Researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences examined the validity of the theory of relativity with the highest…
JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that…
One of the major issues in general relativity that separates it from other descriptions of the universe, like quantum physics, is the existence of singularities….
Published in Nature Astronomy the work which shows the unprecedented accuracy with which gravitational wave observations by the space interferometer LISA will be able to…
Since Einstein formulated his theory of general relativity (GR), the geometric theory of gravity that fundamentally altered our view of the universe, more than a…
The theory of general relativity passes a range of precise tests set by pair of extreme stars. An international team of researchers from ten countries…
Researchers at the University of East Anglia and the University of Manchester have helped conduct a 16-year long experiment to challenge Einstein’s theory of general…
Researchers study cosmic expansion using methods from many-body physics. It is almost always assumed in cosmological calculations that there is an even distribution of matter…
Further confirmation of Einstein’s theory of general relativity. The galaxy Messier 87 (M87) is located 55 million light years away from Earth in the Virgo…
Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein’s…
For the first time, astronomers have singled out light coming from behind a black hole, enabling them to study the processes on its far side….
First Detection of Light From Behind a Black Hole Watching X-rays flung out into the universe by the supermassive black hole at the center of…
A Penn State scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of…
Scientists from the International Center for Radio Astronomy Research (ICRAR) and The University of Western Australia (UWA) have set a world record for the most…
It’s one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey…
This NASA/ESA Hubble Space Telescope image features the galaxy LRG-3-817, also known as SDSS J090122.37+181432.3. The galaxy, its image distorted by the effects of gravitational…
Final Dance of Unequal Black Hole Partners Rochester Institute of Technology scientists perform first-ever simulation of large mass ratio black hole merger on Frontera. Solving…
What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common? The answer is…
