Asymmetric laws of physics made matter win over anti-matter(1*). Annihilation💥 stopped when thermal energy fell 🌡️ to rest mass energy of proton ; temperature being 10^13 K. The universe has expanded by a factor of 100 from the quark soup 🍲 era(3*). 10^(-6) seconds after big bangHadron Epoch(2*):Quarks combined to form hadrons and anti-hadrons. Somehow one of the hadrons managed to survive till the first second when this epoch ended. Theory predicts, about 1 neutron remained for every 7 protons. This ratio of 1:7 is still observable strengthening the theory.About One second after big bang☄️Neutrino Decoupling and Cosmic Neutrino Background(CNB) : Neutrinos which were till now in thermal equilibrium with protons , neutrons and electrons ceased interaction with other types of matter and influencing the dynamics of early universe.The🌡️ temperature of universe was about 10 billion kelvin.Big Bang Cosmology also makes prediction about the neutrino environment called CNB. It says that about 1 sec after big bang the map of universe was imprinted with CNB. We haven’t been able to detect it till now due to its extreme low energy📉Primordial Black Holes :⚫Due to high densities and inhomogeneities during the first second , some regions would have become sense enough to undergo gravitational collapse and form black holes. Current theories have many unanswered questions to this event.First 10 seconds Lepton(2**) Epoch:Similar to the hadron epoch , the leptons dominated📈 the mass of universe now. About 10 seconds after big bang , the leptons and anti-leptons annihilated each other leaving high energy photons.Between 10 seconds and 370,000 years after the Big BangPhoton(2***) Epoch : Photons now , interacting with charged particles , continued dominating the universe for a long time. Between 2 minutes and 20 minutes after big bang Nucleosythesis of light elements :The temperature 🌡️ and pressure conditions are now right enough to allow nuclear fusion to occur giving rise to a few light elements beyond hydrogen.About 25% of the protons with all the neutrons fuse to form deuterium and most of the deuterium quickly fuses to form helium-4. Other unstable elements were also formed.The resulting matter is about 75% hydrogen nuclei, 25% helium nuclei, and 10−10 by mass of lithium-7. 47,000 years after Big Bang Now the universe is matter dominated. The densities of ordinary matter and photons becomes equal to Jeans length – the length at which the structure formation by dominance of gravity can take place.1 million years after Big BangNow the universe has sufficiently cooled down to form the first molecule – helium hydride. Much later on the timeline , atomic hydrogen and helium hydride reacted to form molecular hydrogen necessary for star⭐formation . The universe till now was opaque. If you could somehow travel back to that time, you will see nothing . The universe was blind ! So, how we got from 0 visibility to pointing Hubble telescope in space ?What do you think about this? Any ideas? let me know your guesses in the comments below.We have now come too far , from the first microsecond to 1 million years. More interesting events , are yet to come. To all those who are reading this till last , just take some time to appreciate the complex existence of our life structures.(1*)- To know how matter won over anti-matter , check out my blogpost -(2*) (2**) (2***)- Hadrons,leptons,photons are a part of particle physics.
