Zhang Yuan was pondering a question, if anti-gravity technology truly emerged, could human civilization break free from the predictions of New Civilization History? In previous calculations, it seemed this aspect had not been considered.
John was still enthusiastically immersed in his own thoughts, "I'm wondering if black holes are a Bose-Einstein condensate at the quantum phase transition critical point? Only then would they have some strange properties... just like Bohr said, when matter falls into a black hole, it can only approach the singularity infinitely close but can't actually reach the singularity."
"There's a slight possibility..."
The two discussed spiritedly for a long time before the room slowly quieted down.
John, stubborn and pessimistic, insisted that humans could not achieve true anti-gravity technology, believing all technological advances were merely fleeting.
"Whatever you say..." Zhang Yuan replied irritably.
