That is as long as the hole does not collapse. At the center there is no gravitational force. But if the hole collapses you will be crushed. Is that what you meant?

You may be correct about the universe if it is closed according to solutions to Einstein's general relativity equations. We can tell if it is closed because the angles of a triangle will not add to exactly 180 degrees.

If the universe if flat, the angles add to exactky 180 degrees. In this case and also if the universe is open, the GR solutions indicate that the universe is infinite.

Of course, that is just theory and does not have to be correct. But neither does your logic.

Observations suggest that the universe is approximately flat, so by ay of GR, it is approximately infinite.

Interesting concept- approximate infinity. At my rate of pay anything over a million dollars is approximately infinite.
