    Today I’m going to explain why you’re not falling through your chair right now using one simple fact, and one object. The fact is that all electrons are the same as each other, and the object is a structurally critical item of my clothing. There’s a chance this episode could get very weird.

... I've been thinking about this since we talked about the concept of the speed of light- Couldn't the quantum fields we know of, and virtual particles be considered Aether? As in the Luminiferous Aether that classical physicists came up with way back when? Granted they obv didn't have the math down, and were missing some things, but fundamentally weren't they right to presume that light doesn't travel through a non medium since even the vacuum of spacetime randomly has particles pop into existence according to the uncertainty principle?

You’re really fun. “To summarize again…” The probability of measuring a wavefunction is called psi. If we’re trying to identify the position of electrons (A,B) we’d define it as psi(A,B). Since there is a ground state and an excited state, and since each electron can bounce between we define the collective superposition as psi(A,B) = f(A)g(B) - f(B)g(A) The reason we’re able to identify them as positive and negative is because with fermions, a single rotational spin is analogous to a change in position which would account to a half phase shift in the wavefunction, denoted by the negative symbol. This is true for all spinners. I don’t understand why, mathematically, we can’t have two in the ground state. I’ll keep thinking, but you wrote out that their values would cancel leaving 0. Which means they’d inhabit the same same, they don’t. But you didn’t explain why? There doesn’t seem to be a reason why they can’t be in the ground state, I’m assuming there isn’t any space available to change a position variable and they’d have to inhabit the same space. Which is why their functions cancel so easily in your example. I still don’t understand why? Like it makes sense that we would use antisymmetic wavefunctions as a template to map and prove but you don’t explain why? Lol The business about the spinning seemed to be a physical phenomenon of objects spinning in space. Hence your ability to use your hands as examples and coincidentally, we’re all made of matter. You’re also saying the spin of an electron allows us to map out the probability amplitude if singular electrons too? Because they’re spin half means their wavefunctions are defined anti-symmetrically. Why do we define the wavefunctions along one full spin? If I understand correctly the antisymmetic portion of the equation refers to a rotation or when they switch places. Why do we choose only those two points in time? Is it because it’s the easiest to mathematically define? psi(A,B) refers to the aggregate and f(A)g(B) - f(B)g(A) refers to the two states we observe to map the rest of the behavior? Or rather, the wavefunction is defined by psi in the aggregate and by the component parts because of their ease to mathematically define those two points in space time. After one rotation or swap, then returning to normal. For example we could break it down into 16 parts, so long as they were symmetrical intervals of time, then we’d have an outrageous equation. Okay, proof by contradiction because when we use symmetrical wavefunctions they become unbound. Or rather, matter wouldn’t behave in the way we observe. I’ll trust you with the math and ruminate on what that means. Because they’re antisymmetic only one wavefunction can be in a place at a time, mathematically.

Imagine servers that can perform quantum spin calculations. It is possible with quantum servers where one grid calculates instructions, the other one stays dormant, and vice versa. The key is in the formation of the grid of one server to the next whether they are side by side or stacked.

could it be that our convention of matter is wrong? The difference between matter and antimatter is in charge, however we have assigned both charges to our definition of matter. Why not consider positive charge to be matter, so the up quark is matter, and the negative charges to be antimatter, so the down quark and electron are antimatter (or the other way around). This would mean that we would have equal quantities of both, and symmetry will only break locally depending on which you have most, and it also means we are made of both matter and antimatter, and there would be no need for dark energy. The reason the electron orbits the proton, is that the proton has both positive and negative charges in its quarks, so the electron is attracted to the up quarks, but repelled by the down quark, and get locked in a orbit. In case of high energies, the proton can absorb the electron, and thus turning intro a neutron, which would have 2 negatively charged quark and one positive one. However since locally we have more matter, only protons can be free, neutrons can only be inside atoms (or free in extreme conditions).

The proof by contradiction you gave makes sense, but isn't there an easier one? I mean, if A and B inhabit the same space. Then, you can swap A and B without fundamentally doing anything. This would cause the wavefunction to flip in sign. But yet, you haven't done anything, so the wave function must be what it was before. Therefore, the wavefunction must just be 0. So clearly, there's a contradiction, and A and B cannot inhabit the same space, without the wavefunction simply declaring that A and B do not exist.

Every explanation of the Pauli Exclusion Principle (including this one) that I've seen goes something like "Well, the mathematical objects that we use to represent electrons lead to this conclusion, so two electrons can't occupy the same state", but that doesn't really tell us what is happening physically. To put what I'm saying a little more concretely, say I have a lithium ion with two electrons in the ground state. A third electron comes along. What PHYSICAL INTERACTION (that the math is representing) keeps that third electron out of the ground state?

