Bohmian Mechanics, also known as Pilot Wave Theory, elegantly describes the interaction of quantum particles. You can imagine a particle bouncing on a sheet with waves emanating around it. Just describing it like that brings to mind a common description of gravity, but that is probably just an amazing coincidence.
One thing Bohmian Mechanics does not explain is what Einstein referred to as "spooky action at a distance," or non-locality.
Non-locality is the notion that two entangled particles can interact with each other at vast distances.
Entanglement can be (overly) simplified with this thought experiment:
Alice and Bob decide to take two pieces of fruit, one apple and one orange. They have an assistant randomize the two pieces of fruit and place them both in identical bags so that Alice and Bob don't know which one is which. Then Alice goes to her home and Bob goes to his.
Once they arrive home, they each look into the bag to see which piece of fruit they have. Alice sees that she has the apple, so she instantly knows that Bob has the orange.
This seems pretty ordinary. Nothing spooky.
But in quantum mechanics, the fruit would be in a superposition. Both bags would literally have both pieces of fruit until inspected. When they look into the bag, the superposition collapses and only one piece of fruit exists in each bag. The collapse happens instantly for both and that's why it's "spooky."
Bohmian Mechanics does not (currently) describe entanglement and non-locality. But it does describe things like quantum tunneling and much of the double slit experiment (except not quantum erasure).
So the neat thing is, Bohmian Mechanics explains a lot of quantum weirdness. But not all. Here are three videos that go into Bohmian Mechanics:

Was watching a video on this last night and how it correlates to simulation theory

I don't know if I should be relieved to know about Bohmian Mechanics or annoyed.
The same kind of "annoyed" as when I found out about dark energy, as in how can the universe be speeding up, what happened to the conservation of momentum?
Pilot Wave Theory could possibly "annoy" me the same way. But I haven't decided if this is the salvation to my own sanity or exactly the opposite. With Pilot Wave, I don't have to worry about "it" being there and not being there at the same time. (It being all the subatomic particles in the universe.) "It" wouldn't be a particle and at the same time. "It" would behave properly. True, we won't know where "it" is and what "its" velocity is at the same time, but that's okay, that would be because we are not smart enough and can't observe "it" that closely, not because "it" is non-deterministic and rides that probability wave nonsense.
But on the other hand, Pilot Wave has a lot of bad implications as well; such as, the universe is caste in stone and nothing we can do can change it. In that case, might as well crawl back to bed and wallow out our depressed lives in squalor until we drop dead or the universe ends in proton-decay, whichever comes first.
Just my two cents,

Actually, it's position and momentum that we cannot know at the same time. What's interesting, if you were to force the situation, using the Pauli exclusion principle, the information will still be hidden.
If you squeeze neutrons enough, so that they begin to violate Pauli exclusion (try to get two neutrons to occupy the same space at the same time), they get so close to one another that you can infer the position of one and the momentum of the other, thereby violate Heisenberg uncertainty, guess what happens?
Instead of violating Pauli or Heisenberg, an event horizon forms, which hides the result. Perhaps you could get the information if you yourself enter the event horizon. But you wouldn't be able to tell anyone.

Thanks, but I don't "do" that small, and I kinda like to get back out of whatever I squeeze into so I can tell the world about it.
Whatever lives way down there, it's NOT a particle, and it's NOT a wave. It only behaves like a particle when we some times look then behaves like a wave at other times.

What I'm describing is a neutron star, so it's large enough to investigate. This is because gravity is the only force that comes close to violating the Pauli exclusion principle for neutrons.

So, from a Game of Thrones perspective, Bohmian Mechanics is going to describe when and where the waves of White Walkers are going to reach the wall. Using Bohmian Mechanics, they will not need Bran's third eye, as they no longer need him to predict what the superposition is of the Night King.
This can be proven with two Hodor's.

Incredible! Thank you for the post. I am excited to further understand these mysteries and be able to understand where previous logic failed. Thank you for educating me even further on quantum mechanics.

To make it simple, quantum particle are energy that makes the whole universe, it's a photon, electron and other particle from exploding atom.
Base on its theory, what happen here is also happening to the other side. With theory, time become possible, however large amount of energy is needed to split an atom.

Referring to the oil drop video, could a droplet stay in the same spot and if so would the altitude of it's bounce increase? I assume that when the droplet hits on a slope of the pool of oil this causes the droplet to move sideways. If the droplet hits the pool at the node there would be no sideways force and it would bounce straight up. If it hits just as the node was rising then some of the energy would be transferred from the pool to the droplet causing the droplet to bounce higher. Does this make any sense? Good video, enjoyed it.

It's possible that what you're describing is an aspect of quantum tunneling. Not sure, though.

I'll have to look up quantum tunneling, I'm not exactly sure what that is. I was just commenting based on the physics of the droplet bouncing on the pool. It appears that as the droplet rises above the pool and the pool is rippling. As the droplet falls it can hit the ripple of the pool on it's up slope, down slope or when it is flat. If it hits on the slope it will cause the droplet to bounce sideways. If it hits on the flat the droplet should rise perpendicular to the pool. Maybe that is explained by quantum tunneling, I do some reading on it. I find it interesting. Also I watched the third video and I don't exactly understand how the interference pattern is created. Especially if the particle can only go through one of the slits, how can it interfere with itself. Thank you for the response.

I missed that the third video was explaining quantum tunneling (I think). I am still trying to figure out how the interference pattern is created. After I watched it again, she said that if they put sensors on the openings to indicate which opening the particle went through then the target pattern changes to the pattern made when there was only one opening. I'll keep trying to make sense of it. Have a nice day.
