About This Video

Physics tells us that the amount of information that can be placed within a Planck area—the smallest, indivisible unit of space—is finite and immutable. Thus one can map out the atoms in a room as a three-dimensional grid of Planck lengths—forming what are called voxels. But what physicists such as Leonard Susskind wrestled with is that this is too much information to possibly work, leading them to to suggest the possibility that reality is only mapped on to two dimensions.
