"if i cant see it, feel it, hear it,taste it, or touch it, then it doesn't exist"This
really rings a bell to me because I used to think
EXACTLY this way, then one day something happened
and I soon realized that there was a
BIG problem.
Humans are visual beings by design, now more
than ever in this colorful world full of movement,
screens and advertising we live in, but there is a
huge problem and I'll explain it with the best
example I can think of right now:
Stacked-up, all the light wavelengths in the
physical universe would be as tall as the empire
state building, but if one takes into account the
visual
range of the human eye this would not
even measure the thickness of a sheet of paper
and this does not mean that those other 102 floors
do not exist, "see" the problem?
Also realized that all of our senses are just electric
impulses translated into things and feelings by our brain
and that humans are actually pretty ill equipped in the
5 senses department to begin with.
** Just a few examples:
Vision (Natural light) A cat has 400,000 sense organ cells per
square millimeter catch light and movement, a hawk 1 million.
Aural (Sound) Humans have a hearing range of 20-20,000 Hz.
A bat of 2,000-110,000, a beluga whale from 1,000-123,000Hz.
A porpoise can hear up to 150,000 Hz and a common mouse to 90k.
Ecolocation (Sonar) Whales, dolphins, bats and some
shrews use ecolocation to navigate their surroundings.
Infrared Vision (Radiation) Rattlesnakes and other pit
vipers use their eyes to see during the day, but at night
they use infrared sensory organs to detect and hunt
warm-blooded prey.
Ultra Violet Many fish, amphibians, reptiles, birds,
insects and some mammals have ultraviolet vision, but
not humans.
Electric Sense Electric eels, some rays have modified
muscle cells that can shock and sometimes kill their prey.
Other fish and frogs use weaker electric fields to navigate.
Bio-electric Sharks have a semiconductor gel that
can sense bioelectric fields of prey and other animals in
seawater using an extraordinary system of sense organs
called ampullae of Lorenzini.
Magnetic Sense A number of animals that have deposits
of magnetite in their nervous systems are able to sense
the earth's magnetic field (north) and navigate accordingly.
