Aliens are the Source of Fast Radio Bursts?



Alien are the Source of Fast Radio Bursts?

      Bizarre flashes of cosmic light may actually be generated by advanced alien civilizations, as a way to accelerate interstellar spacecraft to tremendous speeds, a new study suggests.

Astronomers have catalogued just 20 or so of these brief, superbright flashes, which are known as fast radio bursts (FRBs), since the first one was detected in 2007. FRBs seem to be coming from galaxies billions of light-years away, but what’s causing them remains a mystery.

“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,” study co-author Avi Loeb, a theorist at the Harvard-Smithsonian Center for Astrophysics, said in a statement Thursday (March 9). “An artificial origin is worth contemplating and checking.” [5 Bold Claims of Alien Life]

One potential artificial origin, according to the new study, might be a gigantic radio transmitter built by intelligent aliens. So Loeb and lead author Manasvi Lingam, of Harvard University, investigated the feasibility of this possible explanation.

Scientists Searching For Alien Air Pollution

Scientists Searching For Alien Air Pollution

     Air pollution is clogging the skies of our planet. Now one scientist thinks Earth may be just one of many polluted worlds — and that searching for extraterrestrial smog may actually be a good way to search for alien intelligence.

“People refer to ‘little green men,’ but ETs that are detected by this method should not be labeled as green,” says Avi Loeb, an astronomer at Harvard University.

The idea of finding alien polluters may be a bit of a long shot, but Loeb says it’s possible.

Astronomers have been able to glimpse the atmospheres of planets outside our solar system for a while now. In 2018, NASA will launch the James Webb Space Telescope, which will be larger and better than ever at looking at extrasolar atmospheres.

“The idea would be that when a planet like the Earth is passing in front of its host star, a small fraction of the light from the star would pass through the atmosphere and show potentially evidence for these pollutants,” he says. . . .
