Isn’t the current theory relating to travelling at the speed of light say that as you approach it, things start to slow down and once passed the particles start to travel in reverse? I’m not sure if this would apply for a body of mass such as a person, it might do, but then there is the limiting factor which says nothing can go faster than the speed of light.
Mass as we know it cannot reach the speeds of light as the total energy required to push it to light speed would = more than all the energy in the universe.
You see the only way light is able to travel at the speed it does is due to having no rest mass. In other words it is energy.
You have to understand that mass and energy are interchangeable at incredible ratios.... One thimble full of sea water contains enough energy to power the world for 50 years.
Power to the People!!

Yeah, thats the hard part about "speed of light" questions. If you're not talking about light itself, then you have to be using a reference point.
So, speed of light, related to what?
I mean, if you travel 75% light speed, something travels 75% light speed in the opposing direction, there's nothing else out there at the time to use as a reference point... couldn't you technically say one of you is standing still, and the other is traveling 150% light speed?
The universe has no fixed position. It's not like it's been pinned to a giant grid.
So you have to ask, in reference to what?

Ok, what is a zero G craft?
