I am suspicious of the complex mass object, but the math of Maxwell's equations and this approximate gravity are the same, so I understand the relation. I also wonder what the full E^2 = p^2 +(mc^2)^2 equation would be in this form.
@math.101
@math.101 15 дней назад
Suspicious is good ... E=mc² is still the expression for rest energy ... here I just make m complex ... thus, momentum would be also complex leading to E=ɣmc² , being ɣ the gamma factor and 'm' just a complex number

Oh wow wow wow wow wow! I am a physicist, I mastered in GR, I understand the duality property, I've happened at bivectors more often than once and every time thought, "uh, interesting thing, I should perhaps grasp the thing, it looks like it may be useful". The bivectors describe an area, and the Ricci tensor on the left side describes a constant volume, absent sources on the right; I felt a connection there. But the stuff like complex‒valued mass has always looked suspicious to me. I'm not quite comfortable even with the negative mass that pops up on the cosmological scale in the effective field on the right side. Your vid packs a whole hour-long lecture! It's a good thing that you rolled it so quickly that I went full 🤯, pausing and rewinding oftentimes. I'll be working on your presentation today, explicitly writing down all derivations, and I won't be surprised at all if I end up with a full notebook of the elaborated lecture notes. And I'm so very much not 30 any more… So true were saying the Romans that growing a beard doesn't make one a wise man: why didn't I pick up this tool for my toolbox before! Thank you so very much for this quick intro, I now understand how useful the multivectors may be!

The electrostatic force can be written as [Fe=(1/4.π.e)(Q^2/R^2).G/G=G.(Q/√(4.π.e.G))(Q/√(4.π.e.G)(1/R^2)], where mass M=∆Q/√(4. π.e.G) and gravitational force as [F=(G.M.M/R^2).(4.π.e/4.π. e)=(1/4. π.e)√(4.π.e.G)M.√(4.π.e.G)M(1/R^2)], where charge is equal to Q=√(4.π.e.

I mean, using E=mc² is kind of wrong, because we are always making the fundamental assumption that inertial mass = gravitational mass. The mass ypu talked about in the major part of the video is the gravitational mass, but the mass in E=mc² has nothing to do with gravity, but everything to do with kinematics, being actually inertial mass. That's why the final equation is so weird
@math.101

@@math.101 Firstly, loved your video 👏👏🎉🥳🥳🎉🥰😍 But that inertial mass = gravitational mass is the strong relativity principle, and is basically taken as one of the most fundamental axioms in physics. Yet, there is no reason why the relation is linear, or why it should behave the same in extreme situations. He did use it for Mercury's Perihelion, but, then again, he (and everyone else) used that for everything else too. Only in MOND's (Modified Gravity Models) do we see, sometimes, speculations around the violation of that axiom. Many experiments are all the time trying to see if there is any distinction between the masses. Obs.: m_inertial := mi, m_gravitational := mg mi = k*mg, through a neat change of variables results in mi = mg (technically they are quantities of different units, the inertial kg and the gravitational kg, with a conversion constant of 1 kg/kg) What physicists are looking for is weird stuff like mg=f(mi, v), with f(mi, 0)=mi

That's a good question, for one side the imaginary part of a vector is interpreted as a bi-vector which is often associated with rotations in the perpendicular plane, so it wouldn't modify the distance between the objects ... on the other hand that multiplication is similar to the Dirac quantization condition take a look here en.wikipedia.org/wiki/Magnetic_monopole which is associated with angular momentum ...but honestly, I don't know at this point 😊 ... yet I find the whole thing quite interesting ...

It's very elegant rolling those equations into one, but I doubt you'd have more insight in whats going on, if you'd be introduced to those forces in this form. Not sure, I was taught classical linear algebra projective geometry and Gibbs' Vector calculus, perhaps this formulation would be intuitive with someone who is trained in Geometric Algebra instead. It's kinda sad, when I was at Uni here was no one seriously pursuing Geometric Algebra, I wish the theory would have been part of the standard curriculum. It's time consuming and slow learning it on your own. Cheers!

These equations imply that magnetic monopoles would carry a mass of ~m_S (the Stoney mass), and thus a quantum field of said monopoles would have a maximum interaction distance of hbar/(m_S * c) = L_P /(srt(alpha_EM)) = ~11 Planck lengths. Such a small field interaction cross section implies the half life of such monopoles would be ~12 Planck times, which is highly unstable to say the least. Such a quantum field would get lost in the quantum vacuum foam if it exists at all

Эйнштейна мечтал измерить скорость поезда, самолёта - через опыт Майкельсона Морли 1881/2024 г., и только тогда, опыт будет выполнен для СТО больше чем 70%. Это возможно выполнить с помощью оптоволоконного ГИБРИД гироскопа. Вот исходя из выполненного более 70% опыта Майкельсона, возможно доказать постулаты: Свет - это упорядоченная вибрация гравитационных квантов и доминантные гравитационные поля корректируют скорость света в вакууме. Думаю получится совершать научные открытия; по астрономии, астрофизике, космологии, высшей теоретической физике,.. В итоге *увидите* теорию всего в простых ❤учебных устройствах.

How do you prove that black holes spin 3 times the velocity of light the other way relative to our galaxy the milky way. Otherwise it can't hold our galaxy. For example a flight is spinning at 1 Mac then to counter the effects you need 3 Mac the other way like breaking systems. 2 Mac to set it right and one for acceleration. Somewhat like 3 sticks to hold a heavy weight.
