That was not your claim. What was my claim about gases? Your claim was - 'If all matter expands, the way gases do,' Very simple considerations indicate it is nonsense eg for your claim to be true since gasses are made of particles which, if your explanation is true would need to be made of gasses, which ............ in a turtle all the way down type explanation. All the evidence we have is electrons for example are point particles whether you wish to acknowledge it or not. Rest of rubbish snipped. Bill |

Simply more kooky nonsense. Acceleration has a well defined meaning in physics as rate of change of velocity. Or rather well defined in Newtonian mechanics. Physics changes quite often. And velocity also has a well defined meaning - rate of change of position. I seem to remember a well accepted theory that predicts traveling 10 light years in one year at .9 c. 10 light years as seen in one frame, divided by 1 year as seen in another frame, is not defined as velocity in that theory. Perhaps you are alluding to a theory that defines velocity as a distance divided by a time, when both quantities are expressed in the same reference frame. Exercises: According to this theory, supposing that the distance I cover as seen by you is 10 light years and that our relative speed is 0.9c, - how long would it take me to cover the distance as seen by you? - how long would it take me to cover the distance as seen by me? - what would be the distance that I cover as seen by me?

I had the perception that you embraced General Relativity, but if you don't like the idea of time slowing, I must have been wrong. Stick to the usual meanings and you may be able to get somewhere. Rest of rubbish snipped. Bill Good advice, never try anything new, just do the same forever. Joe Fischer Acceleration is not always acceleration. Observer in a free-fall does not feel any acceleration. Logic is not always logic. Illogical statements are not logical. Is that logical? |

I will try one more time. Do you know why gasses expand? You claim to be looking for mechanisms. Do you understand the mechanism behind the expansion of gasses? I think so. Then describe in plain English why gasses expand. If gasses behaved they way you claimed, the would spontaneously and continuously increase in temperature. This does not happen in the real world. Well, obviously you have a poor understanding of what I proposed, or you have a wild imagination. Do you mean if they are contained and expand, causing an increase in temperature and pressure? If so, don't worry about it, the container is also expanding, so the temperature and pressure will remain constant. You are just confusing yourself now. Gasses do expand. We can measure and observe that. A gas will spread out to fill whatever container it is. Containers do not expand. Even according to your model we would not observe a container expanding. However according to your model we should observe gasses expanding, because we in fact do observe them expanding. So once again, why do gasses expand? If you answer that, think about what would be necessary for a gas to double in volume at a constant rate. This is very basic and intuitive stuff. Stephen |

What unexplored experiments? Do you honestly believe that two "balls" of gas of different sizes would both "expand" and double their size in the same amount of time? I do, but why not ask a physicist, this is something that can be tested. You really need to learn some physics. Too late, the moron syndrome has already taken him. Do you know why gasses expand?

He doesn't really mean this... You apparently have no real interest in understanding gravity No he doesn't, he just wants others to vindicate his moronic dementa. as you apparently have no interest in learning anything about physics. Try figuring out how gasses behave in the real world and why. It is not that hard. Let's go with the idea that the surface gravity of the Earth is due to an outward increase in it radius r. First, as can be seen & tested, a = v^2/r And v is the radial expansion velocity dr/dt. Given that for any time after some arbitrary instant where t = 0, r is initial, we must have, r(t) = r + at^2/2 In order for the expansion theory to work, at least as far as I have been able to determine given the sketchy descriptions, objects must expand at an exponential rate. Everything must double in size at the same rate in order to maintain the illusion that everything has stayed the same size. So r(t) must[1] look something like r(t) = R * E^f(t) where R is the "initial" radius, E is the expansion rate, and f is some increasing function. Suppose f(t)=t. Then the acceleration at the surface of the Earth would be r''(t) = R * ln(E) * ln (E) * E^f(t) This is in "real" meters and "real" seconds. Because the meters we measure are also increasing at the same rate, the acceleration we would measure is a(t) = R * ln(E) * ln(E) Note the dependency on R. No matter what we use for f(t) there will be this dependency on R. So according to this strength of gravity is proportional to the radius of an object. However, the moon's radius is 1/4 the Earths, but its surface gravity is 1/6 the Earths. So there is no need to introduce anything as sophisticated as relativity to find a contradiction. Just explaining the fact that surface gravity is proportional to mass and not radius seems to be impossible. Stephen [1] I suppose there might be some convoluted for the "real" radius over time that avoids this problem, but I can't see what it might be. |
