I thought you already were world class .

Again, my apologies to all, including Phi. This didn't need to be public; I should have taken it to PM.

No. Markus will explain that gravity is not due to magnetism, or motions of opposite charges, or even mass. It is due to energy and momentum, that space-time experiences the curvature that is gravity. Particle and anti-particle pairs are created from the same energy, and annihilate, releasing the same energy. Energy which causes the same curvature and geometry of space-time which the particles and photons follow. Why would you think particles and anti-particles move differently in a gravitational potential ?

Sorry CharonY. I didn't mean to drag you into a long-running spat I've had with Phi. My previous post was meant for him; I didn't mean to turn it into a definition of Conservatism. It was a rebuke of assertions he's made concerning my political leanings/morals.

It's a known fact that if you're constantly on your phone while on a date, you're not getting any sex. Is that equivalent to infertility ?

Just the fact that you use 'Conservative' interchangeably with 'Republican' is worrying. Conservatives in Canada and Europe are more progressive than American Democrats. At least half of American Republicans are just plain nuts. The implication is that some of us who tend to be a little fiscally conservative are interchangeable with American Republicans. You have used that wide brush on me, a few times … And used perceived, or imagined, offense to unfairly lash out at me. ( bottom of page 3 )

Doesn't sound like a bad person. A little misinformed, and ignorant of what is actually happening, but just a regular Joe, with a few problems like many of us, who expects either a little help from his Government, or to get out of his way. There are many such people; liberal in some ways, conservative in others. That doesn't make them good or bad; what does is when unscrupulous, self serving 'leaders' and news organizations start feeding them lies, conspiracies, label them as one of their own, and introduce doubts about the 'other side', such as election fraud, QAnon, Hillary's eMail, etc. There were Conservatives in the 50s and 60s, and even the ones in the 70s and 80s were nowhere near as bad as what Conservatism, actually the Republican Party, has become in the US; Hell, George W Bush looks like a champ next to the current chump. This is a new phenomenon of the last couple of decades. And I fear a lot of Democrats, or Liberals, are falling for the Republican party/leader ruse. Just like they used 'fear' of Muslims after 9/11, they are using fear against the American people, the left fearing Republicans, and the right fearing Democrats, further sowing discord. If the Democrats fall for it, and hate all conservatives, America will never get past this. The answer is to approach any 'reasonable' Republican leaders that may be left, and working together to restore trust by the populace. Let them understand that the Government is concerned with the well being of the country, not simply staying in power. And shut out ( if not convict ) those Republicans who supported the worst President in American history If the Democrats start acting like the current Republicans, this will never end. In 100 years, Democrats and Republicans will still be blaming each other, like Palestinians and Israelis, living to 'avenge' the past, and doing nothing for the future. I notice a little 'understanding' in you above post, Phi. I'm glad you used a 'detail' brush, instead of that wide brush you usually use to describe Conservatives.

Vaccination is an exposure to the traits of a virus that trigger an immune system response, without the detrimental ( dangerous ) side effects. The 'flora' from human waste has been used to treat people whose digestive system is compromised because of its loss, but no, I wouldn't recommend manure therapy either. There are, however, studies that link eating dirt to better immune system, and digestive system health. Exposure to small amounts of detrimental stresses ( viral, bio, or unclean ) makes the body more resistant to those stresses. Unless the stress is large enough to kill; vaccines are obviously engineered not to kill. I remember reading that Mononucleosis ( kissing disease ) is prevalent among freshmen College students, because they go from their parents clean homes, to much less sanitary conditions in the dorms.

I mean that our bodies are adaptive biological systems; not mechanical systems. If you have a mechanical system, like a 5 hp engine, and you put a 6 hp load, or stress, on it, you burn up the engine. If you have an adaptive biological system, and you put a stress ( toxic, viral/biologic, radiation or even physical load ) on it, the system tends to adapt to that stress. The system ( body ) cleans out toxins. It produces antibodies to viral infections, and purges biological ones. Adapts o UV radiation with melanin and a suntan. Reacts to working out by getting bigger and stronger. Of course, if the applied stress exceeds a system's capacity to adapt, the system, or body, perishes. IOW, you don't get stronger by trying to do 2000 lbs bench presses; you die with a crushed chest .

