A number of years before the Internet was born, I read an article in which the author claimed that, at the site where the Big Bang happened, a "naked singularity" should exist. Like the Big Bang itself, which brought the Observed Physical Universe into existence, a naked singularity should also be able to violate the Energy Conservation Law, and continuously spew stuff. The implication is that the Big Bang might still be happening! It's just happening farther away than we can see. Let me see if I can explain my understanding of the situation (should there happen to be something "to" it). Cosmologists describe the expanding Universe in terms of a balloon, something we all are familiar with. But their simplification of the situation is "off" a Dimension. After all, any small portion of the surface of a balloon resembles a mostly-flat 2-Dimensional area, and our Universe is obviously 3-Dimensonal, at least. Mathematicians know that the circle (a 2-D thing) and the sphere (3-D) have a 4-Dimensional equivalent, which they call a "hypersphere". Any portion of the surface of a hypersphere is a 3-Dimensional volume, equivalent to what I described above about a portion of the surface of an ordinary sphere. As we stand on the surface of the basically spherical Earth, we see that there is a limit to our ability to view its surface, known as "the horizon". Similarly, the Observable Universe has a kind of "horizon", too, usually known as the "red shift limit". It is not impossible that our entire 3-D Observable Universe is just a tiny portion of the overall surface of a huge huge 4-D hypersphere. I'm aware that cosmologists have been looking for evidence that Space has some "curvature", which would be strong evidence in favor of a hyperspherical Universe, and that so far, Space appears to be entirely "flat". Well, we know how long it took humanity to find evidence that the surface of the quite-larger-than-us Planet Earth was curved instead of flat. The verdict is still "out", awaiting more evidence. Imagine we could teleport instantly from the Earth to a distant place, say 13 billion light-years away. We could look back toward the Earth and see our Milky Way Galaxy to be very strongly red-shifted, and possibly spewing a powerful jet from its nucleus, like a quasar (because we would be seeing it as it existed 13 billion years ago). But suppose we turned around and looked farther away in the direction we had just teleported? What would we see? Even more galaxies, occupying an additional segment of the surface of that huge huge 4-D hypersphere? To be determined! Anyway, I've gotten distracted from the Big Banger. It's location, whether still spewing or not, would obviously be at the center of that 4-D hypersphere, and we have no way of "looking" in that direction! Stuck in the 3-D surface we are, unable to access the Dimension of "hypervolume". However, just like we imagine Planet Earth to consist of various layers, like "crust", "mantle", and "outer core", we can imagine that 4-D hypersphere to be layered, too, like an onion. Each layer could be a vast 3-D volume, such that any small portion of it could be equivalent to our Observable Universe. We might not actually be occupying the outermost layer! Now the reason for writing this message is actually to ask a Question. I just had to present the background information before I could ask it. So, IF the Big Banger is still Banging away, it logically follows that the overall mass of that 4-D hypersphere has been growing for a long long time. Might it eventually become massive enough to stop the accelerating expansion of the Observable Universe, and eventually lead to a Big Crunch??? Thanks in advance!
