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...
No, if you were able to travel faster than the speed of light, you would not have a shadow because light would not be able to keep up with your speed to create one. The theory of relativity states that nothing with mass can travel at or faster than the speed of light.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
* The speed of light in a vacuum, * The speed of sound,
The speed of knowledge/information travels faster than the speed of light.
Nothing has ever gone faster than the speed of light.
Concorde is a commercial supersonic aircraft that can travel at speeds over twice the speed of sound, but it cannot fly faster than the speed of light. According to Einstein's theory of relativity, nothing with mass can reach or exceed the speed of light in a vacuum.
No, not quite. We know that for sure, because nothingmoves faster than the speed of light.
The object casting the shadow moved, the source of light moved, the object upon which the shadow was cast moved, the shadow was viewed through a prism or a piece of glass that moved, stress or fear influenced the perception of the person seeing the shadow, some translucent or semi-opaque cloud or puff of smoke moved across the field and momentarily highlighted the shadow, or the shadow was never really there in the first place. There may be other possibilities, but they are not obvious to me at the moment.
No. Nothing is faster than the speed of light. Even the fastest wind doesn't come close.
The speed of electromagnetic radiation of all kinds, including light, is faster than the speed of anything else.
Faster than the speed of Sound!!!!
Tachyons are hypothetical sub atomic particles that can travel faster than the speed of light.
