Our quantum theories may need work. Quantum theories of Physics insist that space is quantized just like everything else, that is to say space can not be continuous but must be grainy and the lumps in space must be as large or larger than the Planck Length of 1.62*10^-35 of a meter because size is meaningless in quantum theories if things are smaller than that. But now to everybody's surprise there is experimental evidence that seems to say that if space is quantized at all then the lumps must be smaller than 10^-48 of a meter; that's at least ten thousand billion times smaller than the Planck Length, the smallest size previously thought to exist and it makes one wonder if the smallest possible size is actually zero.
