One Ivy League Astronomer says humans could achieve fuel-free interstellar travel by harvesting energy from binary black holes in a brand new method dubbed the 'Halo Drive.'
Theoretically, said David Kipping, an astronomer at Columbia University, aliens could already be using that technology without our knowledge.
The Halo Drive method of propelling a spacecraft would work by utilizing 'gravitational mirrors' – a region of a black holes that swallows up matter and shoots it back out in exactly the same direction – to absorb the holes' energy.
The Halo Drive theory uses black hole energy to propel space crafts beyond the speed of light. Artist's impression of a black hole is pictured
'The search for intelligence amongst the cosmos is often guided by considering the possible activities of hypothetical advanced civilizations and the associated technosignatures that would result,' said Kipping in a study published in the journal AirXiv.
'Along these lines, this work has considered how an advanced civilization might utilize the light sailing concept to conduct relativistic and extremely efficient propulsion.'
Scientists have observed that when photons enter a gravitational mirror and are subsequently shot back out, they not only gain velocity from their journey, they also retain some of the kinetic energy from the visit.
Kipping says using those returned photons, which are called 'boomerang photons,' interstellar travelers could theoretically use the harvested energy to travel at a velocity 133 percent greater than the black hole.
This method of harvesting energy from black holes would not only avoid having to tread dangerously close to the gravitational void – astronauts have tapped black holes as a type of slingshot to help propel objects into space for ages – they would also be extremely hard to detect.
'A civilization could exploit black holes as galactic way points but would be difficult to detect remotely, except for an elevated binary merger rate and excess binary eccentricity,' said Kipping.
As a result, Kipping said, a civilization that has the means to travel close enough to a black hole could theoretically be deploying this type of method of interstellar transit without our knowledge.
Another major benefit of the Halo Drive over other proposed forms of interstellar travel, posits Kipping, would be shedding the need for a massive fuel source.
While other theoretical forms of travel require a spacecraft to accelerate to what is called 'relativistic speed' – a speed comparable to the speed of light – the Halo Drive would subvert the need for any prior energy other than the light harvested from a black hole.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.
Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
