General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

Astronomers have identified the birth of a magnetar, a hyper-magnetized neutron star, by detecting a subtle warping of ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist Dan Kasen. Kasen and his colleagues hypothesized that at least some ...

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate student at UC Santa Barbara ...
