Parallel universes cannot exist within the same space due to the properties of atoms. However, other universes could coexist in different spaces. But the real question is what exists outside the multiverse.

The universes may not exist in the same place as we see it, but in the same place yet on different universal frequency ranges, so to speak, perhaps. That doesn't mean that if our earth would disappear all the other earths in all the other universes would as well - the atoms are not shared interdimentionally, but there may be identical earths in different dimensions that exist in the same physical place that ours does. Perhaps the atoms even are shared between universes, as this article states:


If the atoms do not technically exist in more than one place in once, they may seem to, as is the case with [url=http://www.research.ibm.com/quantuminfo/teleportation/Quantum Mechanics' atomic property duplication[/url].

Ever watch the movie men in black? A univers can be as small as a marble. If so it would be possible for 2 universes to coenside within eachother all the while remaining compleatly seperate. Here's a question though. where does space end? is it like pac man where when you get to one side you pop out on the other? is space round? how big is space? And correct me if i am wrong but a univers is when object rotate around a star, thouse objects could be other stars planets and debree.

I wouldn't base my ideas off of games and movies for the sake of avoiding ridicule if I was you, but in this case, who knows. Supposedly, the universe never ends, so it's like walking on an inverted earth, meaining that if you keep going in one direction you'll end up where you started (although I may be wrong and it's a bit hard to imagine).

Definitely there may be another universe, because what we humans know about the worlds other than the Earth is just like a specke or a drop of water in an Ocean. We may come to know about another Universe in case if the Science has grown enough to reach beyond the billions and billions of stars and galaxies.

Listening to audio books such as A Short History of Nearly Everything, it's amazing how much we know about the universe without even leaving our solar system. On the other hand, it's a bit depressing, since it really puts the size of space into perspective. The author of A Short History of Nearly Everything says that he thinks it's unlikely that humans will EVER leave their own solar system, simply because it is so unbelieveably massive (apparently the length of the sun to Pluto is only a small faction of the actual size of the solar system).

i really think there is more than one universe. it's a bit selfish of our part,humans,to assume we are the only ones that live in this giant universe,don't you think? i'm pretty sure that we have company somewhere in space and i also thing that we probably are a kind of a "recent" aquisition,i mean,the universe has bilions and bilions of years,numbers that i can't even tell and where we are,with only a "few" of them,comparativly. and we don't know a lot of our own earth,much less from the universe. so we never know.. maybe some day other habitants from this or another universe come knock on our "door" and then we will see.

There has been a theory put up in the recent years. They call it , the string theory. According to that theory, it is possible to have 11 dimensions. While we would get ourselves lost if we start getting to imagine about the fourth dimension itself, things could get pretty complex moving to eleven dimensions. And this theory ,does support the idea of parallel universes . And with worm holes, one can get to see parallel universes in a matter of time. There are an ocean of ideas to be explored which are in the same league as Parallel universes. But it would take an Issac Newton or Einstein to get that far, i guess ...

The term "Universe" is just to describe what everything there is, is in! You cant say there is another universe because then these "two" universes would just be inside THE universe which hold the two smaller universes.

is very difficult to explain, estiphen hockings said in his book that the univers vas born by the big bang, but only this univerce, to have the existance of another there should be another bigbang, in my opinion
