Category: Sc & tech
- Astronomers announced that at last they had seen the unseeable: a black hole.
- A black hole is a cosmic abyss so deep and dense that not even light can escape it.
- The black hole has been found in the heart of the galaxy known as Messier 87, some 55 million light-years away from here.
- The black hole is about seven billion times more massive than the sun.
- Einstein, from whose equations black holes emerged, was loath to accept it.
- If too much matter is crammed into one place, the cumulative force of gravity becomes overwhelming, and the place becomes an eternal trap, a black hole. Here, according to Einstein’s theory, matter, space and time come to an end and vanish like a dream.
