Is it time travel? Time travel FORWARD is allowed by Special Relativity, Maxwell's Equations & QED. Or...Can we view the Universal Wave Function of all things via a system of engineering that allows temporal gravitational lensing? What if we can LOOK back in time? Einstein himself discovered gravitational lensing. Assume a device, built in higher dimensions, but visible to our 3 dimensional mammalian brains as a cube (in hyperspace it would be a tesseract, or hypercube). We could view probabilities & outcomes. Would need 2 hypercubes, if you wanted audio of the events. Like a Looking Glass...
