A big bang theory is a type of explosion that happened in space. This explosion can demolish planet.

This universal expansion was predicted from general relativity by Alexander Friedmann in 1922 andGeorges Lemaître in 1927, well before Hubble made his 1929 analysis and observations, and it remains the cornerstone of the Big Bang theory as developed by Friedmann, Lemaître, Robertson, and Walker.
