Sorry I'm asking this so late after the thread was started, but...

If time slows as you approach the speed of light, wouldn't that imply that you are traveling slower the faster you go?

Velocity= Distance/time

So for a ship to travel at .99C for one year(according to the ships clocks) to return to earth seven years later mean that the ship was actually travelling slower than .99C since the distance travelled would be the same, but the time the ship was gone would have increased causing the resulting velocity to be lower?

As for not being able to accelerate something beyond the light, What would happen if you got a ship up just below the speed of light and fired a gun foward? Would the bullet accelerate to lightspeed and then just stop accelerating?

What about light speed itself, light travels slower when it's going through something,i.e. the atmoshpere. So does that mean it speeds back up after leaving the atmoshpere, and if it does what accelerates it?

If light itself doesn't have any mass, then why is it affected by gravity, which is the force of attraction between masses?
