Walkabout the Galaxy
Large Hadron Collider, subatomic particles
Astrophysics and Astronomy | Physics
The Large Hadron Collider announced five new subatomic particles recently. Top astroquark Jim Cooney is our go-to quark for all things quarky, so he explains what's going on with these new particles. Charm astroquark Addie Dove gives us the latest rocket news, and Strange astroquark Josh Colwell discovers that there's something good about "Starship Troopers". Tune in for the latest news in astronomy, from the planetary to the cosmological, nerd news, space trivia, and "what's on Josh's whiteboard" on each episode of Walkabout the Galaxy.
We know how it is, all caught up in the fuss over solar power, or looking at the international thermonuclear experimental reactor, or ITER, and the prospect of fusion power. And speaking of atomic power, maybe you think nuclear bombs are all that, but don't forget about kinetic energy. One kilogram of mass falling to the ground at a measly 2.9 kilometers per second, packs as much kinetic energy as a bomb of TNT of the same mass. Try dropping that from orbit and it packs more than 10 times the punch of TNT. So if you'd like to invade another planet and wreak some serious havoc, don't bother with bombs and guns, just bring some rocks, or better yet, drag some asteroids over once you get there and drop them on your victims. Were looking at you, Independence Day, Colony, and Signs. Kinetic Energy, tried and true.
