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 ...

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 ...

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 ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

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 ...

Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century. The team behind the ...

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 ...

When students learn that Albert Einstein won a Nobel Prize, the assumption feels automatic: relativity. The bending of space and time. The theory that redefined gravity and reshaped modern physics.

PARIS, FRANCE - NOVEMBER 23: Specialist in the Books and Manuscript department at Christie's, Vincent Belloy poses with the Einstein-Besso manuscript written jointly by Albert Einstein and Michele ...

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, ...
