1. Particles can go back in time and do stuff?

2. Has quantum erasers been done using electrons or molecules like buckyball?

3. Does this experiment prove that particles are not really particles but just related to the wavy field that can form interference?

4. Does this prove that particles don't travel in between but only the detection event is important?

5. What's the explanation why if which-path information is suppressed, intereference form, does this has to do with decoherence?

6. Or is this more of information theory that any time which path information is known, it automatically hide the interference without regards to decoherence or others? In other words, it's a rule of nature that this must be done.. but how is the rule implemented? Or what is the corresponding symmetry of nature preserved for this rule if there is any?

Quantum erasers and stuff can give us a clue about what really are particles and what would be the correct interpretations. Heck, if there are no particles at all, then most interpretations can be done away with. But we know particles like buckyball exist. But how can buckyballs pull such stunts as quantum eraser? Does it really go back in time or are buckyballs really not there before detection? What's a rational explanation for the quantum eraser mystery? I can't understand how HUP (Heisenberg Uncertainty Principle) can solve it. Can it? How. Please explain. Thanks.
