Q2: If the universe were contracting, ANY galaxy in the "blue shell" in your model would be approaching us. Also, ALL galaxies on the "other side of center" would also be approaching us, though you could make the argument that they are too far away for us to see. Q1: With respect to the "starting point" of the big bang, no, you can't find that. Go to the bread analogy, you can only find the center by measuring the speed of raisins with respect to the baking pan, where the baking pan represents a stationary reference. If you are standing on a raisin, (any raisin), your view is the same, all the raisins are moving away from you, at a speed proportional to distance from you. Regarding the Pioneer Anomaly, common understanding is wrong. A clock receeding from us does not actually run slow (compared to our clock), it only APPEARS (to us) to run slow. A clock approaching us APPEARS (to us) to run fast. It is simply Doppler shift. Look up "binary pulsars". On the other hand, if all galaxies are moving away from all other galaxies, how is it that galaxies collide? (And they do, there are a number of spectacular photos of such events.)

Here is a thought... If the universe really is expanding , is there a huge ever-increasing "hole" in the center, presumably at the site of the Big Bang?

There are some interesting writings about the Pioneer 10 and Pioneer 11 anomalous acceleration. Google it or refer to http://www.space-time.info/pioneer/PioneerAnomaly.html for details
