Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in ...

The hunt is over. After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered ...

"A key step toward ultimately understanding which planets can stay alive, keep their water, and perhaps even, one day, host ...

Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature. By combining a specially designed neural network with precise 3D tracking of ...

Physicists have just dropped a new precise measurement for gravity. The newly published value for the strength of gravity, known as “G” or “Big G”, is significantly smaller than some previous ...

Surprising even their own connections, the 2026 Dubai World Cup extreme favorite Forever Young and the challenger Magnitude put on a fine, tight match race-within-a-race in the mile-and-a-quarter at ...

This video explores what scientists mean by a “theory of everything,” the challenges of unifying physics, and where current research stands today. Breezy Johnson's winding road leads to Olympic ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
