: Universal Gravitational Constant, ISS experimentAbstract:
The Universal Gravitational constant “G” defines the force of gravity – one of the four fundamental forces of nature.
However, the currently accepted value of G is orders of magnitude less accurate than the other fundamental constants,
and ground based experiments differ from each other by as much as 500 ppm in its measurement. This paper describes
a simple, space based experiment that could measure G to within 50 ppm, thereby producing a valuable scientific
measurement using a completely different method and subject to different sources of error. The experiment could also
contribute to the ongoing investigation into the nature of gravity.Share this:
