these quuestions pop up in my head n bother me.... anybody got any answers? vibgyor is the range of colours we can see. do we have colours beyond the range, which we cannot see? can we have some new colours? can we modify the functions of the human eye so that it perceives the wavelenghts which our present eye cant perceive? do animals also see the same colours as we do? if bats and dolphins can hear thigns that humans dont, can they see colours that we dont? similarly, can we scientifically modify our ears to hear what dogs, dolphins n bats hear?? imagine we can hear more bassy bass....wont that be cool? sound is energy. can we use sounds of high frequency to create heat, or light? if sounds are used as fuel, wont that be just the ultimatest thing on earth? can we equate wavelengths of sound, smell, n light? can we smell monalisa, see hotel california or listen to a big mac? what would stairway to heaven look like if it were a painting? or how would it smell if were an edible? ????
