In 1697, Newton solved a challenge overnight — but the real breakthrough came from a deeper idea that would outlive them all.

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Einstein’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks begin to appear. Physicists have identified a gap Einstein never had the tools ...

The universe has delivered the loudest gravitational wave ever recorded, and it appears to have given Einstein’s theory of general relativity one of i.

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

The decline of reading and the rise of social media are again transforming what it feels like to be a thinking person.

A century after Erwin Schrödinger sketched out a bold vision for how we perceive color, scientists have finally filled in the missing pieces. A Los Alamos team used advanced geometry to show that hue, ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

Theoretical research led by Professor Enrique Gaztañaga of the University of Portsmouth challenges the ...
