"400,000 pixels, a 400X increase... near absolute 0 ultra thin electrical wire grid... no resistance until wire struck by single photon when superconductivity shuts down at particular pixel... locations and intensities of all photons makes image... measure signals from all pixels at a time rather than from each individual pixel, reducing number of readout wires... discern arrival time difference of signals as short as 50 trillionths of a second, count up to 100k photons/ second striking grid... capture very weak light signals from space brain"
