For centuries, humanity has pondered the ultimate fate of the universe. From theories of infinite expansion to the concept of a cosmic “big crunch,” scientists have long sought to understand how the ...

A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.

The universe is expanding faster and faster, but not all scientists agree that dark energy is the cause. Perhaps, instead, our universe keeps colliding with and absorbing smaller 'baby universes,' a ...

Our universe could be dying much faster than scientists thought, but it's still going to be around for a mind-bogglingly long time, a new study finds. Researchers have proposed an updated theoretical ...

A radical hypothesis suggesting black holes could be behind the accelerating expansion of our universe has been stirring up controversy among astronomers. A new study may contain the first tantalizing ...

An international group of more than 900 researchers studying the expansion of the universe presented their findings on Wednesday during the American Physical Society’s Global Physics Summit in Anaheim ...

New observations from the James Webb Space Telescope suggest that a new feature in the universe -- not a flaw in telescope measurements -- may be behind the decade-long mystery of why the universe is ...

People predicting the end of world generally make those predictions without scientific evidence to support them. So when an animal-behavior researcher ran experiments in the 1960s that described ...

The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this. A study, published ...

How will the world end? While some, like Robert Frost, have waxed poetic about the end of life on Earth—fire or ice—others have been looking to science to solve the mystery. Even still, others have ...

The secrets of black holes and dark matter could lie before the Big Bang, a new study of "bouncing" cosmology hints. When you purchase through links on our site, we may earn an affiliate commission.
