It raises some intriguing questions/facts about quantum physics.
Some of which are quite fascinating or disturbing, depending on how you look at it.
It's got timestamps so you can pick any of the topics that are of interest.
I think our scientist friends have gotten so smart they are stupid. That may sound like malarkey, but consider the Wigner friend.
So you have a observer in a lab measuring a atom, he finds that it is spin up. Wigner is outside the lab, he has no clue what the spin is. Since he didn't measure it. That doesn't mean the atom is still in superposition, Wigner just doesn't know what the spin is. If he walks in the lab and ask the guy what the spin is, then he has the information, that he didn't have before.
Even if he walks in the lab ask the guy for the spin and he says it's up, then then Wigner measures it and the spin is down. That doesn't mean both are in to different universes. It could mean the atom just changed position.
The same thing with Schrodinger's cat. If you change the poison to dynamite or acid. You will definitively know if the atom decayed. Since the acid would eat through the box, or the dynamite would deform the box, or blow it apart.
If you made a box that could house the cat for more than the lifespan of the cat assuring it had food, water,and air. 35 years later when you open the box, you will not find a live cat, even if the atom never decayed. The cat was never in a superposition.
I think quantum mechanics only shows, the universe is not up and up. Not that everyone has there own universe. But we all do have our own reality.
I couldn't watch it all, do to the guys seizure inducing CGI. And I play a lot of video games and have never felt like I did while watching that.
That's my take, I could be completely wrong.
