This latest article is a good example of insufficient and even wrong information supplied... excellent wayto create confusion.
Pay attention to a mechanism of this explosion, they are described differently... If reader is not careful, and reads only last one of them, he/she may conclude that somehow photons could be splitted itn two?!
"In stars as massive as the parent to SN 2006gy, the inside is predicted to have been hot enough to split photons apart. This equates to a loss in radiation energy, and so to a loss in the internal energy source that stabilizes the star against the effect of gravity. The result is that the whole thing explodes. "
What is worse, there is a contradiction: loss of internal pressure causes the star to explode!

Popularization of science is really a hard wok... rarely done properly.
