Is There Even Such a Thing as a Particle?

The notion of particle is already relativistic. By saying there is a particle, that already implies some way in which you're probing that thing that's there. But then the question sort of arises, well, if it's not a particle and it'm not a wave, what is i what is it there until we probe it? And a to understand that, go check out my a two part series a called a quantum mechanics d bunks materialism,. where i go into a lot of depth plaining those sorts of things.
