A newly merged black hole does not become quiet at once. It vibrates, sheds energy through gravitational waves and produces a ...

Scientists analysed 168 gravitational-wave signals from colliding black holes and found no break from Einstein's theory of ...

As predicted by the theory of general relativity, the passage of gravitational waves can leave a measurable change in the relative positions of objects. This physical phenomenon, known as ...

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for ...

In a paper published in The Astrophysical Journal Letters, the international LIGO-Virgo-KAGRA Collaboration reports on the detection of two gravitational wave events in October and November of 2024 ...

Gravity from Entropy theory offers a new resolution to one of physics' oldest paradoxes: how the universe builds galaxies and ...

Deborah Ferguson (UT Austin), Bhavesh Khamesra (Georgia Tech), and Karan Jani (Vanderbilt University). After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of ...

Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things are left alone. So why is a new theory suggesting ...
