By comparing it to observations of the very early universe and supernovae, they have been able to suggest that dark ...

New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, ...

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama ...

In short, this would mean the cosmological constant does not explain dark energy. In 1988, the 2019 physics Nobel laureate P. J. E. Peebles wrote a paper with Bharat Ratra on the possibility that ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...

First discovered in the 1990s, dark energy has come to feel like a familiar face of the cosmos. Astronomers first imagined ...

If dark energy is weakening, it stands to reason that eventually gravity will become dominant and the universe will begin to contract. In such a scenario, the universe would collapse back into a ...

U.S. National Laboratories (Argonne, Lawrence Livermore, and Oak Ridge) possess three of the world’s fastest exascale ...

In short, this would mean the cosmological constant does not explain dark energy. In 1988, the 2019 physics Nobel laureate P. J. E. Peebles wrote a paper with Bharat Ratra on the possibility that ...

By comparing it to observations of the very early universe and supernovae, they have been able to suggest that dark energy—the mysterious force propelling our universe’s expansion—is not constant ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

In short, this would mean the cosmological constant does not explain dark energy. The Big Crunch In 1988, the 2019 physics Nobel laureate P. J. E. Peebles wrote a paper with Bharat Ratra on the ...
