History of Bravinia

Like everything even the history of Bravinia, began with the big bang. Before the big bang there was a massively dense infinitely tiny singularity a point of which time and the laws of physics didn't exist. Then the singularity "exploded" to make the big bang, immediately after the big bang about 13.7 billion years ago the four laws of universe were created (time, space, matter, energy). The first era after the big bang was called the radiation era itself divided into differnet epochs (planck - immediate, grand unified - 10⁻⁴³ seconds, inflationary - 10⁻³⁶ seconds, electroweak - 10⁻³² seconds, quark - 10⁻¹², hadron - 10⁻⁶, lepton - 1 second, nuclear - 100 seconds). After the Radiation era the next era after 50 000 years since the big bang took place - the matter era which was also divied into different epochs (atomic - 50 000 years, galactic - 200 million years, stellar(still the current epoch) - 3 billion years).
