Is there a new universe?

there can't be. "uni-" means one (imagine having different UNIforms for a team). there IS, however, the theory of multiverses, that you might be interested in searching for and having a read about.

Just one doubt about your  theory,how do you know that only one big bang has taken place as you say that a second one is coming up???And tell me how you would accelerate something to the speed of light as the mass would become infinite.\nAnd according to your theory the total energy in the universe will go on increasing.You are stuck in a viscious circle!!!

the radius of the observable universe is about 46 billion lightyears.  currently, the expansion of the universe is accelerating not decelerating.  any observers existing in the very distant future will only be able to see bodies within the galaxy that is the result of the merger of the milky way and andromeda.\n\nmaybe these sites will help.\nhttp://map.gsfc.nasa.gov/m_uni.html\nhttp://www.astro.ucla.edu/~wright/cosmo_01.htm\nhttp://universeadventure.org/\nhttp://www-supernova.lbl.gov/\n\ni have something else for you to think about.  the universe is 13.7 billion years old yet has a radius of 46 billion lightyears.

i'm not sure at all(I don't think anybody is), but i think that there might have been other big bangs. Maybe the universes are linked by black holes?

I think it is some calculation based on the most distant objects we can see (with radio telescopes etc.) and interpretation of 'background' radio echos attributed to the big bang. One figure gave the universe a diameter of 26 billion light years.\nI have heard about the big bang theory and people say they have evidence and the scientist are not really disputing it. As a lay reader this will do it for me.\nBut other possibilities do exist that remain consistent with what we have found out about our universe.\nIs this the first big bang in this universe, could we be expanding in the wake of the last such explosion that occurred in this part of a larger universe?.\nHow many universes are there?\nFrom a mental point of view I find it hard to assign a boundary to the universe and just accept there is nothing beyond it.

Think of the universe as a giant bubble. Outside the bubble is nothing. nothing exists. no space. no time. Even though there is an edge to the universe, you cant reach it. If you started at the earth and went in a straight line. you would eventually come back to the earth. Also, we are not the only universe. there are other bubles. too. they are in the same nothing as ours. But you could not travel to other universes.

It's amazing isn't it?! It's so beyond our technology to fully test the theory though. I do however believe in parallel universes because math proves that you can have more dimensions beyond what we possess. Have to be able to open your mind to understand, ya know?

Using mathematics to determine the chances of life elsewhere in the universe, one estimate determines that there are approximately 10^75 advanced societies.  If true, then it is very likely that there is life beyond earth – even advanced life forms.\n\nSteve\n:-D

physically the universe has no limits . but still it is expanding with enormous speed . you can go to this link : http://en.wikipedia.org/wiki/Space and find out whatever you need about space . good luck

That covers only one Galaxy - Milky Way\nThe whole universe is yet to be discovered .... by humans

Beyond our universe is a multitude of other universes moving through a multiverse.

The most recent investigations (WMAP) about the shape (geometry) of our universe show that it is FLAT, meaning that it will expand infinitely, parallel lines never meet, etc.,.\n\nhttp://map.gsfc.nasa.gov/m_mm/mr_content.html

Wow, what great questions.  Just so you know, we don't know the answer to what was before the big bang.  One idea is that our universe expands, then contracts on itself, over billions of years, and the whole big bang repeats over.  In other words countless universes preceded our own.

It does not end and its growing, before you try tackling such a question, answer the micro-level questions of the same kind.  The universe encompasses all that exists, and by default then, it is largely unknown.  We don't know where the universe ends, and all evidence points to it being endless and growing, therefore we make a conclusion based on a portion of the information actually needed.

Yes, I think it is possible.  We live in such a great universe and there is probably another life form out there.

My current belief is that there was time before time as we know it. Something "had" to exist before the cosmos as we now understand it. The Big Bang wasn't the first, nor the last. In order for that to occur, yes, I believe that it was the result of a black hole to end all black holes reaching its limit. It's a thin, untested theory, but it is what I am with until something better is derived. This is consistent with my answer to your later question. That is I haven't thought about the possibility of one universe existing within another. It is plausible in my mind though and interesting enough to think about it for years to come.

The thing is ... a parrallel universe may exist. We cannot prove it one way or another ......YET! :) How do we know that another universe and our universe and many other universes .... do not exist in a metaverse? And if so .... maybe something like distance etc. exists in that metaverse ... which imparts some of it's qualities to our own universe and indeed to any other universe within that metaverse. Hence ..... we may not even have a void outside our universe at all.
