Caption

This false-coloor image of the large-scale structure in a computerized Universe reveals the process behind the new technique. On the left, a regular virtual universe has the locations of galaxies highlighted in blue, showing how they cluster together. In the early Universe (center) the relationship between these blue regions and the orange regions that expand into empty voids was symmetric. This allows a reverse version of the cosmos to be built (right) where the galaxies now inhabit the very regions that used to be empty voids. The latest results show how combining results from the original and reverse virtual Universe is a quick way to make accurate predictions for the real cosmos.
