Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be the interior of a black hole that formed in some larger cosmos. The notion ...

Add Yahoo as a preferred source to see more of our stories on Google. Parallels in the physics of the universe and that of black holes have led some cosmologists to wonder if our universe could have ...

New images of the infant universe captured by the Atacama Cosmology Telescope (ACT) are the most precise "baby pictures" to date of the cosmos' "first steps" toward forming the first stars and ...

The question of whether the cosmos goes on forever is no longer just a late night thought experiment, it is a live research problem that cuts to the heart of modern physics. Astrophysicists are using ...

Weeks after his death, physicist Stephen Hawking has delivered his last thoughts about the nature of the cosmos, and he says it may be simpler than often believed. Well, simpler if you understand ...

Positive curvature, like that on a sphere, implies a finite universe, while zero curvature, as on a flat plane or negative ...

WASHINGTON — Using data from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the ...

American Museum of Natural History Astronomer Dr. Jackie Faherty joins WIRED to answer the internet's burning questions about ...

Sometimes, a picture can be worth much more than a thousand words. For instance, one measure associated with the pictures below—new high-definition snapshots of the cosmos in its infancy—is 1,900 ...

Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had ...
