We are able to measure the distance of remote cosmic objects based on cosmological redshifts. We can measure the distance of a receding sound source by recording it's frequency, if we know the original wave character, medium etc (Doppler). What is necessary in both the cases is movement of the object, without which we cannot measure the distance even if we record the emitted light/sound. I am opening this thread for a discussion to find out if it is possible to ascertain the distances of objects (sound sources and light sources) by any other means. (Leaving aside geometrical two position based measurement of a light source). I am just trying to ascertain if cosmological redshift is a nature's sole gift to us to ascertain such vast distances.
