Discoveries of Hawking. From black holes, to hawking radiation to Big Bang to singularity.
Most of these came in the 70s and 80s. And in the 80s, his every discovery made a cover news in Time magazine.
That was one of the zeniths in Physics.
To balance off, he came up with not-so-correct theories too. Like the equation of the universe. These made a lot of headlines at that time. But didn't stand the scientific test.
Nice reading article, which isn't too technical.
