Two Harvard scientists are now speculating that fast radio bursts (FRBs) that have traveled from the far reaches of the universe to Earth could be aliens. Furthermore, they believe they may have been leaked from an alien spacecraft that would be roughly the size of a planet.
The bursts were first detected in 2007, and since then 17 others have made their way to Earth. The scientific community agrees that the bursts had descended from a distant galaxy. Since their discovery, they have been deemed as fast radio bursts and emit as much energy in one second as the Sun does in 10,000 years.
Since detected, scientists have been scrambling to understand the origin of the bursts, and a more recent suggestion has left the scientific community stunned. According to professor Avi Loeb and his colleague Dr. Manasvi Lingam, the FRBs could be evidence of extraterrestrial life forms that may have leaked energy from unfathomably powerful transmitters capable of sending giant light sail ships on voyages between stars.
Loeb stated that “Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence. An artificial origin is worth contemplating and checking.”
In a study, that has now been published in the Astrophysical Journal Letters, both Loeb and Lingam have attempted to understand whether or not it would be possible to build a transmitter with enough power that it could be detected galaxies away. What they found was that a solar-powered system could generate an amount of energy necessary if it used twice the size of the Earth to capture the rays of the Sun.
In order to prevent the craft from melting, a massive amount of water-coolant would also be necessary. Why would they need such a massive solar powered energy plant? To drive interstellar light sails. And while the idea may seem to be a bit outlandish, it could indeed be plausible. Especially considering our lack of understanding regarding the origin of the bursts. Just as Professor Loeb noted, “It’s worth putting ideas out there and letting the data be the judge.”
