The Universe might not exist forever. New observations by physicists indicate that it will one day reach its maximum size before beginning to contract. These results profoundly change our view ...

Unraveling the mysteries of how the world might end is fascinating and terrifying. It's a topic that sparks our imagination, ...

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 ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

The Universe may not have begun with a Big Bang, but instead with a Big Bounce, according to a new theory about how the Universe expands ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

The universe is poised to die much faster than previously thought, according to new research by Dutch scientists. But there's no great need to panic. We still have 10 to the power of 78 years before ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a ...

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, ...

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 ...

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy. Dark Energy Spectroscopic Instrument (DESI) collects data ...
