“Dark energy,” a mysterious force that counters gravity, has been proposed to explain why the universe is expanding at an accelerating rate. Mathematicians at UC Davis and the University ...
The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make up nearly 70% of the cosmos, has been the leading explanation. But a new ...
Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help ...

New York University physicist Georgi Dvali concludes that the cosmic acceleration of the universe may be caused by the modification of standard laws of gravity at very large distances, and not by " ...
On April 30, two major observatories reported breakthroughs in understanding extreme cosmic particle acceleration. China's LHAASO detected ultra-high-energy gamma rays from a binary star system, while ...
If it’s possible to make a mystery more mysterious, then a study of dark energy by astronomer Bradley Schaefer of Louisiana State University in Baton Rouge may have done so. Earlier this month, at the ...
This time ten years ago, two independent teams of researchers in the US were deliberating over whether to go public with a discovery that would change our view of the universe forever. It concerned ...
In all directions of the sky, cosmic rays rocket through space with incredible speed. These "rays"—which mostly consist of protons—are some of the most energetic particles in the universe. For nearly ...
