is a constant, then if you are traveling at the speed of light and you turn on a flash light, it should travel away from you at the speed of light, away from an observer.

since we can't really test it, i'm wondering if it's possible. it seems that time can very but light cannot.

Anything with mass can't accelerate to the speed of light. But let's assume that someone is moving at 99% the speed of light and they turn on a flashlight. The light will travel away at the usual speed of light since the speed of light is constant in any frame of reference.

I frequently think about the constance of light. I am by no means a scientist but i do think a lot so maybe some one would liek to address my thoughts. Is everything (all matter) made of the same types of atoms moving at different speeds? if thats the case, are we on some basic level made of the same stuff as light?

that would be energy, i think, so i would say yes.

naw, light is energy in its rawest sense. someone travelling at the speed of light and flashing a light ahead of them would only see the light travel at the speed of light away from them. its all perfectly (if a little conveniently) explained by the theory of relativity. all things are relative, therefore, anything happening is only happening relative to you, not to others. so light will travel away from the lightspeed ship at light speed, but observed from mars, say, the light will only seem to be travelling at c not at 2xc.... get it ? i sure dont... lolol

the speed of visible light is 186,000 miles per second. if we happen to be going 186,000 miles per second and shine a flashlight forward. the speed of the light coming out of the flashlight would not be the sum of its speed plus our own speed but would remain constant at 186,000 miles per second.

the formula of e=mc2 shows that matter is nothing more than a form of light.

It does travel away from you at the speed of light... but an external observer would not see any light shine. Its paradoxical because the equations are undefined at a speed of c. If you take the example of 0.99c, the person traveling at 0.99c will see light move away from him at c, but an external observer will see light moving ahead of the flashlight at a speed of 0.01 c (because 0.99c + 0.01c = c)

Yeah.. Just like what's been said, relativity.

Time is going to BE different for you in the most literal sense of the word travelling at the speed of light, the speed of light seems to somehow be tied up with time and since you won't be conciously aware of any change in time any light you shine out travelling at the speed of light would only appear to move at the speed of light from where you are viewing it. Other people won't be able to see any extra light projected however because relative to them the light your shining never existed because of the time paradox. Time is extremely weird... You need more dimensions to explain it but I don't understand HOW exactly.

Add: Energies are different at the speed of light, different levels of energies warp space-time differently.

Light would not travel ahead of you if you were to travel at the speed of light, but then it is also impossible to travel at the speed of light or faster. The universe is like a clockwork and to travel at the speed of light or faster would be for something to avoid that.

But then if you were to travel near the speed of light and your spaceship had headlights and backlights, then it would seem like the light from the headlights would be traveling at the speed of light foward away from you, and the light from your backlights would seem to be traveling faster then the speed of light away from you.

you probably wouldnt see it but i think you probably could see stars and stuff because while your traveling your collecting light as you go along

This is so hard to imagine .
