The black hole firewall paradox has been vexing physicists for years. But if quantum laws lead to the creation of other universes, the headache disappears, according to Sean Carroll (a.k.a. my Time Lord) and his co-authors. You can also read my 2012 Quanta article on black hole firewalls for more in-depth background to this debate, as well as the accompanying 2012 blog post.

Glowing Auras and ‘Black Money’: The Pentagon’s Mysterious U.F.O. Program. Related: How Accurate Were Tom DeLonge's Alien Claims? Here's The Truth About Those 'Alien Alloys' in The New York Times' UFO Story. Is the government really stockpiling materials in a Nevada building that scientists cannot identify? "I don't think it's plausible that there's any alloys that we can't identify," Richard Sachleben, a retired chemist and member of the American Chemical Society's panel of experts, told Live Science. "My opinion? That's quite impossible." Also: What We've Learned From 60 Years of U.S.-Funded UFO Probes. The newly revealed Pentagon program is certainly not the first federally funded project to hunt for signs of advanced intelligence in the galaxy.
