Caption: A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the other end of the cosmos. Their paper describing the device and process was published in the prestigious physics journal Physical Review Letters. Andrew Geraci, assistant professor in the University of Nevada, Reno physics department, demonstrates an apparatus that is of part of an experiment that uses similar technology to his gravitational wave detector. This equipment uses levitated nanospheres in an optical trap for investigations of the gravitational force at the micron length scale, where some theories in high-energy physics predicts there will be a deviation from the Newtonian inverse square law of gravitation.
