how is universe form? answer in 200 to 300 words

Answer 1

The Universe is formed when there is explosion in very infinitesimally small particle called big bang.
And after that quarks are formed and after that our first element hydrogen

Answer 2

The prevailing model for the evolution of the Universe is the Big Bang theory. The Big Bang model states that the earliest state of the Universe was an extremely hot and dense one, and that the Universe subsequently expanded and cooled. The model is based on general relativityand on simplifying assumptions such as homogeneity and isotropyof space. A version of the model with a cosmological constant(Lambda) and cold dark matter, known as the Lambda-CDM model, is the simplest model that provides a reasonably good account of various observations about the Universe. The Big Bang model accounts for observations such as the correlation of distance and redshift of galaxies, the ratio of the number of hydrogen to helium atoms, and the microwave radiation background.
