Reload page to restart movie.
This movie is from the web site "Simulations of Lorentzian 2d Quantum Gravity" by Jan Ambjørn, K. N. Anagnostopoulos and R. Loll, http://www.nbi.dk/~konstant/homepage/lqg2/. The depicted spacetimes have one spatial dimension and one temporal dimension. Each edge in an image corresponds to a Planck length. Different colors indicate different spin states. Each spacetime forms a closed cylinder, where the top and bottom of each image correspond to the same points and should be imagined to be joined.
I am the author of the images and text except where otherwise indicated. Please contact me for permission if you wish to use any of my images or text.
