Femto photography allows for a trillion frames per second and can capture light as it moves across the room. http://www.highpants.net/femto-photography-capturing-individual-photons-in-motion/ My experiment to detect for the aether would involve taking a picture with a femto camera of a split light beam along a 180 degree axis, and measuring with a ruler in the picture if the light travels outward faster in one direction then the other. One would only expect the light to travel slower or faster by a a fraction of a percent because the movement of the earth through the universe is a tiny fraction of the speed of light. In the Michelson and Moorley experiment that originally measured for the aether moving across earth, the light bouncing back on the same path it was sent out on would cancel any momentum gained or lost from traveling with or against space-time on its initial path, and cause all light beams to return at the same time. That's why it didn't work.
