[QUOTE="dexterace, post: 804025, member: 11222"] I just wanted to comment on this statement. You CANNOT go faster than the speed of light. What you are referring to of course is that the person travelling very fast is noticing length contraction in the direction of movement as compared to a map that was made by someone at rest (from the Earth). Of course that person on the earth will just see your time slow down, etc. Therefore, it's possible to travel around the Milky Way Galaxy in your lifetime, just that when you come back to Earth (if it's still there) it could be millions of years later. So it appears that you are travelling faster than the speed of light when you really are not. It is incorrect to say that you can go faster than the speed of light, because of one reason. If I were travelling in a fast spaceship and tried to go as fast as I could, I could still turn on a flashlight (or headlights, etc) and measure the beam's speed to be always the speed of light and that beam WILL be travelling faster than the spaceship (in vacuum). Everyone will agree, no matter what speed they are moving, that a beam of light will travel at the same constant speed (and that speed will always be faster than anything with mass). [/QUOTE]
