BIG BANG TIMELINE FILL IN YOUR MISSING DATA

THE BIG BANG 0 to seconds Temperature- theorized to be infinite Infinitely small, Infinitely Dense, Primeval Fireball Only 1 force exists- Supergravity

PLANCK TIME seconds Temperature Kelvin Earliest known time that can be described by Modern physics 2 forces- Gravity, and Grand Unified Theory GUT

END OF GUT seconds Temperature Kelvin 3 forces exist- Gravity, Strong Nuclear Force, Weak Force Quarks and Leptons form (along with their anti- particles)

INFLATION to seconds Temperature Kelvin Universe increases in size by a factor of to 10 40

END OF UNIFIED FORCES seconds Temperature Kelvin 4 forces found in nature- Strong, Weak, Electromagnetic, and Gravity Protons and Neutrons begin to form from quarks

HEAVY PARTICLES seconds Temperature Kelvin Protons and Neutrons forming at full speed

LIGHT PARTICLES seconds Temperature Kelvin Electrons and their opposite particles (positrons) form

NUCLEOSYNTHESIS 100 seconds Temperature Kelvin Helium, Deuterium, and a few other elements form

RECOMBINATION/DECOUPLING 380,000 years Temperature Kelvin Matter and Radiation separate Radiation domination ends and matter takes over the Universe

GALAXY FORMATION million years Temperature- 10 Kelvin Galaxies and other large structures form in the Universe

NOW Approximately 13.7 billion years later Temperature- 3 Kelvin We sit here and take these notes today…
