Re: Origins of Globular Clusters
Thanks. I think that is the information I was looking for.Earlier in the evolution of the universe there were probably more numerous large concentrations of dense gas that became Globular Clusters.

Origins of Globular Clusters
I have two questions about Globular Clusters: 1) How (under what conditions) did GCs from? Did they start out as very compact objects or did they begin as more extended groups of stars that then coalesced? 2) Are GCs still forming in our galaxy or in any other galaxies at present? If not, were they ...

Re: Redshift and energy conservation
Are any or all of these statements true: 1) The first law of thermodynamics isn't really a law. (I know it doesn't apply at very small scales where virutal particles can appear/disappear but this is a macroscopic, long lasting system. Is the first law just a Newtonian approximation?) 2) The answer t...

Re: Redshift and energy conservation
I did read this thread before posting and from the fact that my question got moved here I gather the answer may be here somewhere but if so I don't see/understand the answer.
Any insight into this? Are you implying that there is a GR solution?

Conservation of energy and expansion
Suppose there are two rocks, galaxies, whatever. They are a certain distance apart, and falling towards each other. This system has a potential and a kinetic energy and the total energy of the system remains constant. Now suppose I reach in and drag the two farther apart. There is now more potential...
