Topic: Educate my dumb ass on the big bang theory

I get the obvious part of the big bang theory – everything was really condensed, then exploded. Things happened to make stuff bigger than hydrogen form.

What I don’t get is what happened before that. So there was this mass that contained everything – for an infinite amount of time – then suddenly, something caused it explode. That’s the part I can’t grasp, the spontaneous beginning with no external stimuli.

Can someone fill in the scientific part I’m not grasping?

Absolutely nothing.

What's south of the south pole? You have to have time for there to be a "before".

Think of it as more of a kind of edge than a beginning.

The Big Bang was a singularity and as such destroys all information that we know how to get at. There is currently no way for us to know anything about the singularity that started it all other than it existed. The singularity could very well have existed for only the smallest of times before it became unstable and blew itself apart or it could have existed for billions of millions of years before a configuration of sub atomic particals caused it to blow apart, we simply don't know and may never know.

There's no such thing as absolute time. Also, anything about previous universes and whatnot is unverifiable and too damn confusing to worry about when explaining this.

As I understand it, the explosion of the singularity was an event that, like any other event, had a set probability that was ultimately realized because time was not a limiting factor.

If anything could be said to have caused the big bag, it's blind luck.

Also, keep in mind that, like evolution, the big bang "theory" is only a theory in the strictest scientific sense of the word - it can, for intents and purposes pertaining to everyday life, be taken as fact.

If the big bang theory needed to be proven in a court of law, for example, it's existance could easily be proven beyond reasonable doubt.

Also.

The big bang was not an explosion from a single point of space, it was the complete appearance of all space in the universe at a single point in time, t=0.

By which, there can't be anything before it, nor is there anything outside it. It's an edge of space and time.

Boy, that movie had absolutely no bias at all!

Yes, there is an infinetely small chance that the conditions were just right for life to evolve. But even small chances can happen. Example, my friend was playing POGs with his friends and managed to hit the stack of POGs, flip about half of them over, and have them land back upon the stack in the same order they were in, just flipped over. In short, just because Minute chance != impossible, does not mean that God = Y || God = y.

I wouldn't call it "biased", but it is fantastically ignorant.

For example, saying facetiously that the galaxies could float around without bumping into each other "just by chance" is out and out hilariously ignorant of the mechanisms by which galaxies actually do move, IE gravity. Furthermore, galaxies DID bump into each other and continue to do so to this day, as seen here.

The entire flash and every point in it is nothing more than an elaborate and sarcastic way of restating the watchmaker fallacy.

I believe the way you phrased it is that the south pole would be the end point of south (though I can interpret it two other ways). The problem is, if I interpret it that way, the question is phrased in a way that pretty much means “how close are you to point x?” Another way of looking at this is a (Euclidean) ray instead of a line.

With my untrained mind, I see time as a line (not a ray). The big bang would be a point on that line. From that point on to the left, I see the singularity. From that point to the right, for the next thirteen billion years or so, I see the universe as it exists today.

This untrained mind has issues with this. See, my mind can picture pattern, something that is circular, and something that is stagnant.

The pattern thought lends itself more to Steady State theory, which my untrained mind can grasp. This really wouldn’t be considered the big bang (I hear this was disproved anyhow).

The circular idea yields two answers. The first would be that the universe is constantly being created and destroyed. This is the big crunch theory, which I also believe is disproved. The second is a pattern that starts at one point, and keeps on reacting until it reaches its original state. The problem with this is that it yields the same end result as stagnation – it’s impossible to change without external stimuli. The big bang would never happen at all with the second idea circular idea.

Stagnation is just that – it was always there, it will always be there. Nothing changes. This , of course, would negate the idea of the big bang because hey – there would be nothing to cause it.

What I get from you is that I should look at time as a ray instead of a line. Is what you are saying that time essentially stopped right before the big bang? Does this mean that time is slowly speeding up, in a matter of speaking (so is entropy linked to time)? Something about time being based off of relative speed to everything else, so if everything is in the same place, time doesn’t exist (just a guess from the information given)?

Note: I apologize in advance for trying to make sense of things with my limited knowledge – that’s why I’m making this thread. To find out the answer!

