It's Official: We Were WRONG About the Big Bang

It doesn't need to be expanding "into" anything at the very least not from our perspective. If it is let's say a bubble among many, from our viewpoint the "space" they inhabit may be completely irrelevant to our science here as, being outside the boundaries of our universe, every physical law can be completely different. This might mean that we don't ever need to take it into account for any calculation ever within our universe. Taking it further you're asking what is the fabric of our space expanding into but this is funny no? I mean the analogy is the bread expanding into our space but our space can be stretched and expanded. What's to say the "space" where the universes lay, doesn't have this function? Or that it is what is actually expanding and causing ours to expand by proxy? 
Then there's the whole infinite thing. Not necessarily, this presupposes some kind of all encompassing homogeneity existing throughout this reality and the reality that holds this reality, which doesn't seem correct. Our universe with our current laws may have started with a big bang, be expanding into another "super" reality, and the "super" reality could be infinite while ours is finite. There's also the possibility that trajectory lines or space work different in the super reality than it does in the "sub" reality. Our universe existing in that reality would then mean the formation of it could follow the laws of that reality while we inside it can only perceive based on the laws inside. Imagine string itself is your universe right? Well here in the "super" reality the string can be folded bunched up balled up or stretched out perfectly and it wouldn't make a difference to you living within the string universe. Now lets say theres a glass bottle and the bottle has inside of it, its own physical laws, I start putting string in the bottle slowly feeding it into the bottle, as the string goes in, it creates the string "sub" reality. Now the beings in the string sub reality they experience the bottle but don't know they do because it is constant unchanging background not just that but the perception of the bottle requires the physical laws of this reality, which the inside of the bottle does not have. To them, the real universe is the string itself. Now i can keep feeding string into the bottle and first it might be straight before it touches the borders of the bottle but eventually it touches the border and begins bending folding bunching up. To us it's bent and bunched up, to them, it isn't, because their entire reality exists within the string itself once the string is within the border of the physical laws that the bottle has inside. They would notice their universe expand and wonder what it's expanding into, and relative to them, that could be nothing. The string can be bunched up more and have more string within the same volume from our super reality perspective, but they would just see their universe expanding as more string is put into the bottle, even if its bunching up and compressing itself from our perspective. This could be how our universe expands. Imagine what to us is intangible space to a being in a super reality above ours is let's say a physical item that can be infinitely bunched up and folded in on itself. We would not have the ability to perceive that, living within this reality and subject to its physical laws.

Oh, there you go, right at the end touched on just about all of this. Might still help someone conceptualize it better though so I'm commenting it anyway.
