Many thanks and shout-out to David Tong's lecture on Quantum Fields for inspiring this video. I highly recommend his free lecture series. In my opinion, he and Richard Feynman are two of the best educators in physics.
What is the universe really made of? What is truly fundamental in the reality that we perceive? This video is about QFT: Quantum field theory - simplified.
Everything that you see is thought to be made of up of particles. This is what most people are taught in science class. The only problem is it is not true. And physicists have known this for decades. Particles are really not fundamental. The best theory in physics tells us that there really are no particles at all, only fields. Particles are merely waves in the field.
Fields are fluid-like substances that can be perturbed, vibrate, and experience excitations. What exactly are fields? Mathematically a field something that takes a value at every point in space. They are not really made of anything other than that from a strictly physicist’s point of view. If you have a fireplace in a room, the temperature at every point in that room would have a value. This would be a field of temperature - this is analogous to the quantum fields.
The vacuum of space is alive with these fields. The Heisenberg uncertainty principle means that a quantum field cannot sit still. Instead, They are vibrating and changing their value over time. All you can see is really only the excitations of 4 of the fields - Electromagnetic, electron, up quark, and down quark fields. But there are more. The total number of fields is 17, including the Higgs field. Space-time itself is thought to be a field, but so far has not been able to be incorporated in quantum field theory. It would be the 18th field.
One way to visualize the fields is to Imagine the volume of the universe being filled with about 17 different kinds of differently colored fluids instead of water.
Fields eliminate is the idea of action at a distance. In Newtonian gravity, the sun affects the earth which is 120 million kilometers away without touching it. Even Newton thought this was absurd. Einstein’s theory of general relativity eliminated this idea of action at a distance by replacing space with space-time, which is a field that pervades all of reality. In order for a force to propagate over distances, it has to affect its field locally, then propagate from the local point to the distant point, then affect the field locally at the distant point.
Fields can also explain how particles can be created and destroyed. When a Neutron decays to a Proton, an electron, and an antineutrino, it does this by giving its vibrations or energy away to the quarks fields of the Proton, electron field and antineutrino fields.
When you call someone on your cell phone, you are putting excitations in a field and affecting the electronics within the cell phone of the person you are calling. This is field excitations in practice.
#QFT
#quantumfieldtheory
But quantum mechanics is about discreet things yet fields are continuous. The combining of field theory with quantum mechanics is called quantum field theory or QFT. This means the excitations of fields happen only in chunks of energy. The energy of the wave is determined by the mass of the particle. The mass is just the energy needed to vibrate its field. The field will simply not accept energies below a certain threshold.
This discrete unit of energy that the field can accept is what we call the rest mass energy of particles in a field.
Fields are related to the probability waves of quantum mechanics and the Schrodinger equation by their shape. The shape of the electric field is the wavefunction of electrons, for example.
The wave function is what really exists. A "particle" is created when you measure the electron wave. This is when the wave function has collapsed into a discrete value. This can be predicted by the Schordinger equation. A particle has a location, but a field is spread out everywhere.
Who discovered fields? Michael Faraday came up with the idea and actually used the word “field” in his notebook in 1845.
Are fields a real thing, or are they just mathematical constructs? Most physicists believe them to be physical reality.
Are these fields fundamental? - only in the sense that it is the limit of our understanding. Fields may be just an approximation of a deeper level of reality.

[@mrgeek434]

You're not going to get any meaningful understanding of QFT from KZbin videos aimed at a popular audience. If you truly want to get to grips with it, you need to master the prerequisite backgrounds (in terms of the mathematics and physics), and then work through a standard introductory QFT textbook. That takes about 3-5 years of work, though.

[@nickpaine]

@@mrgeek434 I'm not a master of anything but I think a person of rather ordinary intelligence can grasp the basics of this if he has a fundamentally sound science foundation. I'm one. This is beyond my deeper comprehension, but I get the gist. There always seems to be useful analogies. Those are sufficient to general understanding, it seems to me.

[@gold333]

What if you excite the field with one and a half electron masses? Sure you create one electron. And the energy of the other half? In other words, what if you add energy that is less than 1 quanta of any particle? What happens to that energy?

[@keithmccann6601]

Is it just me or does anyone else feel that the deeper you dig into the science of reality the more metaphysical and philosophical it all starts to feel - like i just realised that we are all very joined up by these fields to everyone and everthing else - like we are all just constituent parts of a single entity - the universe - not very scientific i know but it makes you think.........

And yet very scientific! This is why Quantum Entanglement works! Because it is actually connected, all the time.

[@ekszentrik]

Really the only reason we perceive us as separated is because we are humans with an individuality. Nothing defines objects (or beings) as separate except humans extrapolating their subjective experience onto the external world (there are no "stars" as singular objects for example, only stars as arbitrary subcomponents of totality). Our self is the greatest mystery.

What I fail to understand is how is there so much order in the human scale when everything is so tenuous at the quantum scale. We don't see things jump in and go out of existence in real life randomly. There is a definite continuity that doesn't square with the randomness at the quantum level. Maybe we'll have to wait for the Theory of Everything to explain that.

