A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

For a long time, scientists knew of a “gravity hole” beneath Antarctica—an area with particularly weak gravitational force. Considering the various threats currently faced by the region, scientists ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

Gravity feels reliable—stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over Earth's surface. And it is weakest ...

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 ...

Sending a mission to the solar gravitational lens (SGL) is the most effective way of actually directly imaging a potentially ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

Einstein's general relativity predicted gravitational waves generated by massive object collisions, propagating at the speed of light and carrying information about their origin. Computational ...

The Sun would be a far more powerful telescope than any humanity could create in the near future. But to use it, we need to get to 650 AU.

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...
