I have a pretty big question:
Does all the matter in the universe has an ending?
I mean, I saw a show in NGC talking about the universe and the bigbang theory - That all was once a very small dence peeble of material of all matter in the universe untill hell broke loose and it was scattered all over the universe and every second the radius of this "blast area" is getting bigger and bigger until one day it will go back on itself to be one small dense peeble of everything.
Now... This doesnt quite speak to me... I mean... the void is endless, right?
Then if there was this peeble of everythingness in our universe what makes the astronomers think that there isnt another one somewhere far, far, far, far, far, far, far, far, far, far, far, far, far, far, far, far... (*three days later*)... far, far, far, far away in a distent... somethingness?
I mean... being that this "peeble" is "something" gives him limits; including limit of matter capacity, gravity and others...
Now, if these astronomers correct about the drawback then the drawback will have a reach limit which it cannot pass.
leaving the other matter in the universe(if there is) at their "fixed" place(if there is other matter in the universe exept matter from the big bang offcourse)...
Anyways, what do you guys think?

| Notice how you can't limit space without also limiting scale? |

yah but space is generally void, and viod is literally NOTHING, so it doesnt have to have a limit (while the matter has limit cos its 'something').
I mean... its brainbusting to just think that there`s an end to EVERYTHING... i mean, if there`s an end to this dark space, then what comes after it? a white space? more space? god?
I prefare to think that there`s no end to space and if the bigbang theory is correct then after the contrast part of our universe there will still be another universe out there that didnt get effected by this contrast... |

| "All space" and "our universe" are generally synonymous. You mean "the universe currently observable" I think, which to some ...religions... means all that exists. |

Does all the matter in the universe have an ending?
Yes, either the dark energy causes every atom to rip apart in approximately 50 billion years, or space just keeps expanding forever.
If you mean, does the universe have boundaries, then yes again. However, it doesn’t seem that there is enough mass for the universe to collapse into one point again. The ‘void’ is not endless. For the universe to be endless it must have expanded for an infinitely long time or at an infinite pace, neither of which is true.
Some scientists believe that other universes exist in higher dimensions.
Also ‘space’ isn’t a void. The inter-stellar medium contains about one hydrogen atom per cubic centimeter and the vary fabric of space-time may contain what is known as dark energy. |

if you say that the void has an ending then what lies boyond it? |

| I my own belief I think the scientists added the end so we can comprehend our massive universe and to add an explanation to to what something is. |

| No one knows what lies beyond our universe, or what happened before the big bang. We don't have any scientific tool to tell us. M theory may provide a solution. |

M-Theory is the string theory, no?
how can that provide a solution?? |

Yes, string theory evolved into M theory. String theory worked mathematically in dimensions beyond the three (plus time) that we normally experience. In M theory, membranes (branes for short) of energy in these extra dimensions collided, or “banged”, and created our universe. If the branes are infinitely large, then they would bang at an infinite number of points and create, you guessed it, an infinite number of universes.
Imagine a two dimensional universe on a piece of paper. The inhabitants, “flat landers” know only forward and backward or left and right. They are unaware that a third dimension of up and down touches their universe at every point. Countless other 2-D universes can exist beyond the flat lander’s own universe, completely without their knowledge. That’s kind of how extra dimensions work. |
