To Deflect Asteroids From Earth, Deploy Paintballs By The Ton | Popular Science:

 "Paek's strategy is fairly simple: Five tons of paintballs full of white powder would be launched towards an asteroid from a nearby space craft, 20 years in advance of a possible collision with Earth. The force of the pellets hitting the object will push it off course, but also the reflectivity--the albedo--of the white paint would increase, and over time the photons bouncing off the surface would also force the asteroid away from our planet. How has no one ever thought of this before?"

In 2007, AT&T deleted Eddy Vedder’s criticism of George W. Bush during a webcasted Pearl Jam concert.  Although AT&T was technically acting in the capacity of a content provider, content providers and Internet providers have merged dramatically in the past few years, resulting in the lines becoming uncomfortably blurred. This sort of censorship threatens both innovation and free speech."   ...ero. Related articles In Harm's Way: The Dangers of a World Without Net Neutrality Resetting the Net. E.F.F.
