Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated ...

"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

For decades, astronomers have treated dark matter as the invisible scaffolding of the cosmos, a mysterious substance that ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new ...

According to new research dark matter is considered to be the most puzzling substance in the universe. It has been a thorn in the side of physicists; despite outweighing ordinary matter by a ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...
