It is interesting to look at the actual data for the anomalous acceleration. it is available at:
arXiv: gr-qc/0104064v5
What one sees is three distinct signatures;
(1) The effect gradually appears over a distance of about 5 AU or so reaching a maximum of about 10*10^-8 cm/sec^2 at 20 AU...
To all, I am wrong about the ambiguity. I was assuming that time dilation between two inertial frames was proportional to v^2 (energy). That of course is incorrect. However, this discussion was very useful to me in that I learned a lot about a number of things (including me). So I thank you...
Harald, yes you all have been most helpful and I appreciate it greatly. So far as my comment about "winning and losing", that was meant as a joke and the joke was on me. As I commented earlier in this discussion I am new to this mode of communication: This is the first time I have ever used a...
Everybody, You all win up to a point. I agree that for the last example I gave the issue is symmetry and neither the beginning acceleration nor the later acceleration matter by themselves. There are an infinite number of ways to have symmetric situations and the test of it ultimately occurs...
JessieM, Unfortunately you are doing exactly what I hoped would not happen: You are variously wrong in your statements and bringing in irrelevancies. Here are my responses:
QUOTE Do you mean "simultaneously" in the third party's frame? Or do you mean they are the same age when the signal...
Yes Harald, I do know about the relativity of simultaneity.
Let me narrow this myself and find out if you agree with me about the importance of history in a thought experiment. Here goes and I would appreciate answers about this scenario:
Two twins are located in empty space in an...
[Why do you say "three arriving ships"? You can see that ship C never moves at all in this frame, so if this is the frame of the landing site, C would just remain at rest parked there. Meanwhile A and B would both arrive simultaneously at the landing site in 2020, with B having aged less than C...
QUOTE Case 1 is ill-defined because they don't meet up again to compare ages, so what do you mean by "there is not time dilation between them"? In either one's rest frame the other one is aging slower, and is actually younger at any given moment. In the frame where they were originally at rest...
Please! If all of you would only deal with the SYMMETRIC cases where I say there is a problem, I could follow you all a good deal more easily. So, can we narrow this discussion somewhat?
I think collectively you are raising some interesting points but I am having difficulty relating them to my...
jesseM hey, let me read some about the relativistic doppler shift and see if I am wrong in what I am saying. At this moment I don't think so, but I'm open to changing my mind if needs be. for the moment let this rest. davidf32
So far as whether what I am saying contradicts either SR or GR, I don't think so. All it really says is that one should be careful as to how one uses equations: Generally speaking one has to know something about the circumstances of the observer and, in this particular case, some history of...
I don't think so.
Here is the experiment: Consider two observers in empty space at rest and close to each other. They both have on-board "instrumentation"
1. They agree to transmit signals using a finally controlled single frequency transmitter.
2. They accelerate away from each other...
Gad zooks! What have I gotten myself into?? I have to think this stuff through a bit more. This is the first time I have entered into this kind of discussion not face to face, and I have to think a bit more. At this point I am not convinced by any arguements any of you have presented, but let...
QUOTE: "There is no such thing as being at rest with respect to space. When we talk about a coordinate system being "at rest", this is just a arbitrary choice for convenience. we could just as easily define the clock as being "at rest" and the invidual as moving." END OF QUOTE
"Being at...
