Suppose the Zika virus endangered "only" pregnant women and the unborn, as we were, for a long while, assured. That would be horrible enough. The situation may be worse than that.

(But might the em drive produce reactionless thrust, even though no one -- not even its adherents -- claims to understand how? Even though the claimed thrust is very slight? Yes, it's possible there's something new -- and that the something isn't a flaw in the experimental setup, as turned out to be the explanation for onetime reports of FTL neutrinos. To eliminate lots of experimental variables, one possible test of the em drive would be to put the device into orbit [where gravity won't dominate/disguise its purported effects], turn it on, and watch it work -- or not. And maybe that'll happen. See "The Impossible Propulsion Drive Is Heading to Space: Enough argument. It's time to actually test this crazy thing.")

So how about the next change (after the dismal failure of 3DTV) that industry hopes we'll embrace? If 1K lines are good, 4K lines are even better ... right? Wrong -- at least given a typical viewing space such as your family room. See "4K Resolution Rules TV Screens But Look, The Emperor Has No Clothes."
