spaghettification

Spaghettification is a hypothetical process where an object is stretched and squeezed under extreme gravitational forces. This phenomenon occurs when an object, such as a star or a person, gets too close to a massive gravitational source, like a black hole. The gravitational pull on the side of the object closer to the black hole is significantly stronger than the pull on the farther side. This difference in gravitational force creates tidal forces that stretch the object vertically while compressing it horizontally.

The term "spaghettification" is derived from the visual resemblance of the stretched object to a strand of spaghetti. The intensity of these tidal forces depends on the mass of the gravitational source and the distance to it. For stellar-mass black holes, spaghettification can happen even outside the event horizon. However, for supermassive black holes, which are much larger, the tidal forces at the event horizon are weaker, meaning an object might cross the event horizon before being spaghettified.

While currently a theoretical concept, spaghettification is a key prediction of Einstein's theory of general relativity. Astronomers have observed phenomena that are consistent with spaghettification events, such as tidal disruption events where stars are torn apart by black holes. These observations provide indirect evidence for the existence and behavior of black holes and the extreme gravitational environments they create. Understanding spaghettification helps scientists test and refine our models of gravity and the universe.
