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, ...

Why don't we fall off the Earth?We rarely think about gravity in our daily lives.Whether we are getting out of bed in the morning, drinking coffee, or dragging our tired feet home after work, gravity ...

For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is ...

Scientists have spent sixty years arguing over why the quantum weirdness that lets atoms exist in two states at once disappears by the time you get to a cat, a coffee cup, or a person. A new ...

A group of researchers at the University of Waterloo and the University of British Columbia have discovered a potential "cosmic glitch" in the universe's gravity, explaining its strange behavior on a ...

The mass of distant galaxies cannot be determined by the brightness of their stars alone. The speed at which gas moves within a galaxy also provides a clue to the strength of gravity. When comparing ...

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 ...
