I would like to open this question up and see what the responses are. There is new evidence that is coming to light that our universe is not flat but it is curved. This has sparked ideas that the Big Bang theory is false and that our universe is really a black hole. If the universe is and continues to expand than the flat plane that we associate and conceptually understand our universe to be, forces it to curve in upon itself. It must be due to the vacuum of “A” black hole but not saying our universe is the black hole. What are your thoughts on the topic? Hoping to shed light on the topic, which could be another topic for the future? Eg: Outside light traveling at different speeds with shape of the universe folding and expanding.

Michael,
The Big Bang theory says little about the geometry of space a Long Time after the initial expansion. Thanks to Dark Energy (aka, something we don't understand except that it's a neat name for a poorly understood pressure), it appears that the Universe may well have a negatively curvature - ie, it never recollapses and nor is it flat.
When I was a lad there was a fervent hope that the average mass-energy density would be found to be sufficient to close the Universe, alas that conceptually neat solution appears not to be the case.
Hey ho.
Thse shape of the Universe has been accurately measured to within 1 percent. Recent spectroscopic measurements at the Apache Point telescope in New Mexico were used to make ultra-precise spectrascopic measurments, and the findings are that not only is the Universe "flat" in geometric terms, but almost certainly endless as well. I have suspected infinite for a very long time, as pointed out in my comments on the topic "Does God Exist?" http://www.space.com/24207-dark-energy-galaxy-map-aas223.html
The actual universe is curved, in fact hyperbolic.

If you believe big bang you must consider a singularity. I think the universe has not been created and will not be collapsed. It is the matter of dimension. Our universe can not be seen at one of the possible parallel universe in another dimension. All the concepts are theories and has not been proved completely. You can not find a permanent phenomena in universe. All the rules are the function of time. Space is meaningless. We are traped in our dimension. Black holes are not so black as Stephen Hawking proved. If we know our universe completely, we would only know about one of the billions possible universes...
