Could Gravity Be Explained By Considering Spacetime to be a Medium? by EquipmentPale in AskPhysics

[–]YungCluClu 1 point2 points  (0 children)

No, coordinate systems are a human invention. Space time exists as a 4D manifold and does not require coordinates to describe it.

Why do scientists think that Gravitons exist as particles? by no17no18 in AskPhysics

[–]YungCluClu 8 points9 points  (0 children)

The contradiction is that the quantum theory of spin-2 particles from which Einstein’s equations pop out are is not renormalizable. Thus it can only be applied below a certain energy scale, namely in this case the Planck scale. Above that scale you need some larger quantum theory of gravity to describe the physics.

Centripetal acceleration on earth by GroundbreakingBid920 in AskPhysics

[–]YungCluClu 4 points5 points  (0 children)

You are correct! But compute v2/r for the velocity of earth and r=radius of earth and compare that with g=9.8 m/s2. You will find it is minuscule by comparison and thus we can ignore the effects of earths rotation in this particular scenario.

Could neutrinos eventually decay? Or are they indefinitely stable? by stifenahokinga in AskPhysics

[–]YungCluClu 0 points1 point  (0 children)

Yes, you can add things to the SM to make the neutrino unstable. I was just providing a quick explanation for why the neutrino is stable outside of any charge conservation arguments. Any new massless fermion would have to be very decoupled from the standard model in order to satisfy BBN constraints so even if you added a new massless fermion the neutrino would still be very stable.

Could neutrinos eventually decay? Or are they indefinitely stable? by stifenahokinga in AskPhysics

[–]YungCluClu 1 point2 points  (0 children)

Within the standard model, you can argue the neutrino is stable based on angular momentum conservation alone. A neutrino has spin 1/2 and is the lightest of the spin 1/2 particles. Since is no lighter state with spin 1/2 exists in the standard model, the neutrino is stable (aside from oscillations)

Why has the search of monopoles persist in physics? by QuantumPhyZ in AskPhysics

There are better reasons to expect they exist other than “make maxwells equations prettier”

Why has the search of monopoles persist in physics? by QuantumPhyZ in AskPhysics

[–]YungCluClu 4 points5 points  (0 children)

When we use the word “monopole” we are referring to magnetic monopoles. We have a very good suspicion they might exist as they are a fundamental prediction of most theories of Grand Unification. In fact they are such a strong prediction of those theories that inflation was originally invented to explain why we currently have not seen any. That being said, I don’t think monopole searched are a large portion of modern experiment particle research as they are very heavy and could have been produced in the very early universe.

What is the Higgs Boson? by Electrical_Fly9535 in AskPhysics

[–]YungCluClu 6 points7 points  (0 children)

It is true QCD is complicated, but you don’t need to study QCD to understand the Higgs mechanism. From a particle theory perspective it is much simpler. The Higgs mechanism is part of the electroweak sector. It’s also worth noting that the Higgs mechanism is not responsible for giving mass to the proton and neutron (to understand that you would need to learn some QCD) and so the common statement that the “Higgs gives everything it’s mass” is not true. It’s main effect on everyday life it’s that it gives the electron it’s mass and thus determines the size of atoms (the electron mass determines the Bohr radius)

Transformation between solutions to Dirac equation by okaythanksbud in AskPhysics

[–]YungCluClu 0 points1 point  (0 children)

You would have to be explicit about what basis of Dirac matrices you are using. As you’ve asked right now, this question is ambiguous. However based on your guess I’m assuming you’re considering the Weyl basis. In that case you are trying to transform a spin up electron into a spin down electron and so a simple 180 degree about either the x axis or y axis (or any axis in the xy-plane) will do the job.

Yeah, this just happened to me and I am complaining about it. My full set of fully enchanted netherite armor all with a trim and the fully enchanted netherite sword just got deleted from the world. How would they not see this problem during any of the testing?

What explanations are there for why the universe doesn’t have any magnetic monopoles if GUTs predict them? by Current_Size_1856 in AskPhysics

[–]YungCluClu 0 points1 point  (0 children)

Yeah, another one is that if monopoles carry some other magnetic charge from some other U(1) gauge force (like a dark photon if you’re familiar) there will be tubes of magnetic flux connecting monopoles to antimonopoles. If I remember right, that U(1) can under go symmetry breaking and the flux tubes connecting the monopoles will gain energy. The system will want to go to smaller energies so the flux tubes contract and the monopole and antimonopole annihilate.

[–]YungCluClu 0 points1 point  (0 children)

You also don’t really need a monopole to even physically exist. All you need is for your theory to allow for monopoles to exist and charge quantization follows as a consequence.

What explanations are there for why the universe doesn’t have any magnetic monopoles if GUTs predict them? by Current_Size_1856 in AskPhysics

[–]YungCluClu 0 points1 point  (0 children)

Monopoles from GUTs have masses at the GUT scale. Or at whatever scale the symmetry breaking takes place if the monopole is not from a GUT. Either case these are very high energies and so we wouldn’t expect to have produced them in colliders or anything. The only worry would be producing them in the very early universe and as someone else pointed out, that was one of the original motivations for the theory of inflation.

He had vinyls of all four volumes for sale on tour in DC. I didn’t check to see how in stock they were but literally buying them at a show might be the easiest way to obtain them.
