FRW Derivation History: Acker's Questions Answered

[Acker]

Hello All,

I wondered if anyone could fill in some details about the timeframe of FRW derivation.
Was it derived to purposefully address the expansion of a universe? and if so, how did
anyone know about this prior to Hubble's observations?
Or was it derived for some other purpose and then applied after Hubble?
I am keenly interested in this and would love to hear any information in this forum
regarding the reasons for deriving this cosmological equation.

Regards
Acker

edit. And was it derived using Newton before Einstein's gr or between gr and Hubble's observations?

Are you not familiar with Wikipedia?

Thank you Phinds, for your thoughts on the matter.

When I am asked something, I tend to refrain from handing someone an encyclopedia
and quipping 'go look it up'.

It is such a relief that we can always turn to wikipedia for definitive discourse.


Best regards
Acker

Folks who come here with questions are expected to have made at least some minimal attempt to do their own homework first, and it sounded as though had not done so.
