The Hourglass Model
The idea first came to me when I read about the Randall-Sudrum model, a setup of two branes of which one is our universe (M-brane) and the other a gravity universe (G-brane). Even though our world, M-brane, is “supposed” to be an open, expanding universe with negative curvature of space because we can visibly count and see that there is not enough ordinary matter (stars, intergalactic gas, etc.) in this universe, it turned out that the WMAP and Planck spacecraft did measure the curvature to be nearly flat!
On the other hand, I noticed that if graviton is so densely concentrated in G-brane, its geometry should be different from that of M-brane. It should be a closed, contracting universe with positive curvature of space. So my hypothesis is that the curvatures of the two branes must have cancelled out each other and make our universe “look” flat. The appearance of this cancelling is dark matter and dark energy, which are energy oozing out from G-brane to M-brane.
Based on that, I suspect that our universe is cyclic: ever-increasing formation of dimension-tearing black holes which accelerate energy oozing will lead to an eventual collapse of the whole universe into a “5-dimensional soup,” which is so unstable that it immediately restructures back into the two-brane setup. if an observer can observe this Big Bounce event when the contracting G-brane and expanding M-brane bursting into two new branes, it would look like their contents have just swapped places.
Therefore, I call this model the Hourglass. It can provide explanation for the existence of dark energy, dark matter, and faster-than-light communication in quantum entanglement.
