— The universe had a secret life before the Big Bang, new study hints But as the universe's expansion slows down, the density of holographic dark energy dwindles along with it.

Their conclusion: not only was the universe expanding, but that expansion was accelerating. “People did not expect that,” says Adam Riess of Johns Hopkins University, who shared a Nobel prize ...

“In my work, I propose another model to explain the present accelerated expansion of the universe. Unlike existing models, this does not require any form of dark energy or modified gravity ...

But thanks to the new James Webb Space Telescope, scientists from the University of Chicago have been able to take new and better data—suggesting there may be no conflict after all. “This new evidence ...

The model is based on a solution to Einstein’s general theory of relativity (our best understanding of gravity) that assumes the universe is homogeneous and isotropic on large scales – meaning ...

The standard model explains the evolution of galaxies, cosmic microwave background from the big bang, the abundances of chemical elements in the universe, and many other key observations based on ...

The current model of universe expansion is complicated by “Hubble tension,” an anomaly in which evidence from the afterglow of the Big Bang (known as the Cosmic Microwave Background) shows that the ...

The standard model of cosmology is the conventional wisdom about the underlying physics of the universe. Often called the Lambda-CDM theory, this suggests the universe has three major components ...

For decades, scientists assumed that the expansion of the universe was powered by a new entity, known as the inflaton, but new research suggests that it may have been possible without it.

The chances of intelligent life emerging in our Universe -- and in any hypothetical ones beyond it -- can be estimated by a new theoretical model which has echoes of the famous Drake Equation ...
