In the early 20th century, cosmological physics was returned to the edge of time, and the question: what ‘came before' the Big Bang? For cosmology no less than for transcendental philosophy - or even speculative theology - this ‘before' could not be precedence (in time), but only (non-spatial) outsideness, beyond singularity. It indicated a timeless non-place cryptically adjacent to time, and even inherent to it. The carefully demystified time of natural science, calculable, measurable, and continuous, now pointed beyond itself, re-activated at the edges.
