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 ...

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest. Based on several recent dark energy ...

Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the ...

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 fact is, however, that the mass of black holes varies greatly out in the vast universe, and astronomers have recently discovered what they believe may be the biggest one ever found. They estimate ...

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 ...

"Challenging long-held assumptions is essential to scientific progress." A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

"Theories involving substantial formation of stars prior to or together with the black hole formation and growth are very unlikely." Using the James Webb Space Telescope (JWST), astronomers observing ...
