Later, it was discovered by the Slipher and Hubble red-shift that the universe is indeed expanding, and even later, by Schwarz and company in 1998, that the expansion is accelerating - aka, dark energy. And the cosmological constant was re-introduced.Thanks to Grant Sanderson of http://www.youtube.com/3Blue1Brown for help with the fancy equation animation!REFERENCESThe Einstein Field Equationshttps://en.wikipedia.org/wiki/Einstein_field_equationsInterrogating the Legend of Einsteins Biggest Blunderhttps://arxiv.org/abs/1804.06768On the General Theory of Relativity (Einstein)https://einsteinpapers.press.princeton.edu/vol6-trans/110The Foundation of the General Theory of Relativity (Albert Einstein)https://einsteinpapers.press.princeton.edu/vol6-trans/158Cosmological Considerations in the General Theory of Relativityhttps://einsteinpapers.press.princeton.edu/vol6-trans/433Einstein Wrongly Criticizes Alexander Friedmannhttps://einsteinpapers.press.princeton.edu/vol13-trans/301Alexander Friedmann Corrects Einsteinhttps://einsteinpapers.press.princeton.edu/vol13-trans/363Einstein Admits his Mathematical Mistakehttps://einsteinpapers.press.princeton.edu/vol14-trans/77The Field Equations of Gravitationhttps://einsteinpapers.press.princeton.edu/vol6-trans/129George Gamowhttps://en.wikipedia.org/wiki/George_GamowMachs Principlehttps://en.wikipedia.org/wiki/Mach%27s_principleEquivalence Principlehttps://en.wikipedia.org/wiki/Equivalence_principleSean Carroll and William Press Paperhttps://preposterousuniverse.com/wp-content/uploads/cpt92.pdfSupport MinutePhysics on Patreon! http://www.patreon.com/minutephysicsLink to Patreon Supporters: http://www.minutephysics.com/supporters/MinutePhysics is on twitter - @minutephysicsAnd facebook - http://facebook.com/minutephysicsAnd Google+ (does anyone use this any more?) - http://bit.ly/qzEwc6Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute!Created by Henry Reich
