About Those Fast Radio Bursts From Space ...
Fast radio bursts from space may be an extraterrestrial calling card, or maybe a form of distress call, according to Professor Avi Loeg of the Harvard-Smithsonian Center for Astrophysics (so not some lugnut writing for certain weekly tabloids).
These fast radio burst have been known for a while, but remain largely unexplained, which is where Prof Leob comes in to theorize:
"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"
He reasons that an artificial source may be at work, possibly a giant signaling devices of some sort, which although massively powerful, would be theoretically possible to build and operate.
Why? Well that's not something the professor and his team speculate on - they are just trying to fit the facts to a possible theory.
