Here's a scenario: A crew travels through the Universe in a spaceship capable of 100% light speed. Relativity states that anyone inside of said craft will experience time dilation, possibly to the point of time coming to a complete stop for the crew/passengers. But time passes much quicker for the outside Universe in relation to the crew/passengers. So, in theory, the crew could survive the death of the Universe itself. Is that possible...assuming, of course, the ship could actually achieve light speed?
