Then light could escape it and it wouldn't be a black hole.

We've been through this already.

 

Not if it absorbs photons.

Not if it absorbs photons.

 

That would just be a thing which is dark. Not a black hole.

As you will know from being in the world, there is always some reflection from dark objects even if only at the critical angle.

 

And we come back again to Sag A.

By reducing the gravity of a suttyverse black hole, you've necessarily increased its physical size

In order to prevent the space-time curvature reaching infinity, you have to spread out the mass. If you spread out the mass, you increase the size. If you increase the size, S2 ought to hit Sag A.

The type of matter found in black hole would be very different to anything found on earth and it would still have a stronger gravity and higher density than anything else in the universe.

If it were dense enough to match the observations of Sag A then it would have infinite space-time curvature within it and would collapse to a point. If it were not dense enough Sag A would get an S2 in the face.

 

Also, things that absorb light and don't emit it get hot. Hot things emit light.

 

There's no amount of "that doesn't sound right to me" which can measure up to maths and data.

As long as you refuse to accept that you will live in ignorance.

Thought I would share this I found today about multiple universes and other stuff especially about cosmic inflation and a non infinite universe, facts that are still unproven.

This is part of the multiverse model which we were discussing much earlier in the thread. Whilst it's unlikely that we could ever directly observe these other universes, we might reach a point where we can say with high confidence that they exist and how they differ from this universe.
