Now imagine that the Chandra telescope has a 1.2 meter diameter aperture that those 19 photons passed through.
That represents 1.13 square meters of light collecting area, peering into that expanding spherical wavefront at the point where it is 26+ billion light years in diameter.
That would be a sphere with a surface area of 2,123 square light years. I wonder what it would add up to if you had the 19 photons for all those other 1.13 meter chunks of area in one place.
