I will give you a soundbite : "A clock is an inertiameter" And challenge you to - understand it, - to point at someone who said this before, - try to falsify it by pointing at a process that is well understood, acts as a clock, and is not based on inertia. Should I bother to take her Shallowness out of my killfile ? I don't think so, I do not expect any worthy answer.

Oops! Another message from Hayek!
Did I forget to plonk him? Looks like I did. Oh, well, no time like the present. plonk -- Nospam becomes physicsinsights to fix the email |

We all know the endless discussions about one of the twins chasing the stars and coming back, about SR and Lorentz. We all know how imbeciles like you have the struggle of their life with it. Here is a "relatively" simple question, with two possible, simple answers. What would an imbecile like you who claims that "HIV does not cause AIDS" do with simple answers? http://groups.google.com/groups/sear...hayek+aids+hiv Crikey, he really does say that. Where do all these crazy people come from, anyway? That is actually a conjecture made a long time ago by peter duesberg, who is a well-respected molecular biologist _Formerly_ well-respected. His goofball view of Aids, which seemed to be based on reasoning along the lines of "It doesn't look like an ordinary disease caused by a common microbe so it can't result from any kind of virus", pretty much put an end to that everywhere except the lunatic fringe. Well, that is not really his argument. His argument is that the presence of HIV antibodies may be correlated with AIDS, but is not the causative agent. In effect, his view is similar to arguing that dirty surgical instruments are not the cause of infections - while it is obvious that dirty surgical instruments are correlated with a higher infection rate, unseen microbes are the cause, not the dirt itself, the dirt merely being an indicator of how likely it is that the microbes are present. It is still possoble to not get an infection with a dirty surgical instrument as well as get an infection with a clean surgical instrument, since there is a correlation between dirt and the microbes which cause the infection. Yes, that sounds like what I recall. Correlation without causality is what he claimed. The nagging question which arose was just how much "correlation" it takes before you are forced to conclude there's some sort of causality present, after all. I was following this somewhat more closely a number of years ago, when Duesberg was still taken seriously by a lot of people; at this point all I really recall clearly about it are my conclusions, unfortunately, not the details that went into them. I am not advocating his viewpoint since I do not consider myself enough of an expert on the subject to advocate either viewpoint. To argue either viewpoint without sufficient expertise would be to engage in the same crackpottery that litters this newsgroup (I also object to people who vigorously advocate accepted science like relativity if they have no idea why they are advocating it - the kookiness is advocating what one lacks the knowledge to discuss at the level of expertise needed to form an opinion. Point taken, and I'll shut up about it (after this post). [ ... ] I never understood why he was apparently admired in the gay community; the guy was toxic as far as I could see. I can't address that, since I was unaware that he was admired in the gay community. If that is true, it probably has a lot more to do with their desire to create a perception they like than for scientific merit. As I recall he was considered somewhat of a hero at one time. My impression was that it did, indeed, have to do with the fact that he was the only one in the scientific community at the time who was willing to stand up and challenge the mainstream viewpoint. This was long before there was any treatment for Aids, and may even have been before the western blot test was available; the only thing mainstream science had to offer victims at that time was the assertion that they must have brought it on themselves by their behavior (which is never a helpful thing to tell a patient). -- Nospam becomes physicsinsights to fix the email |

If a frame is splitted e.g. by launching of a rocket, then we have 2
frames. The "rocket frame" has changed his "state of motion". It's then clear whose clock is delayed. SR alone can't say this. So if we would know the history since BB we would be able to say more about all clocks, wherever they are. BUt does this lead us to new insights? Rudi |

Now go back and read what I posted, and try to answer the questions. It's then clear whose clock is delayed. SR alone can't say this.

We all know the endless discussions about one of the twins chasing the stars and coming back, about SR and Lorentz. Here is a "relatively" simple question, with two possible, simple answers. We have the earth move at 0.6 c through our galaxy, more precisely the earth moves at 0.6 c wrt the average mass distribution of the universe. I think you mean wrt the average momentum, not mass. Galaxus, one of the twins, is launched in a rocket, and accelerates away from Earth till he reaches immoblility wrt to the galaxy, more precisely : immobile wrt the average mass distribution of the universe. That's it. According to your viewpoint, will the Galaxus's clock run : 1 - slower than the Earth's clocks 2 - faster than the Earth's clocks Just an answer please, don't knows, can't knows please abstain. This is a bet, based on the predictive power of your pov, and we might never know the real answer. My bet is on answer 2 : faster. Uwe Hayek. The problem with your question is not so much the answer -- you could say #2, and find many good, even real, justifications for it -- but rather the problem of how you would determine the answer. Anyone who travels along a closed path relative to an inertial observer must, by simple geometry, spend more time at a higher "absolute velocity" than the inertial observer, which will cause his clocks to be behind the inertial observer's clocks when he returns. It is, to say the least, difficult to find even a theoretical method for deciding the issue. Phil |

"Hayek" wrote in message ... Martin Hogbin wrote: "Hayek" wrote in message ... Martin Hogbin wrote: "Hayek" wrote in message ... It depends on whether I am on Earth or with Galaxus. The two are in relative motion. You should know by now that Galaxus will measure the Earth's clocks to be running slow and observers on the Earth will measure Galaxus' clocks to be running slow. We are not observing : we bet on future results, after inventing FTL radio, for instance. There are two possible options : the third - undetermined - would be pure fiction, so I left it out. Science allows us to speculate between to possible options. And this question allows to nicely discern between the two camps : if there are still two camps : I got two, and including me, three votes for faster, and no votes for slower : the other camp just launched insults. It is almost as if they know they are beaten, and just leave the discussion room swearing. :-) The only theory of space and time accepted by physicists the world over is Einstein's theory of relativity. Science is not about authority and acceptance. It is about understanding and enlarging knowledge. Einstein himself said : "we should never stop asking "What If"." The answer according to this theory is as I have stated previously. I perfectly understand that answer, but it is just unsatisfactory to me. If FTL radio exists then relativity (as it is presently understood) is wrong. Not necessarily. Aether theory made us construct MMX, relativity theory will (maybe) make us construct the next step. Maxwell and Aether served their purpose, and we moved on to QM and relativity. It raises further questions, and we should pose these questions. In the previous century, physicists also thought there was nothing left to be discovered, that physics was complete. They were dead wrong. Let us not make the same mistake. It is an interesting line of thought : If ftl radio is discovered, what would the effect be on relativity ? What if we find a local experiment that allows us to determine our absolute speed wrt the average mass distribution ? I think these answers are already given by Lorentz and relativity theory today. I have been trying to explain all the result of relativity with physical effects, in a mechanistic way, and find it fits perfectly. Why explain a magical relativity, if it can be intuitively explained in a mechanistic way, yielding exactly the same results ? And in the process maybe opening the way to a practical experiment that will be the next big step in physics ? If you do not try, it will never happen. It is therefore not possible to answer your question using relativity on the basis that FTL radio exists. That is your opinion. Relativity is no straigthjacket, it is an assumption after MMX. I see relativity as something that tries to tell us about the true workings of physics. It is not the end of all discussions, but another beginning. Indeed, some people use theories as brain stoppers... |
