Re: APOD: Anemic Spiral NGC 4921 from Hubble (2013 Nov 25)
What's causing the inward movement of so much dust? Gravity, or something else? Is it moving inward? I have seen projections that show some galaxies spiraling outward. Swirling 'Anemic' Spiral NGC 4921 certainly looks to be going down the drain and reminds me of the old W.C*. * http://en.wikipedia....

This is beautiful Hubble image. I see a cosmic firework unparallelled by any terrestrial burst.

Re: APOD: Globular Cluster M15 from Hubble (2013 Nov 19)
Doh! Some one beat me too it already. I should have read everything first. It is surprising it is so clear with few clouds. Is there a relativistic effect where objects that are accelerating can appear to move faster than light when moving perpendicular to the radial vector? :?: Is there something ...

Re: APOD: Globular Cluster M15 from Hubble (2013 Nov 19)
Well...Think of it as having the weight of the universe on your shoulders. Replace the notion of gravitational attraction with a universal tropism that likes to push things around. Things move from an area of high "gravitational" density towards areas of lower density. This density is grea...

One day everyone will know that "gravity" only appears to be an attractive force.
