The question of what existed before the Big Bang has baffled scientists for years. While theBig Bang is thought to have ...

A project to map galaxies across the universe may have spied cracks in the foundation of our understanding of the cosmos.

New observations with the Atacama Cosmology Telescope in Chile reveal the earliest-ever "baby pictures" of our universe, ...

Cosmologists are using cutting-edge computational tools to uncover the secrets of dark matter and dark energy, which together ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent). Scientists have ...

Tyas The universe is a strange place: just 5% of the mass of everything that exists is made up of regular matter. The rest is made up of 25% dark matter and 70% dark energy. Dark matter is already ...

"We are able to measure the local dark matter density using direct acceleration measurements for the first time." Dark matter, widely known as the universe's most mysterious stuff, is rarer on ...

The first dark matter search using the WINERED spectrograph on a large telescope in Chile has set new constraints on the lifetime of dark matter particles with masses between 1.8 and 2.7 eV.

"Most of them are solitary. In this new work, we show how to effectively double the number of pulsars we can use to constrain dark matter in the galaxy by rigorously using solitary pulsars to ...
