This episode of #kahwati is about "nothing"
Hi again, I'm Zainab Al Shammari
If the previous episode about Quantum mechanics made you dizzy, then you’re on the right track!
As what Neihl Bohr’s said
"And anyone who thinks they can talk about quantum theory without feeling dizzy hasn't yet understood the first thing about it."
Today I’ll talk about Heisenberg’s Uncertainty Principle
which is one of the most important principles in quantum mechanics.
Let’s get started!
If I asked you about this jar, is it empty or not?
You might say it’s empty. Is it?
The jar isn’t empty because it has air molecules of oxygen, co2, photons of light, heat, radiations, etc.
If I emptied it from every molecule and cooled it down to about zero Kelvin
and shielded it from any radiation.
It would be an empty vacuum.
Still it doesn’t mean it has “nothing”.
The reason is: Heisenberg’s Uncertainty Principle
This principle was developed by the German scientist Heisenberg.
This principle says that the position and the velocity of an object
cannot both be measured exactly at the same time according to this equation
Delta p is the uncertainty of momentum
Delta x is the uncertainty in position
If we say that the vacuum has nothing in it
this means that we have determined the position of the particle and its speed, which is zero
This violates the equation
This is because the result of this side of the equation should be more than zero
Just as you can see here, this sign.
If you determine the position of the particle, the velocity of the particle becomes blurred or undetermined or uncertain.
The reason why the velocity is not determined is not because there is no device that can measure it.
It is just impossible within the limits of our universe.
This concept has been applied in order to try to understand our universe.
How did it start?
Did it actually start from "nothing"?
Did quantum fluctuations really appear from nothing and that it annihilates each other.
Just like how positive and negative energy appear and then annihilate each other?!
Or matter and antimatter appearing and then annihilating each other.
These virtual particles appear and then disappear because empty space has no emptiness.
Einstein opposed the Uncertainty Principle at that time and said his famous saying
"God does not play dice."
However, this physical principle is experimentally proven and it turns out that Einstein was wrong.
So, we conclude from the Uncertainty Principle that the vacuum of space can’t be completely empty from any quantum fluctuations
because if it was empty, we would have determined the position and velocity of the particle and fixed it to zero and this is a violation of the equation.
So as a result, the cosmic vacuum in which we live in is full of quantum fluctuations.
Hence, this proves that the cosmic vacuum produces particles from nothing.
This is from a physical standpoint, not a philosophical one.
Some physicists such as Stephen Hawking and Stephen Weinberg
used this principle to prove that there is no need for a God
because the universe started by a Quantum event.
So if the quanta are produced from nothing, then the universe came from nothing.
Without the intervention of a God.
This is not an easy case.
So when someone comes here and comments, why do you associate science with religion?
I would answer him because this is what is happening.
Some scientists claim that science is enough to explain our universe, hence there is no need for the existence of God.
They say that science has answered all the great questions and explained the causes that were unknown.
Therefore, there are no more gaps left allowing you to smuggle in your God as a cause for something to occur or start.
I haven’t read a convincing answer to this issue so far other than the book Atheism Delusion by Ahmed Al Hasan.
Even if it is empirically proven that our cosmic vacuum produces something from nothing
We cannot ,within the limits of our universe, determine a real reason for the fact that the vacuum of space produced something from nothing
Or that quantum fluctuations appear and disappear within the vacuum.
I have mentioned this before in the previous episode which I will link below
so make sure to check it out after this video.
I mentioned in the previous episode that nullifying causality
is an escape from the solution and not a solution.
I also offered one of the scientific solutions presented by the scientist Hugh Everett III.
Hugh assumed the existence of multiple universes/many worlds
and that the possibilities which don't occur in our universe, occur in other universes.
Ahmed Alhasan said in the book Atheism Delusion:
“Therefore, some astronomers and theoretical physicists such as Stephen Hawking, Lawrence Krauss,
and other enthusiasts of the phrase “something out of nothing”-
”- the phrase upon which they said that the universe appeared from nothing, needless of a God-
those enthusiasts have built their structure upon a philosophical, undetermined issue in quantum mechanics
for which there is no evidence whatsoever: nullifying causality
This is despite the knowledge that the Many Universes theory is a strong competitor,
and that explained gravity, for instance, can be a trace coming from another universe.
The same is the case with regard to the quantum fluctuations in the universe in which we live:
it does not negate these fluctuations being traces that reach us from other universes”.
-Atheism Delusion pg.468 (English version)
Thus, what Stephen Hawking, Lawrence Krauss and others have built concerning atheism
becomes a collapsing, scientifically contradictory structure.
This is because nullifying causality contradicts the theory of many universes.
There is a lot more to talk about regarding Quantum Mechanics and Scientific Atheism.
so science itself is fine and I hope you keep on learning.
