We can certainly detect ourselves, and it is not impossible in principle for a alien in a distant galaxy to detect us, and that is very different from your silly phantom computations that pure numbers are suposed to be able to perform. > *It is like the other side of the moon before we built rocket. * > Nobody ever said there was a philosophical problem in observing the far side of the moon, it was always just a matter of engineering, but no amount of engineering can make your ridiculous phantom calculations real. If they existed it would be possible in principle to count the number of angels that were sitting on the head of a pin, but your non-material Turing Machine is hopeless.