I have an engineering background, and took many courses in physics, math, and chemistry. I can accept that fields are what constitute all matter (and anti-matter) in the universe. I can also accept that when fields aggregate in a particular area, they can produce a solid, be it a ball or a piece of furniture. What I can't understand is why fields collapse when humans (or other living beings?) observe them.

[@ArvinAsh]

Keep in mind that quantum observation does not mean human or animal observation. An observation is a measurement, it can be any interaction with a classical object - no mind is necessary. But, yes, measurement is still a problem, because the mechanism of collapse is not known. I have talked about it in many videos including my latest one. There are other interpretations as well, where wave functions collapse really does not happen. I will talk about one such interpretation in the video coming this week. Take a look, I think you will find it interesting.

Nobel Prize-winning physicist Richard Feynman said that if he couldn't explain an advanced physics theory to his first year students, he had to admit that he really didn't understand it himself. He also famously said, "I think I can safely say that no one understands quantum mechanics." THAT is wisdom. And here's the simple understanding that the wisest of physicists, like Max Planck, have come to (see his 1944 Florence Italy lecture "On the Nature of Matter): What the Universe is REALLY made of is so simple that it can be stated in TWO WORDS. But if you were to accept that simple truth, then what would you do? You couldn't make endless speculative videos or magazines about IT, because there is no longer any need for speculation. Science can't make money off of IT, because IT is free and within grasp of even the simplest of men. You wouldn't build multi-billion dollar particle accelerators, because IT cannot be divided. You can't make a bomb out of IT, so governments would have no motivation to admit the truth. You couldn't make a living off of IT by writing books, because the book that explains everything has already been written. And that book is tiny, and it is free: "The Book of God" at A Course in Truth website. For, "GOD" is simply Reality; "GOD" is the Mind that is ALL.

So, this explain may how all the matter of the universe could have existed in one dimensionless singularity. Similarly, perhaps the proposition of singularities at the center of black holes is the result of the 'unravelling' of particles back to their field components. At any rate, a spectacular presentation. succinct and understandable.

[@z3dar]

It's not too hard to imagine that a field of energy without high or low enough excitations to form quarks/matter could be compressed to a zero-sum singularity. Fields can be compressed, so "empty" fields can be compressed to a point, no? Maybe a good question would be what could've done the compressing of fields and why is the universe now expanding infinitely instead of being compressed from outside. It's almost as if someone pushed play on a universe simulation... :] Relating to above... Can gravity have any effect if the other fields don't have any matter, even quarks? In other words, could gravity have held the singularity universe together before big bang, or did gravity only start to have an effect after first matter formed? This is probably not the best place to ask these, but maybe someone knowledgeable will answer these, or can correct me if they are nonsensical ideas.

Yes it is but yet we need to understand the very beginning of this energy. We will not know coz its hidden from us we can see at only cosmic microwave background but not before that.

Great video. Love science so thought provoking. I try to learn something everyday. It's a challenge but it's very rewarding.

[@ArvinAsh]

Good for you! More people should be more curious like you.

[@houssemtivano5180]

This video is one of the best in your channel Thank you for more information

[@Siran4228]

You explain better and more thoroughly than anyone else I’ve seen

[@Sirillius]

This video definitely helped put certain things into perspective for me, thank you.

[@satishgoda]

My mind just disintegrated amongst this field of exquisite instruction. Thank you :)

[@rockestee]

[@ArvinAsh]

Thanks for watching. Much appreciated.

[@theswissroadtocrypto]

Great explanation,! Arvin Ash explains these concepts incredibly well and the images help you visualize what he is saying

[@timelschner8451]

Excellent content, as always! Many thanks for your great efforts.

[@sethmontana2683]

Great video! I learned so much in this video than some others👍🏼

[@NalitaQubit]

Such a great video…… thanks Arvin for your hard work!

[@iamtechnicallyasandwich566]

This is amazing, it makes so much more sense now.

[@jaikumar848]

It's really great video. ..best part is...easy to understand

[@InfamoussDBZ]

Wow...that was explained wonderfully. The visual aids are phenomenal. It is becoming difficult to understand what is real and what is not; when we can measure something's effects without a full understanding of what it is we're measuring. Mentioning these fields are real, helped.

[@TheRenegade2424]

Ty for teaching 🤙🏽 and he’s right Magellan is awesome

[@drewishaf]

I thought my mind was blown until I heard Mr. Ash quote Donald Rumsfeld. Double blown

[@hebruixe9125]

Fascinating video. Arvin you're awesome.

[@coevad3961]

This one of Arvin’s best videos that I have seen of his.

[@jeancorriveau8686]

Another excellent video from Alvin Ash! So easy to understand. Quantum physics make a lot of sense now.

[@Harshil2456]

Arvin is a great teacher, way better than some lecturers I've had in college!

[@arhamqadeer6520]

This was some mind boggling stuff.I never thought that we could think of particles as field,bringing us closer to the fundamental nature of reality.