I would consider a 'system' approach, instead of a 'self-contained' approach. There is little, if any, infrastructure for electric vehicles, so why does a vehicle need to be self contained and autonomous ? Why can it not pick up power as it moves from a distributed power system ? Consider a very small battery used just to get the car on the road's power grid, which could be built into the road itself ( electric streetcars are an example ). The initial outlay ( financial ) is way higher, but the rewards, such as reduced power consumption because you're not pushing around the large mass ( and volume ) of batteries, unlimited range once on the grid, and hazardous ( and limited supply ) refining and disposal of battery materials, may outweigh the financial downside. This is a new way of doing things. Why go with the tried and true; be bold. The world is always ready for a new 'mousetrap'. PS The flywheel effect is only good at constant speed,; that's why it's on the engine. If you are constantly accelerating your wheels ( like in city driving ), increasing their mass is detrimental. Oh, and 'thinner' wheels have less rolling resistance ( think bike wheels/tires, not Formula1 rear tires )

One example that could be cited ( although it has some 'racist' overtones ), happened in Canada about 20 years ago. In a little town, in Northern Ontario, Walkerton, several people died from contaminated drinking water ( bacterial contamination from cow manure run-off ). The person responsible for the Chlorination of the water was a drunk, who went several days at a time without treating the water, and the government had cut inspectors for the water supply systems. The joke I always make, is that if it was Mexicans living in Walkerton, no one would have died, or even got diarrhea ( Montezuma's revenge ), simply because in some parts of the world, we are used to having things too aseptic, while in other parts, their bodily systems are more 'robust' and adapted ( through exposure ) to biological and viral contaminants. My apologies to any Mexicans who might be offended by the above anecdote.

Not funny at all; kind of sad, actually. During lock-down, I've been watching the final season of that new show … The United States of America.

I hope the planned uprisings are just your pessimism, and the FBI preparing for a worst case scenario, INow. Hasn't that idiot, and the Republicans who still support his madness, done enough damage to American Democracy and ideals ?

Oh, I thought the reveal was going to show that Team A is Chelsea, and Team B is Man U.

Balances usually involve compromises. Where the options are not clear cut, but there is some ( subjective ) judgement to be made, someone will come along and 'pervert' that judgement process to favor their personal cause. If drug use automatically gets you a jail sentence, everyone caught with drugs goes to jail. If there is 'judgement' involved and 'circumstances', affluent white people don't go to jail; poor minorities do. If you're an idiot who listened to the President, and some Republican leaders, and stormed the Capital Building, you go to jail. The President will most certainly NOT go to jail ( for this ), but will probably get a multi-million dollar book deal, a movie, and an even more successful reality TV star career. And all those Republicans who supported him ( trying desperately to cling to power, while damaging the nation and democracy ) and encouraged the insurrection, will not go to jail, and will probably be re-elected.

Einstein vacuum is a classical concept; a volume that is still permeated by fields, such as gravity ( or rather, its geometry ). Quantum 'foam' was a concept, or description if you will, of quantum fields at very small ( below Planck ) scales, by J A Wheeler, and, is attributable to the HUP, with 'stuff' chaotically popping in, and out, of existence. Not the same thing, or different hierarchy of description, but rather, different models.

Liked Arnold's video, INow. Maybe he still has aspirations to become President, although even if he could, he's getting too old. He was somewhat contradictory though. At first saying we should not pledge allegiance to the President or the Party, but to the nation and its ideals. While finishing with asking people to pledge allegiance to President-elect J Biden. Chances are slim to none, but if he turns out to be an ass like D Trump, both parties should do what is best for the nation, and get rid of him. The 'old' way to 'control' platforms/businesses was with your money or patronage, JC. If you didn't like/agree with the service you took your business elsewhere, and if enough people did that, the business/platform failed. These days, it's all about liabilities, lawsuits, and trying to control others through legislation. I assume the Mercury you're talking about is the preservative, Thimerosal, Sensei., I've been putting drops in my eyes, containing that preservative, several times daily, for the last 25 years. And, other than the silver colored eyes, I'm still fairly normal. Aren't I, guys ?

