Faster than light!


For most of the physicists, it is hard to conceive the idea of anything being faster than light. The problem lies in the rejection of the need for a medium for light to travel. Einstein thought that any medium would eventually slow the light down. Einstein could not conceive and idea of medium which is not a physical matter.

He said that space has curves in General Theory of Relativity but he never tried to join his special theory of relativity with it. If space can have curves then it can also have density. And if you consider the space as the medium of light then any change in the density of space will change the speed of light too.

This is in response to:

Why light is (was) the fastest one?

Whatever we observe in the universe is through electromagnetic waves. That is the reason why,whatever moves faster than light can not (or real hard to) be observed. Till now there were many phenomenon in QED which were explained based on events happening backward in time. I believe that all those are nothing but particles moving faster than light. That is why we observe the outcome of the event before we could observe the start of the event itself. I always feel that we should keep it simple.

Theories that need to be unified.

Space can unify many theories but to accomplish that we need to understand that space is not void.

There are many theories and facts which seem to be different but really very tightly connected. I am enlisting them here for future reference:
  1. Light is affected by the geometry of space (gravity).
  2. Gravity is proportional to the mass of the matter.
  3. Mass is an unknown property. We are only expecting the Higgs to be found at LHC. But, if I am not going in wrong direction then we will never find Higgs. See: Higgs Boson

Medium of Light

There is no luminiferous aether but that doesn't mean that space is empty. It is made up something which provides medium to light. Einstein says any such things would slow down the light. Yes it is slowing down the light that is why light is limited to 3,00,000 Km/s.

Speed of a wave depends on the properties of its medium. Space is determining the speed of light and thus the scale of time that is why there is a sequence of events in the universe. In the absence of this limit to the speed of light, all events would have happened instantaneously.
