The long-standing problem of the cosmological constant, described both as “the worst prediction in the history of physics” and by Einstein as his “biggest blunder”, is being tackled with renewed ...

As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of ...

The original version of this story appeared in Quanta Magazine. Physicists have deduced subtle hints that the mysterious “dark” energy that drives the universe to expand faster and faster may be ...

Gamma-ray bursts (GRBs) are some of the most intense and energetic phenomena in the universe. Said to be the birth-cries of black holes, they’re just about the biggest bangs our universe has seen ...

What if outer space isn’t empty, but behaves like a thick, slow-moving fluid? Anew study suggests just that, and it could help solve a puzzling mismatch between current models of the universe and ...

Luz Ángela García is an astrophysicist who dreams of cracking the ultimate cosmological conundrum : why the universe is expanding at an accelerating rate. Currently a postdoctoral researcher at ...

Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely ...

A trio of physicists play with the math that describes Bose Einstein condensates. Hidden down behind the BEC's couch, they found a fake cosmological constant that they could use to show why our ...
