The World of Senses

Dog whistles got me thinking! So, to better understand things, I’ve done a little research on four of our five senses and what our bodies are able to perceive.
The dog whistles have a higher pitch than the human ear can hear. You can learn about that more by clicking here, but lets ponder this fact for a moment.  A whistle that we can see and touch but cannot hear when we blow into it.  To some it would seem that no sound exists at all.  However, it’s been proven that it produces a sound in a pitch that does not resonate in the human ear.  Consider also animals in the wild and their own keen hearing, allowing them to alert them of predators and to help them find prey.
Dogs also have the innate ability to smell out certain items or people.  The dogs sense of smell is measured at approximately 100, 000 times that of humans.  One hundred THOUSAND times that of humans.
Humans have better sight than a dog.  As many humans would agree, sight is amazing and yet the only things our eyes can do is detect light.  Cats and other animals have the ability to see in the dark because of the layout that projects the light that illuminates the retina.  The Mantis Shrimp has the best eyesight, it is the only known animal with hyperspectral (electromagnetic imaging) color vision and can perceive polarized lighting. Their eyesight is keener than all birds of prey.
The human touch is determined by sensors in our bodies.  We have sensitivities to heat, cold, pain, itching, and pressure.  These sensors are mainly found in the skin but can also be found in joints, and muscles.  It’s also interesting to note that their have been cases where people have been born without this ability!  Such a condition is called “Congenital Insensitivity to Pain” (CIP) and is the inability to feel pain however can still feel discriminative touch (but have been known to be unable to feel temperatures as well).  In some cases it’s caused by an over production of endorphins in the brain, in others there is a mutation that takes place in the protein NaV1.7… if I understand correctly.
So let’s return back to the dog whistle for a moment.  How do we know that it makes a sound?  Does the fact that we can’t hear the whistle mean it doesn’t exist?  No.  Because of our technological advancement, we have learned that there are things all around us that we know are there by their effects, despite our ability to sense them with one or more of our senses.  For instance, we know that wind exists because it moves trees, we know gravity exists because it keeps our feet on the ground, we know about some sounds that we cannot hear because they cause visual vibrations, etc.  We can’t see these and yet we believe – and know – they are there.
Is it possible that we have not yet learned of other things that we can’t see despite the effects that surround us?  If there are things we can’t see, touch, taste, or hear, but so far have been proven to exist, isn’t it possible that there are things that we’ve not yet proven due to lack of technology?  Isn’t it possible that there is a God – a being we cannot yet see, hear, or touch but have not been able to prove due to lack of ability?
Isn’t it possible?
Scientifically? Yes.
