Dark-energy evidence suggests the universe will end in a “big crunch” roughly 20 billion years from now. The universe is nearing the halfway point of what may be a 33-billion-year lifespan, according ...

Dark energy is one of the most mysterious concepts in all of the cosmos. We know very little about what it is but it just might play an overwhelming role in the death of the universe. Often referred ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an invisible force called dark energy. But new data suggest that this is ...

According to the equations that govern black holes, the larger one of these cosmic behemoths is the lower its average density – given that the universe contains a lot of relatively empty space, could ...

Here’s what you’ll learn when you read this story: A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain. The universe's ...

It will be a view unlike any other — completely invisible, exceptionally quiet and utterly transformative. Deep in the first moments of the Big Bang, the entire cosmos shook and rumbled. Those quakes ...

No one can say with scientific confidence why we exist or what happens when we die. In fact, scientists have a tenuous grasp ...

The universe's first magnetic fields may have been much weaker than we first imagined — and were roughly equivalent to the strength of the magnetic activity within the human brain, according to a new ...
