I'm not sure it was known for certain that Sagittarius A- was a black hole at the time of posting.
In October 2018, it was concluded that Sagittarius A- was a black hole with certainty beyond a reasonable doubt based on observations of gas/dust moving at otherwise impossible speeds. 3C)

You could not fail to learn from Phil, the enthusiasm from an expert is just epic to watch. This guy needs a syndicated series, reminds me of the great James Burke! The view must be great, standing on the shoulders of Giants. I know I look up to you, keep on doing these!

So I jumped to a black hole in Elite: Dangerous, and had to emergency stop 45. 6km from the event horizon. Should I technically have been able to escape? (I was but I'm not sure if it should have actually been possible)

Black hole evaporation is confusing as the matter generates antimatter which can loose on of it only at the event horizon how will this eat up matter inside the event horizon. I dont understand how that can escape.

7: 25 -compaired to either black hole,
a star still has substansial size,
and when it gets close to either black hole,
it can be distrupted via tides- CrashCourse Poems

I've got it.
The only way to survive falling into a black hole is to be _made_ out of spaghetti, because if you already are spaghetti, how can you be spaghetified?

IT's a shame you talk so quickly. There are incredible facts in here but this is very hard to keep up with, as there is a lot of new information delivered rapidly.

I don't get it gravity depends on mass and distence. not density right. if density increases mass remain constant it just the volume that decreases

I think it is interesting that we don't seem to find things until someone predicts that they should exist and then whamo we find them.
