Measuring sun's true direction

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>I am not argueing the points posted above but rather the triangulation of the two locations of the sun. The real time location triangulated with the light or apparent location. This just needs the exact angles to determine the speed of gravity since the speed of light is assumed or given.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

I don't see how. Feel free to elaborate, if you can. -|Tom|-

The light of the sun comes from one place and the gravity focus is in another place 20sec of arc away. The speed of light is given and so is the distance to the sun. If light speed and gravity were the same this angle of 20sec of arc would be zero and if the gravity was twice the light speed the angle would 10sec of arc. So it seems that if the angle was measured accurately the speed of gravity would be apparent in the ratio of angle to the speed of light. The closer to 20(or whatever the maximum angle is) the nearer the speed gets to infinity. As a bonus the change in the angle over the year period of Earth's orbit will clearify another issue in the mix by providing data as to the distance to the sun.

Using your procedure, if we measure the deviation of the Sun's gravity from the focus of the orbit, that would be zero for infinite speed of gravity, 10 arc sec for something traveling at twice the speed of light, and 20 arc sec for anything traveling at the speed of light.

Then the six experiments set different limits on the deviation from the focus. The weakest experiment (eclipses) sees a deviation of zero plus or minus one arc sec. So the speed of gravity must be at least 20 times the speed of light, according to the eclipse experiment. Stronger experiments set much tighter limits. -|Tom|-

If the light of the sun is delayed 500s the true direction to the sun is 20 sec of arc in front. That is if gravity is very much faster than light. If gravity and light are the same speed the angle is zero. At 20 sec of arc the speed of light is infinite and instintly felt at the given distance of ~1AU. This is a simple right angle triangle with a base of 1.5x10E11m and height of 1.5x10E7m at max and a simple line at min.

The position of the sun is posted at NASA's jpl/horizons web site for any instant in a a few thousand years. There the location is titled "apparent and astrometric" and both locations are in different places on the "Right Assention" and "declination". Can you say if these locations are the same pionts being kicked around on this thread as the gravity and light source of the sun? Or these locations yet another mystery having nothing to do with the true location of the sun?

Where would the FTL signal come from? Radar travels at lightspeed, and the gravity between planets is too weak to measure its speed directly.

I would suggest starting with study of the Fogal semiconductor, which device has been tested and independently verified to produce FTL signals.
