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

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 ...

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

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

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 ...

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.

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

Astronomers have uncovered what may be the most massive black hole ever found, 36 billion times the mass of our Sun, hidden at the heart of the Cosmic Horseshoe galaxy. Located 5 billion light-years ...

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, ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...
