I appologize if my question was unclear. I only used the blind person as an example to relate what I wanted to say because I found it very difficult to find the words to describe a question about something that we might, if such a thing exists, be unaware of, due to a lack of ability to sense and percieve it. And would we even be able to determine if any number of these such things do exists, which might be a critical part of the structure of physics.
Oh and definitely not too serious to joke.
Aren't physics and philosohy "together" as one at all times, except when broken down into letters, words,numbers and symbols only so we can communicate what we perceive, with one another. I see how this is related" to philosophy, but in my opinion physics can be summed up with; observations, measurements, comparisons, and communication, which are only done with the use of our senses. Senses are essential in physics, and all else. I am simply exploring if it is possible to prove more "senses" could exist. -I am truly sorry to have directed a thread to the wrong forum, and I will check with PF next time to assure proper directing.
Measurements are compared physical quantities. All senses are measureable. Comparing physical quantities would be the only way we would be able to discover the unknown sense(s). Any sense discovered, if able to be and done, would be measurable.
And this subject might be "beyond" PF, but I was simply posting this topic for a good disussion which might help progress the study of physics, and/or help me understand more about physics. I dont need, or expect an answer. So, all thoughts and opinions are, of course, welcome.
