How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

A new Utah Valley University study is providing new evidence in a debate astronomers across the world haven’t been able to agree on — how fast the universe is expanding. The findings may add more fuel ...

The cosmos is riddled with evidence that the universe began with an unfathomably rapid expansion — even faster than in traditional Big Bang theories — but scientists don’t know why it happened. A ...

One of the big mysteries of the universe is how it's expanding. The phenomenon causing that expansion is known as dark energy — and recently, scientists have started to wonder if its changing. Now let ...

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 purchase ...

The six-year Dark Energy Survey has released its full results, showing that two leading models of cosmology are equally valid ...

A two-year NASA mission is using research from a University of Arizona team to discover the origins of the Milky Way and the universe. SPHEREx, or Spectro-Photometer for the History of the Universe, ...

In the grand puzzle of the cosmos, one question continues to defy easy answers: how fast is the universe expanding? Astronomers have tried two main methods to figure it out, but their numbers don’t ...
