Sabine Hossenfelder: "The solution of general relativity that describes the expanding universe solves Einstein's equations on average; it is good only on very...

Physicists do know that the speed of light is variable, not constant, but they also know that abandoning the falsehood would be suicidal. So Joao Magueijo...

Michelle Thaller (12:02): "The speed of light is so constant that the Universe actually changes everything so that you would never see it going any other...

In explaining the relativistic Doppler effect for light, at 6:09 in the video below, Brian Greene derives the formula �_obs = 1/Δt' = γ(c-v)/λ where...

Here is water placed in an electric field. Vigorous cyclic motion can be seen, obviously able to produce unlimited amount of work at the expense of heat...

It all started with the false constancy of the speed of light. Einstein plagiarized ("borrowed") it from the Lorentz equations, called it "postulate", and...
