Thank you for that fab link.
I too am interested in black holes [BH] and big bangs [BB], but
from a quantum view point.
A BH doesn't stop Planck's clock, rather, it (locally, islandically) stops all actual transmutative scintillation of flux quanta. That's why a BH doesn't 'radiate' a signature (other than its apparent ideal sensorial absence) of its hidden presence in quantum~reality. Yet it still exhibits a kind of conservational quantum phenomena of 'reversing creation.' See Doug's QVH Table. This quantum~conservation of actuality greatly omniffers classical, dialectical "zero sum game" CONservation. Still and yet, violating conservation (regardless classical, regardless quantum) there is a huge 'price to pay,' a huge 'penalty,' when any local game ends by self extinction by attempting to 'sneak by' memes of natural~comservation. Black holes tend to commit suicide. In our bodies, our cells do that too. It's called "cellular apoptosis." Cosmically it's called, "a black hole ending self."
A BH turns actual flux (keeping it simple: fermions and bosons) into isoflux (Heraclitus' "nature hides").
A BH hides actuality, rather, portions of actuality.
(This 'hiding' has a fiat money metaphor on earth
right now: Keynesian Central Bankers and their brokers
Gravity has a universal advantage of perfect superluminality as zero latency: gravity isn't a function of time.
Acceleration as a function of time is a symptom of gravity, n¤t its 'identity' as Einstein surmised. Gravity's affectation is everywhereings, everywhenings, always!
(What those scientists, under Dr. Wu, are struggling
with is a meme of Maxwellian heat death borne of a biggest BH
which eats (hides) all.
There are many BHs. Each one appears to locals as "death
of their universe."
