Two Black Holes With Unusual Behaviour Disrupt Traditional Theories About Their Formation
Astronomers are observing two unique black holes defying established cosmic theories. One, known as the "serial killer" black hole, is preparing to consume its second star in five years, an event that rarely occurs within such a timeframe. The other black hole, part of a triple system called V404 Cygni, has a structure that defies traditional black...

Study Claims Black Holes Could be Driving Universe's Expansion
A new study proposes that black holes could hold the key to dark energy, which fuels the accelerating expansion of the universe. Using the Dark Energy Spectroscopic Instrument (DESI), astronomers observed a possible correlation between the growth of black holes and an increase in dark energy. The study's co-authors, Gregory Tarlé and Duncan Farrah...

Astronomers Discover Rare Triple Black Hole System in Milky Way, Challenging Formation Theories
Astronomers has revealed a rare triple system in the Milky Way consisting of a black hole and two stars, known as V404 Cygni. Located approximately 8,000 light-years away, this system poses new questions about black hole formation, suggesting that they may arise through a less violent "direct collapse" process rather than the expected explosive eve...

JWST Spots Isolated Supermassive Black Hole-Powered Quasars in the Early Universe
A team using the James Webb Space Telescope has discovered supermassive black hole-powered quasars in unexpectedly isolated environments. These lonely quasars, some of the earliest in the universe, present a mystery as they lack the dense surroundings that current theories suggest are needed for black hole growth. This discovery is pushing scientis...

New Research Could Resolve Stephen Hawking's Black Hole Radiation Paradox
Recent research indicates that black holes may actually be “frozen stars,” complex quantum objects that lack the typical singularities and event horizons of conventional black holes. This theory, led by physicist Ramy Brustein from Ben-Gurion University, aims to resolve Stephen Hawking's famous radiation paradox, which suggests information is l...

Mars’ Orbit Wobble Could Hint at the Presence of Dark Matter Emitting from Primordial Black Holes
MIT physicists have proposed that Mars' orbit might wobble due to the presence of primordial black holes, which could be a major source of dark matter in the universe. This theory builds on the idea that such black holes, formed just after the Big Bang, pass through our solar system and cause a gravitational effect detectable by current technology....

NASA James Webb Space Telescope Unearths Oversupply of UV Light from Early Stars and Black Holes
NASA’s James Webb Space Telescope (JWST) has revealed surprising new details about the universe's reionization process. The telescope has found an unexpected oversupply of ultraviolet (UV) light emitted by early stars and giant black holes, contradicting previous theories. This discovery suggests a more complex reionization process, potentially d...

James Webb Space Telescope Uncovers Surprising Dust Formation Near Supermassive Black Hole
James Webb Space Telescope images have uncovered an unexpected dust formation around a supermassive black hole, showing that gas collisions, not black hole radiation, heat the dust. This breakthrough by Newcastle University’s team challenges existing theories and offers new perspectives on galaxy evolution.

Matter Falls Into Black Hole But Where Does It Go? Scientists Use Einstein's Theory To Find Out
Oxford University scientists have confirmed a major prediction of Einstein's theory of gravity, providing the first observational evidence of a 'plunging region' around black holes.

Stephen Hawking's Famous Theory Could Mean That Entire Universe Is Doomed To Evaporate: Study
This radiation is also caused by gravity and the curvature of spacetime. This means that all large objects in the universe will eventually vanish.

How The 1st Image Of The Supermassive Black Hole At Milky Way's Centre Was Captured
Black holes are among the most profound predictions of Einstein's theory of general relativity. They were originally studied as a mere mathematical consequence of the theory rather than as physically relevant objects.

Space-Time Travel Through Wormholes Could Be a Possiblity, New Study States
There has been a lot of debate on whether space-time travel through wormholes is possible or not. Most studies have suggested these hypothetical shortcuts are not possible as any passage of a vehicle through one would instantly lead to its collapse. However, a new theory says space-time travel through wormholes may be possible after all.

Scientists Detect Light Being Ejected From Behind Black Hole, Proving Einstein's Theory Correct
Researchers have now been able to see light being ejected from behind a supermassive black hole, 800 million light-years away from Earth. These light waves — called "echoes" — were detected in the form of X-rays, according to a study published in the Nature journal.

Spectacular Gamma Radiation From Collapse Of Dying Star Could Change Understanding Of The Universe
Scientists have recorded a cosmic explosion of gamma radiation from a collapsing star that challenges the established theory of gamma-ray bursts. The scientists said that these explosions occur when a massive star abruptly detonates and turns into a black hole.

Dozens of Newly-Detected Gravitational-Wave Events May Help Better Understand Black Holes, Neutron Stars
Astrophysicists have found new 39 gravitational-wave events caused by collision of black holes and neutron stars far in the universe. These, along with previously observed 11 events, will help them understand the population of black holes and neutron stars across the universe.
