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 ...

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 ...

For years, the James Webb Space Telescope has been finding surprises in the early cosmos. Now it has once again pushed the boundary of the observable universe.

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 ...
