This animation depicts two versions of the three dimensional projections of six dimensional Calabi-Yau Manifolds morphing into each other. These types of Manifolds are utilized to incorporate String Theory into Cosmology. Universes with different values for the Cosmological Constant can be depicted as having different forms of the Calabi-You Manifolds. It is theorized that a universe’s Cosmological Constant could change when the manifold of that universe morphs into a different type via quantum tunneling. For further discussion check out
Chapter 6 (New Thinking about an Old Constant – The Landscape Multiverse) of the book The Hidden Reality (Parallel Universes and the Deep Laws of the Cosmos) by Brian Greene.
Here is my video of the morphing of two Calabi–Yau Manifolds:
