You know that humanity's science and technology has been developed primarily as a result of our sight. We saw the sun going round us and realized its periodicity. And hence we got day and night. And slowly developed the geocentric theory and with more observations, got the heliocentric theory. Then came 1400s with Newton etc., who studied light and it's splitting and then there was a lot more study of EM waves which though we could not see with the naked eye, we realized that they were there because of an extension of visible light and because of their effects on various photographic plates etc. And so we studied all science using eyesight. Be it quantum mechanics, or whatever. All based on Electro magnetic theory. The question is this. What would science be like, if sight was not present? Note; do not consider a blind man situation, but an organism with more advanced senses like touch, sound etc. (say a smart bat). I got this doubt because in all science fiction stories, aliens are shown having pretty much the same technology we do or hope to do. What if their evolution skipped sight for a preferable sense which is more useful in their environment?
