In January 2025, physicists from CERN and MIT joined forces to create the first-ever gravitational antenna—a device that transmits information using modulated gravitational waves. Unlike radio or light, these waves pass through any obstacle—planets, stars, black holes—without distortion or delay.

The technology is based on next-generation quantum interferometers capable of detecting spacetime fluctuations with an amplitude of 10⁻²¹ meters—the equivalent of measuring the change in distance from Earth to Alpha Centauri with an accuracy of a human hair. Transmission uses an array of rotating superconducting rotors, creating controlled “pulsations” of the gravitational field.
The first message was sent from Geneva to Tokyo—through the Earth. The transmission time was 0.04 seconds. It contained just three words: “Contact established.” But this is the beginning of a new era of communications. In the future, gravitational links will allow us to control probes beyond the event horizon of black holes and coordinate colonies on Mars without delay.
The advantages are enormous. The signal cannot be intercepted, spoofed, or blocked. It does not produce electromagnetic radiation that is hazardous to health. And it works in conditions where radio is silent—for example, inside nuclear reactors or in deep mines.
NASA is already testing a miniature version of the antenna for satellites. The first “gravitational internet” between the Moon and Earth is planned for 2026.
