Development Of Universe After Big Bang



Visual representation of the development of the universe.: After the Big Bang it expanded very quickly, till stars, galaxies, and finally our solar system were found

How did space originate?

The starting point of the universe was a tiny, very compact core, with an unimaginably high temperatures. About 14 billion years ago, this core exploded in the event called Big Bang, Space and time were created only after this, so one cannot say what was present before the Big Bang. After the Big Bang, the space expanded within a few seconds. This is known as 'cosmic inflation'. Electromagnetic radiation arose, and after 15 minutes there were the first atomic nuclei. About 3,00,000 years later, atoms were formed and the universe had cooled down to a temperature of 3000°C. After around 500 million years the first stars originated.
