"The Milky Way’s central black hole, named Sagittarius A, is a behemoth at 4 million times the mass of the sun. Scientists now think that such a supermassive black hole sits at the center of most large galaxies. "
Question: Is there a type of weak black hole that something could travel into and also escape from?

Disney's The Black Hole (1979) was very weak, and I believe several of the cast's careers did escape it eventually. Ernest Borgnine's may have been lost forever, though.

                                        So relatively no loss of information in that theoretical black hole.
With a little research, that mass of black hole is right at 16.5x the diameter of our sun. Quite a small pinprick to be holding the milky way together! I'm now proud to be a Sagittarius.

This might be an explanation for the Lambda constant, a theory Einstein considered his biggest blunder, one however that post-mortem turned out to be right after all.

                                        I'm a pretty feepy mathematician, so I understand this stuff fairly poetically. I keep seeing black holes as sort of like the drain in your bathtub. It's probably not very much like that though. I think scientists' knowledge of the interior of a black hole is like the old map-makers, who peopled the edges of the known world with monsters.

                                        The Scientific American article says we do not understand black holes correctly yet.
