Based upon a few number of reasonable initial assumptions, our cosmological model universe is always flat and yet it shows a remarkably robust inflationary expansion effect within a tiny fraction of the first second of universal time. Our thermodynamic formula closely resembles Hawking's black hole temperature formula, and yet it appears to correlate closely with cosmic temperature vs. time derivations from experiments in particle physics. Lastly, our model supports recent credible challenges to the current concept of dark energy. http://pubs.sciepub.com/faac/1/2/3/faac-1-2-3.pdf flat space cosmology LCDM cosmology cosmic inflation dark energy hubble parameter hubble radius CMBR redshift schwarzschild formula hawking black hole temperature formula friedmann critical density
