Now, I've said a lot here on how to see (or how not to see) how fast you "move". What I need to tell you now is just what I mean by that word "move". When I say "move", I also mean that you don't slow down or get sped up at any time, and that you don't veer to one side at all. When you move, you just keep all that the same as you go. How we say it is, you don't have any "pull". Why do I make a big deal out of that, you ask? Okay, let me tell you. Cast your mind back to Ari, from way way back when. He's the one who said that if you are at rest, you tend to stay at rest, and if you move, you tend to come to rest. He was off, you know, as he had no way to know that it was the air that has you come to rest. We had to wait a long time for Izzy to come by and say, "No, Ari: if you move, you tend to just go on and on. To come to rest, you need to have a pull." The air will give you a pull, a pull that has you come to rest. Then we also have the big pull, the one that says what is down and what is up, the one that has all of us in its grip. Izzy saw that this pull was the same pull that has the moon in its grip, too. I said that a pull can be a veer, yes? That is what the pull on the moon does. The moon has to veer all the time for it to stay with us. Were it not for that pull, it'd just go off in a line - no veer - and we'd just sit here and wave bye bye. Same with us and the sun. We veer, each hour, or else we'd get real cold real fast. But then, see, Izzy had to deal with the way that the pull acts. If a body has more mass, then it also has more pull, yes? That is why the sun is the axis we spin upon, and we are not the axis for the sun. But then why can't it go both ways? You take your ball of lead and your ball of wood and drop them, they land at the same time. But the lead ball has more mass, so it must get more pull. Izzy said, "Well, see, a body has one more kind of pull. This pull is such that it will want to stay put all the time. And the more mass it has, the more it will want to stay put. That pull is the 'a body at rest will tend to stay at rest' part of the deal. So you see, that pull and the big pull are in a tug-of-war, and they work out so that any mass will fall just as fast." I call it a new kind of pull, but it isn't so new: you feel it all the time. Get in a car and step on the gas - you feel a pull back into your seat. Let up on the gas a bit, and the pull goes away. Make a left, and you feel a pull to the side. Stop, and you feel a pull out of your seat as you slow down. Or, go to the fair and get on a ride. As you spin, you feel a pull out, away from the ride. You spin: that is to say you veer, and veer and veer and veer, just like the moon. If you had no seat belt, you'd fly off the ride, and you'd fly off in a line. (Well, that is to say, you'd fly off in a line as a bird sees it. To be fair you'd also arc down at the same time. But put that to one side.) Okay but now, see, old Al's big idea did not work when you look at pull. Go back to when you were lost in the void. You can't say if you move or not, yeah, but you sure can say if you have a pull on you or not. If you did, you'd feel it, no? Sure. So then you have no one true "at rest", no one true way to look at time, or mass, or size, but you do have one true way to look at a pull? Old Al said, "Erm. I don't buy that." We all said, "Aah, why not? Just give it a rest, Al." You can see why Al did not want to give it a rest, I bet. But this one was not such an easy nut.🏁
