> the wave is something separate from the object but is related to it. This is a common idea in Bohmian epistemology, but, speaking as a professional physicist, I don't think most physicists would hold this position. The wave is the object, the object is the wave. "Particle/wave duality" or whatever is just bad language for "a quantum mechanical thing" I think the point of saying it "exists at two places at once" is…

The issue then becomes the difficulty of enjoying a Bohmian lifestyle when trying to formulate a relativistic, many-body, QFT.

Finally they can get started on quantum superposition human teleporters. I want to see Neptune but I want to be home by dinner.

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…

To go further, I have a colleague who says there are actually no particles, only waves interacting with other waves. I am trying to get him to make a proper thesis out of this but he is busy trying to earn money to support his family. If there are any theories about this, please link them in the thread! It sort of resonates with what Richard Feynman has been demonstrating in some of his lectures but I have not been a…

That is a truly splendid turn of phrase.

Thank you! Rant: Not linking to the source article is a crime conmited by many outlets trying to report on science. I do not understand that practice. It is even worse when the researcher's institution does this in a public press release (MIT is consistently guilty of this). Are these people afraid that their watered down "explanations" are so wromg that even a cursory glance over the paper will show this? Some news…

It doesn't need to be a link. A citation at the bottom of the article would suffice.

Damn, it wasn't so easy to find the article, because TFA doesn't explicitly provide author names, even. But the link in the image title led to Fein et al. (2019).[0] So what I'm curious about is how far apart those "Two Places at Once" are. And if I'm understanding Fig. 2 correctly, it's large . That is ... > Fig. 2 | interference data. a, Counts as a function of the transverse position of the third grating with a si…

Dunno if it was a link when you looked, but "Nature Physics" in the third paragraph links directly to the paper and bypasses the Nature paywall with some sort of referer link.

Soon, things that are today considered fantasy and disregarded as mysticism will become science facts, just as electricity and magnetism were alien things a century ago. In the end we will realize that every myth comes from a true source. Everything can be made to be, once you put enough energy to make it manifested; I have absolutely no doubt in my mind about this, since I've seen and read things that are well beyond from what is common knowledge;

It s a PROBABILITY of being at the same position and not a position per say.

I've been trying to get it to catch on, to little avail! Maybe I need to render it as Boh[e]mian? I feel like that gives it away!
