The concept of traveling back in time before time existed is paradoxical and falls into the realm of philosophical speculation rather than scientific understanding.
Time, as we understand it, is intricately connected to the fabric of the universe and its physical properties. It is thought to have emerged with the Big Bang, the event that marked the beginning of our observable universe. Therefore, speaking of a time before time existed raises logical difficulties.
When discussing time travel, it is generally assumed that time already exists, and the question revolves around manipulating or traversing it in various ways. The possibility of traveling before the existence of time as we know it is beyond the scope of current scientific understanding.
However, it's worth noting that some speculative cosmological models propose the idea of a multiverse or a cyclical universe, where time and the universe itself may have existed in some form prior to the Big Bang. These concepts are still highly theoretical and lack empirical confirmation.
Ultimately, the question of traveling before the existence of time is a topic that lies outside the boundaries of our current scientific understanding and remains a subject of philosophical and speculative inquiry.
