The Universe

Hm? Your response doesn't rebuke my analogy.
In my analogy, the human is a universe. A human can only be born once, a universe can only have one Big Bang.
You say that a different human can be born, but it is a different, separate birth. Likewise, there could be another Big Bang, but it would create another universe.

Your rebuttal argues for a multiverse, not for a single universe that can have multiple Big Bangs.

According to the theory, the big bang was the creation of time, space and matter. Its hard to see how another big bang can occur in this universe when time and space already exist. Man, my head is starting to hurt.

Although I can't say for certain that there cannot be another "big bang" type of event in the universe, I'm going to agree with Tegumi here because as far as astronomers know, another one won't happen. It's predicted that what will be left after all the stars die and black holes evaporate, will be a cold lifeless universe where nothing happens. That will be in about 1092 years (that's right, 92 fucking zeros).

Fun Fact: No one ever says "In a universe PERPENDICULAR to our own." It's always parallel.

Hmm, learned a new English word there. Still, that is interesting in it's own way, and makes for some weird theories. According to a perpendicular universe, it would either have the same starting point, have one single point in their history that is exactly the same (a crossover), or face the very same end.

The crossover situation is especially interesting, cuz' that would mean that two completely different paths of progress would lead to the same result, and then the continuation would return to differ.

Lol, let's add parallel universes to that as well. That'd be some crazy shit if you'd put it on paper, like an endless grid.

Big crunch(s) open up possibilities for multiple big bangs.

According to this theory, the universe will one day stop expanding. Then, as gravity pulls on the matter, the universe will begin to contract, falling inward until it has collapsed back into a super-hot, super-dense singularity.

Edit; This is coming from the idea of one big bang/big crunch per universe. After a big crunch our personal universe ends and a new one is created at the next big bang.

I've heard that theory is being pushed aside by scientist, since they've realized that the expansion of the universe is accelerating rather than slowing down...

Amusing; I don't think this was mentioned in the book I read, the last chapter deals specifically with the end of the universe. I'll re-read it, and if there's nothing, I'll e-mail the author about it. It'll take him a few days to respond though.


Precisely what I would have mentioned, if I wasn't so unsure of the science behind "the big crunch."

That's a rather horrid way for a species to die, freeze to death by their home simply drifting from their sun.

One could argue that the theory can't be tossed completely as the universe may slow down it's expansion but, I won't be that person. As I'm very far behind on research regarding the universe. Too much happening in the body politic.

At least we won't be bothered by out, since you and me will die much earlier, and if our specie is still stuck on earth at that time (and if we haven't already destroyed ourselves), we will burn when the Sun begins to swell in about 5 billion years or so. =D

True, it might slow down, but since I do not know what the theory is built upon, I can't say why it would. As I said, just something I read.

Don't worry about that happening. The sun has got us by the balls. It won't be letting go.

I wish it would, they're starting to sweat.

High School debating tactics ftw! Let's talk about the person while disregarding the issue at hand and dismiss them because of their appearance!

Just fucking pathetic.


Which isn't happening, otherwise, the increase of gravitational forces over time would be noticed.

Dude, it seems like you believe that the Big Bang is some sort of miracle machine that just create stuff like if it's a factory pumping out candy.

The dense mass that later became Big Bang was most likely not so different from some existing celestial objects that exist today; most likely it was something resembling of a Black Hole, though a very, VERY large one. I do not know why it would explode, but it probably has something to do with fusion and fission reactions (like most other things in space (and yes, this is really vague, since I do not dare to speculate over this since it's really nothing I know anything about))

The "Big Bang" didn't create things either; when it exploded it threw matter out in the universe, generated heat, made matter on the smallest level react with each other etc, which formed some of the chemical elements that exist in this world (mostly Hydrogen I guess) which later fused together to form other chemical elements, blah blah, you should know the drill. Anyway, point being, the Big Bang can't still be "creating things", since all it did was throwing matter out into space, and as the universe is getting cooler and cooler, chances are that "something" will not just form anywhere anymore.



And what is making the universe expand faster? Well, I dunno, I could look it up, but I could also guess that it is because there are no drag or friction that would cause the universe to slow down, and therefore it will continue to expand forever. Seems logical enough to me.



Of course there can be more dense points like the "Big Bang" source, but they are probably VERY far away. If they existed at the same time as the Big Bang source, they would probably have been drawn together and fused (hey, maybe that is what caused the Big Bang) unless they were separated by truly massive distances. Or maybe they wouldn't, I'm not to knowledgeable on the Laws of gravity on such a scale.



And I can answer you like this; there are things we cannot see that still exists, so your argument is invalid. Dark matter can't be seen, as an example. And what Dark Matter is I don't think is settled, but you can read about it instead of making wild assumptions.

Also, it's true that beyond the borders of our universe there might be points similar to the source of our Big Bang. But do you understand what mass and what gravity that thing would have? I mean, really. It gotta be pretty far away from the borders of our universe. But that is not impossible; it might work like a normal galaxy; one point of massive gravitation that have several universes circling around it. And there being a countless number of those as well.

There is nothing saying that our universe is not just a single speck in a super universe, which is inside a super massive universe, and the list can go on forever.

The universe is expanding because of something called dark energy. The theory of the Big Crunch was based on the assumption that gravity would eventually slow all of the matter in the universe, and then everything would clump together continuously until another big bang-like singularity is created. But the universe is not slowing down. Everything is accelerating away from everything else; it's not so much about expansion. And the cause is what they term "dark energy".

As for why there couldn't have been any more big bang singularities, the big bang singularity is supposed to be infinitely dense. What does that mean? Anything else that was around it would have been sucked in by the mind-numbing amount of gravity that the singularity had, no matter how far away it was. If there were more, they became one. Just one.

One more thing: there is NO "center of the universe". I repeat: there is NO "center of the universe". The majority of the posts I've read here have a common misconception. The Big Bang "explosion" isn't a normal explosion. In fact, the only way we can understand it is if we think about it as an explosion. An explosion has a central point, and the material expands radially outwards from the center. But that's not what happened.

Like I said earlier, the big bang "explosion" created SPACE AND TIME. No one has commented on that for some reason, but that's what it is. The Big Bang couldn't have happened in any particular place in the universe because there was no universe! No space, no time, no matter. Just the infinitely dense singularity.

You can see it better this way: if I was to take an advanced, super-powered telescope that can see into the far reaches of the universe, and I point it in several directions, the universe would look the same in all directions. There isn't more of the universe on one side of the earth than the other. And it's like that even if I was to use this telescope on Mars, on Pluto, or on a moon in the Andromeda galaxy instead of on earth.

There's a balloon experiment about the universe's expansion that you should look into if you're really into this stuff. I'm too lazy now to write about it. Wow, I had a lot to say. I love discussions on the universe!

Interesting theory. Purple screens could make your head explode. Remember the Porygon episode of Pokemon, a lot of Japanese Kids were rushed to the hospital.

For all I know. Even Chou Tenggen Toppa Gurren Lagann fits inside the whole universe. Yes, the universe is infinite.

I believe I remember a certain theory, can't quite recall what it's exact name was, but I believe it was something like the rubber band theory, that the universe will continue to expand to a certain point then stopping, and will revert back to it's original state. Unless that's what FPoD was already mentioning earlier.

edit:yup never mind
