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....

An Ada exception is when a routine gets in trouble and says 'Beam me up, Scotty'.

Working...
