Am I to believe that if you converted all the mass in the universe to energy, that energy could be stored within the period at the end of a sentence?
Nonsense questions will have nonsense answers. So let me just pick one randomly....hmmm....
I'm going to go with yes, but only if the ice-cream to violin ratio is below -8 Kelvin.
EDIT: I see where you problem is. You're hung up on the "primeval atom" thing. So far as we can tell, the universe is infinite. It has ALWAYS been infinite. At some point everything was closer together but it was still infinite. How is that possible? I've brought this up before but here's how it was explained to me by a physicist:
Imagine the number line.
...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...
It stretches off in both directions forever. You can never reach the "edge" of the number line. Count to a mind bogglingly high number and you can always count 1 more. The universe is like that. You can always keep going further.
Now, multiply every number on the entire number line by 2 and what do you get?
...-10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10...
Now all of the numbers are twice as far apart from each other but the number line is still just as infinite as before.
The universe is expanding but there is no edge. It is not expanding from a single point and it's not expanding INTO anything. The "big bang" happened everywhere. Scientists don't know what happened before the expansionary period but there doesn't necessarily have to have been a primeval atom. In fact that concept doesn't really make much sense.
