One possibilty yes, but no. The posters contain a significant part of the answer; actually, the raison d'etre of the puzzle. But it will not make sense by itself!!
Spoiler: Huh Who me? You were very sokanasanah there with 4 x 4 and physicist and 'early'/primordial light.
Hmm I ll appreciate if the clue discussions happened after the solution is posted, ruins the josh of solving.
Clue discussions are fine but there is no point to spoiler tags if half the answer has been openly given away. Sorry Dr S but there is no challenge left in the puzzle anymore.
You sure? That spoiler was vague for me. I wondered whether Ira may still have missed it. Besides, I thought the whole point of that pink-box was that one didn't have to look? Does it not show up in some posts or some browsers etc.?
