Quand a eu lieu le big bang ?<end_of_turn>
<start_of_turn>model
It took place about 14 billion years ago, almost three times the age of our Solar System and of planet Earth in particular. Until a century ago, astronomers thought that the Universe was immutable and eternal, that it had always existed. Today, the theory that there was a beginning – the “big bang” – and that it is constantly evolving is supported by a body of observations.<end_of_turn><eos>