In entanglement we measure a particle with a 720 degree twist with the other particle for that we see different state at the other entangled particle. Could instant double measurement give us that same state of entangled particles? I think the answer is no because each measument is giving us the movement of each degree of the720 degree movement.

If we can't observe Psi, how do we know this is actually what is going on? Is it that this exclusion principle MUST be true or the model doesn't work? I suspect there is something more to quantum field theory going on that allows Bosons to occupy the same space and Fermions not. To keep it aligned with "quantum wave" theory, I suggest that Fermions are limited by a pilot wave frequency in normal space, and Bosons have a pilot wave in a dimension we do not interact with, but that allows them to occupy they same position in what we observe as our 4 dimensional space.

I'm a little disappointed by PBS Space Time playing fast and loose with the terminology recently. A good example of this comes from 7:40. A 360-degree rotation isn't equivalent to "add[ing] -1 to [the] wavefunction" (in other words, subtracting 1); it's equivalent to _negating_ the wavefunction. I understand that this isn't an actual physics course, but that was still a needlessly inaccurate phrasing.

The universe is a very simple place. By using the laws of parsimony or Occam’s razor, we can reduce the complexity of the universe. According to the law of parsimony, which is the problem-solving principle that the simplest solution tends to be the correct one when presented with competing hypotheses to solve a problem; one should select the solution with the fewest assumptions. Using this basic principle, we can start with the fewest number of particles that the universe can be made of. The answer to this must be, only one particle, because that is the smallest possible number that is available and it is a good starting point. Now, we need to give this particle a shape. What is the simplest possible shape that the universe has to offer? The answer being; - the sphere. Yes, the sphere is the simplest possible shape. Well, now that we have established a number and a shape of this particle, we will need to add some states or functions for this particle so that it can create a diverse universe of matter, space, gravity, energy and light. Well, that seems to be a pretty tall order for just one simple particle to perform, so how does this particle do such complex functions? Firstly, I’ll ask Nikola Tesla to see if he has any clues. “Nikola, how does the universe work?” Nikola says “the number 3 holds the secrets to how the universe works”. Thanks Nicola! I’ll take your advice and have a close look at nature to see how many times that the number 3 appears. Well, Nikola, it looks like you were right! The number 3 appears to be popping up everywhere when I look at fundamental elements and nature in general. Let’s make a list of what we can find – 1. The atom has an electron, proton and neutron – well that’s 3! That’s a good start! 2. The electric plug has 3 points - positive, negative and earth. Getting better! 3. In chemistry, there is acid, alkaline and neutral (3) Wonderful! 4. There are 3 states of matter – gas, liquid and solid. (Note – plasma is just a gas which is being pushed by aether flow) Phew!! That was a close one! 5. The human eye has 3 colour selection cones; red, blue and green. Perfect! 6. The brain sees the world in sections of 3 which is called the rule of thirds. It’s too good to be true, surely! 7. All sub-atomic particles come in groups of 3. Marvellous! That’s just the icing on the cake! 8. 3 dimensions of space - height, breadth and width. 9. 3 Fractal dimensions - atoms, solar systems and galaxies. 10. The Equation E=MC^ has 3 parts. Thus, we can plainly see that the universe uses the number three at a fundamental level for all basic things. Thus, we can interpret this as a consequence that the ultimate particle must have 3 states or functions. Now, we have established that a sphere has 3 states or functions. So what 3 actions can a sphere in frictionless space perform? Well, I can only think of 3 possible movements that a sphere in frictionless space can do which are left spin, right spin or no spin. Thus, we now have a complete picture of the least number of particles; the simplest shape and simplest functions. Thus, according to the laws of parsimony, the universe would make a fundamental particle in this manner, if it was a logical universe which didn’t have any wastage or superfluous activity.

HOW AND WHY E=MC2 IS NECESSARILY AND CLEARLY F=MA ON BALANCE, AS ELECTROMAGNETISM/energy is gravity: Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. C4 is the proof of the fact that E=mc2 IS F=ma ON BALANCE. This explains the fourth dimension. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=MA ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma. ("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity.) The EARTH/ground AND what is THE SUN are CLEARLY (on balance) E=MC2 AS F=ma. TIME dilation ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma IN BALANCE, AS ELECTROMAGNETISM/energy is gravity !!! (Gravity IS ELECTROMAGNETISM/energy.) The sky is blue, AND THE EARTH is ALSO BLUE. The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma ON BALANCE. Great !!! This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! It all CLEARLY makes perfect sense. BALANCE AND completeness go hand in hand. E=MC2 IS F=ma. The MIDDLE DISTANCE is thus balanced with/as the full distance (in/of space), as the stars AND PLANETS are POINTS in the night sky. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Time DILATION ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. Indeed, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. (The sky is BLUE, AND THE EARTH IS ALSO BLUE; AND the stars AND PLANETS are POINTS in the night sky.) It all CLEARLY does make perfect sense.

