Who set the start of our Universe?

The inquiry into the origins of our Universe is a formidable challenge. Furthermore, the question of what existed prior to its inception is equally perplexing. Despite the magnitude of this inquiry, scientists have made significant strides in the 20th century. The pioneering work of Edwin Hubble, for instance, has shed light on this enigma. While observing the sky from Mount Wilson in Southern California, Hubble discovered that the seemingly random clouds of gas were, in fact, other galaxies. This revelation was groundbreaking, as it revealed that the Universe was expanding. This expansion, in turn, suggested that the Universe had a beginning. By tracing time backward, scientists were able to develop the Big Bang Theory, which provides a comprehensive explanation for the origins of our Universe.
