RIPPLE EFFECT 35cm / 14" tondo Caused by massive accelerating objects such as a black hole or neutron stars revolving around each other, gravitational waves travel at the speed of light. Passing over space in a fraction of a second, they alter space as one direction gets longer while the other gets shorter by the mere width of an atom. The Sun, planets (including Pluto!) and moon move back and forth by such tiny amounts that we are not even aware of this phenomenon.
