Colliding Branes and the Cyclic Universe (version 1)
Animation showing the regularly repeating collisions
of our three-dimensional world (referred to as a
"brane" or "braneworld" in string theory) with
another braneworld along an extra dimension and the
various stages in the evolution of the cyclic universe.
Colliding Branes and the Cyclic Universe (version 2)
Similar to version 1 but colorfully emphasizing how
the wrinkles caused by quantum fluctuations create
temperature variations after the bang like those
observed by cosmologists in the cosmic background
