It is indeed a big universe. What interests me the most is the laws of physics. Does our law apply to any other race? Maybe "their" laws of physics are completely vice versa-that at an early stage, molecules/cells/atoms are structed and evolved differently.

It's possible but there would have to be multiple universes as everywhere in this universe is controlled by the cosmological-constant.

I'm not sure where you heard that from, but that's completely wrong. As you approach the speed of light, your mass increases by You must login or register to view this content.. If you plug in some numbers, you'll figure out it's impossible to reach the speed of light because it would require infinite energy.

Your attempt at explaining it sounds more plausible, but without actually getting near the speed of light we'd never know what would happen.

Completely wrong?

Interstellar space is an empty place. For every cubic centimetre, there are fewer than two hydrogen atoms, special relativity describes how space and time are distorted for observers travelling at different speeds. For the crew of a spacecraft ramping up to light speed, interstellar space would appear highly compressed.

I think you're both pretty much arguing different problems here. If we some how did manage to get to that sort of speed, we'd be killed within seconds because of radiation. However, we'd never get to that speed in the first place because of needing almost infinite energy to get there.

Oh, I see what you meant. At such high speeds, the hydrogen would pierce the ship and damage it. I thought you were talking about something completely different (the relativistic effects of high speeds on matter).

Actually, SR is one of the most widely confirmed theories of all time. Every time you use a GPS you're confirming SR.
