I'll let the pictures do the talking

We are bounded in a nutshell of Infinite Space: Week 11: Free Form #16: I'll let the pictures do the talking 

 Stephen Hawing came to Harvard. Possibly one of the most influential physicists, cosmologists, science promoters, writers, of the last century, Dr. Hawking is a true stalwart. Not only because of his disability and the drive it takes to continue living and working to change the world, he is an unadulterated view of someone who has fought every step of the way to finally be the top in their field. Now, he came to Harvard as part of the opening of the Black Hole Initiative (hopefully I get a chance to work there for a while), where mathematicians, physicists, philosophers, and astrophysicists will work on better understanding the nature of black holes and the important role they play for the universe. Professor Hawking, on his part, went on to give a full lecture on quantum black holes. He started out with the basic premises, the nature of general relativity and space time, to later move on to the more interesting portions. The talk shifted to Schwarzschild, the dawn of the theory of black holes, and then to Richard Feynman and Arthur Penrose, people who further developed the theory and saw the consequences of black holes on structure formation. 



He then spoke of the components of black hole theory he had established in the past, especially the understanding of how black holes begin to fade due to radiation emission, called Hawking Radiation. This allows for a black hole to disappear after a great deal of time, but in this come the theoretical and frontiers of new black hole science: information theory. This aspect of black holes, thought up by Hawking, Strominger, and Perry, attempts to explain how black holes are a way that, originally, information could be completely vanished from the universe. Imagine you were to place an encyclopedia into a black hole, all the pages with all their facts would fall towards the singularity, ripped apart by tidal forces and spaghettified (for not humongous black holes), never to be seen again in our universe (yes, he got into the idea that black holes could very well be a gateway to another dimension). However, this is where the idea becomes very interesting, for black holes grow larger and their radius expands as they become more massive, as more things are thrown into it, and as the black hole eventually radiates out its existence, in theory the information first lost beyond the event horizon could come back in the form of thermal energy, technically not impossible to be turned into physical matter with all the pages on the Rhine, rhinitis, and rhinoceroses. If you want to learn more on how these black holes become the unification of quantum mechanics and general relativity, one of the main pursuits of modern physics.
