Till now no one has seen a black hole directly.

Explanation:

Objects whose gravity fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace.
The first strong candidate for a black hole, Cygnus X-1, was discovered by Charles Thomas Bolton,Louise Webster and Paul Murdin in 1972 by indirect methods.
