The smallest unit is the Planck Length. Theoretically, it is not that there can be nothing smaller, but for various reasons that have nothing to do with the limits of technology there is nothing that can be known about anything that happens to be smaller. For scale, the number of Planck Lengths in the diameter of a proton is 10 to the twentieth power.
