Here's the story: http://news.bbc.co.uk/1/hi/sci/tech/4907308.stm Yes, I read this: ``Using only present-day terrestrial technology, a bright, tightly focused light beam, such as a laser, can be 10,000 times as bright as its parent star for a brief instant. Such a beam could be easily observed from enormous distances.'' But Jimminy Cricket, what about the FAA equivalent on these alleged alien worlds? Just like our TV and radio shows, the old DEW line radars, and the deliberate "here we are" tightcast to M13, we've shot off plenty of bright lasers into the galaxy; look up "Laser Guide Star." |
