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 ...

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 ...

NASA once sent over 2,000 jellyfish into space to study how gravity affects biological development. The unusual experiment ...

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 ...

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 ...
