Black Hole@konstructivizm
The first ideas about gravitational objects so dense that even light cannot escape them arose as early as the 18th century. However, the true scientific foundation was laid in the 20th century with the work of Einstein. For a long time, black holes remained purely theoretical objects, mathematical wonders.
Forty years after the first serious sketches in 1978, in 2019, humanity finally saw a direct visual "portrait" of the shadow of a black hole (M87*).
