Gripped,I watched on -through an increasingly complex discussion of cosmic strings, space- time continuums and loops in the universe -all entertainingly presented,all explained in simple terms,but all utterly impenetrable.
This could be an optical illusion--or perhaps the result of some physical phenomenon such as spherical shock waves colliding or cosmic strings.

Our results point to several experimental and theoretical situations where such structures may be relevant, ranging from defects in liquid crystals and vortices in superfluid helium to the structure-forming role of cosmic strings in the early universe," Niemi and Faddeev say.
