Walkabout the Galaxy
Korea's Moon mission; Large Hadron Collider; W bosons
Astrophysics and Astronomy | Physics
Korea sends its first mission to the Moon, and Mars sent a very old piece of itself to Earth. Meanwhile, the Large Hadron Collider is finding more odd collisional products than expected: the rate of creation of three W bosons is a bit high. Do you ever feel that there’s something wrong with the world? Maybe the LHC is getting a glimpse of new physics. Join us for all that, space chorizo, and the Jeans length with a full set of four astroquarks.
Whether you like your jeans bunched up at the cuff, tapered to your ankle, or cut off mid-thigh, for your star formation needs, you'll want to get the original Jeans length. Depending only on the temperature and mass density of an interstellar cloud, and a few universal constants, calculate the Jeans length to determine if your cloud will collapse under its own weight like a pair of acid-washed pants, or expand to a new equilibrium like stretchy demins. With options for oscillation, wavelengths, and cascading fragmentation of giant molecular clouds, check your Jeans length for your fashionable walkabout the galaxy. Jeans length, be an outsider (L.L. Bean).
