The laws of physics say you can't travel at the speed of light. It's impossible. You can get arbitrarily close, but accelerating an object with a rest mass to the speed of light in a vacuum would take an infinite amount of energy.
I'm going to recommend a couple of books to you that may answer what you were trying to ask. Obviously most modern physics texts are going to discuss relativity to some extent, but the Feynman Lectures on Physics is a good investment if you're interested in physics generally. Alternatively, for a more readable explanation that's not as rigorous, the Mr. Tompkins books by George Gamow attempt to explain what the world would be like if certain physical constants were different... in particular, in one he shows what it would be like if the speed of light in a vacuum was around 60 miles an hour. Finally, you might try Geometry, Relativity, and the Fourth Dimension by Rudy Rucker if you can find it at your local library.
According to the theory of relativity, it is not possible for anything with mass to travel faster than the speed of light in a vacuum.
Darkness does not actually travel. When we perceive it as moving, it is the absence of light that is spreading. Light can be blocked or absorbed, creating darkness, but darkness itself does not have a speed at which it travels.
The answer to "What is the fastest thing that can travel?" is light. Light can travel faster than any other thing in the universe!
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
Yes, light can travel through a vacuum. In the absence of a medium, light behaves as an electromagnetic wave, moving at a constant speed of about 186,282 miles per second.
Not if you have any mass when you're not moving.
When it is moving through a vacuum.
Because when moving at the speed of light, time stops for you and you can no longer measure speed (distance covered in a certain time).

No. They never traveled at the speed of light, and have always appeared tired.
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.
No. Nothing with mass can travel at the speed of light.
If you are moving at the speed of light, then "how fast" has no meaning.
The answer to "What is the fastest thing that can travel?" is light. Light can travel faster than any other thing in the universe!
It is not possible for any physical object to accelerated to the speed of light. But in one particular extreme it is possible to slow the speed of light according to the Bose-Einstein Condensate. The question better stated would be "Would an independent observer see light emanating from a source that is traveling backwards at the speed of light?" Yes. Light always travels at the same rate. No matter how fast you are traveling, any light that you emit will always travel at a constant rate. (note that it's not possible for a physical object to actually travel at the speed of light in a vacuum).
