Ask Ethan #108: Is there any “instant” sunlight? (Synopsis) [Starts With A Bang]
“Birds sing after a storm; why shouldn’t people feel as free to delight in whatever sunlight remains to them?” –Rose Kennedy
It’s a good thing that sunlight doesn’t reach us simply from its moment of creation in the core of stars, otherwise we’d be bombarded with lethal gamma rays, rather than the life-giving UV, visible and infrared light we actually experience.

But that doesn’t mean it isn’t possible that the ultimate form of direct sunlight — light from a nuclear reaction in the Sun — to reach us, does it? Today’s Ask Ethan focuses on the possibility of “instant sunlight” in exactly that fashion.
