O.K. So the universe is currently expanding faster than the speed of light. The theory is that when the universe stops expanding, it will begin to retract to a single point, smaller than the size of an atom, and then violently explode in another "big bang". This is an ongoing process and that there have been endless "big bangs" and there are enless more to come. I don't know where I heard this from, anyone else familiar with this?

When two objects gets closer to each other, you can measure the distance between the two of them, and see how that value gets smaller and smaller and smaller.

Now my question is, how much can we reduce that distance by, before we can say they are now touching, and the distance between the two objects is 0? What's the value ...
