Part 4/8:
To grasp the implications of the Big Bang, it is essential to rethink our understanding of time and space. In Einstein's model, time is not a universal constant but is relative and varies between observers. Rather than employing a linear timeline to trace the moments leading up to the Big Bang, we should utilize geodesics—paths in the fabric of space-time—as tools for exploration.
These geodesics depict how all points in the universe converge at the singularity, though this singularity lacks an inherent spatial characteristic. The notion of "before" the Big Bang becomes irrelevant; timelines effectively cease to exist at this point. Still, it raises a compelling question: if the geodesics converge at the singularity, what comes next?
