A new equation developed by a physicist at Imperial College London suggests that the universe may have had no beginning, challenging the widely accepted Big Bang theory.

The equation, which is based on quantum gravity, proposes that the universe is constantly fluctuating between states of expansion and contraction and that there was no initial singularity or starting point of time and space. This is contrary to the prevailing view that the universe began from a hot, dense state that rapidly expanded creating what we observe today.
