I think that evidence for existance of particles is pretty old and should be reconsidered. I think we 8should more carefully treat the data that convinced physicists that matter is particles, before they knew matter is a wave. Maybe it's counter productive to percieve matter as made of particles with particle qualities (what are those? pointlike, with specific (even if unmeasurable) momentum, position energy).

Maybe momentum, position and energy is not something 'particles' have all the time. Maybe it's just something they manifest only while interacting.

Please correct me where I am wrong, I have only studied quantum physics as a hobby. I dislike this description of things existing in two places at once, this is because I believe that objects exist in one place, then they move to the next place. The interference pattern only highlights the probability of where the particle will be when it's next observed, or "where it moved to". The object does not interfere with its…

The problem you are having (I think) is this damned phraseology we have grown accustomed to "in two places at once". That's not the proper way to think about it. Anything and everything can be in a superposition of location and state where the location or state is not determined until forced to by some measurement/interaction. The universe if you will is not determined. It's in a superposition of states and positions…

You are absolutely right. I personally have adopten the BSM-SG (developed by Dr. Stoyan Sarg) model which puts very strict limits on the superposition concept. No particle is ever at two places at once nor does it jump around. The model is however much much finer in it's structural organization. A neutrino for example is quite a large object from the BSM perspective. When a photon for example pumps the CL space volume occupied by a electron orbit, there is a limited time in which the CL is pumped in a way that the photon is existing as a complete structure anymore, but the electron is not yet pushed to a higher orbit. Chapter 7 in the book goes in very much detail of this.

This uncertainty is very limited for is existence in time and very limited which processes can implement such uncertainties. From the BSM perspective, looking at the experimental setup, I can not really see, how this will prove uncertainty.

Earlier quoted context omitted.

From a quantummechanic standpoint its wrong to say, that its at two places at once. I really dont like the Headline. Superposition means, that it didnt decide for one of the two possible states, and so these both exist in superposition.

Can you say it’s moving between two places with an infinite frequency?

No not really, only when you observe the particle, the location is determined. ANd at this point it behaves like a localised single particle.
