Nothing has been proven, however ! while scientist at the CERN collider may be on the verge of disproving light is the fastest thing. there are some happenings that totally suggest that light is not the fastest thing.
if a black hole being one that is a dark planet due to the fact that all light is bent by gravity so it appears black raises the simple questions. if light was faster than gravity! it would escape the planet feald if it was. so gravity is faster if light as it would escape. then the second dilemma is that a black hole can be found by the radiation that they emit so this raises two fold question that is if radiation escapes then it is faster than gravity so making it faster than light. however many will say no, simply because it has never been proven and on other foundation they do say it is not so. Bering in mind no person knows the speed of gravity nor the speed of radiation or gamma rays so, these are all up for potentially being 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.
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...
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 speed of electromagnetic radiation of all kinds, including light, is faster than the speed of anything else.
No. Nothing is faster than the speed of light. Even the fastest wind doesn't come close.
Tachyons are hypothetical sub atomic particles that can travel faster than the speed of light.
Nothing can travel faster than the speed of light in a vacuum, according to the theory of relativity.
No known particles can travel faster than the speed of light in a vacuum, according to the theory of special relativity. In a medium like water, particles such as neutrinos can travel faster than the speed of light in that medium, but not in a vacuum. In solids, sound waves can propagate faster than light as well.
