if we had
never invented radio telescopes) ?
Yes - exactly.
A direct consequence of The Reversal. First comes Mind. Physics and
matter and the 3D holographic farmyard are a long way down the road.
I hope no one is assuming that it requires something as weird as a
"human" to implement consciousness.
Something as basic as a Boltzmann brain would be in principle,
instantly possible in any universe, surely.
Of course Boltzmann brains are notoriously transient, so we're to
think of the universe (or at least pieces of past light cones)
blinking in and out of existence. Or does that take a Boltzmann
brain plus optic nerves and eyes and a Boltzmann telescope?
Yes, not sure why a Boltzmann brain can be said to be basic. Just a
brain, or any computer, or any relative universal will do. A Boltzmann
brain do with a probability near to 0 what UD, or arithmetic do with
a probability one.
BTW, can someone refer to a paper given a reasonably serious
definition of a Boltzmann brain?
