Equivalence principle is the first and foremost concept in Einstein's General Theory of Relativity. In this video, I have explained the equivalence principle and firther details. i have first introduced the different challenges that you might face while learning General Relativity and then the solutions. I have also traced bact to the history and the roots of equivalence principle from Aristotle, Galileo upto Einstein. I have also explained in details when Einstein found out the equivalence principle and his thought experiment in the elevator. I have also explained the strong, weak and the Einstein equivalence principle and how matter causes the spacetime to curve, thereby causing the light to bend and take the geodesic path.
Correction
39:27 - When the lift is accelerating downwards, the light will move upwards and vice-versa. Sorry for the mistake. Thank you @astronomy-channel
