Modern general relativity states that the initial state of the Universe, at the beginning of the Big Bang, was a singularity.
Before this, as Stephen Hawking wrote, there was nothing: No space. No Time. Non-existence.
“Singularity” represents the very first moment of time, 10-43 seconds, when all matter, energy, space and time exploded outward from the original singularity.
Four concepts. Four instruments. Four interactions. Four conversations.
For our convenience, that infinitesimal moment of time has been slowed so that it now encompasses nearly eight minutes.
