For a generation, cosmologists have worked with a simple story: the universe is not only expanding, it is expanding faster ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. Subscribe to our newsletter for the latest ...

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 ...
