What is a black hole?

A black hole is Spaghettification: a cosmic stretch machine

Question: What is a black hole?
Position‹4 of 4: Inside a black hole
Argument‹2 of 3›: A black hole is Spaghettification: a cosmic stretch machine

If one were to enter a black hole, they would be stretched apart by the force of gravity.

The argument

A black hole is a mass concentrated into an infinitely tiny point. This causes immense and strange gravity, which gets more and more intense as one gets closer to the center. The unusual part is not the strength of that gravity but how sharply it changes over a short distance, and it is the change rather than the strength that determines what happens to anything falling in. If someone traveled inside a black hole, they would experience a tidal force — a difference in gravity — between their head and feet. Because the gravity is increasing so rapidly as you draw near the center of a black hole, your head, assuming you descended feet first, would experience much less gravity than your feet. In everyday circumstances such a difference exists too, but it is far too small to notice, since the gravitational field barely changes across the height of a person. Near a black hole the gradient becomes steep enough that the two ends of a body are, in effect, being pulled by very different forces at the same moment. These tidal forces would not bode well for us humans, or any object traveling into a black hole. When the head and feet are pulled upon differently by the black hole's gravity, one would be stretched out in a process known by scientists as spaghettification. Nothing is holding the body together strongly enough to resist a difference of that size: the forces binding it are simply overwhelmed. It would stretch you out, breaking your body in half and eventually reducing you, or any object entering a black hole, into a thin rope of atoms.

Premises

[P1]A black hole concentrates mass into an infinitely tiny point whose gravity intensifies sharply toward the center, so an object falling in feet-first would feel far stronger gravity at its feet than at its head — a tidal force. [P2] This differential stretches the object out in a process scientists call spaghettification, eventually pulling it apart into a thin rope of atoms. [C] Therefore, inside a black hole, an object undergoes spaghettification — a cosmic stretch machine.

Counter-arguments

This isn't the case for all black holes. For relatively small black holes closer to the mass of our sun, spaghettification would take place. However, in larger black holes the gravity increase is spread out over more distance. Therefore, the tidal force is not as large and spaghettification would not take place.

Rejecting the premises

[Rejecting P1] Large black holes don't increase quickly enough to be significant.
