Physicists don’t know what the world is like, at bottom
I am not a philosopher of physics, nor do I play one on TV. So everything you are about to read should be taken with a grain of salt. Much better sources are to be found in the writings of Sabine Hossenfelder, or of my friend Jim Baggott, or of “Not Even Wrong” Peter Woit. Stuff by Lee Smolin is also pertinent.
