A new statistical model reveals more details about the ringdown period of merging black holes.

The LIGO–Virgo–KAGRA (LVK) detector network has a new trick up its sleeve to improve the instruments’ sensitivity to gravitational waves: it’s called Astrophysical Calibration and it plays a role similar to auto-tune in music production.

Researchers at the University of Alabama in Huntsville have found a new way to measure the mass of neighbouring galaxies using pulsars. Using the universe's most precise natural clocks it’s possible to detect tiny gravitational disturbances rippling…

New theoretical work suggests that the pattern of light emitted by atoms could be used to detect gravitational waves at frequencies outside the range of traditional detectors

Dark matter makes up roughly 85 percent of all the matter in the universe. We have never directly detected a single particle of it. But a new method developed by physicists at MIT and across Europe may have just opened a door we didn't know existed.…

From Independent RSS Feed: Scientists might have finally found a way to spot dark matter

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated…

"The key question now is, are these black holes telling us that our models of stellar evolution are wrong, or are they being made in another way?"

Newton's gravitational constant, G, is still known to just 3 significant figures in 2026. New measurements merely highlight our uncertainty.

I want to put a framework in front of people who know this field better than anyone and ask for honest criticism. The Mycelium Paradigm proposes three things working together: **On receiving:** A dedicated mission to the Solar Gravitational Focal Point at…

A new Space Warps project lets the public hunt for gravitational lenses in data from the Euclid Space Telescope.

When the gravity of a foreground object distorts and magnifies light from the background, the images surround the object responsible for the lensing.

Einstein told us that massive objects bend light and he was of course, right. Across the universe, giant galaxies are acting as natural telescopes, warping and distorting the light of objects behind them into spectacular arcs and rings.…

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself.…
