The invisible

We exist in a reality where we have evolved to sense certain input, whereas, most stuff is invisible. For a being to truly see the world around them, they would need to be aware of all the happenings and must project existence of certain phenomenon by visible observations. We have came a long way observing and building the knowledge that exists, subject to human perception, for e.g. Magnetic field:

How does the magnetic field exists in space? is it the property of space itself, like a space full of liquid-like stuff of magnetic field.
There is some stuff, at the point at which they become definitions in science, and their existence is taken for granted.
I can say with confidence that the textbook science after 1000 years would be significantly different in interpretation, by human mind and by AI. One thing is to write things down and read them in text without ever actually knowing what exactly happened, and another is to actually simulate them in the human mind. Human mind is grown naturally, but with rapid development on algorithms, and vast clear understanding may rewire our brain itself in the form of a computer. It may put our brains to solve problems with efficient mindset. The quality which is called skill, is engraved in the brains, however, if one would actually see its form in the brain, one may begin to put such imaginative concepts as a part of reality in this world. Life is meant to thrive, one may be curious enough to see if there is another angle at which life grows naturally in the universe, rather than just the carbon form. Much like an software compiler with fix design, the universe is formed from fixed constituents which form the basis, distributed in space, flowing as per time, existing as an mathematical object to the definitions of science interpreted by humans, in space.
