P.S.
In response to your statement "and things can exist without taking space (for instance: light)."
Light is not a thing. It is a wave within the electro magnetic spectrum. To say light is a thing would be like saying heat is a thing as heat is infrared light. Rather it is a state of being. Waves exist in a medium and the medium is the thing or things.
Waves also take up space. They are measurable. We can measure the difference between blue and red. We measure the frequency of waves in a medium. To say light (waves) are a thing is ridiculous. Even more ridiculous is to say we can not measure light (waves).
Please consider what I have said with an open mind. I look forward to your response.
Light is also a particle (photon). This is an experimental fact very well understood theoretically. This was demonstrated in the beginning of the 20th century, with the development of quantum mechanics.
"Theory" has a very well defined meaning in science, and it is not what you wrote.
In addition, one of the core ideas in quantum mechanics (how can it be a lie when a huge fraction of the world economy relies on its properties?) is the duality between waves and particles. See my other reply and check out the double-slit experiment. This is the proof.
Sorry but I cannot. You have not backed up any of your claims, and you simply mentioned that everything we have learned during the last 300 years consisted of lies (despite tons of experiments and applications). This is not how science works. We have experiments, data, and people (remark: not only people).
You cannot throw away previous knowledge without a reason. If you want to replace the currently admitted paradigm by something else, the something else should at least explain all observations made so far as much as the currently admitted idea. Without this, we don't gain, but we lose understanding, This is how novel ideas emerge.
Both. We have experimental data, measurements or facts. Then you have a theoretical framework that can be used to derive predictions for the observations in the past, current and future experiments. This theory can of course be falsified (that's part of the definition of a theory).
So far, the Standard Model of particle physics has not been falsified. It is therefore the currently admitted paradigm. Throwing away theory and data without a good reason makes no sense. Claiming they consist of a 300-year conspiracy also requires a proof, that has not been presented.
I was "not told anything". I analysed the findings and developments of the last hundreds years, and learned from there, taking as proofs what were proofs. Ignoring them would just be fooling ourselves...
You can check out any textbook or online lecture on quantum mechanics. The double slit experiment may be the right place to begin with. You may even start with the wikipedia page and the references therein. It is very well explained.
