I agree, and it was explained in a simple fashion. It's a hard concept to grasp that electrons
can be both matter and wave light at the same time. Most people would conclude that science is a
black and white topic, things either are or they are not, but this shows that there are grey
areas in what we think we know.

That's not really the conclusion you eventually come to learning more about QM... More, what you
find out is that reality actually plays by entirely different rules than it appears to.
What QM seems to say, at least in my understanding of it, I could be entirely wrong here, is that
reality as we know it is defined by interactions between particles IE entanglements. When
something has no entanglements with any other particle, it may as well be nonexistent. And these
entanglements are the same thing as cause and effect, or observation (observing something causes
it to have an effect on your measuring apparatus, so it's the same thing).

So, in order for you to know that, for example, Napoleon tried and failed to invade Russia
because of the cold, there needs to be an entanglement directly from the event to your
comprehending mind. Now, not having that information doesn't preclude the quadrillion-quadrillion
waveforms that make up such an event from collapsing and making it to where that event DID happen
in your universe, but by definition if the waveform hasn't collapsed, you can't know anything
about its result.
This could explain why time ONLY moves forwards, because quantum waveforms can only collapse, not
de-collapse (unless another source of entropy is applied) or it may explain why it's impossible
to go faster than light.

Basically, things ARE playing by rules, extremely weird unexpected rules, but rules nonetheless.
That's the only reason we're even able to formulate a theory behind their behavior.

Matter decides to act as a particle or a wave based upon the fashion it is observed. The strange
thing about quantum mechanics is that, if it is not observed, there is no definite state. Until
observed, the outcome is literally completely unknowable, exemplified in its extreme by
Schrôdinger's cat.

What if our world is just a computer simulation.
That would explain, why the particles behave differently when being watched. It's like if you
were a programmer for such a simulation and you have limited resources, you have to make a cut at
a certain point of depth. And that depth would be the quantum level. so as a programmer you just
return a random number if this function is called. This would also solve the Uncertainty
principle because it is only a cause of the abstraction of the programmer. In the world, where
the simulation runs, the Uncertainty principle may not apply making it possible to store infinite
amounts of information at a given space thus making a big simulation like the world we live in
possible.

But there are quadrillions of entanglements between every single particle. One could say that
reality emerges from these entanglements, and more are forming all the time. All of your history,
your memory, is based on entanglements to the particles that made up situations that came before.
An intert cube of pure metal will have an incomprehensible number of entanglements; to the
pickaxes of the miners who dug it up, the memories of said miners (via light reflecting off the
surface of the ore) the smelting ovens that purified it, the milling apparati that carved and
shaped it. All the things that led to it being as it is now are so because of their previous
interactions with other particles, in addition to being entangled with every other particle in
its structure.
This is probably why quantum stuff never happens on a macroscopic level; there's always some
interaction that collapses the waveform, even if not comprehended.

Anyway, my point is that if I was designing a matrix, I would not use this model to simulate our
reality as it is now, unless our current reality wasn't necessarily the goal (or at least the
only possible goal) of the simulation.

No really, if you have only studied Newtonian physics, don't expect quantum to make sense, they
won't, it doesn't even make sense when you have studied them anyway, about 1º or 2º month you
wonder how the fuck does all make sense, but proof points it actually makes sense, so you nod

Because you can't observe something without interacting with it. To observe anything, light must
bounce off of it and back to your eyeball. This "Bouncing off," or causing an effect, is what
they used to think collapsed the wave form.
But, through further experiments, we can prove that it isn't just a deficiency of our tools that
causes this, but the very nature of observing something necessitates that it take on either one
state or the other.
Contd...

Brace yourself, because this is the absolutely transcendently weird part. If we use our tools to
observe something then DELETE THAT DATA LATER WITHOUT LOOKING AT IT OR LETTING IT INTERACT WITH
ANYTHING IN ANY WAY, the waveform DE-COLLAPSES, and you get a motherfucking interference pattern!
THAT'S SO FUCKED UP! The waveform collapsed because it had an effect on something somwhere else
in the universe. It took on its state, for one way or another, only based upon its entanglement
with some other particle somewhere else. If the results of that interaction are destroyed, it has
no reason to be one-way-or-the-other, so it goes back to being "wavelike". Our entire reality
only exists because of the interactions of all these particles!

I didn't want to nod my head and move on, so I looked at wikipedia and read this:
"[T]he observer can decide whether or not to put detectors into the interfering path. That way,
by deciding whether or not to determine the path through the two-slit experiment, he/she can
decide which property can become reality. If he/she chooses not to put the detectors there, then
the interference pattern will become reality; if he/she does put the detectors there, then the
beam path will become reality. Yet, most importantly, the observer has no influence on the
specific element of the world that becomes reality. Specifically, if he/she chooses to determine
the path, then he/she has no influence whatsoever over which of the two paths, the left one or
the right one, nature will tell him/her is the one in which the particle is found..."

"...Likewise, if he/she chooses to observe the interference pattern, then he/she has no influence

If you have to "just nod your head and move on" you don't really understand it. If you keep

Most of quantum mechanics isn't mystical, just poorly explained. All the uncertainty principles

My only issue with this flash is that it represents observation as an eye, when in the real world
observation means interfering with the experiment with some device, hence the different behavior.

The reason it changes states is because its real when observed, and only an abstract on the back
board when its not.
(meaning the resulting abstract waveform is only caused because you cant see what your not
looking at, and when your not looking at it its not real, but your looking at a result so that's
real though more variable/abstract.)
Full circle;
Tree falls in a forest, no ones around to hear or see it, does it make a sound?
No, because It doesn't exist until observed, there only being a chance it fell until seen again.
