Heres a graph of the transmission spectrum of polycarbonate in light UV and IR. A pretty boring and straight forward graph but it got me thinking; what if we extended the left side of the graph to 0? Just one more tick on the graph? Not really, if we imagine that light is in the middle of the spectrum, since it is as far as energy and wavelength go, between the 200nm and 0 there exists the other half of the spectrum; UV, xray, gamma rays, the super high energy gammas science can detect but not explain, all the way up to the energies of strings of string theory, then the energy of the singularity of the big bang. Strings would live at energies with a wave length around a few plank lengths, almost all the way up to infinite energies, not even the big bang would be able to be 100% to the left at the zero point, but it would still fit on this graph. There exists more energy in this single space on the graph then everything to the right of it combined. So before a photon could approach this zero wave length mark it would form a black hole called a "kugel blitz", because its energy would be so great from E=MC^2. So that 0 is definitely anything but zero.
