Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

Scientists may have identified the gravitational waves that make up some of the universe’s background, not just those coming from unusual events like black hole collisions. New Atlas reports that the ...

Even when you remove the bright stars, the glowing dust and other nearby points of light from the inky, dark sky, a background glow remains. That glow comes from the cosmic sea of distant galaxies, ...

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown.

Astronomers are trying to listen to the universe's background hum — a cascade of gravitational waves believed to exist since the first rapid inflation of space following the Big Bang over 13.8 billion ...

A new study has estimated the universe’s possible age by using precise data on stars.

Astronomers across the world announced on Thursday that they have found the first evidence of a long-theorised form of gravitational waves that create a "background hum" rumbling throughout the ...
