God-less.
I realized that if I was ever to understand who, or what, I was, I'd have to learn everything I could about that which I could not see. Knowing that
faith is a gift I have yet to receive (Tom Hanks), I turned to physics for clues to the answer.
Doing the math, I learned that energy does, indeed, equal mass at rest times the velocity of light squared. The mere fact that mass can be converted
into energy, and vice versa, seemed so unreal to me that I was compelled to understand it better.
Now I was getting some answers, yet for every one explained, there were two more questions.
I learned about the Law of the Conservation of Energy, how it doesn't really go away, but merely gets transferred. I learned about quantum mechanics,
how electronics work, and also did the math showing that post Newtonian physics (Einstein's relativity) can't be applied to the very small.
I discovered everything I could about the tiny, and once I realized that it has taken man more than 30 years to go from 10-16 to 10-17 (really small)
that I'd looked inward deep enough, and that I could spend a lifetime between there and the minute-ness of space itself without much progress and a
whole lot of un-proven math. Satisfied with what I knew, I left it up to others, and looked outward for the bigger picture. I had strayed far enough
away from my original question.
It wasn't until I had studied astrophysics for a while, that I glanced back at the very small, and what I saw, for once, started making sense.
The current day understanding of our universe, is that it's 13.7 billion years old, and originated with a big bang. It's also been theorized that it
began with equal parts of matter and anti-matter. When a particle and its anti-particle meet, they annihilate and cancel eachother out, emitting
photons in the form of gamma rays. Through a hypothetical physical process called baryogenesis, an asymmetry between baryons and antibaryons left the
small amount of matter we see today. In other words, we're made up of the scraps.
So the universe, in the beginning, was very hot, very dense, and expanding rapidly. What used to be 10^30 degrees, is now a mere 2.7 Kelvin, barely
more than absolute zero.
The microwave radiation we see left over from the big bang, also used to be very short wave gamma rays.
At ten microseconds after the big bang, things had finally expanded, cooled, and calmed enough for protons (two up quarks and one down quark) and
neutrons (two down quarks and one up quark) to form.
By the time it was one second old, we were left with protons, neutrons, electrons and lots of radiation.
Fast forward almost 14 billion years...
As recent as the early 1920's, the general view of the cosmos, was that it consisted entirely of the Milky Way Galaxy. That's when Edwin Hubble got
his chance to observe the sky with the world's largest telescope, the Hooker 100 inch, at Mt. Wilson, Ca., which I grew up lucky enough to see every
day from my front yard.
Not only did he prove conclusively that there were galaxies beyond our own, he and Milton Humanson, by plotting a trend line from 46 galaxies with
their redshifts, determined that the farther distance between any two, the greater their relative speed of seperation. Hubbles Law.
Several years ago, two different groups of antronomers were observing the far reaches of the visible universe trying to determine the rate at which it
was expanding. They both expected that rate to be slowing, and both realized, at about the same time, that it was actually speeding up... and it
didn't make sense. Both camps were so sure they had gotten it wrong, that neither even wanted to tell anyone. 5 billion years ago, however, this was
not the case.
When they looked back to when the universe was around 9 billion years old, they discovered that the rate of expansion actually
was
slowing.
It seems, safe to say, that the farther galaxies got from eachother, their gravitational pull became less, and they continued on their merry way
without as much tugging from the others in their neighborhood...but something else is also happening.
(nasa image)
The one thing to note about the expansion of our universe, is that galaxies don't act as if they're flying "through" space as much as it appears
that space is actually being "created" between them. But what's pushing it apart?
Dark Matter and
Dark Energy
Semi-recently, it's also been discovered that only about 4.6 percent of the known visible universe is made up of matter that we can actually see.
Cosmologists believe about 72 percent of the universe consists of dark energy, and the other 23 percent is made up of dark matter.
(nasa image)
Basically, more than 95% of the energy density of the universe is in a form that has never been detected in a lab.
Moreover, nobody can even tell you what dark energy actually is.
Let's ask a couple questions and start putting together what I'm getting at.
What's extra? Space!
Where, exactly, is the space coming from that seems to be "injected" between galaxies?
I believe it's being created as the energy from the big bang "un-winds".
What's missing? Energy!
If the law of the conservation of energy states that energy can be converted, back and forth, into mass and doesn't go away, then where did all the
energy go from the "Big Bang" when the universe was full of very short wave gamma rays (aside from early decoupling and cancelling waves). Today,
all we see are the remnanats of that in the form of much longer microwaves. (CMB)
If space itself was made of "nothing", and that energy isn't somehow being unwound, or converted back into space itself, (creating more space),
then wouldn't they still be gamma rays?
What are We? Mass!
What is Mass? Energy!
What is Energy?.......
Us=Mass=Energy=Space?
Now to get a better picture, just imagine taking a billion miles of space and squeezing that into the size of a baseball. Somehow it's pretty easy to
see how energy in the form of a photon might pop out. Now where might something like that happen? A black hole perhaps?
Given that space beyond our finite visible universe seems to wander off into forever, it could have even been a much more massive wave that compressed
enough space to create everything we see...and black holes are just a by-product of such a calamity like the tiny vortexes you might see in a slow
moving stream. Obviously, any speculation beyond the "Big Bang", or the event horizon of a black hole, is simply that, so I'm just throwing it out
there for the mental picture.
Another mental picture of our universe might be to imagine a melting ice-cube dripping into a glass of water, where the ice-cube is mass, the cold
droplets dark matter, and the glass of water itself is space.
Lastly, as far as mental images go, imagine a coiled up spring that violently releases its energy and simply goes limp, laying out into a flat line
once it unravels.
(note: Forgive my cheezy hand scribbled diagram, as it isn't to scale, and the predicted expansion rate along the hubble constant isn't drawn
correctly. I just picked up a CD off the desk and scratched it on there for a visual representation of the basic idea. I'll replace it with a graphic
that doesn't look like I came up with it on a bar napkin after a night of drinking. Also, another likely outcome under F, is that all the energy,
including mass, simply unwinds back into space...ie:the indefinite expansion.)
What it all Means, and why it's such an uplifting feeling to think it could be true.
If we're all just energy, and energy is nothing more than bunched up space, then we can exist forever, God(s) or no God(s).
Regardless of life after death, Heaven or Hell, if we're space itself, then we just might exist , in some aware form, to reach the end of the sky in
some distant future.
Without the need to imagine a creator, or feel that this is all there is to my existence, it's the only thing I can come up with that makes sense of
my own reality.
If your beliefs beckon you along a different path, by all means, travel it.
Again, even the impossible stares us in the face every day. Space goes on forever, yet it can't.

You may have noticed that I didn't load up the main topic with hard to understand math, or concepts beyond that of a high school freshman.
If you're having trouble understanding something, I'd be glad to walk you through it, or provide a reputable source for you to look into. Science
Daily, Wikipedia, or YouTube will not be one of them.
Along that line of thinking, I also won't be willing to debate about concepts or processes not already accepted by a main stream university. (That
goes for you too Mr. Einstein was wrong... you know who you are
) Well ok, to some extent maybe but I'd really rather you didn't completely
derail my thread, and keep it confined to CURRENTLY ACCEPTED science and observation.
If it falls apart, it falls apart. I doubt myself more than anyone.
I also welcome any in-depth discussion or math beyond this first post, as it's merely a starting point, and a limping leap at a hair-brained
hypothesis.
