Albert Einstein is famous for his contributions to physics, even predicting this strange and fascinating gravitational effect ...

An international team, spearheaded by Prof. Luciano Rezzolla at the Goethe-Universität, has invented a novel approach to ...

If true, it could mean the universe is destined to collapse rather than expand forever. Einstein proposed the cosmological ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

Twin black hole collisions detected in 2024 have provided the sharpest-ever test of Einstein’s theory while revealing new details about how black holes form and spin.

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the driving force behind creation. Their simulations show that gravity and ...

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

As telescopes peer into the universe, they sometimes see quirks of nature that magnify faraway objects. These eight galaxies recently imaged by the James Webb Space Telescope (JWST) appear stretched, ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.
