can anyone prove that the einstein's theory of relativity is not allright anymore ?

Question

I think that the velocity of the light is not as that it was some years before and the velocity of light is varying day-by-day. So why could be the theory of relativity ok today?

Answer 1

Special Relativity refers to fact that all observers see light traveling at the same speed, that they experience time differently (dilation), lengths are contracted, and that simultaneous events in one frame are not simultaneous in another. This has been confirmed repeatedly over the last century. Whether that is varying day to day, I have seen no evidence for it, and it is irrelevant to what the theory describes. As for the guy above, scientists have NOT shown information to travel FTL, I don't know if he is referring to quantum entanglement or phase velocity, but they convey no information and do not disagree with Relativity.

Answer 2

I can't prove it but I think you are right because of dark energy and dark matter and the increasing inflation of the universe. The theory of relativity will still be OK because the laws of nature will stay the same, we will just have to adjust the numbers a bit.

Answer 3

The speed of light is a fundamental constant of the universe, is does not change. I have seen no experimental evidence to suggest a change in the speed of light.

Answer 4

cause it's all relative. even if the velocity changed; the light on the front of your 2000mph space craft is still the same speed as the light passing by your 2000mph space craft.

Answer 5

You may think the speed of light is varying.

But others are actually measuring it. And it is not varying.

Which proves that your thinking is faulty.

Time to get your brain repaired.

Answer 6

scientist have proven things can go faster than light .