Hang on a minute … Matt, you state that, 1)PSI can not be observed. Fine. But then you state that only a distribution designated as PSI SQUARED can be derived by mapping multiple measurements. If #1 is true then what exactly is being measured (a measurement must be an observation of some sort) multiple times to give us #2? In your presentation you did not actually say, but basic logic and the simple way that language works indicate that the measurements were of PSI or some correlated property of PSI. But #1 and #2 can’t both be true - right?

Believing in and seeing evidence of intelligent life beyond this apparent world is something most people genuinely hope for deep down. The full implications of even a single sighting being genuinely real is almost to good to be true, it confirms everything I've wished for my whole life, and many others. The reality we are in here and now isn't real in the way we think it is. It's real because we believe it's real and all there is, but there is a shocking bigger picture. Peoples heads might literally explode if they suddenly could comprehend what this bigger picture is, it is that shocking. I could never -fully- believe in an optimistic worldview like this with all the apparent suffering in nature - animal suffering, how could a loving "god" setup a world with that going on. I'm just going to blatantly say it: I've figured it out. This reality is the most elaborate prank of all time, setup to make us believe we are something we are not. "mother nature" is no different whatsoever than any human made technology, it is "manmade" technology in fact. No "God" exists that created the plants, animals, cell, human bodies even. Nope it's just mere technology INTENTIONALLY SETUP TO MAKE IT LOOK LIKE BENEVOLENT OUTSIDE INTELLIGENCE DOESN'T EXIST. That is all. everything we learn in science about evolution and our history of having evolved from animals, or religious fairy tales like the garden of Eden, are just cover stories to hide what is actually going on. There is no such thing as death, conscious death, we aren't bodies but have been forced into believing we are, we are in fact something FAR FAR more than mere bodies. Genuine consciousness is the only real value thing in all existence. It has been unfairly farmed through our suffering for the benefit of the power brokers ruling this world. It is allowed to happen like this, because it also serves as the ULTIMATE test of true character and true love. But it is just a game, a cosmic hoax, prank, with loving implications that reach beyond understanding. It's a riddle, a test. That is it.

Are you talking about the inverse Breit-Wheeler process? That isn't really a new concept, just new experimental evidence. All quantum processes are reversible, so if it is possible for two particles to annihilate into two photons, then two photons must also be able to create those two particles. This has now been shown in experiment. Unfortunately that isn't new physics, just more confirmation of the standard model.

If you could watch a star collapse into a black hole it would look like an eye closing where the last bit of light you'd see would be what comes out at 90 degrees from the equator of the star. If you could fall into a black hole and not die eventually a dim neutron star would appear and it would get brighter as you got closer. FYI inside every black hole is an extreamly dense neutron star. It's just so dense it doesn't let light escape but if you could spin it up so it would expand it would reappear. I guarantee I'm right. I started working out the math to shut some people up plus it'll help get closer to a theory of everything.

I've recently been researching Quantum Physics. I'm nobody special, just a retired 63 year old chef with an inquisitive mind and too much time on my hands. I have a question... Consider the concept of "magic" in relation to Quantum Physics. What if SOME of the people labeled sorcerer's, witches, etc, were somehow able to influence the quantum world before it is observed? Could they, without knowing how they do it, cause results that could be interpreted as magic or witchcraft? See? Entirely too much time on my hands.

Why do quarks have a fractional charge?

Convention. We could just say the quarks have charges 2 and 1 and all the other particles have charges 3 or 0. We just discovered the electron first and said it has charge 1 and stuck with that. _Why_ the other particles must have those charges is part of the "color confinement" in quantum chromo dynamics and I don't think it is actually fully understood.

If an electron is a point-like particle, where does the photon emited by it comes from?

Amy chance of talking about Cooper Pairs in superconductors? Two electrons form a pair with the same energy level -> sounds like it violates Pauli’s Exclusion Theory. I was told the electron pairs form a composite boson so get around exclusion. I have absolutely no idea how or why that works, though…

And is it the Pauli exclusion principle that, in addition for allowing there to be sound, also allows us to distinguish sounds from each other by disallowing the waves to become confused? I think I saw this on another video on another channel.

