New Galaxy Wall

<br />what would happen at the center. Wouldnt GR say that space time would bend in one direction or the other because of the the tightening of "lines of equal gravity" creating a cosmic low pressure system, similar to what we see on the evening weather report?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

Supposing that were true, where do we see anything like that in the distribution of galaxies? See the picture at the link at the start of this topic. The "lows" alternate with "highs" in circular rings around us. If we were some sort of center for a space weather system, wouldn't we expect spiral ring arcs either expanding away from us or closing in on us?-|Tom|-

I was thinking more along the lines (very simplified), if you have a series of stacked circles with points (random coordinance) being revolved around the circumference of each, would this not represent every possible non-verticle direction with one point in relation to the others. Now if you break each circle and connect them and all the points are moveing "down" while at the same time around, this would not contradict the observed phenomena or would it? You also must remember that the circumferance of the circle at the "top" is much larger that that on the bottom, which is what causes the acceleration and red shift. Am I making more sense now?

If I have your picture, that would still require that the galaxies follow a spiral path around the sky. But the path is a great circle, not a spiral. And there is no sign of the "layers" you speak of. Instead, the circles seem to be rather wall-like in the vertical direction. -|Tom|-

Could the red-shift not be considered evidence for the spiral, which is a great circle with verticle motion? As for the layers, that was merely for illustration. The wall of bodies in a great circle, with the doppler shift provides an even more beautiful picture of the cosmos. We must remember that our observations are not removed and objective, they are quite heliocentric due to de facto technological limitations. For this reason the doppler red shift would be the only evidence of the verticle motion.

Redshift at best measures motion only in the line of sight. And that is ignoring lots of recent evidence that the redshift is not doppler at all, but was caused mostly by energy loss instead. -|Tom|-

Rousejohnny, if we were at the center of some sort of "space weather pattern", like water going down a drain, and the galaxies were revolving around us, then we should be observing quite a bit of proper motion in these galaxy walls. We don't see that.
