Within this Great Wall are large numbers of galaxies. Yet from the earth without the aid of a powerful telescope, it would appear as a tiny star. In comparison, Our Milky Way Galaxy would appear like a tiny little speck in the midst of a sea of galaxies within this Great Wall. Astronomers have been able to detect galaxies over six billion light years away from earth. In other words, if a certain star within a galaxy should explode,that is, become a super novae, it would take over six billion earth years to know anything about it.
Astronomers claim there is a limit to our universe.
Humanly speaking a span is the distance from the tip of the little finger to the tip of the thumb when the hand is stretched out, a distance of about 9 inches. This implies that God is the One responsible for stretching out or expanding the boundaries of the universe with His hand. This implies that God has complete control of every galaxy, star, pulsar, quasar, planet, moon, etc., within our universe. Each one would respond to His word or command. If God should command our sun which is travelling upon a trajectory orbit within our Milky Way Galaxy to slow down or speed up, it would respond accordingly.
