Magoo,

It will become too difficult to move this to a new topic if we continue here; so if we're going to do it, we must do it now. I'll await your opening the topic and transferring the initial message. Then I'll transfer my initial reply. Then we can both do the second round, one at a time, then you transfer your third message, and I'll reply in the new topic. I suggest the topic title "Infinity".

If you run into any obstacles, just drop me an email or post a short question on the MB. -|Tom|-

The solar cycle is 11.1 years. No one has yet succeeded in tying it to Jupiter's orbital period.

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>As to radar "soundings" of other inner planets to find the sun's true direction and gravity's speed, what does the observational evidence give as the number for this speed? The number which stands out in my mind is 2 x 10^10 TSOL. Or does my number apply only to binary pulsars (and other stellar binaries?). In other words, is the speed of gravity, or SOG (I distrust the term 'cg' which is an abortive confusion) constant and independent of mass, or not?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Each of the six experiments that measure the speed of gravity sets its own lower limit. The eclipse experiment is the least accurate, and lets a lower limit of just 20 c. The radar experiment sets a lower limit of about a billion c. The binary pulsat experiment sets the toughest lower limit, 20 billion c. Assuming all the experiments are valid, only the toughest lower limit matters.

The speed of gravity is no doubt a statistical measure, much like the mean speed of air molecules. But in that sense (as an average), it is surely "constant and independent of mass". -|Tom|-

The individual measurements which make up the average are wildly different. Why?

What would it take to set up a kind of amplifier or feedback loop involving an inner planet radar circuit, in which we could establish
an independently verifiable FTL two-way communication between, say, Earth and Mars (if Mars is considered an inner planet)? More specifically, how nonchalantly might we ask NASA for their RC Mars rover control codes?<img src=icon_smile_big.gif border=0 align=middle> I seldom use smileys, but by croikees I'm indulging here!

For the same reason air molecules all have different speeds. Physics theory predicts a Boltzmann distribution of speeds in such system.

Put differently, every time one graviton collides with another, the speed of each gets modified by some variable amount depending on how central or grazing the collision is. So the speeds of even single gravitons are being continually modified.

Where would the FTL signal come from? Radar travels at lightspeed, and the gravity between planets is too weak to measure its speed directly. The existing experiments seem to cover all the possibilities for the state of present-day technology.

I think the future of FTL SOG is in lab experiments. We are close to, but not yet at, the capability to do a convincing FTL laboratory communication with gravity. -|Tom|-

Infinity doesn't "validate" anything. It comes out of deductive reasoning as a logical consequence. To greatly oversimplify, if space has a boundary, what would be beyond?

quote from Van Flandern

Let's see. I am a total idiot but

If, on the average, the mass-density Pu is constant throughout the universe and the number of “lines of force” which come from infinity and terminate in a mass m is proportional to the mass m, then a sphere of volume V will enclose the average mass Pu x V. Thus the number of lines of force passing through the surface F of the sphere into its interior is proportional to Pu x V. For unit area of the surface of the sphere the number of lines of force which enters the sphere is thus proportional to Pu x V/F} or Pu x R. Hence the intensity of the field at the surface would ultimately become infinite with increasing radius R of the sphere, which is impossible.

Any comments from pushing graviters?

Remember, I'm a total idiot in these matters

Dr. VanFlandern, I have started a new thread with my posts above. The new thread is at www.metaresearch.org/msgboard/topic.asp?TOPIC_ID=156

Would you please go there and responde now?

Thank You!

Just learning!
Magoo
