Where does space end? And is there such a thing as a parallel universe? For a science debate issue/project topic.

I think that space is allways changing because of dark energy and dark matter. Dark energy is a force that push's the universe apart.Dark matter is the force that hold's every thing together so you realy cant say exactly where the end of space is,because it is allways changing.

 

Scientist's belive that parallel universe's are stacked on top of each other like some one stacking CD's, and that every universe has a membrane that keeps them apart.

 

 

Some belive that two parallel universe's smashed in to each other which could of caused the Big Bang.

I think the belief is not that universes have membranes, but that they are the membranes themselves. It's called brane theory, I believe. Where two universes are like 3d branes (3 spatial dimensions at least) that float in a higher dimensional space, where we only see what is within our universe. Every once in a while the two universes might collide or touch, causing a shock wave/big bang like event that wipes the slate clean, so to speak.
