Part 4/10:
According to general relativity, space and time are interwoven within a single continuum. If the Big Bang marks the inception of space, it simultaneously signifies the commencement of time. Therefore, inquiring about what occurred before the Big Bang closely resembles asking, "What lies north of the North Pole?" The complexities of such existential inquiries often make them seem absurd due to the inherent limitations of our scientific frameworks.
Nevertheless, physicists remain undeterred, presenting various speculative theories concerning the pre-Big Bang existence, albeit recognizing that these ideas reside within the realm of ongoing research rather than established scientific facts.
