In assenza di emozioni tutto ci sembrerebbe uguale, quindi ci ritroveremmo nella situazione paralizzante di non riuscire a compiere una scelta. Gli scienziati stanno quindi cominciando a capire che le emozioni, lungi dall'essere un lusso, sono uno dei fondamenti dell'intelligenza.

Hollywood movies, however, have brainwashed us into thinking that we can defeat the alien invaders if they are a few decades or centuries ahead of us in technology.

To make Harry Potter invisible, one would have to liquefy him, boil him to create steam, crystallize him, heat him again, and the cool him, all of which would be quite difficult to accomplish, even for a wizard

It would take a civilization far more advanced than ours, unbelievably advanced, to begin to manipulate negative energy to create gateways to the past. But if you could obtain large quantities of negative energy—and that's a big “IF”—then you could create a time machine that apparently obeys Einstein's equation and perhaps the laws of quantum theory.
