Here's one I have a long time. If you travel at the speed of light and you have a flashlight wich you turn on, what speed will have the light of the flashlight? Could you actualy see it?

It is all theory, but since everything is relative, e.g. if you are walking down a moving train you are only moving as fast as you walk but are actually going faster than the train, it would seem that if you turned a flashlight on while traveling the speed of light, it would also be relative. Now, the converse of this idea is that since the light isn't a solid body, then it cannot move any faster than the speed it is already going, e.g. since the speed of light is a constant (although, some scientists believe it might be changing) it cannot go faster than itself. I suppose, since non of this can be tested as of yet, it is a question that you will probably have to just guess at.

According to Einstein's Special Theory of Relativity, nothing can travel faster than the speed of light. In the 101 years since Einstein first wrote about this, every experiment done has shown this to be true. More over, the speed of light, in a vacuum, is constant and independent of the observer. If you travel at the speed of light and flash a light bulb, the light beam from it also is traveling at light speed, no more, no less. And yes, you would be able to see it. PS: Remember, Einstein's theory also says that nothing with a mass, even a single proton, can achieve EXACTLY the speed of light. It can come close to it but never achieve it. Unless you become a particle with zero rest mass, you can never yourself achieve light speed. Sorry Captain Kirk, can't get the Enterprise to warp one...ever... unless you can prove Einstein wrong and for over 100 years, no one has been able to do so.

It will be the at same speed that you are at. If you hold the light in front of you, you will see it. If you travel facing backwards with the light advancing behind you at the same speed you won't see it even if you touch your nose with it.
1 foot per second faster and, theoretically, you will be doing time travel into the future but, nothing, including you and the light you are holding, will be there. Doesn't sound like a good idea.

What speed will have the light of the flashlight? What's that supposed to mean... the flashlight will have fizzled out by then. But if you mean any portable source of light, none, relative to you, but still the speed of light, through a vacuum.

yeah. it was proven already. i got the fact from my guiness book of world records 2000. they pased laser through a special filter of some sort. who cares anyway?
oh btw light has no mass so you cannot add your current speed to that of the supposed speed at w/c the flashlight light is supposed to travel. if you can travel at the speed of light, then turn on your flashlight, the light will stay inside your bulb. lol

as Einstein said, "its relative"
try this simpler thought:
assume there is no gravity and air resistance. if you are on a train traveling at say 40 mph and you have a ball and threw it in the direction of travel at exactly 40 mph. will the ball just float where you let go or will it travel forward?
or better yet you threw it 30mph in the direction of travel. will it come back and actually hit you on the head at 10mph?
i dont think so...

the speed of light... your speed won't affect the speed of the flashlights' light. and we see the flashlights' light at normal speed right?

1,86,000 miles per second is the speed of light. You can not go faster than this by any means,

I think so, but it's probably going to be through a different dimension.
