Will do. Cheers, Mate.

Ed, What you say is mostly true for other cars. But this one is, in fact at the very hub of existence. The rest of the universe does move but not as you suggest with Earth revolving and orbiting Sun. The Earth, being so close to my car, can't possibly move that much. Picture a pizza baker whirling the dough. The further from the center the faster it moves with respect to the center. Captain, Thanks for the lesson in socialization. It is all too clear from your post that you are indeed the expert.

My car is unique. It was designed to a price and assembled by UAW workers. It is not the fastest car. It doesn't have the most comfort, interior space, or best brakes. But it does something that no other car has ever done and no other vehicle, for that mater, can do. It sits perfectly still at all times. You may think that a car that doesn't move would be a bad thing. Most of the time you'd be right (given a particular frame of reference). But even though my car does not move itself, it remains in one point in space-time and shifts the entire universe relative to its location. So while my car sits at the very hub of creation its engine. drivetrain. and wheels then exert a force that causes the next desired location to become closer and closer until the place arrives under my car and I get out. Too bad you can't have one too. But if you are ever brought near to my car as the universe moves past I'll wave!

http://en.wikipedia.org/wiki/Ship_of_Theseus Perception is determined by perspective. Originality can mean different things to different people in various circumstances. The late Boyd Coddington committed a type of fraud in this area by registering newly crafted cars using the VINs from rusted junk to avoid taxes and modern safety and emissions regulations. So from the perspective of the state of California the cars were not originals. Conversely, in the age of sail, insurers were all too happy to allow a completely overhauled ship to take the place of an aged one on an agreed value contract. The risk went down for them and the owner so both parties benefitted.

If the barycenter is within one object then the two objects don't orbit each other. The example of the Earth and the Sun has the barycenter well within the Sun. In the Earth-Moon system the barycenter is within the Earth. In those examples, therefore, the Earth orbits the Sun and the Moon orbits the Earth. The Sun doesn't orbit the Earth "a little".

What I know: Nothing. What I suspect: The Sun is busy making helium by fusing hydrogen. Question 1: Is the hydrogen in the Sun mostly protium? Question 2: Which isotope of helium is most often created by the Sun? Q2A: Are neutrons being created? The mass of the produced helium is less than the mass of the hydrogen that went into its creation. Therefore, the Sun's total mass decreases over time as hydrogen is fused into helium. The average diameter of the Sun is a reflection of the balance between the gravitational attraction and the explosive force of the energy released from fusion. In absence of fusion, gravity would compress the Sun into a much smaller sphere. In absence of gravity, the fusion would blast the Sun into a thin cloud of expanding gas. It seems to me that the Sun should be growing in size as it loses mass. Question 3: Is the Sun growing in size? When the Sun's hydrogen is all consumed, the Sun will then begin fusing helium into carbon. The carbon will have less mass than the helium that went into its creation. The Sun will again lose mass and grow in size. Question 4: As the Sun enters the red giant phase of its life, will it grow smoothly to its new size as its mass decreases or will it be more like flipping a switch? (This sudden expansion is what is depicted in graphics shown on some TV "science" shows and it didn't seem right to me that the change could be so sudden.) ______ Question X: What happens to the relatively small amount of heavy elements that the Sun has captured since its formation? If you could freeze time and look into the core of the Sun would you see its collection of heavy elements in some molten pool? plasma? gaseous state? Just what happens to a mostly iron meteoroid that falls into the Sun's gravity well?
