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 ...

How did the universe begin? A compact NASA space telescope that uses less power than a refrigerator is poised to chip away at that very large question. Called SPHEREx, and set for launch on a SpaceX ...

For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of ...

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 ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

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 ...
