We live in a golden age for learning about the universe. Our most powerful telescopes have revealed that the cosmos is surprisingly simple on the largest visible scales. Likewise, our most powerful ...

Add Yahoo as a preferred source to see more of our stories on Google. Before there was light, there was cosmic inflation. Before life, planet Earth, the first galaxies — and even before the violent ...

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

In this video, we explore the Big Bang theory and common misconceptions surrounding it. The Big Bang theory suggests an explosion from an infinite density point, which is incorrect; instead, it ...

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 ...

Cosmic inflation posits a brief epoch of accelerated expansion in the early Universe, resolving the horizon and flatness puzzles while laying down the primordial density fluctuations that seed cosmic ...

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

An apparent shift in the value of an important inflation parameter may be an artifact of differences between cosmological datasets. Ferreira and her colleagues compared BAO information indirectly ...

Before there was light, there was cosmic inflation. Before life, planet Earth, the first galaxies—and even before the violent explosion of hot dense primordial stuff scientists have traditionally ...
