New Study Explores How LIGO-Style Lasers Could Test Quantum Gravity
Gravitational waves, first directly detected in 2015, have opened a new way of observing the universe. Now, physicist Ralf Schützhold of HZDR proposes going a step further—actively interacting with these ripples in spacetime using powerful lasers. His theoretical scheme builds on LIGO-style interferometers, where intense laser pulses bounce repe...

Russia Patents Rotating Space Station Concept to Generate Artificial Gravity in Orbit
Russia’s Energia rocket company has patented a rotating space station concept designed to generate artificial gravity for astronauts. The system would use spinning habitable modules to simulate half of Earth’s gravity, potentially reducing health risks linked to long missions as the International Space Station nears retirement.

Astronomers Observe Star’s Wobbling Orbit, Confirming Einstein’s Frame-Dragging
Astronomers have detected a remarkable wobble in the orbit of a star being torn apart by a black hole, offering one of the clearest confirmations yet of Einstein’s frame-dragging effect. By tracking repeating X-ray and radio signals every 20 days, researchers captured spacetime twisting around a rapidly spinning black hole—revealing powerful in...

NASA’s GRACE Satellites Reveal Hidden Deep-Earth Process Behind Gravity Disturbance
Scientists have discovered a mysterious gravity signal detected by satellites nearly 20 years ago, which is linked to deep mantle changes beneath the Earth’s surface. The anomaly, lasting two years, coincided with a magnetic “jerk”, suggesting a rapid mass shift near the planet’s core.

New Black Hole Merger Gives Clearest Test of Einstein’s Relativity
LIGO has detected GW250114, the loudest gravitational-wave signal yet, marking ten years since its first breakthrough. The event confirmed Einstein’s relativity, Hawking’s horizon theorem, and Kerr’s spinning black hole model. By capturing the merger of two 32-solar-mass black holes, scientists gained the clearest view of black hole physics, ...

Scientists Apply Stephen Hawking's Theory to Propose Detectable ‘Black Hole Morsels’ in Space
A new study suggests “black hole morsels” — tiny, asteroid-sized black holes from cosmic mergers — could emit detectable bursts of Hawking radiation. Observatories like HESS, HAWC, and Fermi may already hold clues. Detecting them could unlock insights into quantum gravity, unknown particles, and even hidden dimensions beyond the Standard Mo...

US Has Likely Moved Nuclear Weapons In UK For First Time Since 2008: Report
The US has likely stationed nuclear weapons in the UK for the first time since 2008, in a signal to Russian President Vladimir Putin that it remains committed to European security.
