Question

Joseph Weber designed a series of devices to detect ripples in spacetime, announced that he had detected gravitational waves. He built several versions of his devices and they all detected the waves. When other people tried to build similar devices, none of them detected anything at all Joe's evidence was ignored by the scientific community because called gravitational waves. After several years of effort, Joe O A Joe was an Electrical Engineer and did not belong to the physicist club. Scientists would not believe there was a possible source for gravitational waves strong enough to register on Joe's detectors OCJoe's observations were not reproduced ement? OD Joe's observations were sloppily done and not convincing

Answer 1

A observation must be repeatable and reproducible by the community to tell if the observation is correct. So, the reason for ignorance of Joseph's observation: - (c) Joe's observation were not reproduced There is no green star . Or if there is any, other observes must find it out as well. So, most suitable answer should be. (C) Other people look near They do not find green star, attack her repot, deem if so be fraud.
