Turns out, reality is at odds with itself. But, is it?

Researchers performing a long-awaited experiment created different realities that are irreconcilable, proving that objective facts can be made to exhibit properties that cannot cohere, according to a recent study shared on a preprint server.

Sound confusing? You're not alone in thinking so, as this all involves some pretty complicated physics. But in short, the takeaway is this: Reality is at odds with itself.

Two facts, no ultimate reality
Nobel Prize-winner Eugene Wigner described a thought experiment in 1961 that highlighted an uncommon paradox of quantum mechanics. Specifically, it reveals the strangeness of the universe when two observers, like Wigner and his friend, observe two distinct realities. Since the thought experiment, physicists have used it to explore the very nature of measurement, in addition to the bizarre idea of whether objective facts actually exist or not. This is a pretty crucial feature of science, since empirical inquiry works to establish objective facts.

But if there aren't any facts, how can science presume to describe a real world in the first place?

For decades (and philosophically, much longer), this has served as a great bit for entertaining dinner guests, but Wigner's thought experiment wasn't really anything more than that. Until now.

In 2020, physicists realized that recent quantum technology advances had made it possible to create Wigner's Friend test in a real-world experiment. In essence, we can create different realities, and compare them in a lab to see if they can be reconciled, or cohere, in one system. And researcher Massimiliano Proietti of Heriot-Watt University, Edinburgh, along with a handful of researchers, said they performed this long-awaited experiment for the first time: Creating distinct realities, compare-and-contrasting them, and discovering that they are, in fact, irreconcilable.

articles like that are pure CRAP

all these 'discoveries' are just mathematical fictions.

In a similar vein...




“It is a primitive form of thought that things exist or do not exist.”

Arthur Stanley Eddington​

"All possible universes exist."

Max Tegmark​


It's obvious where all this is leading, but never mind all that science stuff for the moment.

The important thing is this forum needs a musician mascot, and Alina Gingertail is the obvious choice. She is small and cute, and she plays lots of instruments. Also, her last name is "Gingertail". We should have a fan club for her.

It makes me recall a lecture I had in physics about eye witness accounts. Not everyone sees the same thing. It's a universal phenomena. It is almost as if simultaneous differing realities are overlapping during an observed event viewed by many. Yet we blindly go through life believing only one reality is real.