The thing that I don't get about the Big Bang, and I think what Diadem's got in mind as well (Though I could be mistaken) is the law of conservation of matter, or rather, matter and energy can neither be created from nothing nor destroyed to nothing. There's gotta be SOMETHING there in the first place for everything to act off of.

Admittedly, the fact that we can't tell what was before the big bang goes in its favor, but still. Confuses the hell out of me from a scientific standpoint.

What's worse, I can't even begin to follow my own thinking here to explain it in the first place. Science makes my head hurt...

The universe is, by definition, all there is. Time is a property of the universe. Without the universe, time cannot exist. The universe began at the Big Bang, as did time, which means that the universe has, quite literally, existed for all time. In other, simpler, bolder, more axiomatic words: There is no point in the past where the universe has not existed.

Also, Diadem, the current cosmological model seems to indicate that the matter of the universe is actually accelerating away from the other. There will most likely be no Big Crunch; the universe will expand until it accelerates all matter so quickly that it will overcome all nuclear binding forces and rip all matter the universe apart.

Well, that, or heat death is the ultimate fate of the universe. There's still, of course, vigorous debate about the matter.

Without the presence of dark matter, there isn't enough gravity to sufficiently stop the expansion of matter and put it back into one big crunch.

But unless there was some gravitational quanta wouldn't there always be some graviatational force? It seems that while it may take an unbelievably lng time eventually it would stop the expansion.

There has to be some part of the physics that I am missing.

I vaguely remember reading a while ago about the concept of some kind of "anti-gravity", which purported to explain why the Universe would continue to expand. Apparently its power increased over a longer distance. I can't seem to find any information on this online, so I suspect it was bullshit, or impossible to prove in any case.

We don't know the shape of the universe. For all we know it may be accelerating away from everything only to eventually smash into itself later.

You're still thinking of the Big Bang from an apparent outside looking in. That's incorrect. You're also still thinking of time as absolute, instead of relative. That's also incorrect.

Try reading up on some general relativity, that will help a lot.

What I'm saying is that time is a part of the universe, just like space. The universe contains all time, as well as all space. If you think of it this way, the big bang, where all of space is a singularity contained in a single instant of time, t=0 where t is greater than or equal to 0, is an edge to the universe. Or at least, a limit.

It's hard to explain if you've still got the Newtonian common-sense brain bug thing happening.

Some theorists believed/believe that every so many of billions of years the entire universe condenses into that same small little point of matter. Then after so long it explodes again. Although there is no way to prove it, and it seems very unlikely due to the fact that matter is accelerating away from the point where they believed the big bang originated from. If it were actually as they said and occured every so often matter shouldn't be accelerating it should be decelerating. So if you think of it as happening every so often, the line of time would have a bunch of dots along it plotting the different big bangs. If you think of it as a random chance then there would be one dot with not possible way of determining what happened previously or what may happen in the future.

Also that energy that is causing the universe accelerate apart is known as dark energy, i'm pretty sure it's because they had nothing better to name it. Similar to dark matter.

Simple fact (As already stated), there is no t < 0; we can only do current state physics back to Planck time, t= 10^-42 s. Time space, and pretty much everything came at the emergence of spacetime, which Einstein described well, but you need all the constants he had originally dropped.

What you are asking is also more of a religious question seeing as no science can answer "why" questions. What was before the universe, nothing that matters to any of us.

Universe will acclerate away, as it stands, we'll lose sight of non-neighborhood galaxies in a few 100 trillion years. Mainly from the redshift of light moving the emitted light to extreme red where the wavelength is larger than our solar system. we may also see the heat death, but not confirmable as of yet from the microwave background radiation. Furthermore, our local neighborhood of galaxies will not disappear from our sight, because the combined mass-gravity of the local group far exceeds the stretch of the universe as a whole, and remember, it's space and time that stretch, so the paricles within will increase in size so that the mass remains in the same space.

The explanations are still lacking, and the full explanation is too complex to be typed out here, what you need is an undergraduate level astrophysics and cosmology courses to understand the question better.
