A Scout Probe Will Uncover the Mystery of the Nearest Black Hole ⚡ экспресс
This study evaluates the possibility of testing the nature of a compact object using probes in orbit around the nearest black hole. Earlier work showed that an interstellar mission could be feasible within a few decades, despite its speculative nature and technical hurdles. A century-long mission would require enormous resources, so it's crucial to know if it could explore black holes and general relativity at a level unreachable for any observatory in the Solar System anytime soon. In this paper, we assume the spacecraft can brake at the target and conduct a preliminary analysis of how orbital probes can put the nature of compact objects to the test.
A probe is to be sent to the nearest black hole. A hundred years of flight — and it will enter orbit around a mystery. The key question: black hole or neutron star? The former has no surface, just a bottomless pit. The latter has a solid crust of super-nuclear density.
The trajectory will provide the answer. Curved spacetime around a black hole dictates one path for the probe, as predicted by Einstein. A neutron star influences it differently. It's like a boat in a whirlpool: the vortex pulls differently than an underwater mountain.
The nearest one is Gaia BH1, 1,560 light-years away. The probe would need 5% of light speed, unthinkable today. And its signal would take another 1,560 years to travel back — only distant descendants will see the answer.
🎯 The nearest black hole, Gaia BH1, is 1,560 light-years away. To reach it in a century, a probe would need to travel at about 5% of the speed of light — a hundred times faster than any current spacecraft.
🎬 As in 'Interstellar', orbiting a black hole becomes the key to understanding gravity.
