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

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

The Large Hadron Collider beauty (LHCb) collaboration at CERN has made the first observation of asymmetry in the decay rate of a baryon—a subatomic particle made of three quarks—and that of its antibaryon counterpart. It partly explains why there is matter in the universe.
Matter–antimatter asymmetry is observed in baryon decay
Previous detections of CP violation had been limited to the decay of quark–antiquark pairs. But it’s baryons—particles composed of three quarks—that make up the observable universe.
