There has been an awful lot of boring threads recently about politics, so lets leave our tiny insignificant planet for a moment and try to comprehend why I believe a finite universe is an impossibility.
Thats one of the questions that we might never be able to answer, but we can guess..
Its crazy to try and imagine infinite, but can you comprehend finite universe, can you work out how its contained, with an edge or boundary and nothing beyond that?
Is that possible?
See if this doesn't confuse your pathetically small (in universal terms) brain.
Is the universe finite?
If so that means that the universe would have an edge, and a centre but...
Imagine its like a cardboard box, inside the box is all matter, space and energy, time, and laws of physics... we could drive our space ships from one side to the other, so its finite right?
but then what about the outside of the box? whats beyond the boundary? another box? there fore a larger universe, but then whats beyond that boundary? another and another and lets not forget the box is made of something, so the edge would be something of 3 dimensional depth meaning it really isn't the edge but the outer part of the box is the edge, but then whats on the other side of that edge?
still with me?
So if its infinite, then that means that there is infinite energy, matter, time, etc..
So lets set off in one direction, everything will look new for a very long time, there are 10 to the power of 80 particles in the observable universe, and its been calculated that those particles can only be arranged in a certain amount of ways and that number is estimated to be 10 to the power of 10 to the power of 70 a number so big that it out numbers the particles in the observable universe by a hell of a lot!
so even though you can arrange those particles in a very big number amount of times infinite is so big it outnumbers everything infinite times, eventually you will come across duplicate arrangements, things will start to look the same, familiar parts of space, and then more and more, until you will come across particles arranged exactly like you! then more like you, in fact if you keep login infinite amounts of you,
then you get infinite amounts of you, looking for infinite amounts of you, then you get infinite parts of a infinite universe full of infinite you, with other infinite you, looking for infinite you, in an infinite universe, it wouldn't end, the universe its self would be duplicated infinite amount of times, with each of them being infinite!
OK so now you see what i mean.. but
what about multiple universes, they would have to be finite, maybe yes but they they would all be somewhere? and what is that somewhere, how does it connect our universes and even if it doesn't, we are back to the box theory and they are within something with an outer something, so surely isn't that just an extension of our universes boundary, if the laws of physics change, if time is faster or slower or goes up or down or even around does that stop it being part of the universe?
the possibility of finite seems to me to be impossible, do you agree?
