Hey I'm there too ,,beside urs next chair

I am there already

Right

He could give Arnold physics "advices"

Great All 🙏🇱🇰❤💛

Well, the journal Scientific American has an interesting article about it, that's fairly accessible to the non-physicist. Just Google up "Scientific American - the universe is not locally real" and you should be able to get it. Zeilinger's work, in particular, represents a challenge to the philosophical position of Local Realism - roughly, (1) the notion that we exist in a physical universe that exists and has characteristics on its own, independent of our conscious experience/perceptions of it, and (2) the objects can only be influenced by things in their immediate surroundings, and not by something on the other side of the galaxy or universe, for example. We all assume this of course, in our everyday lives. The three scientists honored, including Zeilinger, who has gone the furthest in this regard, have together seemingly disproven Local Realism. According to the article, many feel that their Noble Prize is long overdue. These experiments, and those of others, undercut the notion that we live in real world of physical of time-space. For example, Zeilinger points out near the end of his talk “when you look at the predictions of quantum mechanics for multi-particle entanglement - you can have one measurement here, one there, one earlier, one later - these predictions are completely independent of the relative arrangement of these measurements in space and time.” In other words, they tell us something about the role of space and time - there is no role at all.” Interestingly, it has demonstrated in the last 10 or 20 years in so-called “delayed choice” experiments, such as those mentioned by Zeilinger, that particles seem able to go back in time and change what they did earlier to comport with what humans decide about what and how to measure, later. People use the phrase “go back in time” often metaphorically - what is really being demonstrated is that our experience of linear time is illusory. Zeilinger seems to say at the end of his talk that he favors the idea that what lies at the foundation of our "reality" is not physical stuff, i.e., “matter”, but information - information that constructs the world that we experience. There is a growing segment of physics called "Digital Physics" that holds that we live - if not in a simulation per se, then in something like a simulation, with information at the foundation of it. I don’t know if Zeilinger goes that far, but his views seem to be in that direction. Zeilinger has been overseeing mind-blowing experiments that are changing the way we view our reality. And he’s a really likable human being, too.
