Hi Jorrie,
Thanks for responding. According to the SPM, recession would begin at a distance equal to the radius of a sphere that had a density equal to the critical density with the object at its center. Is this not a currently accepted premise based on LCDM?
Thank you for your prompt reply. I do understand the idea behind using supernovae type 1a as a standard candle to calculate distance and red shift to calculate the recession rate. What I am trying to ask is, If you have an object, galaxy or galaxy cluster, of known mass how does one calculate...
