The guy who made the video eliminated the cat and superposition. I already stated Hugh Everett was mocked and laughed at so hard, he quit his job and went into another industry. He was a better mathematician than physicist. He continued drinking and died early.
No. Not any way. This is for example a way Erwin Schrödinger showed:
In general: The way is physical research. The ideas of Schröderinger are taken serios, because he is an excellent scientist.
So was Everett. Schrodinger and Schrodinger's equation is on my side, remember? I said I liked his
thought experiment. The wave exists as
potential energy like the electron can be everywhere it can be. It is realized or the energy is realized when it is measured. Now, Everett, he took Schrodinger's equation and manipulated it with his mathematics to fit his wacky idea. You and Everett are on the same side.
I can only explain it using Schrodinger's thought experiment; It exists in our thoughts. It is potential energy that is there, i.e. the photon energy. We just don't know where it goes through the right or left slit until it is observed. Then the energy is real; It is released and we see it. What if you had a light reading device? It would record it. That is observable and demonstrable.
You don't read what someone says to you, isn't it? Otherwise you would know now that potential energy is a real energy.
Prove it.
You can't even measure the energy; That's such a lame argument because it proves my point

. Now, you're being mocked like Everett

.
It is "spooky" because something is wrong with our perception of space and time.
Go on explain more. What's wrong with our perception of space and time?
I have to know nothing about the person Mr. Hugh Everett and your totally mad psychological structure in context of your attacks against this person. The idea "multiverse" is a mathematical plausible idea. The problem is it is not provable. So some people call it meta-physics. And physics is not meta-physics. So physicists don't know what to do with this idea now. A similar problem exists in case of the string theory. But for sure both concepts are interesting for physicists.
You didn't read about Everett, did you? I'm entitled to my scientific opinion if I'm peer reviewing his work. His theory didn't pass peer review; did you know that? It was only in more modern times that Schrodinger (who came before Everett (!)) was taken more seriously. Everett is the one who came up with the many worlds interpretation. No one likes to be associated with that mad man. That's why the newer version was called
Multiverse.
Moreover, the creationists have Kalam Cosmological Argument. The multiverse side has no logical argument. They couldn't find anything in the past light in the expanding universe as evidence. Thus, you have nothing anymore. I can explain the wave and it's collapse.
Basically, we have the same facts of the expanding universe. The differences between your view and mine are age of the universe, around 6000 years, vs 13.7 billion years, .

I give up.
