For many years, astronomers have relied on distant supernovae as cosmic beacons to study the universe and test the laws of physics. But while analyzing one particular stellar explosion, Joseph Farah, ...

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 ...

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 ...

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 ...

ABSTRACT: The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field is applied to spiral and dwarf galaxy rotation curves. A new ...

Understand Einstein’s General Relativity with a clear and easy-to-follow explanation that breaks down complex ideas like spacetime, gravity, and curvature in simple terms. This video uses intuitive ...
