The answer is, of course, no. As Nigel explains.
Is matter conscious? app.thenewworld.co.uk/story/144378...
Is the universe conscious? Philip Pullman thinks so…
It’s fun to entertain the possibility of panpsychism – that all the physical things around you have some level of experience. But that doesn’t mean it’s how reality works

"Baggott’s book is a masterpiece that combines depth with clarity and comprehensiveness with readability,” says renowned historian of physics Helge Kragh in his review of my new book ‘Discordance’. 😳 www.nature.com/articles/d41...
Why we still don’t understand the Universe — even after a century of dispute
Despite huge breakthroughs, astronomers still can’t agree on what the cosmos is made of, much less how it came to be. A fresh account delves into the reasons.

The Cepheid found in Andromeda by Hubble had been discovered earlier by Milton Humason. But when he showed the marked image to Harlow Shapley - who had argued that the Milky Way *is* the entire universe - Shapley erased the marks.
VAR!
In the early morning hours #OTD in 1923, Edwin Hubble took a photo plate of M31 that showed a Cepheid variable star.
Using Henrietta Swan Leavitt’s distance-luminosity relationship, Hubble concluded that M31 is another galaxy outside the Milky Way. 🧪 🔭 ⚛️

Although it tells a remarkable story, the current Big Bang theory leaves us with many unanswered questions, and recent astronomical observations threaten to undermine it completely. @jimbaggott.bsky.social
