What helps astronomers locating a black hole is a circular orbit of photons that
surround it. This phenomenon is known as, the innermost stable circular orbit,
as it borders this gigantic, forceful spot. Recently, it was discovered that black
holes generate energy called, hawking radiation. This radiation is responsible
for the shrinkage of a black hole until it evaporates entirely after billions of
years. Scientists have established a theory that predicts what happens to an
object when it enters a black hole. They hypothesized that an effect called,
spaghettification, will happen. First, when an object comes close enough to the
black hole, its gravity becomes intensive, and the bottom part of it is pulled
first. The bottom part will stretch away as the gravity of a black hole is not
constant as the rest of the universe bodies. The top of the object will get
twisted as it drifts closer to the black hole, and the whole object will get
thinner and taller like a spaghetti.
