Adam Brown is back! General relativity is said to be the most beautiful idea the human mind has ever produced. Most of us will never get to fully appreciate its elegance by taking the 20-lecture graduate course Adam taught on it at Stanford. But in this episode, Adam distills the key idea at its heart so clearly and compellingly that even I could keep up lol.
Highlighted moments
inertial forces always have a charge given by the inertial mass. Gravity has a charge. The charge of gravity is given by the inertial mass. So, Einstein leapt, could it be the case, and this was his central idea, could it be the case that gravity itself is an inertial force?
“whenever you try and take something that is curved and pretend it's not curved, you will inevitably end up being wrong about what is and is not a straight line.”
“already once you're within 3gm over c squared, orbiting is counterproductive if you're trying to stay away from the black hole.”
“You are doomed, but you are not dead. You are only for sure dead once you hit the singularity and get spaghettified, get mangled by the tidal forces. But for a large enough black hole, you can be doomed and not even know it.”
