Can gravitational waves be used for communication?

Currently, there are several technologies that provide communication between people in remote areas via telephone, radio or internet. For example, when using radio frequency waves for radio sound transmission, light is widely used on the light fiber optic internet to transmit high speed data. Can gravitational waves be used in this process?

A new study on the Arxiv Prepress Server is investigating the likelihood of using gravity waves as a communication tool. It is carried out by researchers at the Cambridge University Group Group Internet in the UK. The research is investigating whether these distortions in space can be applied to human technology in the future.

The study titled “Gravity Communication: Foundations, Conclusion Status and Future Vision” analyzes the principles and potential practices of this approach.

According to the authors, Houstianfi Wang and Ozgur B. Akan, Gravity waves can provide a stable signal even at long distances. But what kind of communication is this technology applied? The proposal is to develop a fast and reliable transmission system to support spatial tasks beyond the solar system.

Gravity waves were first observed in 2015, when he identified the GW150914 signal in LIGO (Laser Interferometer Gravity-Waldar Observatory). This phenomenon took place about 1.3 billion light years from Earth.

“The discovery of gravity waves opened a new window of observation for astronomy and physics, and offered a unique approach to explore the depths of the universe and excessive astrophysical phenomena. In addition to its effect on astronomical research, gravity waves attracted great attention as a new communication paradigm. ”

The existing forms of communication are effective, but there are still limitations. For example, radio transmission, precipitation affecting the signal and other meteorological phenomena may experience parasites caused by region climate. In fact, most communication technologies depend on the effects of electromagnetism, including radio, Wi-Fi, Bluetooth, communication satellites.

What are gravitational waves?

According to Ligo, gravity waves are space -time fluctuations produced by various cosmic phenomena. Although they were detected only in 2015, German physicist Albert Einstein predicted the existence of waves in his most famous work in 1916: the theory of relativity.

For example, Large objects such as neutron stars and black holes can produce disorders that cause gravity waves at space time. These fluctuations spread at the speed of light and allow you to examine some of the most extreme phenomena in the universe; Therefore, it is even possible to test the estimates of general relativity.

In short, when these objects are mutually in orbit, they produce a movement that causes fluctuations in space time. To explain, imagine a stone falling into a lake: when touching the water, it creates waves spreading from the point of effect. Gravity waves similarly, but work in space. However, unlike mechanical waves, they are invisible and cannot be detected directly with spatial telescopes.

“Stronger gravity waves, collision black holes, supernovs (large stars exploding at the end of their lives) and the collision are produced by disaster events such as neutron stars. Other gravitational waves are described in an official ligo broadcast caused by the rotation of neutron stars without perfect spheres and even with gravity radiation scrap created by Big Bang.

Communication through gravity waves

The team explains this A gravitational wave -based communication network can maintain signal quality even at cosmic distances such as the regions beyond the world and the solar system. According to researchers, this technology may be necessary for future space mission, because it may allow communication with unmanned ships to discover other galaxies.

Unlike the electromagnetic waves used in existing communication systems, gravity waves do not lose its intensity with increasing distance because they cross the cosmas without distributing energy. However, there are important difficulties for the development of this technology; Therefore, for now, it is impossible to develop such a system.

The main challenge is currently, right now There are no technologies or instruments that can produce artificial gravity waves. As stated, these fluctuations arise naturally from extreme events in the universe, such as the collision of black holes. So, many obstacles should be overcome before this idea becomes applicable.

Some experts have already managed to produce gravity waves in the laboratory, but their densities are so low that the existing instruments cannot detect them. Because of this and other limitations, Writers emphasize the need to develop more sensitive detectors, create methods to modulate signals and deepen information about artificial production of these waves.

“This article offers a comprehensive appearance of the latest foundations and progress in the communication of gravity wave, including a detailed historical examination of the production and detection of these waves. The main issues include, evolution of the sensitivity of detectors, production methods, modulation techniques and gravity communication channel. ”

In addition to helping to understand black holes and star collisions, these fluctuations in space time can bring answers to one of the greatest puzzles of modern physics. Do you want to know more? Let us consider the opportunity to understand how gravity waves can answer some of the mysteries of the dark matter. Until next time!
