By mapping the distribution of galaxies, researchers have shown that Einstein’s model of gravity still holds true even when applied over billions of years of cosmic history. Leading the analysis ...

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

The search for alien life has long been focused on detecting signals from distant civilizations, primarily through ...

General relativity has passed one of its most precise tests ever thanks to observations of the past 11 billion years of cosmic evolution collected by the Dark Energy Spectroscopic Instrument, or DESI.

Throughout the universe, every scrap of matter would be exerting its exquisitely predictable influence on the man, through gravity. This was Einstein’s key insight—that acceleration and ...

Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

A stunning new image from the James Webb Space Telescope reveals a cosmic mirage known as an Einstein ring, where the light ...

a nearly perfect Einstein ring, formed by the warped light of a distant galaxy curved by the intense gravity of another. Released as the European Space Agency’s March 2025 image of the month ...
