A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize the cosmological constant in ways previously unrecognized.

The conclusion of DESI's first survey marks an important milestone for cosmology, which finds itself in a bind for the best ...

Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

If you understand how things work,” she says, “you can do things with that knowledge.” But she’s in this to solve an ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

Prof Stephen Hawking’s closest collaborator explains emerging evidence supporting the cosmologist’s final thoughts on time ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

The most precise measurement yet of how fast the Universe is expanding shows we have a real and serious problem on our hands.

A new JCAP study tests an “emulator” to reconstruct the large-scale structure of the cosmos If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a ...