自旋是量子自秉屬性, 所謂自秉屬性就是只知其然,而不自其所以然! 量子的自旋有0,1/2,1,3/2 , ...... 由於量子的自旋有很多樣態,所以量子計算機的能力比已知的超級計算機能力高出非常多, 當量子計算機成為商品化時,整個世界將完全改觀! 60年前電晶體的理論提出時,其理論系統尚未完整,但是電晶體已經在非常多的領域被使用! 60年後3nm 的晶片已經作風險性的量產,2nm 的晶片已經試產! 所以量子力學的理論尚未被人類完全理解之前,量子力學的應用早已經上線,如果量子計算機商品化,世界豈不是要天翻地覆! 那時候人類的智慧將是« 無價 »!

Wait, but what about other fermions? Are they too indistinguishable from each other? Because they too seem to not occupy the same space. But for some reason it is only electrons that are talked about in this context. Maybe the other fermions use some other principle to not collapse into one another?

I guess a theory concluding that we fall through our chair would be quite useless. So in that sense, we don't fall through our chair because we don't fall through our chair. However, it is extraordinary that we have found a theory which, when considering interactions between chairs and humans, gives satisfying predictions on vastly different size scales

I’m learning quantum computing (i.e. software & not hardware) & I learnt that qubits achieve superposition via entanglement across 2 electrons in 2 different atoms (an electron in ground state is |0> & in first excited state |1>). After watching this episode, im wondering why aren’t quantum computer hardware implementations using electrons in the same atom to achieve the superposition?!

Electron spin makes matter possible. Leftist ideology makes reality optional. "Let me be clear : I'm just thinking ahead. Venezuela went full Leftist, and in a few years they couldn't buy essentials, like toilet paper. The Venezuelan currency was literally worth less than toilet paper. To make our Socialist Utopia, I'll do the same here. But printing trillions of dollar bills will help us avoid a toilet paper problem. I mean, talk about dual-use and recycling...it's a win-win-win." - illegitimate President Joe "you ain't Skidmark" Biden

THE ULTIMATE, TOP DOWN, AND CLEAR MATHEMATICAL PROOF REGARDING THE FACT THAT E=MC2 IS F=MA: Time dilation ultimately proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Time is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity ON BALANCE. Gravity is ELECTROMAGNETISM/energy. Great !!!! QUANTUM GRAVITY !!!! E=MC2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. What are the EARTH/ground AND the SUN are CLEARLY E=MC2 AND F=ma IN BALANCE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. BALANCE AND completeness go hand in hand. It does ALL CLEARLY make perfect sense. GOT IT !!!! THE SKY is BLUE, AND THE EARTH is ALSO BLUE. Great !!! Now, think about the man who IS standing on what is THE EARTH/ground. Perfect !!!!

@Joe Kunicki HOW AND WHY E=MC2 IS NECESSARILY AND CLEARLY F=MA ON BALANCE, AS ELECTROMAGNETISM/energy is gravity: Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. C4 is the proof of the fact that E=mc2 IS F=ma ON BALANCE. This explains the fourth dimension. TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=MA ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma. ("Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/energy is gravity.) The EARTH/ground AND what is THE SUN are CLEARLY (on balance) E=MC2 AS F=ma. TIME dilation ULTIMATELY proves ON BALANCE that E=MC2 IS F=ma IN BALANCE, AS ELECTROMAGNETISM/energy is gravity !!! (Gravity IS ELECTROMAGNETISM/energy.) The sky is blue, AND THE EARTH is ALSO BLUE. The stars AND PLANETS are POINTS in the night sky. E=MC2 IS F=ma ON BALANCE. Great !!! This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma ON BALANCE; AS ELECTROMAGNETISM/energy is gravity !!! It all CLEARLY makes perfect sense. BALANCE AND completeness go hand in hand. E=MC2 IS F=ma. The MIDDLE DISTANCE is thus balanced with/as the full distance (in/of space), as the stars AND PLANETS are POINTS in the night sky. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS ELECTROMAGNETISM/energy is gravity. Time DILATION ULTIMATELY proves ON BALANCE that ELECTROMAGNETISM/energy is gravity, AS E=MC2 IS F=ma. Indeed, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. (The sky is BLUE, AND THE EARTH IS ALSO BLUE; AND the stars AND PLANETS are POINTS in the night sky.) It all CLEARLY does make perfect sense.

We will never be able to isolate one. Photons are 2-Dimensional and can only travel in straight lines. 3 Dimensional spacetime can only be stretched/created in 2 dimensions Energy cannot reflect off of the spacetime border.
