As far as they know, nothing goes faster.
The speed of light is constant.
you cant see it
In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.In some special substances, it was possible to slow the speed of light to just a few meters per second - incredibly slow compared to the speed of light in a vacuum.
The relativity statement refers specifically to the speed of light in a vacuum.
No. According to special theory of relativity, the speed of light in all inertial mediums remains the same as that in the vacuum.
because of there speed.
The particle that is light is called the Photon. The photon is massless and can travel faster than any other particle because it has no mass. Any particle that has mass will require infinite energy to reach the velocity of light, which is impossible because the particle will have infinite mass in the process (Remember E=mc^2).
Because light has no mass.
The theory of special relativity.
The question "What does matter do when it achieves the speed of light ?" is a BS question, because matter cannot achieve the speed of light.
c - Light goes at c in all frames of reference according to Special relativity
Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.
