According to Stephen Hawkings (you can watch his study on time travel to answer this question) the speed of light is like the "speed limit" for the universe. Nothing exceeds the speed of light. So if you have a train that's travelling at the speed of light (which is impossible, it can travel close but not exactly at the speed of light), and a car is moving on top of it, isn't that technically breaking the "speed limit" or exceeding the speed of light? That's not possible, instead physics would "autocorrect" that and instead of having the car move fast enough to break the "speed limit", time would be slowed down, meaning the car would be slowed down, just enough so that it doesn't break the speed limit. Simply it means, if you were inside that car, time would be passing really slowly. While a week passes for the person in the car, one hundred years would pass in regular time.
No, you can't it's impossible. No matter can go at the speed of light.
Heat waves traveling at the speed of light are called RADIATION! :)
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
Speed. All photons traveling through a vacuum travel at the speed of light.
Light cannot travel faster than the speed of light, so a bulb traveling at the speed of light is not possible in the laws of physics as we know them. If it were somehow possible, the bulb may emit light, but we cannot definitively predict what would happen under such extreme conditions.
Nothing

No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
The speed of electromagnetic waves is constant in a vacuum, traveling at approximately 3.00 x 10^8 meters per second, which is the speed of light. This speed does vary depending on the medium through which the waves are traveling, with light moving slower in materials other than a vacuum.
Nobody knows for sure. We have never witnessed a physical object traveling faster than the speed of light.
If you are moving at the speed of light, then "how fast" has no meaning.
When the light is traveling through vacuum.
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).
Electrons are able to travel close to speed of light.
Dark Matter Moving at the Speed of Light was created in 2004.
