Why Are There No Magnetic Monopoles? | Inflation and The Monopole Problem

[@dantodd2196]

Fascinating as always! Love these videos man!

[@ChrisPattisonCosmo]

Thanks my dude!

Poles are roots of polynomials. f(n)/f(n+1). If the roots are the same, two things can happen. A division by zero is one, a constant is the other.

[@douglasstrother6584]

Magnetic Monopoles are discussed in Chapter 6 of Jackson's "Classical Electrodynamics" (2nd ed.).

[@jimflask1164]

we also discussed it in our interview with an alien. what we've learned is beyond incredible.

Thank you for telling us about these phenomena of unsurpassed beauty and grandeur. I was especially struck by the fact that the area shown has the angular dimensions of a grain of sand at arm's length.

[@Salsadans123]

Good clear explanation, I've often wondered this. I don't find the "solution" really satisfying, as do the answers to other questions like the multiversa to explain our constants. The answer of science goes against instinct or feeling and that makes it difficult of course. I think that a theory that describes a number of things clearly and that makes a prediction that cannot be tested still has value, but it depends on how many predictions can be tested. In this case I know too little about it. I think a theory that cannot be tested has no value. In order for it to be valid, an effect will have to be observable in one way or another, indirectly. Otherwise, it's pure guesswork. Of course nothing is 100% certain and scientists should always make that clear. The aim must be for testable models, otherwise science will stop and philosophy or worse will begin.

[@ChrisPattisonCosmo]

Absolutely, if a theory cannot be tested against its predictions then it's not very useful, making post-dictions isn't enough anymore!

[@Salsadans123]

@@ChrisPattisonCosmo Perhaps as a thought that can then lead to a new insight. The sequel is, however, as you say, the goal must be to be able to test a new idea. The Higgsbosson was such an idea, but with an arithmetic proof. However, only because it could be demonstrated experimentally 40 years later (the possibilities to actually test that physically have only been worked out later) has the theory become indisputable proof.

Let ^ = inverted triangle symbol. Faraday said (a) ^e=p/e0; (b)^B=0. That (a) is divergent field and divergent field can produce mono or dipole field. While (b) is convergent and closed loop field cannot produce mono but dipole field. However Faraday Newton did not teach us about bar magnet and only electromagnetism.

[@ISleepWithAFanOn]

I'm super new to learning about monopoles, and since he's mentioning large monopoles, I have a feeling I'm off about this, but is it possible that the lack of monopoles could have something to do with the cooling of the universe? Maybe once atoms or quarks (not sure which might make more sense, if either) were able to form, the properties that would allow for monopoles to exist faded.

[@Achrononmaster]

It's a hack solution for sure. Magnetic and electric fields are fictions, "effective field" concepts used to describe elementary photon-electron (or any other charged particle) interactions. Feynman explained this years ago. The E/B duality is a relativistic phenomenon, essentially all B fields are due to relative motion. If there is no absolute motion then in an effective field theory you are not going to find a magnetic monopole. BTW: the "existence" of a magnetic monopole does not explain charge quantization, it is just a mathematical duality: if we invert coupling parameters then magnetic charge becomes like pre-inversion electric charge, and we have no electric monopoles, and magnetic charge becomes quantized. It is a simple topological argument.

[@beniendhartomulyana571]

I have derived the equation by combining Schrodinger's wave equation with the electromagnetic's equation, and find the monopole magnet field is the gravitation's field. The gravitation's potential energy that comes from the monopole magnet is = ((uo*q/(4*pi*c))^2)*((2*pi*c^3)/h)*(m/r). The ((uo*q/(4*(pi^2)*c))^2) is Planck length squared, so : ((uo*q/(4*(pi^2)*c))^2)*((2*pi*c^3)/h) is G. uo=4*pi*10^-7 c=speed of light q=electron's charge h=planck constant r=the distance from the particle to a point m=mass

"Certified smart guy" that was funny. He was one of those who started modern physics or quantum mechenics.

[@kevinbeaufeaux9140]

I have found a rock that appears to be a magnetic monopole. One side of a magnet is attracted to one end of the rock the other side of magnet is not repelled or attracted. Is this a monopole or not.

[@autodidacticasaurus]

Thank you for the thorough and concise review.

[@ChrisPattisonCosmo]

Thank you, Dr Bear!

[@enudiozayas5674]

i understand you, so easy explain, thanks

[@rich1051414]

If you have a bar magnet so large that the fields no longer apparently connect to the opposite pole, it would effectively be a monopole.

[@marspalk7611]

Well does theory predic magneti. Monopols? If magnetic monopoles are found if they exist, maxwell theory of electromgnetism has to be revised to fix have more generalised theory.

[@padraiggluck2980]

Unlike matter-antimatter pairs monopoles, if they exist, would pair up to form dipoles, or they would be attracted to magnetic poles of opposite polarity. They would follow magnetic lines of force down to the pole. If they exist they have all been captured. I think that if monopoles can exist in the wild they must be very rare indeed.

[@kevinbeaufeaux9140]

Yes I have a rock that is a magnetic monopole about one year ago.

[@jcw3195]

Seems like we are looking at our universe and seeing the Sun and the planets revolving around the Earth. Maybe it is time to re-think the space/time formula.

[@debyton]

So why didn't inflation also sweep away electric monopoles (charges) along with the magnetic monopoles in the early universe?

[@Flameprinz]

It's because electric monopoles are very low energy (i.e. low mass, e.g. protons and electrons), so they can still be created to this day. On the other hand, magnetic monopoles could, theoretically (as said in the video) be very high energy particles, so they were only created when there was a very high energy density (early universe).

[@jamesmatheson9624]

At -109 degree magnets become one pole

[@jimflask1164]

The problem with this "big bang" theory is that we do not see what we should expect to see. That is we should see stars in between galaxies and that just is not what we observe. Galaxies are not sucking into inevitable destruction at the center. Galaxies are forming out of the white holes at their center. The second thing we should see if the "big bang" theory was based in reality. Galaxies would not be on collision course. every galaxy is moving in every direction measurable. proving they each have origins somewhere other than a central point. We see young and old galaxies. This proves again that white holes and black holes work in harmony to equalize the pressure between our universe and the original universe.

[@SolutionsNotPrayers]

Looks just like Sheldon Cooper.

[@stevenrn6640]

My vote is there is no such thing as a magnetic monopole. There has never been a magnetic monopole and never will be.

[@johndawson6057]

That makes me very sad

[@haipingcao2212_.]

Why😂😊

[@RonnyAndersson-q9b]

Might be dead stars and blackholes. Go look there.

[@jdalton4552]

We will never find magnetic monopoles because they dont exist. There are three fundamental forces because there are three dimensions of space and time. Electrons are one dimensional motion . Magnetic motion is two dimensional and gravity is three dimensional motion. The strong and weak nuclear forces are hypothetical. Read my book, "The Physics Rebellion" to learn more.

[@martinstubs6203]

Magnetic monopoles? Today we know that magnatism doesn't even exist. It's all special relativity and electric charge. So why even talk about magnetic monopoles? No problem to solve, I'd say.

[@Kehvan]

Well, aren't you cute... and you only have 90 subs... so let me help.

[@ChrisPattisonCosmo]

Haha, thanks!

[@Kehvan]

@@ChrisPattisonCosmo no problem. I've always been fascinated about the possibilities and practical uses for monopoles... It's safe to say that's why the algorithm pushed your channel.

An absolute hack, not just a bit. Great video, though.

Haha, that's fair! Thanks though :)
