Yes. There are several different ways to measure distance over cosmological
scales, and his claim and mine use different ones. I am not expert on this.

From here, on earth, we see clocks slow to a hault At:
A.) The event horizon of a black hole.
B.) The cosmic horizon ( the start of the big bang ).

But our cosmic horizon is not necessarily at the big bang. Indeed the
expectation is that the universe is considerably larger than our cosmic horizon.
In that case, things at the cosmic horizon are as I said.

OK, you didn't make it up.


A TRUE black hole is a singularity.

The term "black hole" refers to the region inside its event horizon, not just
the singularity inside.


An APPARENT black hole, i.e. a black hole CANDIDATE, isn't a black hole.

Astrophysicists today generally accept that the compact objects at the center of
most (if not all) galaxies are indeed black holes. The "candidate" has been
removed over the past decade or so.


For example, a supermassive black hole could be modelled by
a large cluster of very dark objects. ＞＞

Except that their size is too small by orders of magnitude to be ordinary matter.
