Abstract
We review here the recent success in modeling our expanding universe according to the rules of flat space cosmology. Given only a few basic and reasonable assumptions and a single observational input, our model derives a variety of results which correlate with astronomical observations, including best estimates of the size, total mass, temperature, age and expansion rate of our observable universe. Considering the apparent success of our model, we attempt to explain why we think it works so well, including the fact that it incorporates elements of both general relativity and quantum mechanics. We offer this approach as a possible avenue towards understanding cosmology at the quantum level (“quantum gravity”).
Highlights
Flat space cosmology is our newly introduced heuristic model of cosmology [1] [2]
Relying on only a few basic and reasonable assumptions, it has allowed us to derive a variety of numbers in close agreement with astronomical observations, including 2015 Planck survey results [3]
Given the apparent simplicity of our mathematical model, we have been pleasantly surprised by the excellent correlation between derivations from our model formulae and astronomical observations
Summary
Flat space cosmology is our newly introduced heuristic model of cosmology [1] [2]. In our introductory paper [1], we derived Hubble parameter H0, Hubble radius R0, Hubble time HT and total mass M0 values for our current observable universe relying only on our basic assumptions and current CMB radiation temperature T0 = 2.725 K. (2015) Flat Space Cosmology as a Mathematical Model of Quantum Gravity or Quantum Cosmology. We summarize the key mathematical relationships and attempt to explain why such a simple model works so well
