It's nice to know, when I start my car, that god, for some inscrutable reason, has decided once again to allow petrol to burn at precisely the correct temperature and rate to power the engine. :tea:

My poor thread has been hijacked into a rambling discourse about gods, with attempts at humour! :lay:

I've got a physics question - not a problem as such.

How do 'we' (by which I mean 'others') work out how old a galaxy is? I know its distance from us has something to do with light but, like, how do 'we' distinguish between relatively near and old galaxies and relatively distant younger galaxies. And is that even a sensible question?

From what I've read, it has to do with the average age of the stars within the galaxy themselves. If a high proportion have passed through the various stages, and so are white dwarfs, for example, that galaxy would be older than one containing a high proportion of young, blue stars.

Firstly, a gentleman should never ask the age of a galaxy in the first place! But, that aside, it is simply a matter of cutting open a few stars and counting the rings. You're welcome. :tiphat:

I think counting the rings is a more poetically satisfying answer. :D
