Critical points with time running forward
		• 10-45 sec       Quantum gravity?  Physics not understood • 10-34 sec   1026 K     Nuclear strong force/electro weak force separate          (inflation, matter/antimatter asymmetry) •   10-7 sec   1014 K     Protons, Antiprotonsphotons •   10-4 sec   1012 K     Number of protons frozen •     4   sec            1010 K                     Number of electrons frozen •     2   min        Deuterium nuclei begins to survive •     3   min   109  K     Helium nuclei begin to survive •   30   min           108  K                        T,  too low for more nuclear reactions          (frozen number of D, He -- critical prediction) • 300,000 yr   104  K     Neutral H atoms begin to survive          (frozen number of photons – critical prediction) •  1 billion yr       Galaxies begin to form • 13 billion yr       Present time
