In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

While measurements from the Planck satellite, which studied the early Universe, indicated a certain expansion rate. A new study led by Dan Scolnic from Duke University suggests that the Universe is ...

DURHAM, N.C. — Our cosmic neighborhood is revealing an uncomfortable and unexplainable truth: the universe seems to be breaking the speed limit set by our best physics models. By precisely measuring ...

The universe really seems to be expanding fast. Too fast, even. A new measurement confirms what previous—and highly debated—results had shown: The universe is expanding faster than predicted ...

100 years ago, Hubble revealed a universe of galaxies that existed beyond ours — but he couldn't have done it without a little help. If we could go back 101 years, we would encounter a time when ...

The expansion rate of the Universe has befuddled and concerned researchers for decades. Recent measurements have only added to the mystery and heightened the alarm within the scientific community, ...

For example, we do now know that habitable environments are very common in the universe. It is reasonable to generalize from here to a truly gargantuan number of habitable environments across the ...

A Yale-led team of astronomers has detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The ...
