# Flight into a Black Hole: How a Laser Probe Will Embark on a 100-Year Journey

Black holes remain one of the most intriguing mysteries of modern physics. For a long time, astronomers could only observe these objects from a distance, but now scientists are proposing a radical change in approach: sending a spacecraft to a black hole.

The initiative belongs to Cosimo Bambi from Fudan University in Shanghai. His scientific work, published on the arXiv preprint server, describes a technically complex but theoretically feasible scenario for an interstellar expedition.

### Mission Goal: Invisible Giants

The closest known black hole to Earth — Gaia BH1 — is located in the constellation Ophiuchus, at a distance of about 1,560 light-years. It was discovered only due to its gravitational influence on a companion star. However, according to researchers' estimates, there could be up to 100 million stellar-mass black holes in the Milky Way, most of which remain invisible.

Scientists propose searching for such objects by detecting radiation generated when they absorb gas from interstellar clouds. If a suitable target is found at a distance of 20–25 light-years, it poses no threat to the Solar System but opens up a unique opportunity for direct study.

### Laser Instead of Rockets

Conventional chemical rockets cannot handle such a task due to the "tyranny of the rocket equation" — the flight would take thousands of years. The only realistic solution is considered to be the use of a solar sail accelerated by a powerful laser.

A ground-based or orbital laser could accelerate a miniature probe to one-third the speed of light in just 17 minutes. At such a speed, the journey to the target would take between 60 and 70 Earth years.

### Lightning Mission

It is impossible to slow down the spacecraft upon approach, so the mission will take the form of a fast flyby. In a matter of minutes, the probe must collect the maximum amount of data and send it back to Earth — the signal will reach us another 20–25 years later.

The entire expedition will last from 80 to 100 years — exceeding the career span of the scientists and engineers who will initiate the project.

### Engineering Challenge

Currently, humanity does not possess the necessary technologies: gram-scale chips cannot withstand decades of radiation exposure, and ultra-powerful lasers and sails are still in the theoretical development stage. However, scientists consider these problems purely engineering ones.

International working groups are already forming to create the necessary equipment. A major conference dedicated to the first flight into a black hole is planned for the summer of 2027.
