Planck Time

10-35 s

End of GUT

10-35 to 10-33 s Inflation

Temperature Characteristics of the Universe infinitely small, infinitely dense infinite Primeval fireball 1 force in nature - Supergravity Earliest known time that can be described by 32 modern physics 10 K 2 forces in nature, gravity, GUT 3 forces in nature, gravity, strong nuclear, electroweak 1027 K Quarks and leptons form (along with their anti-particles) Size of the Universe drastically increased, by 1027 K factor of 1030to 1040 4 forces in nature, 1015 K protons and neutrons start forming from quarks proton, neutron production 1014 K in full swing

10-12 s

100 s (a few minutes)

Nucleosynthesis era

109 - 107 K

helium, deuterium, and a few other elements form

380,000 years

Recombination (Decoupling)

500 million yrs Galaxy formation

10 K

14 billion years Now or so


Matter and radiation seperate End of radiation domination, start of matter domination of the Universe galaxies and other large structures form in the universe You are reading this table, that's what's happening.
