What I indicated was the time radius. If you look at my diagram in
http://www.dualspace.net you'll see that the maximum distance could be
pi times that radius, being real space along the arc which subtends a
time axis radius m/l of 10-13BLYR.

I understand the basis of your calculation. I was taking exception to
using this figure as the size of the Universe. "Generally" the Universe
is taken to be many orders of magnitude larger than this.

I also take exception to your suggestion that it is "widely surmised"
that a "new physics" is required to explain the Pioneer 10 anomaly.
There are perfectly good explanations based on conventional physics.
These include mundane possibilities related to thruster leakage or
asymmetric heat radiation, and more interesting ones involving dark
matter. At this point, there is no particular reason to favor a
modification of gravitational theory over the simpler explanations.

It's easy to say "There are perfectly good explanations based on
conventional physics" but the fact is the "mundanes" have been
investigated and discarded. Pioneer 10 was fortuitously special, being
spin stabilized and without thrusters. That would be essential
because even at 20AU, A_p is 16,000 times lower than Sun's gravity.
70 watts were produced by plutonium heat sources on the ends of long
booms and would have needed to point in the same direction..

An article I printed from the web (link is no longer good) quotes
such people as Wilczek, Weinburg, Anderson, Haisch discussing the
problem with every indication that the "usual suspects" have been
exonerated.

I have a new gravity theory which adds a term to Newtons equation and
delivers all of GR and SR results. It results from a 3d universe
flying through time at c (hence the R = cT), rather than relativity's
4 dimensions all soldered together. And c varies with gravity rathwer
than time dilation. There's a sampling at my website
http://www.dualspace.net, where I dissect various gravitational
effects like the GPS corrections. Naturally the derivation up to that
point is not included, as it is difficult to have anyone look at even
two equations.

If you have something to say write an equation.
If you have nothing to say, write an essay.
