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...

Astronomers Observe Black Hole Twisting Spacetime for the First Time, Confirming Einstein’s Theory
Astronomers have directly observed a black hole twisting spacetime for the first time, confirming Einstein’s long-standing prediction. The effect was detected during a violent stellar destruction event, where repeating X-ray and radio signals revealed a slow cosmic wobble. The discovery provides new insight into black hole spin, jets, and extreme...

Clocks on Mars Run Faster Than on Earth, New Study Finds
New research shows time on Mars runs faster than on Earth by 477 microseconds per day. The variation poses challenges for astronauts, navigation, and creating interplanetary communication networks. Scientists say understanding Martian time differences is key for future missions and testing Einstein’s relativity.

Rare ‘Second-Generation’ Black Holes Detected, Proving Einstein Right Again
Scientists have detected two unusual black hole mergers showing signs of “second-generation” origins — meaning each large black hole likely formed from an earlier merger. The gravitational-wave signals also matched Einstein’s predictions on spinning black holes, offering fresh proof of general relativity and new insights into how black hole...

Bangladesh Bars Ex-PM Sheikh Hasina, Family From Voting In Next Year Poll
Bangladesh's Election Commission (EC) on Wednesday said it has "locked" the national identity cards of deposed prime minister Sheikh Hasina, effectively barring her from voting in the general elections scheduled for February next year.

Delhi Records Season's Lowest Temperature At 26 Degree Celsius Today
Delhi on Wednesday recorded a minimum temperature of 26.1 degrees Celsius, 0.8 degrees below the normal, and the lowest of the season, the Met office said.

Gravitational Waves Reveal Most Massive Black Hole Merger Ever Observed
The GW231123 event marks the most massive black hole merger ever detected through gravitational waves, involving black holes of 100 and 140 solar masses. Observed by the LIGO-Virgo-KAGRA network, it challenges current black hole formation models with extreme mass and spin, suggesting a complex origin. Scientists believe its full implications may ta...

New Theory Challenges Black Hole Singularities, But Critics Raise Red Flags
A new black hole theory proposes a fix to the long-standing singularity paradox by modifying gravity equations. But scientists like Nikodem Poplawski argue that the model lacks observational support and rests on speculative assumptions. He suggests future data from gravitational waves or the cosmic microwave background may one day help us uncover t...

Where Is The Centre Of The Universe?
Published in 1915, and already widely accepted worldwide by physicists and mathematicians, the theory assumed the universe was static unchanging, unmoving and immutable.

James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus
A striking new image from the James Webb Space Telescope reveals an Einstein ring in the Hydrus constellation. The phenomenon occurs when a massive foreground galaxy bends light from a hidden background galaxy, forming a near-perfect ring. This effect, predicted by Einstein’s theory of general relativity, helps astronomers study galaxies from the...
