Space is enormously stiff, can't squish it: Nobel Laureate
MIT Professor Rainer Weiss, who jointly won the 2017 Nobel Prize in Physics for gravitational wave detection, said in an interview, "Space is enormously stiff. You can't squish it". Describing the challenge scientists faced, Weiss gave an example, if gravitational waves came from Sun to Earth, an accuracy equalling width of a hair would be needed to make the detection.
