Is Earth the only living needle in this haystack of planets?

Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub

Are there exoplanets like Earth? We live in one of a hundred billion of galaxies, each with hundreds of billions of stars. And now, thanks to modern astronomy, we know that the Milky Way is home to perhaps a hundred billion planets! In the past two decades, these exoplanet discoveries have spawned new questions about our universe, and if there might be another Earth, or other life, somewhere out there.

In part 1 of our two-part series on exoplanets, we'll look at how astronomers find exoplanets, and what it means to call them Earth-like. We'll trace the history of planetary science back three thousand years and examine Earth's changing status in the cosmos. We were once the center of the universe, and now Earth is just another rock in the sky. What does that mean for us?

The Map of Particle Physics | The Standard Model Explained Teacherflix 28 Ansichten • 8 Monate vor

In this video I explain all the basics of particle physics and the standard model of particle physics. Check out Brilliant here: https://brilliant.org/DOS/
Buy the poster here: https://store.dftba.com/collec....tions/domain-of-scie

The standard model of particle physics is our fundamental description of the stuff in the universe. It doesn’t answer why anything exists, but does describe what exists and how it behaves, and that’s what we’ll be discovering in this video. We will cover the fermions, which contain the quarks and the leptons, as well as the bosons or force carriers. As well as which of the fundamental forces each of these fundamental particles interact with, along with the Higgs field. We’ll also look at the conservation rules of particle physics, symmetries in physics and the various quantum numbers that rule which particle interactions are valid and which are not.
