That line of reasoning seems pretty silly given that consciousness is supposed to be much more subtle than electromagnetic fluctuations and omnipresent, but it reminds me of the Tibetan Buddhist tradition where the most difficult practices are only done deep in mountain caves where no light can reach the practitioner. I wouldn't be at all surprised if minimizing cosmic background radiation was a factor in sufficiently subtle inner inquiry.
One of my ancient aliens theories is that the Pyramids are artificial mountain caves.
