It’s not mass that is needed as much as a density; that is, a combination of mass and volume. The earth would form a black hole if it was crushed to about 0.7 inches across. But that would of course require an almost impossible amount of energy. Such energy is found in the gravitation potential of very large stars, however. But their event horizon is at least a few miles across, not just 0.7 inches.
Ok thank you I just did the basic math and knew I was missing something. Then I read your reply and that helps a lot, and thank you for your time and explaining it instead of treating me like I was dumb.
