Unpopular 2022 Musk is the same Musk that led Space X from its founding to its current role of revolutionizing access to space, and was quite popular until a year or three ago. And yes, he accomplished that by hiring a bunch of ridiculously smart people, motivating them to work hard and succeed, and taking risks that the entrenched players wouldn't take. I'm not worried one bit about Space X continuing to do more of what it's done so far. Sure, I do wish other competitors would step up, but so for no one else has. The entrenched bureaucracies like NASA and Boeing/Lockheed have proven unable to innovate. The other upstarts have overly modest goals like 6-minute entertainment rides.

If Bezos really wants to revolutionize space, the best thing he could do is probably to just buy Twitter from Musk and immediately ban Musk from it. Maybe then Musk would get back to focusing on space.

this is all very theoretical but here is my best guess.

lets call the two observers A and B. and lets assume they are not negatively impacted by the physics of where they are at. if they were on opposite sides of the black hole, they would not be able to see one another as the black hole which is solid would block the view. But lets say the black hole is transparent. In this case you will still see nothing due to the gravity well. If you look towards the center of the black hole, it would be absolute darkness as no photons are able to reach your eyes due to the pull towards the center. if you turned 180 degrees away from the center, you would be blinded by the amount of light coming at you from the event horizon, this will be caused by the inverse gravitational lenseing that would occur on the inner "surface" (not an actual surface but an appox of the event horizon). if you turned 90 degrees to the left or right and look along the perimeter of the event horizon you would see a distorted image of observer B on both sides of you. While the gravity prevents the light from escaping the black hole it does not prevent it from orbiting the black hole like a satellite. so some of the light leaving observer B would travel parallel to the event horizon perhaps perpetually. looking up or down in the same manner would give similar results but, looking up you would see the top of obsever B's head. if you look down you would see observer B's feet. crazy thing is if observer B was not there, you would see images of your self. if you looked to your right you would see the left side of your self. look down and see the bottom of your feet ect.

TLDR: you would not be able to see across the hole as it would be darkness, looking behind you would be blindingly bright, and looking up, down, left, or right you would see 2 distorted fuzzy dim copys of observer B along with everything else that has ever come into this space.

Article:

SEOUL, Dec 30 (Reuters) - South Korea conducted a successful test flight of a solid-propellant space launch vehicle, the country's defence ministry said on Friday.

Earlier on Friday, South Korean media reported multiple citings of an unidentified flying object over the country's airspace.

In June, South Korea's second test launch of its domestically produced, liquid-engine Nuri rocket successfully placed several satellites in orbit, taking a major step in progressing its space programme.

I prefer that someone makes space exploration / travel a reality than not.

I'm fairly convinced that Mr Musk is going through some sort of mid life crisis or breakdown. The rockets still fly though.

He's said he wants to die on Mars. If he can manage that trick then people will live on Mars. If only to provide funeral services.

The twitter nonsense won't impact SpaceX very much because SpaceX is providing services to the US government.
