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.

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

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

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

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.

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.

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.

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.

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?

Seth Lloyd
Seth Lloyd

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.

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.

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.

Something else has happened with computers.

Seth Lloyd
Seth Lloyd

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.

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

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

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.

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

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.

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.
