Hawking's theory, first published in 1971, states that there is a group of black holes in the Universe,
As part of the study, scientists wanted to fixthe curvature of light from objects near which supermassive dark holes move. Scientists observed with a telescope for seven hours, but there was not a single change in the brightness of the stars due to passing by the black star.

In case Hawking's theory was correct, forFor seven hours, physicists could have recorded at least a thousand changes in the light of the stars, but scientists were able to detect only one such phenomenon. Accordingly, such primary black holes can constitute no more than 0.1% of the mass of all dark matter.
