I thought this thread was about planetary defense against large asteroids on collision course with Earth. I never worried much about it, but it might be time to have a back-up plan. After all, Bruce Willis is retired with a form of dementia, and Ben Affleck is constantly drunk and in rehab. And I don't think Steve Bushemi, Billy Bob Thornton, Owen Wilson, and Michael Clark Duncan can do it on their own; even if Liv Tyler lends a hand. ( yes, it's a reference to the movie Armageddon 😄 )

Quite a few businesses that rely on min wage employees are still having difficulty finding people to work. I know of restaurants that have since closed on Monday and Tuesday, as well as for lunch, as they need available staff for busy weekend evenings. I remember Tim Horton's coffee shops closing in the evening for lack of staff, for about a year after lockdown ended; it has since gone back to normal. Most bars stay open till 11 pm, and only on Thurs/Fri/Sat till midnight, whereas it used to be 2 am closing. Fast food places, like McD, used to be staffed by young people after school/evening/weekend, now I see a majority of older retired people who used to only do weekdays previously. While CERB is not the cause, it is making the 'change' worse. I myself remember going to local farms, when I was about 12 to 15, to pick fruit like strawberries, cherries, peaches, etc. No 'self respecting' teenager will do that now, and the Government has to subsidize foreign workers ( Mexicans, Jamaicans, etc ) to help farmers pick their fruit. Is the Government going to have to subsidize foreign workers to work in fast food restaurants and bars also ? There was once a 'stigma' associated with handouts ( welfare, panhandling, etc ), now it is expected, as witnessed by the large numbers of young panhandlers. Handouts ( like CERB should be there for people who cannot take care of themselves, for whatever reason; not for people who don't want to take care of themselves. And Ontario's min wage is $16.55 ( going to $17.20 in October ); of course that is in our 3/4 dollars. I'm starting to get the impression that 'somewhere in the Americas' is actually ( or, used to be ) in Canada, as you seem to know a lot of stuff about Canada most Americans would not. Not that that's a bad thing; arrogant Americans should know more about us 🙂 .

In this 'transmission', no energy is gained by incorporating magnets, and you would be better off using simple gears. I don't think you understand what the magnets are doing in your design. They are simply used as a force generating mechanism, as would be the teeth of gears. One big difference is that this force is limited by the strength of the magnets and the geometry of the magnet/finger system, as opposed to the the tensile strenth of hardened steel, which limits forces in a gear system. IOW, at best you have the same frictional losses in your system so you will always get less output than input, and the amount of power you can transfer is severely limited by the magnetic coupling. ( I tried to be as nice as possible and gave a serious response, without laughing )

We had a package during COVID also. Our Government paid people $2000 Can per month to stay home. Now, our economy is still struggling to recover, because small business can't find people to work, and the Government has a crap-load of debt that is still fueling inflation. But it's not like you guys don't have your problems. No doubt, if D Trump manages to get re-elected President, he'll be telling everyone how well the economy is doing under HIS Presidency.

I don't like Dimreepr's analogy, but I'll try to use it. Picture yourself living on that salt flat, which is level as far as the eye can see, and seems to go on forever. You start walking in one direction ( at a great speed ) and eventually you lose sight of the salt flat, and run into mountains and forests. Even cities and bodies of water that you have to swim across ( again at great speed ) until eventually ( after quite a while ) you come back to the same exact spot on the salt flat. But from the opposite direction. Clearly the surface of the world is finite; but there is no boundary. So where is the center of the world's surface ??? Now ( and this is a big step ) extend your thinking to 4 dimensional intrinsically curved space-time.

It is not the size that is revolutionary, rather the approach used. The American Government has chosen to reward industry for switching to low carbon emission processes. Most other country's Governments ( our PM in Canada also ) have chosen the stick approach, subjecting small industry to punishing carbon taxes, which keeps them from making the changes to low carbon processes, and the vicious cycle eventually drives them out of business. It is this far-sighted thinking that allows the American economy to perform much better than ours.

Rookie mistake. There is no such thing.

I just knew pyramids were going to be involved ... Now you've included picture salad ( not topology ), but still no meat.

I think you need to discuss this with @Maartenn100 . He claims there is no past. At least one of you must be wrong. I'm going to edge my bets and say you both are.

If you repost, try to use less word salad in your WAG. We like a little mathematical meat with our dinner.

Philosophy that ignores science is a Lewis Carroll 'rabbit hole'. And you know what they say of people who assume ...

Even what you consider moderate to highly 'plausible', is not. Never mind that last one concerning 'consciousness'.

I'm not well versed enough in QFT to know whether those fields have coefficients in the same way. Or they may be just defined as 1, as is the index of refraction. Keep in mind that permeability refers to the magnetic field and permittivity to the electric, and, since both have units, with a suitable choice they could both be set to 1.

True. All the fascist labelled states, Franco's Nationalists in Spain, Mussolini's Fascists in Italy, Hitler's National Socialists, and even Peron's Argentina, as well as Stalin's communists in Russia, Pol Pot's Communists in Cambodia and Mao Zedong's Communists in China used the same 'actions'. They were better classified as strong dictatorships where dissention is not tolerated, and results in death. The labels have no meaning because, even when you have a popular uprising to protest oppression by the wealthy few, as in the French Revolution, it soon descends into murdering chaos. It seems we humans only know one method. Instead of discussion to gain consensus, we choose to silence opposing ideas; in the extreme cases, mentioned above, by eliminating the people with the opposing ideas.

Those coefficients define ease or effort for radiation to pass through that medium ( or lack thereof ). For example, when we say the index of refraction of free space is 1, as opposed to glass at 1.5, is n=1 a property of space ? Or is it a lack of that property.
