Dense packing of stars
On another point I just wonder if these globular clusters are not failed galaxies. The original dust cloud was not dense enough to enable the super massive stars at or near the center to spin up the accretion disk which means that a black hole was not formed as there was not sufficient gravity. I gu...

Hickson 44 (APOD 19 Mar 2007)
When I look at these groupings a couple of wonder if's come into my mind. In a simplistic version of the big band I would expect the size of the cluster to be in some propotion to the red shift. Does anyone know if there has been any red shift work done on this grouping to see if this holds true. Al...

Battered Earth
Wolf If the moon is captured or a piece of the earth would not in my opinion matter. Tidal locking no matter when it occurred appears to be the cause of the difference in crater density. To say that the maria only occurs on one side of the moon or is related to debris collision in a particular patte...

Battered moon
"In a nutshell, because we don't know if the simple response is the correct one. In fact, I believe there has been some work showing the idea of an impact "shadow" is insufficient to explain the discrepancy." I have found through a long time working in Geophysics that if the obvi...

Battered moon
Accepting that the moon was not always tidal locked, the side facing the earth has still had less impact than the side facing away since it became tidal locked. The obvious explanation remains the same.

Battered moon
Exactly added to the fact that the moon is ina tidal lock and so the near side is protected by the earth. Why do we have to go to more complicated explanations, thicker mantel for example, when there is a simple response is more obvious.
