"The Most Important Satellite Youve (Probably) Never Heard Of Remove your personal information from the web at https://joindeleteme.com/SPACETIME One of the most important reasons we go to space is to know our own planet better. Today I'm going to tell you about an orbiting facility that literally watches Earth's biosphere breath and grow and die with incredible resolution. I'll talk about its profound existential and economic importance and about why it's in danger of being lost. PBS Member Stations rely on viewers like you.

"How Quantum Entanglement Creates Entropy Sign Up on Patreon to get access to the Space Time Discord https://www.patreon.com/pbsspacetime Entropy is surely one of the most perplexing concepts in physics. Its variously described as a measure of a systems disorder - or as the amount of useful work that you can get from it - or as the information hidden by the system. Despite the seeming ambiguity in its definition many physicists hold entropy to be behind one of the most fundamental laws of physics.
