How can our Universe be infinite and there be an infinite amount of Universes?

Why don't you ask a difficult question?

I've been watching a ton of shows on the Universe on BBC and Science channel and stuff, they say M Theory and string theory give rise to an multiverse that contains an infinite number of other universes. Yet microwave background radiation shows that our Universe is infinite. How can our universe be infinite and there be an infinite amount of other universes in this 'multiverse'? There has got to be a boundary to our universe for 2 things: 1) it has to be expanding into something and 2) infinity implies that it never stops and includes everything, yet if there are other universes floating in a multiverse then our universe can't possibly be infinite. I'm looking for some clever OT peeps to help me out. I can't wrap my head around it. lo_Pine

No it doesn't
It isn't infinite

Problem = Solved

... well now that I think about it (and no, I do not know sh*t about this subject), but I'm sure that the "boundaries" are not physical. They wouldn't be expanding into each other if they don't even exist on the same dimensional plane.

Just my .02, but again I know nothing of this subject.

if it isn't infinite what is the boundary and what is on the other side?

This. The universe is flat like a piece of paper. It isn't a shpere or bubble or triangle, or what have you.

We can only guess at its actual size, but measuring that is difficult now. Could be infinite, could be finite, we dunno. Just like we don't know what caused the big bang or what existed before it becuase we can't pass the Planck Wall (physics as we know it no longer applies inside singularities, thus making it impossible right now to make any observations)

[QUOTE="killzowned24"][QUOTE="lo_Pine"] Yes it does. I literally heard a professor on BBC 5 mins ago said triangulation shows that the universe is infinite since the lines of the triangles are flat, not curved.wis3boi

Few questions
1-Isn't the plank wall strictly a string theory concept? Where in string theory, this limit cannot be crossed, but in point particle physics it can be crossed, but it creates a singularity?
2-If it's infinite, how could there have been a big bang which created our universe/the laws of physics?

My unlogical and totally unbacked up theory is that if you was to go forward far enough in the universe you'd eventually end up back where you were. Kind of like if you was to go forward on our planet for a long time.

Like in pacman where if you go off the right side of the screen your character reappears on the left side of the screen and vice versa.

The question is this: Given that God is infinite, and that the universe is also infinite... would you like a toasted teacake?

The universe isn't infinite and there is not an infinite amount of universes.

Simple as that.

Exactly! :D

i pin myself to the above, and to it i will say that the Ball is the ideal object. All planets in the cosmos are ball shaped but why? My opinion is that even the Universe is round and that's why going forward you would always move around

[QUOTE="killzowned24"] I think they were just showing that space is flat and not saying its infinite.I think it's impossible to tell the size because beyond so far light has not had enough time to reach us.chaoscougar1

We don't know enough abotu quantum mechanics and any other laws of the universe beyond our own to be able to start investigating, so until we get there, there was no 'beginning.' Time and space began at the big bang...for now. I think people who aren't astrophysicists (like all of us in here) would be wasting our time specualting on it when the greatest minds on Earth have a hard time with it.

To your first initial question of "How can our Universe be infinite and there be an infinite amount of Universes", if you can except something is Infinite then there is no restriction because its infinite :P.

But on a more serious note. We simply do not know that much about space. What we see is more than likely hugely distorted view. An example of this is that light can be bent... so what we "see" could be in different places etc. However reguardless of all of that. One theory that always amazes me, which infact has been proven true I am pretty sure, that no atom can have the same engery as any other atom in the universe.

I saw this on a BBC show with Prof Brian Cox, he picked up a diamond, rubbed it in his hand and said "now as I am doing this I am warming up the diamond, or passing along energy. This means because of *theroy I cant remember* the rest of the Universes Carbon atoms are reacting to this. As they can not be the same" which then completely blew my mind.

The biggest pain in the arse with the Universe, is that its so complicated and vast that simple english can not explain it correctly.

I agree, but planets have all a different grafity to them, some of them are just gas and still it all keeps perfectly together thats where my opinion comes from

Theories man, everything is just a theory.
