A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing – not even light – can escape. Currently, NASA already navigates the solar system by using gravity wells as slingshots to send their spacecrafts to their destinations faster. However, an astronomer from Columbia University has a new theory about how an alien civilisation may be invisibly navigating our galaxy.
In a paper published in the journal arXiv on March 11, David Kipping proposed his new theory.
He claimed an interstellar spacecraft could fire a laser at the gravity mirror of a fast-moving black hole in a binary system.
He argues that, when the energised photon from the laser is whipped back around, it could re-absorb them and convert extra energy into momentum.
His paper reads: “Gravitational slingshots around a neutron star in a compact binary have been proposed as a means of accelerating large masses to potentially relativistic speeds.
