It only travels in the speed of light
Speed is a measure of the ate of travel: speed itself does not travel. So the question makes no sense.
yes they travel faster No.. No they don't. Not even close. I've heard two theories regarding things that are faster than light. Which are the expansion of the universe and a Polarization Synchrotron device that makes radio waves travel faster than the speed of light. http://www.universetoday.com/2009/06/30/device-makes-radio-waves-travel-faster-than-light/
yes, the ability of light to travel through the cable is what makes it useful. There is not some sort of hole in the center of the cable, it is a solid glass cable.
There are some particles that travel at the speed of light - mainly, the photon (the particle that makes up light), and the (hypothetical) graviton. No particles are known to travel faster than that, and it doesn't seem likely that this is at all possible.
Neutrinos travel at approximately the speed of light, which is about 299,792 kilometers per second in a vacuum. This makes them one of the fastest particles in the universe.
this question makes no sense. Do u mean a 'lighyear'?
Your question makes no sense.The speed of light in a vacuum is c = 3 x 108 ms-1In simple terms, a photon of light will travel approximately 300,000,000 metres in 1 second.It's generally accepted that a particle cannot travel faster than the speed of light.
gravity makes a rubber band travel
Light can travel in a vacuum or in any transparent material
Light will not travel into silver.
As far as light can travel
Copper is opaque to light - light can not travel though it.
