Sorry for the ignorant question, as you can see science is not really my strong side. I wanted to know if enough concetration of light could cause an explosion ? There's a fiction character that has light powers, he's practicaly light, the only problem is, that despite him claiming to be true light, he can generate explosions by shooting beams of light - http://kissmanga.com/Manga/One-Piece/Chapter-508?id=250947#10 http://kissmanga.com/Manga/One-Piece/Chapter-507?id=250946#16 Yeah, I know you're probably asking yourself why the hell does it even matter, it's fiction...But go figure, some people just don't understand the definiton of the word "fiction".
