Study Finds Potential Dark 'Matter Imprint' In Gravitational Waves
Scientists emphasised that more observations and analysis are required before any confirmed detection of dark matter can be claimed.

Study Reveals Black Hole Collisions May Be Creating Universe's Biggest Cosmic Giants
According to the study, this creates a forbidden mass range for stellar-mass black holes formed from collapsing stars.

Largest Black Holes May Form Through Repeated Collisions, Study Suggests
New gravitational-wave data from LIGO Scientific Collaboration, Virgo, and KAGRA suggests the largest Black Holes form through repeated mergers inside dense star clusters rather than directly from collapsing stars.

New Gravity Theory Challenges Big Bang Singularity Problem
A new theory called Quadratic Quantum Gravity extends General Relativity to extreme energies, removing the Big Bang singularity and predicting testable gravitational wave signals from the early universe.

New Study Claims There Might Be Way More Pulsars in Space Than We Previously Thought
Astronomers have discovered that fast-spinning pulsars emit radio waves far beyond their magnetic poles, reaching the edges of their magnetic fields. The finding challenges long-held theories and could help scientists discover more pulsars and improve gravitational wave detection.

Hubble Constant Puzzle Deepens as Supernova and CMB Measurements Clash
Astronomers are testing a new way to measure the universe’s expansion rate using the gravitational-wave background detected by NANOGrav. By treating the cosmic hum from merging supermassive black holes as a statistical “stochastic siren,” researchers hope to calculate the Hubble constant and help resolve the long-standing Hubble tension betwe...

Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping
Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

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...

LIGO Detect Possible Second-Generation Black Holes with Extreme Spins
LIGO-Virgo-KAGRA observatories detected two extraordinary black hole collisions in late 2024—GW241011 and GW241110. The first involved a rapidly spinning black hole, while the second revealed one rotating opposite its orbit. These findings fit predictions for second-generation black holes, born from earlier mergers within crowded star clusters. T...

Pulsar Observations Could Reveal Gravitational Wave Interference From Black Holes
A new study proposes detecting gravitational-wave “beats” using pulsar timing. Researchers from Hirosaki University suggest that interference between waves from supermassive black hole binaries could appear as periodic variations in pulsar signals. The method may help distinguish individual sources from a diffuse gravitational-wave background i...

Astronomers Capture First Image of Two Supermassive Black Holes Orbiting Each Other
Astronomers have captured the first image of two supermassive black holes orbiting in quasar OJ 287. The smaller black hole’s jet spirals due to gravitational forces from the larger one. This discovery validates dual-core theories and opens doors for research on gravitational waves and galaxy evolution.

Black Hole Kicked Away? Gravitational Waves Reveal Einstein’s Ripples in Spacetime
Astronomers have, for the first time, measured the recoil speed and direction of a newborn black hole using gravitational waves. Data from the 2019 event GW190412 revealed the remnant shot away at 50 km/s. This breakthrough shows gravitational waves can reconstruct full 3D motion, offering new ways to connect black hole mergers with light signals.

Twisted Jet Confirms Most Extreme Binary Black Hole System in the Universe
Astronomers have confirmed that the blazar OJ 287 hosts the most extreme binary black hole system ever found. Using a global radio telescope array, they captured an ultra-sharp image showing a dramatically bent jet—evidence of two supermassive black holes locked in orbit. The system’s 12-year flare cycle and jet twists match predictions of a sm...

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...
