Scientists plan new space mission to observe quantum gravity: "A University of Aberdeen scientist is leading this research to show, for the first time, how quantum gravity may be observed in space. According to Dr Charles Wang, a Reader in the College of Physical Sciences and a member of the Aberdeen Centre for Applied Dynamics Research, space-time is constantly deformed by ‘gravitons’ - particles that are believed to mediate gravity at an extremely small scale. This is just like the way in which pollen grains or smoke particles in air have a random ‘Brownian motion’ as they are buffeted by much smaller molecules. He said: “By observing these tiny distortions in a quantum experiment, we think it will be possible to extract information on the ultimate theory of space-time.”

Dr Wang explains that there is a widely held perception in modern physics that the perpetual warping of space-time due to its quantum properties is too small to be seen in any normal circumstances. "
