What if there are no laws of physics?
Jo says- When physicists investigate the very smallest components of reality – atoms and subatomic particles – they famously find all sorts of things that make no sense. Particles can apparently be in different places at once, and they have different properties depending on how we measure them. Spooky effects seem to act instantaneously, across vast distances. The decisions we make can even alter journeys that particles have already made.
Researchers have come up with different interpretations for what these weird results might mean. Maybe mysterious waves we can’t measure are guiding the course of the entire universe. Or maybe there are countless parallel universes, hosting different versions of ourselves...
What if none of these ideas is wild enough? My guest in this episode, quantum physicist Chris Fuchs from the University of Massachusetts, thinks physicists are still being boxed in by their assumptions about reality. Chris has pioneered a new interpretation of quantum mechanics, called QBism, which says that the probabilities and predictions of quantum physics were never describing physical entities out there in the world. Instead, he says, they are telling us about… us.
I recently came across this fascinating podcast series by the writer and journalist Dr Jo Marchant
Jo is a New York Times bestselling author and speaker. Her writing explores the nature of humanity and our universe, from the mind-body connection to the mysteries of past civilisations and the awe-inspiring night sky.
This episode is
Her podcast - Where the wild thoughts are - explores science on the edge - Here's what she says of the podcast: "We’re pushing boundaries from cosmology and quantum physics to neuroscience, archaeology and ecology. Each week, Jo interviews scientists who are challenging our assumptions, stretching our minds, and changing how we see the world."
