What was the speed of light 2 billion years ago? (On the other hand, there CAN exist sufficient data to show that it is changing. This is a point about sufficiency of data to prove a long-term or a short-term change. I am not arguing for or against CDK.)
So what does the creationist theory say as it pertains to the speed of light? How can we test this theory? What experiments can we run to determine if the speed of light has changed in the past, if that is what the creationist theory proposes?
Assuming redshift is entirely due to recessional speed also leads to some fairly incongruous conclusions, like the idea that the expansion of the universe (if it is expanding) is accelerating. Really? How? By what process?
How does the creationist theory of light explain the relationship between the redshift of a galaxy and the distance to the galaxy as measured by standard candles (e.g. type Ia supernovae)? How does the creationist theory of light explain the changes in gravitational lensing due to dark matter:
quote:In a method similar to taking an X-ray of the body to reveal the underlying skeleton, the technique, known as weak gravitational lensing, allows astronomers to see how light from distant galaxies is bent and distorted by the dark matter as it travels towards earth.
They can then map the dark matter structures, which make up 80 per cent of the universe.
I said nothing about atheism. I simply said that "something (atheism, creationism, naturalism, Hinduism) does not become science merely because a scientist adopts it as his faith."
We aren't talking about faith. We are talking about the data that the creationist theory of light must explain within a testable framework, otherwise called a scientific theory. Let's ignore all of the modern theories that scientists have put forth to explain this data. Tell us how the creationist theory of light explains this data.
There are creationist theories about light, such as that proposed by Russell Humphreys in his book 'Starlight and Time, solving the puzzle of distant starlight in a young universe'. Also another by John Hartnett in his book 'Starlight, time and the new physics'.
What testable predictions do these theories make, and how does one test them? For example, from my experience the theory put forth by Humphreys requires that distant galaxies be blue shifted. They are exactly the opposite. They are red shifted.
