    You've been explaining the recent happenings in the world of physics to me since I was a 12 year old boy. I'm now a 23 year old man with a bachelor's in physics and I feel even further from my dreams of contributing to experimental or theoretical physics in any significant capacity. I'll see you in a few years, hopefully with a PhD. :)

      If is too difficult to make a contribution to experimental physics, why you do not try theoretical physics? The fact is that in the last 100 years there is no significant advance in the understanding of the fundamental elements as - What Energy is; What Electromagnetism is; What Time is; What Space is...Anyway, they are looking for a new physics, which can unify QM and TOR. Why you have not read my book - "Theory of Everything in Physics and The Universe"? It is possible that there you can find an idea for your great theoretical discovery, which will make you a great scientist. You will never succeed if you never try!

      Earth's gravitational waves contribute positively to the spin and kinetic energy of fermions. For this reason, since the muon is heavier than the electron, the muon has more magnetic power than the electron. Different laboratories around the world produce different results due to the different 'gravitational acceleration'.
      If the experiment were carried out in space, it would probably give the same result as the theory.

    In the expanding graviton model, gravitons are always coming into existence, expanding from a point, and overlapping. When large numbers of expanding gravitons overlap, they inevitably create the geometries for particle-anti-particle creation. When gravitons overlap and create the geometries for particles/antiparticles, that's the same as creating virtual particles.

      If it did appear with a fixed period, that would define a universal rest-frame in spacetime (the frame that minimized this period): therefore it doesn't. It's natural that one would get relativity violating ideas from the "pop-in-and-out-of existence" model, since it implicitly chooses a reference frame.
      It's a semi-classical description anyway: both the quantum vacuum and the muon's cloud are constant, they do not change: it's always the same, observables do not evolve with time. All the "fluctuations" exist in a quantum superposition, unchanging and always the same for every muon in existence, no matter your inertial frame.
      (The frame thing is important: you have particles popping in and out of existence with zero average momentum, no matter how fast your are moving. Think about that for a bit).

    Really great video, especially to get context about the experiments in fermilab
    If I may, I just have small "advice" : (Idk your budget, and I really mean well, we need more educational videos, especially on quantum mechanics.
    If the green screen is not used, you can maybe used a set, with half the screen for the key points.
    A little bit of cuts in the editing, I'm amazed that you can get a lot of these script without cuts, but it can add a bit a rhythm in the video, less breathing noises.
    Microphone aren't cheap, but it peaks a little bit to much, I think the clip on mic doesn't help
    The lightning is bright, which maybe necessary because of the green screen, but it seems that the light is not diffused, or not enough.
    I don't know if you'll se this comment, but please keep posting, those small notes aren't that important. I'm just nitpicking about details.
    A lot of science channels use green screen with a space background. Some onsite set can boost the production, especially for fermilab, it would be so great !
    Btw your generic is AWESOME ! Great production, seems legit.

    FINALLY! I'm like "Where's my Fermi Dude?" I need a breakdown... in the upside, I've been briefed.

    he said the space by electrons is matter and anti-matter separating and recombining? like little antimatter explosions? is that where force and physical matter comes from? the force of these tiny micro explosions happening everywhere? is that why a seemingly empty atom has the illusion of spatial dimension? because of the force of these explosions?

    like charged objects repel eachother, we can determine the quantity of force, however HOW does it work?what is the mechanism? is it known by science? i gather streams of photons are the communicating units, is it perhaps the interaction of the coliding photons creating a hetrodyne effect with peaks and troughs and thus pressure differentials? HOW do charged objects repel eachother?im not seeking the 'quantity of force calculation, but rather the explanation of the mechanism.

    I'm def more of an aspiring theoretical physicist, I can swim those waters fairly well, but you experimentalists always blow my mind with how you go about falsifying or confirming ideas.
    This was such a smart way of looking for new physics...I'd have never thought of that.

    I would be most curious as to how the lattice calculations vary with "grid size". For example, if calculating on a slightly smaller grid moves the computed g-2 value away from the experimental measurements (toward zero, say), then one might reasonably surmise that calculating with a substantially larger grid would result in a g-2 value even closer to the experimental value(s). [The decades old dream of doing very accurate tau precession experiments may re-emerge, probably still remaining a dreamy dream.]

    Also, there is a muon g-2 experiment set up at JPARC Japan, with different methods and storage ring as compared to BHL and Fermilab. It is planned for its first run in 2024.

    The addition of Lattice QCD to the calculation seems to account for only roughly half of the discrepancy (and still doesn't make the error bars overlap), so something else must be also going on.
