Cyclic cosmology, or the big bounce, is the idea that the universe will eventually crunch back together and then go through ...
Gravity has been tested extremely well inside the solar system. On cosmic scales, direct tests are harder. This study pushes ...

Study proposes pre–Big Bang black holes as a dark matter source
What if the mysterious substance holding galaxies together is made of leftovers from a universe that existed before our own? That is the central question posed by physicists Carlo Rovelli and ...
Physicists have used the Atacama Cosmology Telescope to prove that gravity follows the rules of Newton and Einstein across ...
Cosmological expansion is widely treated as a proven fact. It is not proven. For nearly a century, cosmology has told a ...
Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and ...
Scientists have tested gravity across some of the largest structures in the universe and found that it behaves exactly as ...
The Dark Energy Spectroscopic Instrument (DESI) has completed its five-year mission to build the largest 3D map of the cosmos ...
New research suggests that relic black holes from before the big bang may still shape galaxies today. These black holes could ...
Black holes that formed before the Big Bang could still exist today as ‘cosmic fossils’, potentially helping to explain the ...
A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.
