The world is not a quantum wave function - Why reality is non-local and the wave function isn't real
https://iai.tv/articles/the-world-is-not-a-quantum-wave-function-auid-3096?_auid=2020
INTRO: The world of quantum physics is a very different world from the day-to-day reality we experience. In the quantum world, interactions across vast distances can occur, non-local interactions. Some quantum ontologies try to explain non-locality using a high-dimensional wave function. But Professor of Philosophy of Science, Valia Allori argues we need to bring our theories back down to three-dimensional Earth, albeit with the inevitable sacrifice of a local universe...

Does the multiverse explain our fundamental constants? (cosmology, philosophy of science)
https://bigthink.com/starts-with-a-bang/multiverse-explain-fundamental-constants/
KEY POINTS: In our Universe, the values of our fundamental constants dictate the behavior of nature: the strengths of the different forces, the masses of the fundamental particles, the value of the cosmological constant and more. In some cases, these values could be vastly different and our Universe would only be slightly altered; in other instances, even modest differences would lead to an unrecognizable reality. So where do the values of these fundamental constants come from? Is there a physical mechanism or explanation behind them? One possible solution lies in bubble universes from inflation, but is that actually correct? (MORE - details)

‘Next-level’ chaos traces the true limit of predictability
https://www.quantamagazine.org/next-level-chaos-traces-the-true-limit-of-predictability-20250307/
EXCERPTS: The French scholar Pierre-Simon Laplace crisply articulated his expectation that the universe was fully knowable in 1814, asserting that a sufficiently clever “demon” could predict the entire future given a complete knowledge of the present...
One blow came in the early 1900s with the discovery of quantum mechanics. [...] Another came later that century, when physicists realized how much “chaotic” systems amplified any uncertainties...
In recent years, a third limitation has been percolating through physics — in some ways the most dramatic yet. [...] Known as undecidability, it goes beyond chaos. Even a demon with perfect knowledge of a system’s state would be unable to fully grasp its future... (MORE - details)

Is climate persuasion a fool’s errand?
https://www.anthropocenemagazine.org/2025/03/is-climate-persuasion-a-fools-errand/
INTRO: It happens every day. A friend or colleague talks enthusiastically about buying a new gas car, or shivers theatrically on a chilly day and says: “So much for global warming.” Now you’re faced with a choice. Do you engage them with facts and arguments or just smile neutrally and change the subject?
Climate change, perhaps, used to be a topic where reasoned discussion was possible, particularly if people were lacking basic facts about atmospheric chemistry and the scale of fossil fuel use. These days, it can be more of a conversational third rail than religion or sport.
Here we tackle two intertwined questions. First, there’s now been two decades of research on environmental psychology. What have we learned about changing people’s minds on climate? But there’s a second, larger, question looming in the background: Does moving towards a decarbonized planet need everyone to buy into a science-based view anyway? (MORE - details)
