We don't know !


Space-time came into being after the Big Bang,

This was triggered by a perturbation in the quantum foam, which led to an unraveling of symmetries, giving the Universe the shape and character it now has.

Before the Big Bang space-time was a singularity, and the critical point was the Planck Time, #10^-43# seconds,

A singularity is an abstract concept and represents an indeterminate state of the Universe.
