Why can't any object travel at the speed of light?
actually they found a partical that has broken the speed of light by 100th of a second.
What type of waves move faster than speed of light?
So far nothing is found to move at a faster speed than that of light.
What have we found that travels closest to the speed of light?
Neutrinos travel so close to the speed of light we were unsure for awhile whether or not they had a rest mass.
If zero mass particle have a speed c in one reference frame Can they be found at rest in other frame?
"c" is usually used, in this context, for the speed of light. If such a particle has the speed of light in one frame of reference, then, strange as it may seem, it will have the speed of light in ANY frame of reference.
Is it the speed of light or light speed?
Is what the speed of light or light speed.ANSWER300,000 km/s
Is the speed of light a law or theory?
The speed of light is a number. It was a theory before it was measured. After it was measured, and the prediction was found to be correct, it was no longer a theory nor a hypothesis. It became a "physical constant".
If nothing can surpass the speed of light in the Universe how is it possible that light on Earth can travel at the speed of light if Earth itself is moving at millions of km per second?
I say millions because of the estimations I found for the speed of Earth around the sun, the speed of the solar system through the Milky way and the speed of the milky way through the universe.
Why does light have a defined speed?
Because it takes light time to move from one place to another. The time it takes to move a measured distance has been measured, and its speed has been found to be a certain number. A contest was held to name that number, and the winning entry was "The Speed of Light".
What can be discovered if something is found which has greater speed than light?
probably all kinds of technology
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Which was the fastest the speed of light or the speed of sound?
speed of light
