A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all. Instead, it could arise from entropy, a measure of disorder. The theory, ...

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and ...

Root explores how Earth’s gravity field is constantly changing and what these variations reveal about our planet ...

"General relativity is likely incomplete for describing the very first moments of the universe, when quantum effects should also matter." When you purchase through links on our site, we may earn an ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...

Gravity is the unseen force that shapes the universe, yet we rarely give it much thought. First explained by Sir Isaac Newton, it is the pull that draws objects toward one another based on their mass ...

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the ...
