Maybe something like dark energy repulsion avoid the black hole
creation?

Luigi Caselli


I think that all objects currently thought to be black holes will turn
out to be something similar to neutron stars.

Like all computers, the big simulator doesn't like working with
infinities!
Doesn't that prove to be a bit of a problem for just about everything
in phyics, then?

The entire subject is built around 'Deperately seeking THE perfect
convergence'.

Only black holes can destroy the space structure, other infinities in
physics are not so problematic...
In a black hole you must have different mathematics, physics and so on.
Really to weird for the Big Computer...
IMHO there must be some effect (I'm thinking about something lik dark energy
repulsion at small scale) avoiding infinite collapsing even for a
supermassive star.

Yes, dark energy could play a role.

Note this ressponse by astrophysicist Steve Carlip to my question a
while back:

"Double-A wrote:
I was wondering if it could be said to always be the case that once
the event horizons of two black holes join in any way, even to form a
neck, that the two black holes can never again be separated? That
from that moment on, merger is inevitable?

Yes, at least within standard general relativity (and provided that
there's no negative energy around to mess things up). This is a
consequence of work by Hawking on the general behavior of black
holes. If you want an exact technical reference, see Theorem 12.2.1
in Wald's textbook, _General Relativity_.

Notice that he is mindful of the effect of dark energy on black hole
objects.

There you go, Luigi! Great minds think alike!
