In a cavernous tunnel beneath the French–Swiss border, physicists have briefly recreated conditions that existed microseconds ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

Dark matter, the invisible substance that shapes the Universe, may have had a far more dramatic beginning than scientists once believed.

For decades, scientists have viewed the Big Bang as the starting point of space and time. But research into cosmic inflation—the lightning-fast expansion that likely occurred before the Big Bang ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

The Big Bang Theory has finally come to an end, and it left all of the characters at a good place. The episode revolved around Sheldon and Amy receiving the Nobel Prize for Physics, but the final shot ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our ...

Was the Big Bang really the beginning of the universe, or are we 'bouncing' between periods of expansion and contraction? A new theory makes testable predictions. When you purchase through links on ...
