The Big Bang
Another way of dealing with Loschmidt's paradox is to see the second law as an expression of a set of boundary conditions, in which our universe's time coordinate has a low-entropy starting point: the Big Bang. From this point of view, the arrow of time is determined entirely by the direction that leads away from the Big Bang, and a hypothetical universe with a maximum-entropy Big Bang would have no arrow of time. The theory of cosmic inflation tries to give reason why the early universe had such a low entropy.

Famous quotes containing the words big bang, big and/or bang:
“There aren’t any good, brave causes left. If the big bang does come, and we all get killed off, it won’t be in aid of the old-fashioned grand design. It’ll just be for the Brave New-nothing-very-much-thank-you. About as pointless and inglorious as stepping in front of a bus. No, there’s nothing left for it, me boy, but to let yourself be butchered by the women.”
—John Osborne (1929–1994)
“It is not only a question of who is responsible for very young children. There is no longer anyone home to care for adolescents and the elderly. There is no one around to take in the car for repair or to let the plumber in. Working families are faced with daily dilemmas: Who will take care of a sick child? Who will go to the big soccer game? Who will attend the teacher conference?”
—Fran Sussner Rodgers (20th century)
“Don different from those regal Dons!
With hearts of gold and lungs of bronze,
Who shout and bang and roar and brawl
The Absolute across the hall,”
—Hilaire Belloc (1870–1953)
