I think the idea is that energy bubbles like the one our universe was "Created from" CAN just manifest, we're not talking like a building just appearing in the middle of your living room, on the particle level because of an inbalance in matter.You see because we have a lifespan as living creatures I think we just apply time to everything as a matter of quantifying it i.e If its happening now it has to have started at some time and it will end at some point in the future, but I don't think this really applys to the universe because it's a continuing cycle when you argue about its orignal creation, if God made the earth what made god, and who made them, and who made them forever and ever.So I don't think there ever was a start of the universe or will ever be an end. They say that when a stars life ends it turns supernova but if you look at it on a molecular level it hasn't really ended because whatever you can class as matter from it still exists in another form in space.yh bare guys trying to pinpoint the start of infinity on road,sh*t is looped up still,outside of our dimension of comprehension tbh
