This Is The Hardest Concept To Understand In Physics... Yet It's The Most Important

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/1Nm0Qc8... Cross every other number off an endless list, then ask what is left — fewer than you began with, or somehow exactly as many? That harmless little question is where a quiet, century-long unraveling begins. How large, really, is the infinity hiding in the ruler on your desk? Tonight we follow one stubborn, brilliant mind from a simple counting puzzle out to the far edge of what mathematics itself is able to decide, one slow and patient step at a time. Where does the understanding finally run out? Get comfortable, dim the lights, and let this long, gentle walk through the sizes of infinity keep you company tonight.
