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.
