The Earth might be near the center of a vast low-density void in space, which could explain one of the cosmos's greatest ...

Are we living in a cosmic void? New theory suggests our galaxy sits in a giant hole warping the universe's expansion.

There are new hints that the fabric of space-time may be made of "memory cells" that record the whole history of the universe. If true, it could explain the nature of dark matter and much more ...

Astronomers claim to have found new evidence supporting a controversial observation that our galaxy is residing in an unusually sparse region in space. If it's correct, it could rewrite cosmology.

According to a provocative new study, that might just be our cosmic address. This idea is meant to solve one of the biggest ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the ...

Cosmology Universe may revolve once every 500 billion years — and that could solve a problem that threatened to break cosmology. Cosmology Gamma-ray bursts reveal largest structure in the ...

He is a member of the National Science Foundation-funded Atacama Cosmology Telescope collaboration, an international group of more than 160 members who developed the map.

Is cosmology in crisis? A potent mix of hard-won data and rarefied abstract mathematical physics, the standard model of cosmology is rightfully understood as a triumph of human ingenuity.

This could lead to a major paradigm shift in cosmology, akin to the discovery of the accelerated expansion of the universe in the late 1990s. But on this path we may have to reckon, ...
