I can't believe it. I caught Feynman saying something wrong. The movement of oceans due to tide would cancel out, so it can't gradually slow down the speed of rotation of the Earth.

@ayyleeuz4892 May I ask a second question? Are there planets without oceans whose rotational speed doesn't slow down? For example, has the rotational speed of Mars remained the same for eons?
@PK-tc2uq Жыл бұрын
@ayyleeuz4892 Sorry to be a pest. I visualized your detailed explanation, and I have the following concern. The ocean bulge closest to the moon ought to be larger than the one on the opposite side. If this is true, then there should be the kind of effect you probably saw in your physics class, where a student sits on a chair whose seat rotates freely while holding a weight in each hand. The professor spins him and each time the student extends his arms his rotational speed slows down. Similarly, if more water rushes to the bulge closest to the Moon than forms on the opposite side, wouldn't that slow down the angular momentum?
@PK-tc2uq Жыл бұрын
@ayyleeuz4892 I think the two perfect bulges cannot form because on the far side the effect of gravity is lesser, and if as you said it's a result of inertia, then some of that momentum is lost in all that water moving to that point. So the differential (or better yet the continuous formation of that differential, analogous to the physics student extending his arms) between the two bulges' volumes is what slows down the earth. The friction of water moving might also play some role.

OK, he discusses why laws aren't reversible. And we can discuss this in various ways. But let's say they actually found that the laws may be reversed, how would we do that practically? Electrons spins around the nucleus. How could we create an artificial haven where they spin backwards? It is a simple fact that real matter actually behaves in a particular way. How could we persuade it to go the other way? So, this kind of thinking is just a sandbox for our minds to play with. The reality is what it is, like a terminator. You can't argument with a terminator. We humans are the product of the real matter. How could we turn the reality that forms os in the opposite direction?

Feynman's lecture is based upon an erroneous assumption that time is a real entity. In fact it is not only intangible, but also imaginary, an invention of mankind for convenience of daily living and mathematics. The more fundamental concept is that all exists in the ever present "now", and that motion in space is indeed the more fundamental characteristic quantity. That is, the accepted definition of motion (velocity) that has come to be accepted is v=d/t (or velocity equals distance divided by time). The more correct way to view this is that time is DEFINED by distance and velocity: t=d/v (or time is defined by an item moving through a measured distance.) This may be the balance wheel of a wristwatch or the rotation of the earth. Thus it is completely a man made construct and has no physical reality. Past and Future lose meaning. Think about it.
@andrewhanson5942 Жыл бұрын
@ayyleeuz4892 Well thanks for reading my comment and giving me some feedback on it. Most folks can't wrap their heads around the concept at all. Time being a real thing is too firmly entrenched. Distance or displacement; all seem like pretty much the same thing to me. And I can SEE and interact with those. Time I can only sense by the motion of objects within space.
@andrewhanson5942 Жыл бұрын
@ayyleeuz4892 True, without velocity of some sort there would be no way to perceive displacement. So perhaps it is simply my personal preference to assign velocity a higher reality than time. I find it more intuitive to think of, for instance, velocity slowing down in an extreme gravity field than to think that time does the same. So does time actually stop inside a black hole, or do the vibrations of molecules simply cease under that gravity extreme? Either way, same result. And in my experience, the simpler the explanation the more accurate picture it portrays. Thanks for the chat.

This was not Feynman's finest hours. The whole notion of reversibility needs to be explained before he can use the example of the plenet and the sun. And then he would be wrong. It is simply not reversible.

An alternative to the past-present-future model is the eternal present. There is only the present moment - only the present exists - only the present has that status - in which things move and change (or appear to do so), and it is eternally existent.
