Quantum mechanics can be thought of
as an answer to many questions in this universe
and the same quantum mechanics question many of the scientific laws
that have been believed to be true so far
and not just the scientific laws bu
t the practical world we see as untrue
That means there is no science required to say
that an object is here just put eyes
But an experiment in quantum mechanics says
that the object is not there just because you see it,that it is there,
That is, the same double slit experiment raises
the big question of whether our consciousness creates this universe.
We talked about how this experiment gave birth to quantum mechanics
in my previous video
But how do we know through this experiment that the
world we are looking at is not physically there but all that our mind creates?
we need to talk deeply about it to know it.
In this experiment we mainly think that atoms are small particles
so when sending atoms through this double slit plate placed here
they should show a similar double pattern on the screen
behind because atoms should show only two patterns on the back screen
as they travel through those two paths
but so Observed the interference pattern on the back screen
but if we put the same double slit plate in the water
we will see the same interference pattern,
and we can observe same interference pattern with atoms
This means that the atoms behave like waves rather than particles
but atoms are supposed to look like an interference pattern
as they all go together like a wave
but this time we wanted to see how
the atoms go when sent as a single
and the interference pattern also appeared
when some millions of atoms were sent as a single
This means that millions of atoms are sent in a short time gap
but they behave like waves,
This means that the atom must separate and travel together again
or else the atoms will already know where to go and land.
In fact, both are unlikely to happen.
However, when a detector is placed to see
how the actual Atoms are changing like waves
they are shockingly transformed into particles
and appear in a double pattern,
and when we turn off the detector they again show the
interference pattern as waves
However, this event is arguably the most mysterious event
in quantum mechanics
Because an atom looks like a particle when we see it
and behaves like a wave when we don't see it.
But the interesting thing here is
that they change from wave to particle as we observe,
rather than the atom behaving like a wave.
However, many scientists have tried to explain
why this happens in one way or another,
but the most widely accepted interpretation is
the Copenhagen interpretation.
It was proposed in 1925 by Niels Bohr
and Werner Heisenberg
Copenhagen interpretation says that
the ball that appears here is constantly moving
which means it changes its position as it appears everywhere in the traveling path
so that whenever we try to catch it it only gets caught in our hand in one place
but the same happens in copenhagen interpretation
The atom can be in several different places at the same time
so according to the wave recorded on the back screen,
once the atom is in this place
it will be in this place again
This means that the wave is always moving
so it cannot be said that the wave is a near constant
as well as when it behaves like an atomic wave
it will go there and land depending on where it is.
Simply put, a particle can be in
two different places at the same time
so when we observe it,
it is forced to stay in the same place,
so it becomes a reality,
and when we detect it with a detector, its wave function collapses
The main purpose of the Copenhagen interpretation is to look like
just a particle so it goes like a particle and shows a double pattern.
This is what we think of as probability
If we do not observe it, it will behave like a wave,
so we can never see the wave,
but when we see it,
the wave will change into a particle.
That is, this universe made up of the same
particle is only visible when we see it,
and if we do not see it,
the universe will turn into a wave again and disappear.
Without the observer, the universe would not exist
this is sensational interpretation in scientific community
This is because a particle cannot be said to be exactly in one place in a vacuum.
In other words, the original particle is not physical
From this we can understand how unique the quantum world is
but at one point Albert Einstein tried to prove it wrong
because the rules in the quantum world also apply to the physical world
so he also gave a statement that the moon is there even when it is not seen
Unable to prove interpretation wrong
Leaving this aside,
another famous interpretation of why the wave function collapses is
von Neumann–Wigner interpretation
it says that the wave must appear as a particle,
which means that human consciousness is necessary
Because we can never see that a water wave is constant.
Because the wave nature is not constant.
Whenever we think of a particle
our consciousness actually forces the wave to turn into a particle
so it only appears as a particle.
example When a car is going at speed we cannot see it clearly
so we have to look at it clearly while it is traveling
which means that the car is reflected in our mind as clear when we look at it
sharply assuming that it is constant,
Exactly the same wave function also occurs in collapse
In a way it is a paradox
And depending on this,
we can think that our consciousness creates every object in this world
which means that the world we see every day is just a magical world
and we are creating it ourselves.
We wonder if we can believe all this is true.
But the scientific community is still unable to answer why the wave function collapses,
which means that there is still no theory to prove,
including evidence,
that in a sense, according to quantum mechanics
this universe is just like our dream,
that our brain creates a new world in a dream
and that the same is true.
It is believed to be strong
In fact, they are not only true
, they are created in the dream world
That is, our mind has created reality,
Quantum mechanics is exactly the same,
but here we can think of what consciousness is,
even though consciousness means awareness
the word consciousness also represents the sense of self
as well as the sense of experiencing the outside world,
However, we have not yet figured out how this consciousness is created in our brain.
In a way it means that our brain can feel any consciousness
but there is no medical evidence for it,
and the previously mentioned Copenhagen interpretation also
raises some philosophical questions
That is, we assume that the universe exists only when we look at it
thus creating a doubt as to whether the world will dissolve with a man when he dies.
If the same is true
then the reality of every human being in this world becomes a big question mark
Another question is
whether human consciousness is the only cause of wave function collapse
or the consciousness of any animal.
However,
quantum mechanics can be thought of as supporting philosophical interpretation
while questioning objective reality
Otherwise science accepts only the physical aspects
but the results in quantum mechanics are in the philosophical context
However, I mean that if the physical aspects of science are used to develop technically,
the results in quantum mechanics will be used to
reach a higher level in terms of consciousness,
then they will be able to use quantum mechanics properly.
Science and philosophy are respected only as long as they are useful to man in an ethical way
But in the next video we will talk about
how many more explanations there are for wave function collapse
