Scientists Find More Mysterious Repeater Signals From Deep Space
Another set of mysterious “fast radio bursts” (FRBs) from a distant galaxy were recorded by astronomers at the Canadian Hydrogen Intensity Mapping Experiment (CHIME) in British Columbia. Scientists are still unsure of the source of these strange bursts, though one potential explanation posits that they may be the product of an advanced alien civilization.
The latest bursts are the first recorded from this source since it was accidentally discovered in 2007. Astronomers remain baffled by this latest recording, which detailed signals at a significantly lower frequency than their first discovery. Initial frequencies clocked in at 1,400 megahertz, but the latest bursts came in at around 400 MHz; the lowest possible frequency their instruments could detect.
Is this potential alien civilization sending signals at varying ranges to increase its chances of being heard? If so, it seems we’re picking up all of them.
Though they were first discovered in 2007, speculation around the FRBs’ origin didn’t captivate headlines as much as it did in 2017 when Professor Avi Loeb of the Harvard-Smithsonian Center for Astrophysics published a paper suggesting the alien possibility.
“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,” Loeb said. “An artificial origin is worth contemplating and checking.”
There are two competing theories on the extraterrestrial potential; the first being that a civilization is transmitting their calling card in hopes of contacting another civilization like ourselves. The other possibility is that the bursts are propelling the sails of alien probes in deep space – a type of technology the Breakthrough Initiative is currently attempting to develop.
Astronomers noticed that whatever the source of these waves may be, it’s scattering the radio bursts – meaning it must be a massive object with “special characteristics.”
“That could mean in some sort of dense clump like a supernova remnant or near the central black hole in a galaxy,” said Dr Cherry Ng, a team member in the study from the University of Toronto. “But it has to be in some special place to give us all the scattering that we see.”
In the event that these bursts are coming from an alien megastructure, their source would likely have to be at least the size of a planet, unless they’re being emitted by some technology we can’t yet fathom. This would surely put the civilization beyond level one on the Kardashev scale, a level in which they have been able to harness all the energy of their home planet. We, on the other hand, have yet to reach such advancement.
Could this latest discovery mean we’re on the precipice of making contact with an advanced extraterrestrial civilization? It might be time to start building an intergalactic radio broadcaster of our own…
Deciphering The Order of the Dolphin; A Plan for Alien Contact
Consider the remarkable characteristics of the brains of bottlenose dolphins, and how similar they are to our brains. While their brain-to-body-weight ratio is second only to humans, at 1600 vs. 1300 grams, their brains are more substantial than ours. This is why John C. Lilly, Frank Drake, Melvin Calvin, Carl Sagan, and ten other scientists formed The Order of the Dolphins in 1961.
With Lilly at the helm, this brilliant group of dolphin-lovers and E.T. enthusiasts would soon form the group, S.E.T.I. (Search for Extraterrestrial Intelligence). Their mission, which continues today, is to discover how to find, attract, and talk to aliens.
Believing that dolphins are as sentient and intelligent as humans, S.E.T.I. wanted to learn the dolphin language, and teach English to them. Doing so, they suspected these profound creatures would eventually prepare us for when it came time to decipher alien languages, and communicate with extraterrestrials. According to Lilly, through “dolphinese,” dolphins would one day hold a seat at the U.N.
How Dolphins Communicate; Compelling Attributes Of The Bottlenose Dolphin
It’s not just the brain weight and related ratios that make this premise so exciting. Dolphins have a very complex neocortex, densely packed with billions of neurons, almost perfectly aligned with humans. This tells us that dolphins are adept at problem-solving, emoting, social cognition, perception, and the theory of mind, which includes having beliefs, desires, and intentions, with the ability to sense what others are thinking. Also, these beautiful creatures have proven that they grow cultural traditions, which they pass from generation to generation.
Dolphins can understand sentences constructed with elaborate gestures, and they’re adept at pinging underwater keyboards to communicate their desires to humans. Dolphins also have the unique, human-like ability to recognize themselves in mirrors. By all accounts, dolphins are self-aware and should be considered sentient beings. There are 40 species of dolphins.
