Is Anti-Gravity Possible?

"By now you've probably heard about Neil deGrasse Tyson's reboot of Cosmos, running every Sunday night on FOX (yes, that FOX) for the last few weeks. It was a controversial step to take Carl Sagan's beloved early 1980s-era tour of the universe and revamp it for the modern era. According to most reviews (and an informal poll of my astrophysicist colleagues), so far it looks like Neil is doing St. Carl (as I like to think of him) proud, giving a whole new generation of viewers a big picture view of ... well ... the big picture."

"But what happens after the last eye-popping rendering of the Milky Way fades from viewers' flat-screens and Tyson's teardrop-shaped starship sails off into the distance? Where do folks turn who — like the monk-philosopher Giordano Bruno featured in episode 1 — are hungry to learn even more?"

"The answer is simple. Once their journey with Neil is over they can begin a new one with Brian. That's Brian Greene, the string-theorist-turned-writer who, along with Tyson, is one of the few people in the world who can honestly lay claim to the title "super-famous scientist." This month Greene launched the World Science U (WSU) with the goal of offering an online destination for people with big questions and an appetite for big answers."
