I'm not sure about the numbers
U= − GMm/rThe first mass m is supposed to be at infinity that means it exerts some potential energy U to escape from the surface of mass M with radius r and approach infinity , when mass m is at infinity ....
Infinity (symbol: ∞) is a concept describing something without any bound or larger than any natural number. ....
whether slower or faster, I claim no actual test for escape velocity.

They did the test.Repeatedly.It was called the Apollo project.They actually did launch stuff from the moon.It behaved the way that equations (and everybody but you) say it should.

How much spoonfeeding of the obvious do you need before you accept that it's not "the rest of the world" who made a mistake; it's you.
