HAHAHAHAHAHAHA! This is so ridiculous to be best left standing as is.

"Images", huh? Don't let a gang of astrophysicists and particle physicists
gang up on you in a dark alley. They both got so many nasty tricks you'd
never knew what hit you.

What do you think is out there we haven't seen yet? Does it interact
with photons? Does it have mass? Is it observable, even in principle?
Does it largely consist of invisible, pink unicorns, and girls with cups?

Precisely -- we know a lot more about what is out there than what
we've got a few 10 km below our feet -- though you would be surprised
what we do know about that.

Your facts don't even exist. All you've uttered so far is mythical bullshit,
and opinions. You have to do much, much better than that.

Because you're being able to write this message and because there are
stars in the night sky we're in nobody's smart lightcone. Unlike Hollywood
or anime, aliens don't come in cute little starships out of nowhere,
and then leave.

Do you think that thermodynamics is just window-dressing, or optional?
Or that you can arbitrarily relabel observables to fit your crazy-moon
theory, which is a rehash of tired old animism?

Life is about atoms and entropy gradients. There's plenty of atoms
and entropy gradients where you sit. Any inoculated petri dish will
grow radial colonies (temporal snapshots stacked on top of each
other are their light cones), which only stop when they run out of substrate.
You are substrate.

Absolutely not, anthropic effect doubly applies. You will always observe
yourself with the probability of unity, regardless how rare you are, and
you can't observe very well if you never happened, by virtue of my ancestors
eating the primeval muck that would have become your ancestors.

Even reversible logic is not completely reversible. It's also slow,
and 10^23 beings would still need a great many photons, which need to
be reradiated in deep infrared.
Where are these photons? Where is the dark mass, at least?

If you slow your clock cycle too much to keep up with those joneses
who haven't, you're crunchy, and good with ketchup. In general, the
joneses are glowing-red hot, and are between one million to one
billion times faster than you.

That's something what we've been saying the whole time. Fermi's paradoxon isn't.

Man, what a lousy book. I never understood why so many consider it
