A physicist proves that black holes cannot exist

[Hermit]

The air pressure at Valencia Co Kerry now at 16.55 pm is 2021 millibars. The air pressure at the Mull of Kintyre , Scotland is 2017 millibars, a difference of 4 millibars. Where is the barrier between the two locations?

Your question is mute, there is no vacuum in or between those locations. A vacuum cannot exist next to a gas pressure system without a barrier.

Quasars are visible to high-powered instrumentation. They are the brightest things in the universe and are created by matter burning out of existence around the rim of black holes. They were predicted and theorised before they were observed.

Quasars have not been 'observed', they are still an object of speculation based on one school of data interpretation related to light that the quasar itself is supposed to have emitted. It's a circular argument in this case. The Quasar must exist based on how we are interpreting our observations.

Confusion reins when the data stops supporting the theory. Maybe the quasars where never there in the first place? Of course, this is a modern heresy to even suggest. No indeed, they will simply bend their very flexible theory some more.

The Case of the Disappearing Quasars

A dozen quasars in the early universe appear to have shut down in just a few years, baffling astronomers
