How many theories do I need to read? After I finish reading them do I need to eventually read them again, or is the mass-energy of the information they contained permanently transferred to my brain? Is there enough theory to accidentally collapse my brain into a black hole by absorbing too much mass? Does all theory contain the same potential for brain growth, or are certain theories more likely to drastically expand the mass of my brain? If the latter is correct, which theory do I need to avoid reading so my brain doesn't instantly collapse to within its Schwarzschild radius? If I do accidentally collapse my brain into a black hole, is the specific theory I read gone from the world forever due to the destruction of its quantum information? Or is that information not destroyed but instead stuck to the surface of my brain's event horizon? Once my black hole brain evaporates due to Hawking Radiation many eons in the future, will it be possible to use that radiation to reconstruct all the theory I've ever read? I need specifics here!
