Tidal force
A force arising because an uneven gravitational field exerts different magnitudes of gravitational pull on different parts of an object, thereby producing stretching and compression.
Timeline (last 90 days)
A black hole's tidal forces stretch a nearby object radially while compressing it laterally, ultimately stretching it into a slender "noodle" shape, a process called spaghettification.
Any celestial body (such as Earth or the Moon) exerts tidal forces on objects near it, and their magnitude depends on the degree of non-uniformity of the gravitational field.
For stellar-mass black holes, the region where tidal forces are strong enough to tear objects apart lies far outside the event horizon; for supermassive black holes, tidal forces near the event horizon are instead relatively small, so an astronaut might safely cross the horizon first and then be torn apart near the singularity.
An observer falling into a black hole themselves experiences a finite proper time and is torn apart by tidal forces before reaching the singularity.
A black hole's tidal forces can be strong enough to tear apart atomic structure.
