Just because it's summer time it doesn't mean you're suppose to stop writing! This is great viewing weather for astronomy. This is a great time to sit back and curl up with your laptop on a family vacation and get some writing done!!
Well here's some research in the area of gravitational waves and stuff. Think Star Trek warp drive stuff...in the biz they call it hard scifi.
Gravitational Waves
Computer model of the gravitational waves coming from the collision of two black holes. Image: MPI for Gravitational Physics/W.Benger-ZIB Vibrations in the fabric of spacetime which travel at the speed of light and are predicted by Einstein's general theory of relativity. The most intense gravitational waves, resulting from large masses undergoing high accelerations, are expected to be produced when stars collapse or matter falls into a black hole. Although they have yet to be detected, evidence for their existence has come from observations of the only known binary star in which both components are neutron stars. A gradual, minuscule increase in the orbital period of this system can be accounted for exactly if energy is being lost by gravitational waves at the rate predicted by general relativity.
