Since the discovery of these flashes in 2007, we have only detected a handful of them.
These flashes are called Fast Radio Bursts (FRBs), they are an intense flash of energy that last about a millisecond, and we have no clue what they are.
A group of well respected scientists at Harvard have made a serious claim they could originate from an artifical device made by aliens. They added it could feasibly be leaked energy from an alien transmitter that is used to send alien craft on missions.
Professor Avi Loeb, from Harvard centre for astrophysics said:
“Fast Radio Bursts are extremely bright given their short duration and origin at great distances, and we haven’t identified a possible natural source with any confidence.”
“An artifical origin is worth contemplating and checking.”
The technology required to make these energy flashes would would be centuries away for mankind. Solor panels twice as big as the earth would be required to power it.
The concept is mind blowing, but the fact we have no evidence of energy being made on this scale by any natural cataclysmic event means we have a major discovery waiting.
Could this discovery be extraterrestrial or just a natural phenomenon? Both are very exciting!
