This article explores the potential of using gravitational waves for communication, highlighting the advantages it could offer over traditional electromagnetic communication. It discusses the challenges and opportunities in generating and detecting artificial gravitational waves, outlining the current state of research and future directions.
This illustration shows the merger of two supermassive black holes and the gravitational waves that ripple outward as the black holes spiral toward each other. Image Credit: LIGO/T. Pyle, it opened a whole new window into the Universe. Before that, astronomy depended on observations of light in all its wavelengths.
“Gravitational waves can maintain consistent signal quality over immense distances, making them suitable for missions beyond the solar system.”“The discovery of gravitational waves has opened a new observational window for astronomy and physics, offering a unique approach to exploring the depths of the universe and extreme astrophysical phenomena.
There is plenty of theoretical work behind GWC but less practical work. The paper points out what direction research should take to bridge the gap between the two. “High-frequency gravitational waves, often generated by smaller masses or scales, are feasible for artificial production under laboratory conditions. But they remain undetectable due to their low amplitudes and the mismatch with current detector sensitivities,” the authors explain.
There are also unique noise sources to consider, including thermal gravitational noise, background radiation and overlapping GW signals. “Developing comprehensive channel models is essential to ensure reliable and efficient detection in these environments,” the authors write. It might seem as if GWC is out of reach, but it holds so much promise that scientists are unwilling to abandon it. In deep space communications, EM communication is hamstrung by the vast distances and interference from cosmic phenomena. GWC offers solutions to these obstacles.
