Mrs. Chatman's items #2 and 3
Mrs. Chatman makes some very weird assertions. One that is outstandingly weird is;
"2. It is not known what light really is or if it travels the same speed through out time and space."
What light is, is really well known. It has been really well known for many decades. The scientific understanding of light is called electromagnetic theory. It is a central part of physics. Electromagnetic radiation ranges from the low of radio waves to the upper extreme of high energy gamma radiation. Light, limited to what we humans can typically see, falls in the frequency range of 380 nanometres to about 740 nm. For more information about the physics of light, read up on "photons."
We are also certain that the speed of light had been constant for over 6 billion years at a minimum. This isn't from theory, but from direct measurement. See my short item "Are constants constant?"
Mrs. Chatman's argument for a 6,000 year-old Earth and Universe item #3 seems to feature a brief, and not very well stated description of some parts of general relativity. There is her confusion about the differences between relativity, and quantum mechanics. That is easily forgiven since most people (even physicists) can be confused. What is totally missing is why these are an issue relevant to young earth creationism? I wonder if she just needed some fillers to get to "10 arguments." Maybe 10 is a magic number.