Of course. Consider a map of the Earth ( 2 dimensional Cartesian ) with two ants at the equator. Both ants move directly North, they never meet, and there is no force between them acting at a distance. Now consider a different co-ordinate system, where those same two ants are on a curved surface, such as a globe of the Earth ( still 2 dimensional, but now just the angular part of spherical polar, or latitude and longitude ). The ants again move directly North, but this time, they get closer and closer together, until they crash into each other at the North Pole. And since they, like Newton, are not aware they're travelling on a curved surface, assume there is a force drawing them together, and acting at a distance. They call it gravity, but it is actually just paths along a curved manifold. That is what GR tells us. Gravity is not a force, acting at a distance, but simply paths ( geodesics, worldlines ) along 4 dimensional space-time.

Quantum foam is the vacuum ( or a description of it at very small scales, See J A Wheeler ). Quantum fluctuations arise out of the quantum foam, or vacuum, on 'borrowed energy which has to be re-paid back to the Universe after a time determined by the HUP. These quantum fluctuations manifest as virtual particles, which have measurable consequences. IOW, something from the vacuum. What did you intend 'nothing' to mean ?

The definitive Einstein biography is 'Subtle is the Lord: The Science and the Life of Albert Einstein'. It is written by Abraham Pais, a Physicist, and friend of A Einstein. https://en.wikipedia.org/wiki/Subtle_is_the_Lord As A Pais was a Physicist, before becoming a Science Historian, so the book does get quite mathematical at times. It is, however, very interesting, one of the best books I've ever read on the life and times of A Einstein, and it should convince you that E Hubble had no influence on the decision by Einstein to incorporate the Cosmological Constant into GR. ( maybe E Mach did; a little ). Beecee's account is more accurate. G Lemaitre proposed his Big Bang hypothesis after solving Einstein's non-static equations ( no CC ), after A Friedman solved them for an expanding universe. E Hubble had measured galactic ( actually nebulae, at the time ) recession speeds of 24 near galaxies in 1929, which turned out to be wrong by a factor of 7, because the zero-point calibration of the 'standard candle' used at the time.

Tell me about it ! Ontario started the second wave with large numbers in the Toronto area, but the numbers are now steadily increasing in most other areas as well. Just about every hotel room in Niagara Falls was booked on New Year's Eve These people weren't local, but everyone could book a room ( cheap winter rates ), get a wristband for entry, and then congregate together in one room to party. There were even stories of 'party' buses coming from Toronto. Now we're getting 4000 new cases per day in Ontario.

Australia ???? All the original immigrants to Australia WERE criminals. It was a penal colony. Just kidding ! Good to talk to you again, Beecee.

I am a BIG believer in free speech, however, I don't do any social media at all ( other than a few Forums, where I'm somewhat anonymous ). My rights to free speech stop when they start infringing on the rights of those who have to 'carry' my speech. So, yes, I agree that Facebook, Twitter, Instagram, etc., should be able to police or disallow content they find objectionable. If people don't like it, they don't need to keep using those platforms. The big problem, is that society has 'evolved' to use social media as their primary news source. Gone are the days when the News presented facts without opinion, and you made up your own mind about things. Now everybody expects to be force-fed 'entertainment' news and opinions. more and more, popularity ( on media ) determines whether the general public believes you or not. Presidents used to be chosen on their background, be it military, foreign service, economics, law, etc. Just in the last 40 years we've had a former movie star, and a reality TV star. What is happening to our society ???

Quick question for those who understand American Governance a lot better than I do. Now that Democrats control the Presidency, House, and Senate ( tie-break ), is it possible for them to change election rules and make elections a federal jurisdiction ( instead of State ), so that elections across the country follow the exact same rules ? Or is it a Constitutional issue, and requires a super-majority for a Constitutional Amendment. And while they're at it, address the 'big money' influence, and distribution of voting districts ( if not the whole Electoral College issue, and change to majority of popular vote )

You're seriously using my quote as an example of duplicitousness in my stance?! Are you saying these courageous patriots were just challenging the unjust laws that protect our national institutions, by arming themselves and breaking into the Capitol building? That's a pretty slimy way to argue, if you don't mind my pointing it out, MigL. Wow ! You got all that from "Phi for All replied" ? I said nothing else ! Where you get the duplicitousness and slime, I have no clue. But, if you didn't mean that those idiots who broke the law on Wednesday, should be able to argue it in court as to why it was the 'right thing to do', maybe you should explain and clarify YOUR post. If you don't mind my pointing it out.
