The question of what the Big Bang really represented still bamboozles cosmologists — and Hawking provided more than one answer.
Credit: Thomas Hertog and Jonathan WoodStephen Hawking died five years ago, but his brand lives on. was the first of more than a dozen bestsellers by the iconic theoretical physicist. The new book— by Thomas Hertog, Hawking’s last collaborator — concerns his final theory. I can’t resist saying that it’s about time.
In the 1960s, the discovery of the cosmic microwave background, radiation that suffuses all of space and that was predicted by the Big Bang theory, seemed to settle the debate. But new controversies broke out — just as Hawking entered the fray.In 1981, at a meeting on cosmology at the Pontifical Academy of Sciences in the Vatican, he brazenly went against a core tenet of the Big Bang theory, proposing that the Universe had no moment of creation.
The gushing provides little real sense of Hawking’s character. Nor does it do justice to key people such as Jacob Bekenstein, whose work on entropy in black holes Hawking initially rejected and then adopted as central to his own theories.
