Ever since Einstein: nothing is faster than light. In 2011, an experiment at CERN seemed to prove the opposite - until the ...
One of the most basic assumptions of fundamental physics is that the different properties of mass—weight, inertia and gravitation—always remain the same in relation to each other. Without this ...
An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of ...
Gravity causes galaxies to rotate. Astronomers can study the speed of stars at different distances from the galactic center to look for evidence for dark matter or other new physics. The majority of ...
Albert Einstein might be astonished to learn that NASA physicists have applied his relativity theory to a concept he introduced but later disliked namely that two particles that interact could ...
Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...
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 ...
Add Yahoo as a preferred source to see more of our stories on Google. The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to ...
