This video explores the connection between Cosmic Inflation at the Big Bang and Dark Energy, examining how these concepts ...

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 ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model. It explains why ...

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 ...

Satellites come in all shapes and sizes, but there aren’t any that look quite like SPHEREx, an infrared observatory NASA launched Tuesday night in search of answers to simmering questions about 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 ...
