“See, everything that ever could possibly have happened, in the entire history of the universe right from the Big Bang up until now, _did_ happen -- somewhere. And _every_ possible difference means a different universe. Not just if Napoleon lost at Waterloo, or won, or whatever he didn't do here; what does Napoleon matter to the _universe_, anyway? Betelgeuse doesn't give a flying damn for all of Europe, past, present, or future. But every single atom or particle or whatever, whenever it had a chance to do something -- break up or stay together, or move one direction instead of another, whatever -- it did _all_ of them, but all in different universes. They didn't branch off, either -- all the universes were always there, there just wasn't any difference between them until this particular event came along. And that means that there are millions and millions of identical universes, too, where the differences haven't happened yet. There's an infinite number of universes, more than that an infinity of infinities, I mean you can't really comprehend it. If you think you're close then multiply that a few zillion times -- everything is out there.”

“The Hitchhiker's Guide to the Galaxy's definition of "Universe":The Universe is a very big thing that contains a great number of planets and a great number of beings. It is Everything. What we live in. All around us. The lot. Not nothing. It is quite difficult to actually define what the Universe means, but fortunately the Guide doesn't worry about that and just gives us some useful information to live in it. Area: The area of the Universe is infinite.Imports: None. This is a by product of infinity; it is impossible to import things into something that has infinite volume because by definition there is no outside to import things from.Exports: None, for similar reasons as imports.Population: None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is zero, therefore the average population of the Universe is zero, and so the total population must be zero.Art: None. Because the function of art is to hold a mirror up to nature there can be no art because the Universe is infinite which means there simply isn't a mirror big enough. Sex: None. Although in fact there is quite a lot, given the zero population of the Universe there can in fact be no beings to have sex, and therefore no sex happens in the Universe.”

“The Future is an illusion because, at the most fundamental level, Choice is an illusion. I am a believer in the theory, popular among physicists, that every time there is a Choice, the universe splits: both choices come to pass, but in now-separate universes. And so on, and on, with every choice of every particle, every atom, every molecule, every cell, every being, coming into being. In this universe of universes, everything happens, and every combination of things happens. Our universe is a mote of dust in an ever-growing dust-storm of possibilities, but each mote of dust in that storm is generating its own dust-storm of possibilities every instant, the motes of which in turn... But you get the general impression. Indeed to think of ourselves as single selves, and our universe as a single universe, is to be blinded, by the limitations of our senses and our consciousness, to the infinite-faceted truth: that we are infinite in a universe of universes that are each infinitely infinite...""An intriguingly intricate view of the world," I said (...)Pat Sheeran nodded. "And it is astonishing how little practical difference it makes," he said. "All my other lives are as inaccessible to me as if they did not exist at all. No doubt in other universes I am a beggar, a revolutionary thinker, an academic, an accountant; a drinker, a thinker, a writer of books; I lose a freckle, gain a mole, shade off into men nothing like me at all; I have sons, fire guns, live forever, die too young. Whenever any particle in this universe changes state, I am split and travel in both directions, multiplied. But here I am, suffering the illusion of unity in this endlessly bifurcating moment.Yet sometimes, I wave my arms for the joy of creating a spray of universes."I said startled at the implications, “Though it may make no practical difference, the implications are nonetheless startling.""Indeed," said Pat Sheeran. "I had immediately to file all the fiction on my shelves under Non-Fiction. For it is an unavoidable corollary of this theory, that Fiction is impossible. For all novels are true histories of worlds as real as ours, but which we cannot see. All stories are possible, all histories have happened. I, billion-bodied, live a trillion lives every quantum instant. Those trillion lives branch out, a quintillion times a second, as every particle in every atom in each mote of dust on land, in sea, and sky, and space, and star, flickering in and out of being in the void, hesitates and decides its next stage. All tragedies, all triumphs, are mine, are yours.""It is a curious and difficult thing, to think that all is possible. No, probable. No, certain," I said, attempting to grasp the largeness of the thought."That nothing is improbable.""It is a comforting thought, some nights, to this version of me, now," said Pat Sheeran, and we roared on.”

“Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?”

“Where did this whole thing begin? If what we think of as reality is just a pattern that somebody brought Outside, and the universe just popped into bring, then whoever it was is probably still wandering around giving off universes wherever she goes So where did she come from? And what was there before she started doing it? And how did Outside come to exist, for that matter?”That's Inspace thinking,” said Olhado. “That's the way you conceive of things when you still believe in space and time as absolutes. You think of everything starting and stopping, of things having origins, because that's the way it is in the observable universe. The thing is, Outside there's no rules like that at all. Outside was always there and always will be there. The number of philotes there is infinite, and all of them always existed. No mater how many of them you pull out and put into organized universes, there'll be just as many left as there always were”But somebody had to start making universes.”Why?” asked Olhado.Because-because I-“Nobody ever started. It's always been going on. I mean, if it weren’t already going on, it couldn’t start. Outside where there weren’t any patterns, it would be impossible to conceive of a pattern. They can’t act, by definition, because they literally can’t even find themselves.”But how could it have always been going on?”Think of it as this moment in time, the reality we live in at this moment, this condition of the entire universe-of all the universes-” You mean now.”Right. Think of it as if now were the surface of a sphere. Time is moving forward through the chaos of Outside like the surface of an expanding sphere, a balloon inflating. On the outside, chaos. On the inside, reality. Always growing-like you said, Valentine. Popping up new universes all the time.”But where did this balloon come from?”OK, you’ve got the balloon. The expanding sphere. Only now think of it as a sphere with an infinite radius.”Valentine tried to think of what that would mean. “The surface would be completely flat.”That’s right”And you could never go all the way around it”That’s right, too. Infinitely large. Impossible even to count all the universes that exist on the reality side. And now, starting from the edge, you get on a starship and start heading inward toward the center. The farther in you go, the older everything is. All the old universes back and back. When do you get to the first one?”You don’t” said Valentine. “Not it you’re traveling at a finate rate.”You don’t reach the center of a sphere on infinite radius, if you’re starting at the surface, because no matter how far you go, no matter how quickly, the center, the beginning, is always infinitely far away.”And that’s where the universe began.”

“The choices we’re working with here are a block universe, where past, present and future all coexist simultaneously and everything has already happened; chaos, where anything can happen and nothing can be predicted because we can’t know all the variables; and a Christian universe in which God made everything and it’s all here for a purpose but we have free will anyway.”
