Today's Black Holes are much weaker.

Why would you think that ?

Because it's observed.

Relf was there 12.5 billion years ago to observe it
and has returned to keep us all informed.
See why I say [I'm] STILL and idiot ?

It took 12.5 billion years for the light to get here;
we see it as it was then, 12.5 billion years ago.

As entropy increases, our universe is getting less "dense/hot/powerful".


How long would it take light to get to us from the Sagittarius A black hole?

Don't laugh. The European Southern Observatory thinks they have a picture!
