It is such a circular kind of thinking. It is a circular way of seeing things that I often find myself following to define and describe what is real. All I know, all I have to go on is what I perceive with my senses. My senses alone tell me what exists. My senses connect me to what I determine is real. It is often a circuitous route, but it always comes back to what my senses tell me, what I learn through my senses. It is a circle.
It is typical that physicists fabricate laws to explain and define reality. Those laws and definitions have constantly changed as perceptions have changed. Even those explanations and laws are based on sensory observations.
For me, the laws of physics describe what is real and project what can be. They all are ultimately based on sensory experience, on what senses have perceived. It is a circular way of thinking that I say what is real only based on what my senses pick up. Anything else that is real is beyond my knowing. It would be foolish to say that nothing exists outside my bubble of perception and the thinking based on it.
The tools that physicists use all are extensions of the senses. Even the tools that look into what happens inside atoms and how small particles perform convert it all into sensory data. All my knowledge is based on this way of gathering information.
It makes no sense to me that some people limit reality to what they can perceive with the senses. It is a circular way of thinking. Of course, their reality is limited to what their senses perceive because that is how they define what is real. That is a circle.
