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

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

Indeed, as the above calculation indicates, to take full advantage of the memory space available, the ultimate laptop must turn all its matter into energy.

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.

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.

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.

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

All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.

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.

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

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.

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.

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?

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.

Something else has happened with computers.

Of course, one way of thinking about all of life and civilization is as being about how the world registers and processes information. Certainly that's what sex is about; that's what history is about.

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.

Thinking of the universe as a computer is controversial.

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

I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.

Every physical system registers information, and just by evolving in time, by doing its thing, it changes that information, transforms that information, or, if you like, processes that information.

There are considerable advantages to using many degrees of freedom to store information, stability and controllability being perhaps the most important.

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.

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.

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

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

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.

What's happened with society is that we have created these devices, computers, which already can register and process huge amounts of information, which is a significant fraction of the amount of information that human beings themselves, as a species, can process.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

Near the sun is the center of the universe.

There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history.

If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?

The rockets and the satellites, spaceships that we're creating now, we're pollinating the universe.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

The universe is made of stories, not of atoms.

Be universal in your love. You will see the universe to be the picture of your own being.

The natural state of motherhood is unselfishness. When you become a mother, you are no longer the center of your own universe. You relinquish that position to your children.

This universe can very well be expressed in words and syllables which are not those of one's mother tongue.

We can certainly go further than cats, but why should it be that our brains are somehow so suited to the universe that our brains will be able to understand the deepest workings?

The earth is a tremendous gift. There is nothing else like it in the known universe. I want to leave it the way I found it.

Science cannot tell theology how to construct a doctrine of creation, but you can't construct a doctrine of creation without taking account of the age of the universe and the evolutionary character of cosmic history.

As we get past our superficial material wants and instant gratification we connect to a deeper part of ourselves, as well as to others, and the universe.

Today we no longer regard the universe as the cause of our own undeserved troubles but perhaps, on the contrary, as the last refuge from the mismanagement of our earthly affairs.

The realm of immediate or personal knowledge is a narrow circle in which these bodies move; the realm of knowledge derived through faith is as wide as the universe, and old as eternity.

The author, in his work, must be like God in the Universe, present everywhere and visible nowhere.

The universe as we know it is a joint product of the observer and the observed.

A broad margin of leisure is as beautiful in a man's life as in a book. Haste makes waste, no less in life than in housekeeping. Keep the time, observe the hours of the universe, not of the cars.

If it's true that our species is alone in the universe, then I'd have to say the universe aimed rather low and settled for very little.
