No matter how many words/gestures one uses to describe his/her qualia, I won't be able to know what it was like for him/her to experience his/her qualia. I know what it was like for me to experience my qualia, simply because I can remember what it was like for me to experience my qualia. So, to me, there is no evidence that anyone else can experience his/her qualia. So, one can't prove to others that he/she can experience his/her qualia. One can’t (use any words/gestures to) prove to others that he/she can experience his/her qualia. "What is it like to be a bat?" When I imagine what it is like to be a bat, I'm actually imagining that I am the bat. Or in other words, I’m imagining that the bat is me. When I imagine that a bat is me, I’m actually imagining that a homunculus is sitting inside the bat’s body. What does this mean? What is that homunculus? That homunculus is a “clone” of me! That homunculus is another “me”! So, when I imagine that a bat is me, I’m actually imagining that I am sitting inside the bat’s body. So, the question “What is it like to be a bat?” is actually equivalent to the question “What is it like to be me?” or the question “If I sit inside a bat’s body (and control/feel the bat’s body) as the bat itself, what is it like to be me (under that situation)?”. The question “What is it like to be me?” is actually equivalent to the question “If I sit inside a human’s body (and control/feel the human’s body) as the human himself, what is it like to be me (under that situation)?” or the question “If I sit inside my body (and control/feel my body) as myself, what is it like to be me (under that situation)?”. Regarding its usage, the term “qualia” is equivalent to “(subjective) feeling” and “(subjective) experience”. The term “qualia” draws our attention to the ontological question “What is the nature of (subjective) feeling/experience?”. The term “qualia” urges us to think about the ontological question “What is the nature of (subjective) feeling/experience?” endlessly.

In order to describe my findings/conclusions systematically, a new semantic system (i.e., a new language) has to be intentionally defined by the present article. Humans are limited in what they know by the technical limitation of their cortical language network. A reality is a situation model (SM). For example, the conventionally-called “physical reality” around my conventionally-called “physical body” is actually a “geometric” SM of my brain. The universe is an autonomous objective parallel computing automaton which evolves by itself automatically/unintentionally – wave-particle duality and Heisenberg’s uncertainty principle can be explained under this “first-order” SM of my brain. Each elementary particle (as a building block of the universe) is an autonomous mathematical entity itself (i.e., a thing in itself). If we are happy to accept randomness, it is obviously possible that all other worlds in the many-worlds interpretation do not exist objectively. The conventionally-called “space” does not exist objectively. “Time” and “matter” are not physical. Consciousness is the subjective-form (aka quale) of the mathematical models (of the objective universe) which are intracorporeally/subjectively used by the control logic of a Turing machine’s program objectively-fatedly. A Turing machine’s consciousness or deliberate decisions/choices should not be able to actually/objectively change/control/drive the (autonomous or objectively-fated) world line of any elementary particle within this world. Besides the Schrodinger equation (or its real-world counterpart) which is a valid/correct/factual causality of the universe, every other causality (of the universe) is either invalid/incorrect/counterfactual or can be proved by deductive inference based on the Schrodinger equation only. If the “loop quantum gravity” theory is correct, time/space does not actually/objectively exist in the objective-evolution of the objective-reality, or in other words, we should not use the subjective/mental concept of “time”, “state” or “space” to describe/imagine the objective-evolution of the universe.
