Alpha when you test the tangible substance using experiments you are using your eyes to see what the results are of those experiments. That means that is also visual.

Alpha when you test the tangible substance using experiments you are using your eyes to see what the results are of those experiments. That means that is also visual. You are a hypocrite. And cant answer that question. Ever.

Already have, you don't understand the difference between visual and physical. If a blind person was tesing the substance the physics remain th same.

Should be easy for you then to provide a physical practical demonstration of a standing body of water with the surface naturally bending.
