Was Penrose Right? New Evidence For Quantum Effects In The Brain

Nobel laureate Roger Penrose is widely held to be one of the most brilliant living physicists for his wide-ranging work from black holes to cosmology. And then there’s his idea about how consciousness is caused by quantum processes. Most scientists have dismissed this as a cute eccentricity—a guy like Roger gets to have at least one crazy theory without being demoted from the smartypants club.

    Does Infinity - Infinity = an Electron

    S10 E30 - 15m 35s

    What do you get if you take something that’s infinitely massive and combining with something else that’s negative infinitely massive? You get a single electron, at least that’s what it looks like in our most precise way of describing the quantum world.

    What Does An Electron Actually Look Like?

    S10 E29 - 13m 39s

    What does an electron really look like? I mean, if we zoom in all the way. Is it a sizeless speck of charge? Is it a multidimensional vortex of quantum strangeness? Is it the boundary of a tiny universe with universe-electrons of its own? Let’s find out.

    The NEW Ultimate Energy Limit of the Universe

    S10 E28 - 16m 35s

    The James Webb Space Telescope has found a quasar that simultaneously breaks a century-old theoretical limit and may explain the conundrum of gigantic black holes in the early universe.
