“Thinking of the universe as a computer is controversial.”

“I would suggest, merely as a metaphor here, but also as the basis for a scientific program to investigate the computational capacity of the universe, that this is also a reasonable explanation for why the universe is complex.”

“Science consists exactly of those forms of knowledge that can be verified and duplicated by anybody.”

“The amount of information that can be stored by the ultimate laptop, 10 to the 31st bits, is much higher than the 10 to the 10th bits stored on current laptops.”

“At some point, Moore's law will break down.”

“We have a picture for how complexity arises, because if the universe is computationally capable, maybe we shouldn't be so surprised that things are so entirely out of control.”

“In this metaphor we actually have a picture of the computational universe, a metaphor which I hope to make scientifically precise as part of a research program.”

“Another feature that everybody notices about the universe is that it's complex.”

“Merely by existing and evolving in time - by existing - any physical system registers information, and by evolving in time it transforms or processes that information.”

“Computers are famous for being able to do complicated things starting from simple programs.”

“Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there.”

“According to the standard model billions of years ago some little quantum fluctuation, perhaps a slightly lower density of matter, maybe right where we're sitting right now, caused our galaxy to start collapsing around here.”

“Similarly, another famous little quantum fluctuation that programs you is the exact configuration of your DNA.”

“In order to figure out how to make atoms compute, you have to learn how to speak their language and to understand how they process information under normal circumstances.”

“Nothing in life is certain except death, taxes and the second law of thermodynamics.”

“If you take a more Darwinian point of view the dynamics of the universe are such that as the universe evolved in time, complex systems arose out of the natural dynamics of the universe.”

“It's also a reasonable scientific program to look at the dynamics of the standard model and to try to prove from that dynamics that it is computationally capable.”

“If you wanted to build the most powerful computer you could, you can't do better than including everything in the universe that's potentially available.”

“One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?”

“A claim that event horizons exist is like someone's claim to be immortal: You would have to wait until the end of time to confirm the claim.”
