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 ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth. Of the more ...

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 ...

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame. Planets with two suns have long captured the imagination of science ...

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

A good scientific theory is one that allows us to calculate the results of many observations from few assumptions.” — Physicist Sabine Hossenfelder Hossenfelder’s concise statement explains why the ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

February is a highly anticipated month as the Indian government tables the Union Budget in Parliament. This year marks the 90th anniversary of a book whose ideas broadly lays the economic foundations ...
