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

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

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

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

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

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

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

THE HOLY GRAIL. “The generalized second law of thermodynamics (GSL) provides a unique relation between thermodynamics, gravitation, and quantum theory. It therefore allows us a unique glimpse into the elusive theory of quantum gravity.” https://lnkd.in/d3sfhP6 View in LinkedIn

UNPROVEN. “Despite the general agreement that the GSL reflects a fundamental aspect of the quantum theory of gravity, there currently exists no general proof (that is, a proof which is based on the fundamental microscopic laws of quantum gravity) for the validity of this principle.” (GSL = the generalized second law of thermodynamics). https://lnkd.in/d3sfhP6 View in LinkedIn
