Now, with the emerging field of gravitational wave astronomy, scientists will be able to study objects and events that where previously unobservable; such as the merger of ultra-compact massive objects like black holes, the event horizon of black holes including their Planck-scale structure, and perhaps some of the earliest events in the universe. Such data will be invaluable to advancing unified physics. The current ground-based method for gravitational wave detection uses extremely sensitive interferometers that can detect changes in position of the sensors of better than one part in a billion trillion. They are precise. Yet, there is an inevitable introduction of noise into the detection system due to the tiny vibrations from natural and man-made sources. These vibrations, which distort the ability of the sensors to detect the fine changes in position due to passing gravitational waves, often occur in a frequency range that may contain a plethora of information about many of the previously unobservable astronomical and cosmological phenomena. As such, one solution is to get off the surface of the Earth and perform the experiments in space -- similar to our recently reported story on creating the coldest spot in the universe. In addition to being isolated from the vibrational noise of the Earth's surface, the experimental apparatus will utilize a new detection method. Instead of measuring the changes in separation of detectors, a research team have proposed using precise atomic clocks mounted in two satellites to measure the minute motions of sensors due to the Doppler effect as gravitational waves pass through. This new detector concept will be particularly useful in studying the low frequency gravitational waves that are often "drowned out" by the vibrational noise of Earth-based interferometers.
