Dr John Ball, an astronomer at the Massachusetts Institute of Technology (MIT), thinks aliens could have been trying to communicate with us for years.
Dr Ball wrote a research piece called "Gamma Ray Bursts (GRBs) that claims the two-millisecond bursts contain quintillion bits of information. He wrote:
“GRBs may be signals transmitted by extraterrestrial civilisations. The temporal shape of the bursts at the transmitter is probably a simple pulse and the complex shapes we see are due to distortions en route primarily gravitational lensing. So far as we know, gamma rays [are] the only feasible way to send large quantities of information over intergalactic distances"
Now we're not scientists, but what he seems to be saying is that these rays are possibly the only way to send huge messages over long distances so aliens might well have been trying to talk to us through them. The gamma bursts could carry 1,000,000,000,000,000,000 (1×10 to the power of 18) bits of information and Ball says “this is comparable to the estimated total information content of Earth’s biosystem — genes and memes and including all libraries and computer media.”
Other scientists have suggested the GRBs are sent out when a massive star dies and implodes to form a new black hole but Doctor Ball thinks they could be spores that are sent out and multiply only to land and breed… which would be a real mind trip. Alien spores all through the galaxy – how could that end badly?
