The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...

On January 14, 2025, the Laser Interferometer Gravitational-wave Observatories (LIGOs) recorded a cosmic tremor unlike any before. Named GW250114, the signal was the ‘loudest’ gravitational wave ...

This year, ASC26 has attracted more than 300 student teams from universities and colleges across Chinese mainland, the United States, Germany, the United Kingdom, Singapore, Colombia, Brazil, ...

A team of physicists led by Jared Fuchs at the University of Alabama in Huntsville has produced a peer-reviewed warp drive ...

A cluster of recent theoretical papers has laid out mathematical frameworks for propelling spacecraft at speeds ranging from ...

When students learn that Albert Einstein won a Nobel Prize, the assumption feels automatic: relativity. The bending of space and time. The theory that redefined gravity and reshaped modern physics.

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth. Of the more ...

I’ve yet to meet a physicist that didn’t believe in the beauty of the general theory of relativity—Einstein’s description of gravity as the curvature of spacetime. After all, it’s consistently ...

CAPE CANAVERAL SPACE FORCE STATION — Despite the number of struggles Relativity Space has faced trying to get the world’s first 3D-printed rocket off the ground, it finally succeeded Wednesday night, ...

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...
