It makes a tiny bit of sense to me.

"If we use [unstated first principles] to estimate what energy density should be, it's about 10^94 g/cm^3.
If we use the information content at the Planck scale, it's pretty close -- about 10^90 g/cm^3.

But we actually observe an information density of about 10^-27 g/cm^3.
And if we decrease the resolution from Planck scale voxels to 10 km^3 voxels, we get an information density that equates to 10^-27 g/cm^3.

This is evidence that we are living in a simulation, and the programmers aren't running the universe at Planck scale voxels, but only star sized voxels."

A large mountain of salt needs to be taken with this argument, but it does make sense -- as an argument.

The problem is not the six suns but the constraints on the planet and moon:

* that the planet's orbit be stable over thousands of years. Millions or billions, if you want life to evolve.
* that the moon stay invisible at all times -- never be illuminated enough by any sun to be visible.
* that the moon be wide enough in angular size to eclipse one sun for over a day!

If you read this paper, you see they settled on a moon the same mass as Kalgash but with the density of Saturn! How could such a system possibly arise?

Somewhat similar. Also resembling WISARD, which used RAM like a neural network.

The essential point to think about is that a 1GB RAM can act as a cellular automaton with a billion cells. There's no algorithmic complexity to defeat because there's no algorithm. Of course the harder the problem gets, the more cells you need....

If it's not in the computer, it doesn't exist.

Working...
