Dan the physicist

A guy who knows a thing or two about light. I wonder about the significance

of his comment about the nature of light on the island, that it seems to 
refract differently. Does that lend credence to the supposition that
there's 
some sort of force field around the island that renders it hard to detect?

The purple sky would be something going amiss with that field briefly? 
Fascinating stuff.
