Astrophysics and Astronomy | Physics
Beware the Squire of Gothos for the Kepler mission has discovered 4 more new free-floating planets. LIGO has observed the first collision between a black hole and a neutron star, and the ocean of Enceladus just might harbor life. Learn about these astronomical developments and much more, including a Venus exploration trivia and science fiction film rants.
If you hate to be pinned down, try exchanging your point-based view of the world around with a stringy approach that gives you the extra degree of freedom afforded by having an entire dimension to play around with. That's right, with string theory, you can be an open string or a closed loop and your shakes and wiggles tell the world all about you. As an added bonus, when you move through space, your trajectory is a surface rather than a line, and if you want to get really freaky, get a super string and a bosonic string and make yourself a HEDErotic string. So whether you're looking to unify all of physics or you're just looking to stretch yourself into some extra dimensions, try string theory. String theory, it keeps going and going. (Energizer).
