While the concept of warp drives may seem like something out of science fiction, recent research suggested that these hypothetical faster-than-light engines could produce detectable gravitational wave signals and detect alien civilisations.&nbsp;

The idea of using warp drives for interstellar travel has long captured the imagination of scientists and science fiction fans alike. First proposed by physicist Miguel Alcubierre in 1994, the concept involves distorting spacetime to allow a spacecraft to travel faster than the speed of light without violating the laws of physics.

However, the practical realisation of warp drives faces significant challenges, including the need for exotic matter with negative energy density to maintain the warp bubble. Despite these obstacles, physicists continue to explore the theoretical underpinnings of these spacetime-warping engines.

Now, a new study published on the preprint server arXiv has delved into the potential gravitational wave signatures that could be produced by a warp drive containment failure. The researchers, from institutions in the UK and Germany, simulated the collapse of a warp bubble and analyzed the resulting gravitational wave emissions.

"We see a burst of gravitational-wave radiation leaving the collapsed remnant of the warp bubble," the researchers said. They found that the unique characteristics of these gravitational waves would differ from the signals typically associated with events like black hole or neutron star mergers.

While the frequencies of the gravitational waves from a warp drive collapse would be too high for current detectors like LIGO to observe, the researchers suggest that future observatories, such as the planned Laser Interferometer Space Antenna (LISA), may be able to pick up these distinctive signals.

The prospect of detecting gravitational waves from warp drive malfunctions has intriguing implications. "Physically, this could be related to a breakdown in the containment field that the post-warp civilization (presumably) uses to support the warp bubble against collapse," the researchers noted.

Warp drives may reveal alien civilisations by sending gravitational waves through universe

Ever wondered if you can travel faster than light? It may not be too far from reality, after all. How, you wonder? It's simple - a warp drive!

Scientists have historically discouraged others from taking the idea of warp drives too seriously, but a new study suggests that travelling faster than light may be possible by taking advantage of a "loophole" in general relativity, which refers to laws of gravitation posited by Albert Einstein.

Basic laws of physics make warp drives impossible, which is why its common depiction has remained restricted to science fiction films and series. 
 
What is a warp drive? 
A warp drive is a fairly simple concept. In space, everything falls secondary to the speed of light, and nothing can flourish over it except space-time. To achieve warp drive, scientists intend to warp spacetime surrounding an object.

Essentially, to be able to travel faster than light, one needs to spiral the object into a contraption of negative energy. Due to this, space and time behind the ship would expand, while space and time ahead of the object would be compressed. This was first envisioned by Miguel Alcubierre, a Mexican scientist in 1994. 
 
But there's a catch - laws of physics don't make room for negative energy. Even then, it is not entirely impossible to conjure negative energy. Scientists believe that to achieve this, energy would need to be borrowed from a vacuum. In theory, this would open the gateway for negative mass and negative gravity - essentially the opposite of what we experience in our lives.

Even then, the idea of successful warp drives remains fixated in theory. Many continue to believe that warp drives may never be physically possible.

“This, however, is no longer correct,” Alexey Bobrick, an astrophysicist at Lund University told ZME Science. Currently, a group of researchers in Sweden are working to make warp drives a reality! How, you say? By simply not requiring negative energy, and basing the science behind it "physical principles known to humanity today".
