I bet you though that light was the fastest before reading the heading. I mean all of us have grown up believing that it is the fastest thing ever known to mankind. But take a while to go through our list of the

3 things that Faster Than Light 

1. COSMIC INFLATION

Faster Than Light: COSMIC INFLATION
COSMIC INFLATION

Cosmic inflation is defined as a hypothetical moment in which the universe suddenly became bigger. Now take a second to understand. For a thing such big to happen the space-time must have expanded at many times the speed of light. You might think that if this thing happens the physical laws would be violated. But no physical laws are violated because the cosmic speed limit only applies to things that move through space-time and not to the movement of the space-time itself. It’s nuclear whether inflation happened. Nevertheless, the expansion of space is making distant galaxies appear to recede from us at velocities several times that of light.

2. CERENKOV RADIATION

It is the optical equivalent of a sonic boom. It occurs when light passes from vacuum into a denser medium, such as water or glass, it slows down. In the case of high-energy particles travelling in the same direction, they often do not slow down very quickly and result in finding themselves travelling faster. What they do is that they create a shock wave that pushes light out of the way. Cerenkov radiation can be seen as a ghostly blue glow around nuclear reactors that are covered in water.

 

3. TACHYONS

Tachyon is a generic name of any particle that travels faster than the speed of light. Actually it is a hypothetical idea that was given its present name in 1967. A particle that traveled faster than the speed of light would violate the known laws of physics unless it had some extremely peculiar properties. If such a particle were possible, it would be able to travel backwards in time, and could never slow down to travel below the speed of light. Sounds exciting, doesn’t it? But unfortunately none has been found yet.

Still think that light is the fastest? 😉
