I personally haven't committed to any particular theory myself, however based on the evidence i am confident that the Universe (the Spacetime which we are apart of) has a finite beginning.
... There are three factors to consider when discussing the nature of the Universe, the first is that all the energy(mass) which exists in the Universe today existed in the beginning, the second is that the Universe is expanding and the final one is entropy in that the Universe has a direction. I suspect the conditions or state which gave rise to our Universe were also intrinsically consequential to the very laws which govern it, in other words the way in which our Universe came into existence also determined the nature of it.
When I say "I like", it does not mean I have "committed" to anything. A fan of science must be akin to a hormone-driven young person, already ready to shift their attention to the next great discovery, and brutally ditch the last if need be.
I like the "large universe" idea due to observations that space is completely flat, which suggests that the actual universe may be exponentially larger than the observable universe.
Still, maybe all of the energy in the universe today is not the same as that at the beginning? If the BB was, as most think likely, an event occurring on a pre-existing reality (as opposed to bursting forth from absolute nothingness) then its energy quotient may only be a small subset of the total energy in existence.
The unidirectional nature of the universe's expansion, entropy and time has a number of physicists suspecting dark energy of being the source of these phenomena. Of course, this does nothing to explain the nature and origin of an eternal, universe-making and breaking outward driving force, which is utterly weird.
When you think about what dark energy is proposed to be at this early stage, it's not wildly different to notions of God, being eternal, omnipresent, all-powerful, mysterious, unknowable and it makes and breaks entire universes.
