“The new data seem to indicate that the cosmological constant is negative, and that the universe will end in a Big Crunch,” states Henry Tye, Horace White Professor of Physics Emeritus at Cornell.

“Under the right conditions, this collapse doesn’t end in a singularity — instead, it bounces and begins expanding again,” said University of Portsmouth professor Enrique Gaztañaga in a statement that ...

When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact ...

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 ...

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 ...
