Simulation is not an experiment. Everything which involves a probabilistic calculation is not an experiment but a simulation. But go ahead, which experiment confirms existence of antimatter?

Petabytes of data from particle accelerators that only make sense if anti-particles exist. You seem to be operating under the assumption that anti-matter is something weird and exotic. It's not. It's engineering. We use anti-matter in medical devices at your local hospital: https://en.m.wikipedia.org/wiki/Positron_emission_tomography https://en.m.wikipedia.org/wiki/Positron_emission_tomography We're checking to see if our predictions are correct because that is proper science, and it's hard to have a lot of antimatter, but there is basically no reason to doubt it's existence, unless you want to write off all of particle physics. As that is arguably the most solid science we have, you'd basically be writing off all science.

> But go ahead, which experiment confirms existence of antimatter? There are hundreds, but let's provide the first: https://en.wikipedia.org/wiki/Positron https://en.wikipedia.org/wiki/Positron I would have said "supports with evidence" rather than "confirms", in the spirit of falsifiable science. Your argument asks for proof of antimatter, as though science is a religion. But science is a discipline whose purpose is to attempt to falsify ideas, not elevate them to the status of beliefs. Those ideas that resist falsification represent our current understanding of nature, and any of them can be replaced by new theories and new evidence.

There is nothing hinkey about that experiment. However, your confusing modeling with simulation. If I create a scale model to test flood controls it's not 1:1 with reality, but it is constrained by the physical world. Which is what separates experiments from simulation.
