What Schrödinger’s cat REALLY means

Ok, I don’t really believe that a particle can also be a wave. This is because the definition of a particle is a solid. One thing. And one thing cannot suddenly break up and act like a wave. So what has to happen in order for this to make sense? I think that quantum particles are not particles at all. They are something that we see as a particle but it isn’t. So scientists need to revisit them and figure out what it really is, or just accept that it is something different that we will know more about in the future, and give them a new name.
