The Big Bang is often presented as if science has completely solved the beginning of the universe: everything started in one ...

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 ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Credit: Christine Daniloff / MIT / ESA / Hubble / NASA Many ...

Initially starting as a solution to the problem of flatness in the early universe, cosmic inflation has become a central idea in modern cosmology. The key to its power comes from how well it can ...

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 ...

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 ...

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 ...
