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.

The loudest collision ever recorded between two black holes has allowed scientists to test Einstein’s theory of general relativity in unprecedented detail, showing that the physicist’s predictions ...

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 ...

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, ...

[Translated by Dr. Robert W. Lawson.] THERE is something attractive in presenting the evolution of a sequence of ideas in as brief a form as possible, and yet with a completeness sufficient to ...

Exploring the quantum nature of gravity requires systems that balance quantum control and gravitational interaction, most plausibly within the microgram-to-milligram mass range. Here, the authors ...

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 ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking what happens when the observer is part of that world ...
