Let's talk about astrophysics, cosmology and how our universe works. In this episode of Crash Course Physics, Shini sits down to talk about Astrophysics and Cosmology. By using what we've learned this ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

A theory that unites quantum mechanics and general relativity claims that there was no first moment in time, but it still agrees with the predictions of classical cosmology. It's in the stars One of ...

The 2019 Nobel Prize in Physics goes to James Peebles “for theoretical discoveries in physical cosmology” and to Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type ...

Stuart Clark's new book sweeps over you like a maelstrom of names, places and ideas. In The Unknown Universe, Clark sets out to describe the state of our knowledge — and lack thereof — about central ...

Around 300 years ago Isaac Newton showed that the same laws governed the fall of an apple and the movement of the planets, and he changed how we see the world. Around a hundred years ago, Albert ...

A six-year-old controversial theory that told of a time before the Big Bang is undergoing a resurgence, only to be lampooned again by its original critics. The theory of ekpyrotic cosmology was first ...

Michael Boylan-Kolchin and others show “early dark energy” might help solve the Hubble Tension and explain why there are more early galaxies than expected. A panel of physicists and astronomers ...

THIS YEAR’S Nobel prize for physics was split two ways, but both halves went for discoveries beyond Earth. One was for a finding that is, by astronomical standards, quite close by—a planet going ...
