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 ...

Humanity has achieved remarkable milestones, including landing on the Moon and photographing black holes, yet approximately 95% of the universe remains a mystery. Current theories like general ...

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 ...

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 ...

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 ...

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 ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

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 ...
