change in the speed of light they could provide additional proof to what Galileo had said.
In spite of all attempts they could not measure any differences in the speed of light. This was much to their displeasure because they assumed that either (1) their measurement and experiment was not correct, or (2) that Galileo was incorrect in his assumption that the earth was moving through space.
Einstein comes along 18 years later and proves in his paper on the Theory of Relativity that the ONLY thing, the only matter that is always constant — no matter what the conditions — is the speed of light.
Every other particle of matter, every other force is relative to the condition under which it is measured but only light is a fixed quantity.
Now I am not going to attempt to explain the theory of relativity — first of all because I have only a very limited basic understanding, and second of all it would not contribute to the point of this article.
Suffice it to say this, Einstein was correct – light is an absolute fixed quantity. Every other particle is relative.
Let me hasten to add, the theory of relativity has nothing to do with religion or morality – it is only concerned with physics.
The fact that light is an absolute fixed quantity, never changing, should for all Christians be a very encouraging foundation.
After all, who is the light of the world? Who is the absolute dependable foundation of life?
Jesus Christ our Lord, our Savior! He is the true light, coming to enlighten all of mankind. (John 1:9) He is the absolute, the one on whom we can depend. He is the Light of the world, and those who follow Him will not walk in darkness but will have the light of life. (John 8:12)
This ever-changing world is filled with relativity; Jesus is that never-changing, absolute light. He is the light for our path. There is no need to walk in darkness when Jesus is the light. The absolute light is always dependable, the same yesterday, today, and forever. (Heb. 13:8)
You can always depend on the Light.
