And if so, would it end up as an exercise in over-stimulation, with too much info for our brains to process
If it happened to you now then quite possibly. If it had evolved then highly unlikely.
I’m sure I remember reading that the reason life uses the “visible” part of the spectrum is that radiation in those wavelengths is abundant (e.g. microwaves are pretty rare and don’t reflect well so less informative of the environment), has enough energy to excite electrons (for detection; longer wavelengths are really energy poor, detector would have to be massive and ultra sensitive) but not so much that it would damage the sensing apparatus.
In terms of evolution what would be the advantage of being able to detect these other forms of EM radiation? What would they allow an organism to do better? I’m struggling to think of examples (and it is a bit of a trick question). Maybe if we had evolved some kind of emitter at the same time for radio communication……….
I guess life has evolved to use the most useful forms of EM radiation in our environment.
