Physicists at CERN have discovered that antimatter falls down. Sure, it sounds like an obvious thing, but scientists haven’t yet been able to confirm that it responds to gravity in exactly the same ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

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 ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

GENEVA, SWITZERLAND—Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate—as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists ...

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 ...

Leonardo da Vinci's centuries-old sketches reveal he may have understood key aspects of gravity long before Galileo, Newton and Einstein. When you purchase through links on our site, we may earn an ...

Some of the first experiments in space dealt with gravity and weightlessness. They were somewhat simple studies to test the new environment. Alan Shepard was the first man to hit a golf ball on the ...
