Yeah, I know what you meant. It is the use of the instrument that matters, even a 'lowly' Casio.

Particle spin is intrinsic angular momentum, and any momentum is a 'source' of Gravity. Is that what you meant ?

Music is not an instrument; it is a composition. You would be surprised what a former member of Depeche Mode could do with a Casio in 1982, along with Alison Moyet. And then, 40 years later, with an orchestra ...

People have believed much more weird ideas. Even that an egotistical, but insecure moron can be voted in as President, and he will do what's best for the country.

Time always passes at the same rate in everyone's own frame. However the very fact that expansion increases the time base of an emitted light signal, resulting in red shift or a 'stretching' of the signal's wavelength,, means that relational time between distant events will vary. this effect is not due to gravitational effects because, as you say, global curvature is very nearly flat.

So, we're not going to see a Trump beachfront resort in Gaza ?

You realize that Galactic North and South are purely arbitrary distinctions ? It is an accepted convention that keeps everyone 'on the same page'.

I can see such a need for places where young people need to move away from their elderly parents ( as has been mentioned about China, and Southern Italy which I'm familiar with ) in order to find employment, but why are their families abandoning their parents, or sending them into retirement homes in places like the US and Canada ? Parents deserve better than an app; their families should care for them.

Ahh, fond memories of Hollerith pinch card machines from the mid 70s. And a stack of cards about 6 inches high, each with one line of FORTRAN IV code, solving for the energy levels of the Helium atom by numerical methods. Tedious and frustrating, but I would gladly do it every day again, if I could be 21 years old again.

My app would activate every few days. I'm at work 12 hours, for 7 days every 2 weeks. Actually closer to 13 hours counting travel time. Most phones have 'health' apps or motion detectors; if no activity is detected by the phone in 12 hours, it should message your contact. Then again, I've been known to sleep for 12 hours as well ...

I thought Klein-Gordon was virtually un-useable, and the Dirac Equation replaced it. See here ... ( since you like his videos also )

From a QM standpoint, if all motion ceases at absolute zero, quantum particles have no momentum and their position is fixed. An impossibility according to Heisenberg. In Quantum Field Theory, this video does a better job than I could of both, QFT fundamentals, and minimum allowed energy. ( and I like his videos )

Energy prices have shot up ( along with everything else ) under the leadership of His Orangeness. In Western New York, and others on the Eastern seaboard, they buy Ontario's and Qjuebec's surplus Hydro at tariff-free, reduced prices. Swansont, and many others in Western New York, didn't vote for Trump, and I feel for them otherwise, I'd say "cut off their Hydro'. ( we can't do that anymore with our oil, because now he's stolen Venezuela's reserves )

And how does entropy reset itself when everything collapses to the same temperature ? Will it need to have a quantum fluctuation restart the cycle ?

😃 😄 🤣

Saaw CotG in the late 70s ( my teens ). Sure, I was a skeptic also. But it did make me think. Thank you E VD.

He is also signaling regime change in Iran. Trump and his 'minions' have said that the Ayatollah is looking to leave ( or be killed ), and that the US will protect the protesters. Meanwhile, in the USA, his DHS is shooting peaceful protesters in the face. Give that some thought ...

Some sedimentary layers surmount while some subside according to the geology of the mantle in that location. So I guess the answer is "It depends".

But when human judgement is also non-sensical, crazy, or stupid, neither one 'corrects' the other; you end up with double nonsense, crazy and more stupid.

Newton also dabbled in alchemy. How did that work out ? I guess we're all human, and even geniuses have their faults.

Including the nonsense, crazy, and stupid. The danger is some of us can't discern that from valid information. You know, the kind we used to get from books, which had undergone a vetting process to validate any contained information.

D Trump is now doubling down on his intent to take Greenland, the easy way, or the hard way. One of the channels I regularly follow ( mostly for military interests ) is M Shurkin's Pax Americana, and he took a very balanced approach to D Trump's invasion and abduction. He states that everyone should be glad that Maduro is gone, but that a dangerous precedent has been set, which will lead Trump to pursue objectives ( like Greenland ) which shouldn't make anyone glad.

My thoughts are already fairly 'scattered', I certainly don't need Grok to add to the confusion. ( It would be like trying to work on a problem with E Musk whispering nonsense in your ear )

Or three, or 4, or 5, or ... Or an infinity, depending on how many different observers/interactors there are.

It seems like everything that affects people, during the last 5 years, in a way that makes them ill, gets blamed on the vaccine. One younger married guy I know, was ill during the last couple of years. He was a big guy, and he lost half his body weight, but had recently recuperated, and was back to normal. Just the other day someone told me he had committed suicide ( by hanging ) and suggested it all stems from him having had 4 Covid vaccines that had messed with his body and his mind. I just took in the sad news and didn't even bother to engage/correct him.
