Every equation says that time starts to slow
down the closer you get to the event horizon,
and it completely stops at the event horizon.

No, you are looking at the wrong formulae. We
are talking about falling in.

I am talking about falling in too.

But it's people on the outside looking at them
falling in, that will see time slowdown.

That is a problem with the light climbing out, not the stuff falling in. No time stoppage, cross the event horizon in finite exterior time.

The speed of light is also the speed of time.

To external viewers, it looks like the spaceship
has stopped in mid-air, because our direction of
time is no longer really used to measure its
progress anymore.

No you are wasting effort on the light climbing out, rather than sticking with the bits that fall in.

Time and lightspeed are inextricably linked. This is as Einstein says,
are you now disagreeing with Einstein?

This has nothing to do with Einstein's Relativity.
It has to do with QED, and the quantum vacuum
energy. Relativity has nothing to say one way or
another about whether gravity is a force or energy,

Yes, it does.

it just looks at its effects without any context.

False.

But what lies beneath Relativity is a different
domain.

One not subject to experimental falsification, and of no interest to me. "Reality" like "Truth" is something Nature does not show us.

This is the area of full experimental falsification, it's called the
Standard Model!

I'm talking about our container universe. From the
outside, we'd be seeing the container universe
shrinking through Hawking Radiation.

No, since every bit of matter that ever entered the black hole, always enters at the Big Bang event. Time zero. For all observers.

No, only for observers inside the blackhole. Observers outside the
blackhole will see objects falling into the blackhole at different
various times. Observers inside the blackhole will always think that it
all came in at exactly the same time, i.e. at the very beginning.

But how would we detect the Hawking radiation
from within the blackhole?

I say as ZPE, but you did not like that.

We'd likely see that the borders of the event
horizon are shrinking too, and backward in time.

Nope. Crossing the event horizon is always time zero, for all interior observers.

But that's not what we're talking about, we're talking about Hawking
radiation, which is objects leaving the blackhole. That's always going
to be at the end of the universe.
