NUCLEONS TO BLACK HOLES. “Consider first a cold non-rotating assembly of N nucleons. If its mass exceeds a critical mass of the order of 2Mo it will collapse spontaneously, presumably to form a Schwarzschild black hole.” https://lnkd.in/dAr7QTt View in LinkedIn

DERIVATIVE LAW. “Using the conjectured proportionality between black-hole entropy and horizon area, Bekenstein proposed a generalized version of the second law of thermodynamics: The sum of black-hole entropy, SBH, and the ordinary entropy of matter and radiation fields in the black-hole exterior region, S, cannot decrease.” https://lnkd.in/d3sfhP6 View in LinkedIn

THEY JUST SEEP OUT. “The interesting thing about the "creative openings" is that they occurred in a thoroughly random order, and had to be fitted together (like a jig-saw puzzle) to make continuity. While the author has learned to trust the commentary of these preconscious sources, the reader should be warned that they rest on this kind of intuition.” (Professor John Curtis Gowan) https://lnkd.in/d4sDpAu View in LinkedIn

SURFACE AREA. “In particular, the formal analogy between the second law of thermodynamics and Hawking’s area theorem, which states that black-hole surface area cannot decrease, motivated Bekenstein to conjecture that the required black-hole entropy is proportional to its surface area. https://lnkd.in/d3sfhP6 View in LinkedIn

ENTROPY AS INFORMATION. “It was while attempting to resolve this apparent paradox that Bekenstein came up with the bold idea to associate entropy with black holes – entropy as the measure of (missing) information about the black-hole internal state which is inaccessible to external observers.” https://lnkd.in/d3sfhP6 View in LinkedIn

FOOTNOTE. “The total entropy of a system either increases or remains constant in any process; it never decreases.” https://lnkd.in/d_98ekG View in LinkedIn

UNTHINKABLE VIOLATION. “In particular, to external observers it seems that the entropy of the visible universe decreases as the (entropy-bearing) object disappears into the black hole.” https://lnkd.in/d3sfhP6 View in LinkedIn

BRILLIANT. “In this gedanken experiment, the thermal entropy of the tea disappears behind the black-hole horizon. Hence, at first glance, it seems that the second law of thermodynamics, which states that entropy cannot decrease, is violated in this physical process.” https://lnkd.in/d3sfhP6 View in LinkedIn

TEA WITH MILK PLEASE. “The legend says that it all began with a cup of tea and two genius physicists, Professor John Archibald Wheeler and his young student Jacob David Bekenstein, who tried to figure out what happens to the second law of thermodynamics when the cup goes down a black hole.” https://lnkd.in/d3sfhP6 View in LinkedIn
