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...

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...

Robert Scherrer, Professor and Chair of Physics and Astronomy at Vanderbilt University: "When scientists developed the theory of light back in the 19th...

By regularly changing the pH of the system, the experimentalist is able to extract unlimited amount of work from pH-sensitive...

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...

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

"In astrophysics, gravitational redshift or Einstein shift is the process by which electromagnetic radiation originating from a source that is in a...

"Brian Cox and Malcolm Roberts. Malcolm Roberts and Brian Cox. It's one of the great rivalries of the modern era. Only not really, because one of them is a...

"In our animation, Zoe turns on the headlights of her space ship. She measures the speed of light from her headlights as c with respect to her. Jasper sees her...

Richard Feynman: "Another consequence of the equations is that if the source of the disturbance is moving, the light emitted goes through space at the same...

Peter Woit: "If, as seems increasingly all too possible, we're now at an endpoint of fundamental physics, with the field killed off by a pseudo-scientific...

"Neil deGrasse Tyson, perhaps the most famous astrophysicist in the world and a seemingly affable guy, upset teachers and started something of a Twitter frenzy...

"Albert Einstein's theory of general relativity has passed a multitude of tests over the past century, but physicists remain unsatisfied. That's because it has...

Brian Greene explains to the gullible world that, since Maxwell's theory had shown that the speed of light is constant, unalterable, space and time had to...

"The second part of relativity is the theory of general relativity and lies on two empirical findings that he elevated to the status of basic postulates. The...

Brian Cox explains the concept of entropy: https://www.youtube.com/watch?v=uQSoaiubuA0&t=138s Brian Cox explains why time travels in one direction - Wonders...

New heights of idiocy reached in Einstein's schizophrenic world: Leonard Susskind: "GR=QM? Well why not? Some of us already accept ER=EPR , so why not follow...

Natu "But thermodynamics is paradoxical. The second law, which also puts limits on how efficiently heat can be converted into work - as happens in a steam...

Scientists don't care about the truth/falsehood of Einstein's relativity - in science the post-truth era started much earlier than in politics. They need...

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