We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Funny concept. The force of gravity looks and acts in lots of predictable ways that are vitally important to us and can be calculated and predicted and used. But is it "really" there? What can such a question pretend to mean?
PS, "Now, what I just said sounds preposterous and maybe even moronic, but it's not sophistry." He's referring to the idea that Einstein insists we have to consider that the Earth is falling up toward to the apple, instead of the apple falling down to the Earth. To which I can only reply, "Pooh," or "Yes, it certainly is preposterous sophistry." I can't see why Einstein would have had a preference for either one; they're accelerating toward each other.
Also, what's supposed to be the difference between calling it a "physical" force and calling it something else? It has a "physical" effect, which is what we care about.
But the video of the helium balloon in the accelerating car was cool.
The air gets awful thick with smug scientism these days. It's useful to be reminded that we are susceptible as the ancients who believed a flat earth was the center of the solar system in assuming the physical world must operate according to our prejudices.
If this were true we would not register weight on a scale. Since neither we nor the planet would move in relation to each other. Everything would be weightless and gravity would not exist. The planet could not accelerate towards us any more than we would accelerate towards it.
