And that would make the idea of that super universe superfluous. By
applying occam's razor the answer is therefore: yes. Surprising isn't it?

Not necessarily. Only in this one particular case. The super-universe might
be controlling the probabilities, for example, or the constants like c or q.

Only if these constants are free variables. I don't know if they are.
Actually for many constants we don't know why they have a specific value
(or even if they are constants at all). It may turn out that all of them
can be computed without reference to any measurements or that there are
a few free variables in this universe or perhaps that some depend on the
time since the big bang. Only if there are true free variables among the
constants you super universe could exist. Or actually if that is not the
case we might still find another way that that super universe might
exist. Sort of like finding a way that a god might still have an
influence this universe.

Sure. I'm sure none of us know enough cosmology to rule out whether this
universe could be simulated.
Heck, *you* could be simulated and I and all the scientists you've ever
heard of could be just part of the simulation.

Yep. I'll still recommend Calculating God by Robert Sawyer. A wonderfully
fun bit of fiction.

I’ll give that a try since you recommend it. I take it you’ve read
Simulacron 3 (Counterfeit World in the UK) by Daniel F. Galouye? Or The
Tunnel Under the World by Frederik Pohl?

The second sounds familiar. The first doesn't. Calculating God isn't abou
t
the universe being a simulation, tho.

It was written in 1964 so you may have missed it.

Neither it is but what the heck! I could do with finding a new author.
And the synopsis looks OK.

I am looking for one even as we speak. :-) (It certainly explains why it's
not on the Kindle. ;-)

As for that, Greg Egan is my favorite hard SF writer right now. Pretty much
everything he has written is very, very thought provoking. I also am quite
enjoying the Neal Asher stories, especially the Spatterjay series.

I've got a pdf copy in my collection if you can't find it (676 k).

I've read some Greg Egan, he is good. I don't think I've read Asher, tho'.

Start with The Skinner. That's my favorite of the bunch. Lots of interesting
philosophy amongst all the plot.
(I did have to giggle at some of the weapons, like the anti-photon weapon,
or the full-spectrum laser.)
