what if there was a previous universe before this universe. could a universe exist after this one exists? the big bang must have happened during the big crunch or whatever caused the universe to end. think of it! what if what happens now happens in every universe?!

The universe we are in now was created by a group of players in a game that existed in the universe before this. A group of 12 players, exactly. They come from a race known as the trolls. However, just before they could claim their prize and plant their seed in this universe, an omnipotent evil boss joined their session of the game and destroyed the door to their prize. They are currently in hiding in their session while our universe developed, all of our history and our planet's life (and any other life in this universe). The players for this universe's game session have not been chosen yet. However, the players from the last session know who they are and can contact them at any point in their timeline.

Big Crunch is a cute theory but doesn't fit scientific fact as per the laws of entropy.
We are currently in the second age of the universe, the age of stars.
A time will come when all the stars have burned out, and only black holes will remain. The matter and energy of the black holes slowly dissipates and fades and all matter left in the universe is kind of like sands blowing in the desert.

There's billions of stars in our galaxy, and trillions of galaxies all with billions of their own stars in the universe. I think one universe is more than enough.

it would really such to be in the last civilization to develop orbiting the last star

they would probably be very religious since they wouldn't see any other stars.

but their world should be made up of heavier and rarer elements that were churned out by all the dead stars.

but a black hole would might go and destroy them since there will be a lot of those in space at that point

Nope.

The real numbers are infinite, too, but you could, for example, travel forward and backward infinitely along the real number line only using integers, {...-3, -2, -1, 0, 1, 2, 3...} and thus avoid all irrational numbers.

Label each "possible universe" with a real number. Counting along the integers skips the possibility of "universe <span class="math">\frac{\pi}{17}[/spoiler]" from ever having existed, but an infinite amount of universes still exist. None of them even have to occur twice.

Who's to say all the atoms couldn't rearrangement themselves into the word "FAIL" forever indefinitely? Just because a process occurs an infinite amount of times, and there are possible variations, doesn't prevent the process from just repeating itself in the same manner over and over.

Okay, the number of possible universes is finite. Let's call that number <span class="math">U[/spoiler] for universes. <span class="math">U > 0[/spoiler] and each universe up to and including U is assigned a natural number.

Let's call the universe we're in right now <span class="math">R[/spoiler]. Given an infinite amount of time, there's no reason for arguing the possibility that <span class="math">R[/spoiler] could occur over and over indefinitely.

There is no logical reason to conclude that given infinite time, each value of <span class="math">U[/spoiler] would occur. It very well may, but it doesn't have to.

Well remember this is infinity we are talking about if there is even a minuscule chance of something happening then it will happen.

chance of this exact universe occurring infinite times = 1/x
Now no matter how big x is when you take the limit of ∞(1/x) that probability becomes a certainty.

Okay. Let's assume you're correct. Given an infinite amount of time, anything that has a chance of occurring will occur.

Given the prior posts, if the universe rearranges itself somehow into a new configuration each time it ends, there is a possibility it will rearrange itself into the same universe. With me so far?

There is also a chance after our universe has existed a second time, that it will end and rearrange itself the same exact way again. It happened once, it can happen again.

In fact, there's a chance that this universe could continuously recycle itself over and over into the same universe again and again.

But, since what you said is correct, and we're working with infinity here, there's a chance it will happen, so it will definitely happen. At some point this universe will just start cycling over and over.

But, wait. Let's look at another possibility. Let's say there's a universe where everything is like our universe except you aren't in it. There's a possibility for that to occur, so given infinite time, it will occur.

But, hey, there's a possibility that the universe where everything is the same except you aren't here could exist over and over forever, and given infinite time, it will occur.

But, hey, how can two infinite strings of repeating universes occur in sequence? You can't have an infinite sequence of A universes over and over forever followed by a sequence of B universes over and over forever.

>> No.3445009

>>3444987
>You can't have an infinite sequence of A universes over and over forever followed by a sequence of B universes over and over forever.
Actually you can. When most people think of infinity they think of an unimaginably large number. This is not accurate. Given infinite time it is possible for the two situations you outlined to BOTH repeat infinitely. In other words Infinity can contain an infinite number of distinct infinities.
