" And one cold Tuesday in December, when Marie-Laure has been blind for over a year, her father walks her up rue Cuvier to the edge of the Jardin des Plantes." Here, ma chérie, is the path we take every morning. Through the cedars up ahead is the Grand Gallery." " I know, Papa." He picks her up and spins her around three times. " Now," he says, " you're going to take us home." Her mouth drops open." I want you to think of the model, Marie." " But I can't possibly!" " I'm one step behind you. I won't let anything happen. You have your cane. You know where you are." " I do not!" " You do." Exasperation. She cannot even say if the gardens are ahead or behind." Calm yourself, Marie. One centimeter at a time." " I'm far, Papa. Six blocks, at least." " Six blocks is exactly right. Use logic. Which way should we go first?" The world pivots and rumbles. Crows shout, brakes hiss, someone to her left bangs something metal with what might be a hammer. She shuffles forward until the tip of her cane floats in space. The edge of a curb? A pond, a staircase, a cliff? She turns ninety degrees. Three steps forward. Now her cane finds the base of a wall. " Papa?" " I'm here." Six paces seven paces eight. A roar of noise - an exterminator just leaving a house, pump bellowing - overtakes them. Twelve paces farther on, the bell tied around the handle of a shop door rings, and two women came out, jostling her as they pass.Marie-Laure drops her cane; she begins to cry. Her father lifts her, holds her to his narrow chest." It's so big," she whispers." You can do this, Marie." She cannot. "

" The fireworks continued to burn and spread all over the school that afternoon. Though they caused plenty of disruption, the other teachers did not seem to mind them very much." Dear, dear," said Professor McGonagall sardonically, as one of the dragons soared around her classroom, emitting loud bangs and exhaling flame. " Miss Brown, would you mind running along to the headmistress and informing her that we have an escaped firework in our classroom?" " Thank you so much, Professor!" said Professor Flitwick in his squeaky little voice. " I could have got rid of the sparklers myself, of course, but I wasn't sure whether I had the authority..." Beaming, he closed the classroom door in Umbridge's snarling face. "

" Inflation is continuous and eternal, with big bangs happening all the time, with universes sprouting from other universes. In this picture, universes can “bud” off into other universes, creating a “multiverse.” In this theory, spontaneous breaking may occur anywhere within our universe, allowing an entire universe to bud off our universe. It also means that our own universe might have budded from a previous universe. In the chaotic inflationary model, the multiverse is eternal, even if individual universes are not. Some universes may have a very large Omega, in which case they immediately vanish into a big crunch after their big bang. Some universes only have a tiny Omega and expand forever. Eventually, the multiverse becomes dominated by those universes that inflate by a huge amount.
In retrospect, the idea of parallel universes is forced upon us. "
