Most likely reason? Our universe originated from a white hole we refer to as the big bang.

No, the big bang is not a white hole. A white hole has an antihorizon. Our universe does not.

  Can this really be said with any certainty? If we originated from a white hole, the effects on time would be difficult to measure from inside it, wouldn't it? Do you have some proven modeling of the inside of a singularity? If so, I would be very interested in that. I haven't been to the "edge" of our expanding universe, so I can't say anything for certain. I haven't been inside the event horizon of a black hole (or have we?), so I can't claim to say what happens on the other side of it. What I do know is it'd be pretty sweet if black holes are entry ways into new universes and our universe is the exit point of some other universe and we are currently existing in an exit point among a massive chain / fabric of countless realities, all of which we are connected to. So until we build chips that can reach the edge of our universe or ships that can travel to the origin of the big bang, or come up with irrefutable and provable models of what's really happening, I'm going to go with the sweetest possibility I can imagine.

Our universe is. > irrefutable and provable models of what's really happening Science can never meet this requirement, because we can never collect all possible data. But that doesn't mean we can't rule out some models. We can rule out a white hole model of our universe, for the reason I gave above.

      No, you really can’t claim definitive knowledge about singularities based on our current models. The rules—as understood through general relativity and quantum mechanics—change drastically at the scale of a singularity. No amount of observing shadows of a singularity conforming to predictions changes the ignorance regarding the interior of the singularity. Given that these conditions are fundamentally outside of our current observational capabilities and that existing theories are known to break down under such extreme conditions, it is presumptuous to apply conventional physical models developed for ‘normal’ spacetime. Until we have a unified theory of quantum gravity that is experimentally validated, any claims about the behavior within singularities remain speculative and should be treated with appropriate skepticism. Just because it appears from our reference frame that a black hole compresses to a point and a white hole emits from a point, does not mean that is the physical effect occurring from within the singularity. When dealing with infinite, the rules change. For all we know, beyond the event horizon, the environment could be as fantastical as a land made of ice cream and lollipops—where everything around is sweet and edible. Doubt that? Send a probe into the nearest black hole and somehow retrieve it. Also, locate and observe a white hole, and develop an engine with infinite thrust that can approach it. I'm sure there will be enough observational data then to make finite claims. Good luck!
