The Atheist Blogger

A few days ago I mentioned how wrong Ray Comfort was when he remarked:

Light is invisible. We can’t see it.

I’ve checked back to Ray’s blog regularly to see what he does about this basic misunderstanding of physics and how the eye works, and to check up on the comments that his post got (almost all of them were mocking him). He appears to have now edited the article so it reads:

The essence of “white” light is invisible. We can’t see it. Despite this, science has taught us that it’s actually made up of seven beautiful colors that are undetectable to the human eye until they are refracted through a prism. Of course, we know that the seven colors are the amazing colors we see in a rainbow–red, orange, yellow, green, blue, indigo and violet.

Nice bit of rewording he has done. Unfortunately it makes even less sense now than it did before his edits. What exactly is the “essence” of white light? Is he talking about the spectrum? That’s not invisible either. In fact that’s exactly how we see colours.
