Original text: Sabine's flatfield versus rotators angle look promising, but more tests should be done which do not depend on the structure looking like a finger. ... The halves could be either ordered by rot-angle (e.g. 0-180 together, 180-360 together), or totally random. ...

As the Universe expands, gravity pulls on the Universe, and slows the expansion down over time. As we look to great distances, we are looking back in time. If we can measure how fast the Universe is expanding in the past, and compare it to how fast it is expanding now, we can see the total gravitational effect of all matter in the Universe. Here we plot the distance between two galaxies as a function of time. ... Universes with lots of material . ...
