Can gravitational waves be used to transmit data?
Albert Einstein predicted the existence of gravitational waves, but these rhythmic changes in the structure of space-time were not proven until 2016. Could it be possible to impress information on them – like with electromagnetic radiation – and to read this information back without distortion or loss of information? Yes, a team of Russian mathematicians has now shown. This is not obvious, because space-time, as a “medium,” appears to have special characteristics that are not handled by the theory of general relativity. The important question is thus: do these characteristics mean that transmitted data will always be distorted? (altro…)
