No ship that small has a cloaking device!

Science imitates Star Trek, again. Physicists Nicolae Nicorovici and Graeme Milton have published a paper in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences outlining a theoretical means for constructing a cloaking device. A superlens constructed from a metamaterial with a negative refractive index could be used to create a resonance that cancelled the light coming off of a (very small) object, rendering it invisible.

Come on big gravity waves... No whammies!

Do Gravity Waves Exist? This is one of the big unanswered questions in physics. Gravity telescopes such as the LIGO and the Geo 600 may soon tell us. These massive detectors are sensitive to a displacement of 1 part in 1000000000000000000000-- that's like "measuring a change of one hydrogen atom diameter in the distance from the Earth to the Sun." Such a discovery would mean a tremendous boom to science. And big cash payouts to those who put their money where there mouth was.
