You cannot travel at the speed of light. However, no matter how fast an object travels light that it emits will always travel at the same speed, ~300000 kilometers/second.

186,000 miles a second. It's not just a good idea, it's the law.

I hope this is like 100 years ago when we couldn't exceed the speed of sound.

Light travels at the speed of light, and it has mass. Why else would be affected by gravity?

[go star go]

not necessarily. scientist have recently arrived at a new theory that the speed of light varies and this throws a monkey wrench into the theory of relativity.
