Black holes have such a force that even light can
not escape the pull. As you near the
event horizon, "The event horizon acts like a kind of one-way membrane, similar to the "point-of-no-return" a boat experiences when approaching a whirlpool and reaching the point where it is no longer possible to navigate against the flow. Or, to look at it in a different way, within the event horizon, space itself is falling into the black hole at a notional speed greater than the speed of light" ("The Physics").
the area closest to the black hole, the gravitational
strength is so strong that light appears to bend. This
bending of light creates the effect of a warped or
inward caving type of phenomenon of dense clouds shrouded
in a gloomy distance (Redd).
Black holes are invisible to the naked eye
because light can not escape the event horizon.
To circumvent this phenomenon, special telescopes
and scientific instruments have been developed to aid
scientists in discovering the elusive peculiarities.
By studying the
behavior "Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them - emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others ("Black Holes").
of matter in the vicinity
of a black hole, scientists can determine the probability
of their existence (Smith).
