SCIENCE BEHIND IT : BLACKHOLES

A black hole is a region of spacetime exhibiting gravitational

acceleration so strong that nothing, not even light, can escape from it.
Albert Einstein first predicted the existence of black holes in 1916, with
his general theory of relativity. The term “Black Hole” was coined many

years later in 1967 by American astronomer, John Wheeler. The first

physical black hole was spotted in 1971.

In 2019, the Event Horizon Telescope (EHT) collaboration released the

first image ever recorded of a black hole. The black hole was found in

the center of galaxy M87 while the telescope was examining the event
horizon, the area past which nothing can escape from a black hole. The
image maps the sudden loss of photons.It also opens up a whole new

area of research in black holes, now that astronomers know what a

black hole looks like.
