Belligerent refers to a tendency to hostile behavior: A belligerent reporter badgered the politician. Bellicose describes a warlike or hostile manner or temperament: Madison, far from being pushed into war by a bellicose Congress, had to drag his own hesitant party into it. (Garry Wills).
How cold is it in space? That question is sure to prompt the geeks among us to pipe up with â2.7Kâ. For 2.7 Kelvin, or 2.7 degrees above absolute zero, is the temperature produced by the uniform background radiation or âafterglowâ from the Big Bang. But hang on.
NASA researchers are planning to create the coldest spot in the known universe inside the International Space Station. âWeâre going to study matter at temperatures far colder than are found naturally,â says Rob Thompson of JPL. Heâs the Project Scientist for NASAâs Cold Atom Lab, an atomic ârefrigeratorâ slated for launch to the ISS in 2016. We aim to push effective temperatures down to 100 pico-Kelvin.. A new ScienceCast video explores the strange quantum realm of NASA's new Cold Atom Lab.
