Current scientific understanding suggests that light, as we know it, did not exist before the Big Bang. The Big Bang theory posits that the universe began from an extremely hot and dense state, leading to the creation of all matter and energy. Light, in the form of electromagnetic radiation, emerged as the universe expanded and cooled. Prior to the Big Bang, conventional concepts of time and space may not apply, making it a challenging subject for current physics to describe.
