Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that question, as bizarre as it seems, could tell scientists something very ...

Scientists across New York State are planning to recreate an experiment from 1919 that proves Einstein’s theory of relativity. The Eddington Experiment allowed scientists to see stars that should be ...

GENEVA -- One of the very pillars of physics and Einstein's theory of relativity -- that nothing can go faster than the speed of light -- was rocked Thursday by new findings from one of the world's ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

Researchers at the University of East Anglia and the University of Manchester have helped conduct a 16-year long experiment to challenge Einstein’s theory of general relativity. The international team ...
