Instructor: Hong Liu
In this lecture, Prof. Liu first discusses four laws of black hole mechanics, and then relate them to laws of thermodynamics. He also outlines black hole information paradox.

Id like to express my undying gratitude for the open access initiative and particularly to anyone and everyone who has labored to realize this idea for people like me who are intelligent but can not seem to escape poverty. Thus I am destined to continue break my body in an attempt to provide legal tender and can not afford the money required to go to University; although that's all I wish I could do. I received my associates degree in Journalism/advanced English when I was just however I was to work full time to help my mother who became disabled. Also I was young and dumb and did not have a full grasp on the importance of schooling as it relates to quality of life. This comment has become entirely too much information and all I wanted to convey was that my nightly endeavors towards enlightenment and self-education have been ameliorated further by MITs open access. For this I am eternally grateful. For anyone it may apply to: go to college. Just don't go for pseudo-academic courses and degrees such as women's studies or anything that teaches you through the lens of post modernism and it's ugly cousins. Beware of the neomarxists as well. 🤙😉😱🤓

Hawking talked about a 'naked singularity. if a BH is defined by having an event horizon, then a naked singularity, if it exists, would not be a BH.

[@shayangfkk7948]

first a naked singularity was discovered by analyzing kerr black holes , technically when a^2 > G^2M^2 you would have an oscillating radius not a stationary one .

If BH is an ordinary QM object and spins like electron, proton etc., then does it imply they are also little BH? Green claims there are 194 types of BH, according to Ramanujan's mathematics. The argument between GR and QM seems to have a solution in the mathematics of quantum computers and the holographic representation somehow explains gravity.
