You cannot travel at the speed of light.

AnswerIf you were moving at the speed of light and looked behind you a few things could possibly happen. 1st after the flash of light that was traveling with you showing what was behind you all you would see is black, because no new light would reach your eyes 2nd you might see tiny pixles of colered light in a background of light, because light on a diagonal path comapaired to your would intercept your eyes at a certain point in time. I have heard some people say that you would see afrozen frame but I think after the light hits your eyes the energy in it is used.
A more interesting question may be what would happen if you went a little faster and looked ahead what would it look like as you cought up with light that was already moving?!
AlternateMost people know that accelerating to light speed is not possible, but we can consider the question as speculation, or as a kind of 'thought experiment' in order to illustrate some of the relativistic effects of travel at or near c. Have you ever seen a Science Fiction program/movie where the storytellers wanted you to get that time has stopped for a few people in the scene? People will be projected as if they are frozen in time; as if they are fixed in a kind of time-dependent plexi-glass. This isn't precisely what would happen to you if you accelerate to light speed (which is actually impossible) but it is reasonably close to what happens. [To observers on earth, you would look more like an infinitely thin pancake. Honest.] At the speed of light, all time would completely stop for you. It would not be possible for you to turn, or 'look', or 'do' anything at all. If you were a photon traveling through space toward earth for 10 million earth years, when you arrived it would seem to you that the trip was instantaneous.You would"NT see anything as you will close your eyes when travelling at such a speed.

If two objects moved towards each other with half the speed of light then are they moving at the speed of light relatively?
due to relativistic effects such as time dilation, an observer in either object (an observer in the same inertial frame of reference) will see the other object moving at the speed of lightsee http://math.ucr.edu/home/baez/physics/Relativity/SR/velocity.html for the mathematics behind it
Can you get off a horse when it is moving at light speed?
No, you can't it's impossible. No matter can go at the speed of light.
Speed of light in car then turned on the headlight?
Whether the car is moving or not the speed of light is constant. It is travels at approximately 300,000 kilometres per second
What formula use to get the speed of light?
well... i think that light has a fixed speed (my assumption) 299,792,458 meters per second in a vacuum. But how to calculate the speed of anything is speed = distance/ time To calculate he speed of light you need to know the refractive index (RI) of the medium through which it is travelling. As stated above light has a constant speed in a vacuum, this speed is attenuated by the refractive index of the given medium c/RI
Can you see the stars if you travel at light speed?
If you set off at light speed then if you look behind you everything will look exactly like at the moment you left.
If you are moving at the speed of light how fast will you fall apart?
If you are moving at the speed of light, then "how fast" has no meaning.
When was Dark Matter Moving at the Speed of Light created?
Dark Matter Moving at the Speed of Light was created in 2004.

Can light go faster then the speed of light?
Since light is made of light, whatever speed it goes at is what we call the speed of light. So we'll always see light moving at exactly the speed of light, at least in that particular medium.
What can scientist measure when light rays are emmitted by a moving source?
Scientist measure when light rays are emitted by a moving source the speed of light. Depending on the moving force they can also measure bending light.
How does the speed of light in the fiber compare with the speed of light in the outer covering?
The speed of light in the fibre is greater. As a result, light moving toward the outer covering is refracted back towards the core.
Was there ever any speed close to the speed of light?
Are you asking "Did any object ever move at nearly the speed of light ?" ? Electric current moving through wires, radio signals moving through cables or waveguides, and light-wave signals moving through optical fibers, travel at 0.6 to 0.95 the speed of light. Particle accelerators in Physics research accelerate subatomic particles inside gigantic magnetic rings to 0.99999 the speed of light.
Is there an equation that determines how much the relative time slows as an object approaches the speed of light.?
Time recorded on the moving clock = (non-moving time) multiplied by the square root of (1 - v2/c2). v = the speed of the moving clock c = the speed of light
Is speed of light faster than speed of shadow?
When we discuss moving faster than the speed of light, we are really talking... The speed of a shadow is therefor not restricted to be less than the speed...
Can light exceed its normal speed while refracting?
If you mean "normal speed" to be the speed at which light travels in a vacuum, then no. Anything that differs from light moving through a vacuum slows the light down to a certain extent.
Is it possible to travel at light speed?
Not if you have any mass when you're not moving.
