In a 1923 book called “The Principle of Relativity,” Albert Einstein seemed to call out to better-equipped scientists of the future to establish the truth of his mind-bending theoretical work. “Apart ...
Do you know what connects Edwin Hubble’s theory for an expanding universe and Albert Einstein’s cosmological constant? The ...
If you simultaneously drop a feather and a bowling ball in a vacuum, they’ll hit the ground at the same time. In other words, despite their mass, they’re affected by a gravitational field in exactly ...
Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...
Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...
The book under review begins with an interesting historical account of the experiments dealing with the elucidation of the sether-idea in physics, and we are led through the work of Michelson and ...
Michelson's interference experiment / by H.A. Lorentz -- Electromagnetic phenomena in a system moving with any velocity less than that of light / by H.A. Lorentz -- On the electrodynamics of moving ...
Even in some of the most extreme areas in the universe, Albert Einstein’s theory of general relativity seems to hold up. A test of a key tenet of general relativity using three stars has shown that ...
Dennis G. Hall was formerly Vice Provost for Research, Dean of the Graduate School, Professor of Physics and Professor of Electrical Engineering at Vanderbilt University. For at least forty years, ...
Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...
Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...
