US scientists detect biggest explosion ever

"'I was stunned to find that a mass of about 300 million suns was swallowed,' said Brian McNamara of Ohio University, lead author of a study on the discovery published in the latest issue of Nature."

The known universe is chock-full of high-energy events similar to this. Could some of them be unrecognized signs of intelligent activity? We tend to think of proof of ET intelligence arriving unambiguously. Maybe it's more likely we'll stumble upon alien megascale engineering and prematurely attribute it to "normal" cosmic processes. (The "Red Rectangle," for example, appears tantalizingly like a vast artificial structure.)
