Let's define the universe as the totality of that which is contained within spacetime.

That works fine as long as you qualify the term Universe by saying that you are speaking of the Physical Universe; what about the stuff that exists having no mass, is not readily apparent, is not measurable as to location and momentum in Space-Time; the single substance from which the Heavens and the Earth, the Physical Universe, the Reality of Everything is made of.
Existence, Reality, is there a time when something might not exist and then begin to exist, "something that has no cause, is to be defined as being the "beginning; the first in a series, the beginning of a process such as the Evolutionary Process, the beginning of a continuum such as Space-Time.
The problem with understanding the beginning is that, "in the beginning" the only thing that existed was Nothingness.
If you include nothingness in the definition of Universe then in the beginning of the Universe was without form, void, there being only Darkness upon the deep.
When was the Light separated from the Darkness??

Into the Light, differentiated Time began at the Zero-Hour, at the Event Horizon, at the Moment the Light was separated from the Darkness, the Day from the Night.
