The Milky Way galaxy's stunning arc is visible on moonless nights. Many of those stars are at vast distances, some over 50,000 light-years away. In Psalm 19 King David reflected on this cosmic splendour, interpreting the night sky as a declaration of God's creation. I explore its significance to the biblical creation worldview.
The only three measurables in galactic astronomy are the position, luminosity and spectrum of the source light received in our telescopes. There is no distance information without unprovable assumptions, hence no direct measurement of size or age of the universe. Thus we may conclude it is young in agreement with the Bible.
Does the fact that we see light from very distant galaxies prove that the one-way speed of light is finite? Dr. Jason Lisle responds to this question. The conventionality thesis plays a critical role in understanding the issue, suggesting that measurements usually assume an isotropic light speed.
