Hi :)

I've recently had a pub chat with some mates about the theory of relativity, and two/three topics arose which were of particular interest to me.

1. "What happens on the other side of The Speed of Light?" elaboration:
In order to have the ability to pass the speed of light, an object must have negative mass. (nb: is this correct? If not, ignore the following) Which then sparked, what else must the object have? Negative velocity? Negative Time? Is there anything to support this (any/all 3)?

2. As the French would say: Le Big Bang. Universe started as some single point (singularity) that exploded. The Universe as we know it, is expanding. Will it eventually collapse, back into it's original singularity state? What will happen when it transfers from expanding to collapsing? Will time stop, then turn around and go backwards? Is this possibly what has been happening repeatedly since the beginning of everything - Continuous expansion, collapse, expansion, collapse, rinse repeat, etc.? (A friend dubbed this the "Slinky Effect")

3. and finally the obligatory.. if the Slinky Effect is true, what was "the beginning" and what will be "the end." of the Slinky Effect?

Pub + alcohol fueled discussions ftmfw. :D
