Each pair contributes unique information that is used to build a highly-detailed image of the astronomical object under observation.
Specifically for the cosmological data, the law of selfvariations predicts and justifies: the redshift of distant astronomical objects and Hubble's law, the cosmic microwave background radiation, the large-scale structures of matter in the Universe, the fact that the Universe is flat, the fact that the total energy-content of the Universe is zero, the fact that the very early Universe went through a phase of ionization, the arrow of time in the macrocosm and its breakdown in the microcosm, the fact that the luminosity distances of distant astronomical objects will always be measured larger than the actual distances.
This dust is injected into the interstellar medium and plays a key role in the evolution of astronomical objects from galaxies to the embryos of planets.

By space objects, the military primarily means foreign military satellites, other spacecraft as well as space debris and natural astronomical objects.
In addition, he also wrote a few independent works, whose subjects included cosmology, ephemerides (the study that focuses on celestial navigation by providing the positions of naturally occurring astronomical objects in the sky at any given time), astrolabes, as well as a treatise on the distances and sizes of the planets, and another work on the creation of almanacs.
