A black hole is Spaghettification: a cosmic stretch machine

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. If someone traveled inside a black hole, they would experience a tidal force, or 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.^[1] 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, a one would be stretched out in a process known by scientists as spaghettification. 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.^[2]

[P1] In black holes, the gravity increases very quickly. [P2] If one descended into a black hole, the gravity would be larger on their first point of entry. [P3] The difference in gravity would stretch them out, resulting in spaghettification.
