Mysterious Radio Wave Flashes follow Mathematical Pattern


Written by Jeanne Rife on 06 Apr 2015Mysterious Radio Wave Flashes follow Mathematical Pattern
Since 2007, telescopes have picked up almost a dozen of 'fast radio bursts', pulses that last for milliseconds. Astronomers have remained puzzled over these bursts seem to be hailing from billions of lights years away.

They wanted to know from how far they could be coming from. Now, it has been found that the burst appear to follow a mathematical pattern. A group of researchers working on this puzzle took benefit of a simple formula, which is, higher frequency radio waves face less interruption as they traverse space.

Telescopes detect them earlier than lower frequency waves. The researchers said that the time delay between higher and lower frequency radio waves for the same pulse event could be used to find out the distance that the waves have traveled.


The researchers calculated the dispersion distance from each of 10 fast radio bursts. After calculating, they found that each distance is integer multiple of a number- 187.5. When the researchers plotted a graph then the points formed had a striking pattern.

The resaerchers have claimed that there is a 5 in 10,000 probability that the line-up is coincidence. If the pattern is real then it is very hard to explain.

If the pattern is real then it could either be some strange celestial physics going on, or the bursts are artificial produced by human or alien technology.
Most lately, the fast radio bursts were detected in 2014, when the Parkes Telescope in New South Wales, caught a burst in action for the first time.

Till now, it is not known what causes them. But seeing the brevity of the bursts, it can be said that their source had to be small. Also, they seem to be coming from far outside the galaxy.

*What if* those bursts were a last call / SOS from a civilization facing a catastrophic event?.............

All they could hope for would be a more advanced civilization hearing, decoding and responding in a peaceful manner, in time to offer assistance .

"Far outside the galaxy" sums it up. If these signals were produced by intelligent beings they are now long extinct or have evolved to a higher plane where they no longer need radio waves to communicate. Nothing we can do except wonder and complete the studies.

I think it'd be awesome if these radio astronomers were able to decipher any pattern in the signals. If they are routine bursts right now, all 187.5 in dispersion distance, maybe it could be something like the klaxon that precedes an emergency broadcast message.

On the other hand, they say there is a 5 in 10,000 chance that the line-up is coincidence. Those odds are not astronomical at this point and given that we're talking about somewhere outside of our galaxy where there are billions of other galaxies, each with billions of stars, it could very well be a chance occurrence.

Regardless, I hope we stay tuned to this channel to receive further signals.

I think math permeates all existence. Space, life, whatever.

I think there is a Unified Theory although it may be so complex we may never find it.

Who would have thought there was a constant mathmatical ration between the size of a galaxy and the size of the black hole at the center, IN ALL UNIVERSES?

Ahh, someone who believes in the Infinite Universe.

Could Fast Radio Bursts Be Powering Alien Probes?
Release No.:
2017-09
For Release:
Thursday, March 9, 2017 - 11:00am

The search for extraterrestrial intelligence has looked for many different signs of alien life, from radio broadcasts to laser flashes, without success. However, newly published research suggests that mysterious phenomena called fast radio bursts could be evidence of advanced alien technology. Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies.

"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," said theorist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. "An artificial origin is worth contemplating and checking."

As the name implies, fast radio bursts are millisecond-long flashes of radio emission. First discovered in 2007, fewer than two dozen have been detected by gigantic radio telescopes like the Parkes Observatory in Australia or the Arecibo Observatory in Puerto Rico. They are inferred to originate from distant galaxies, billions of light-years away.

Loeb and his co-author Manasvi Lingam (Harvard University) examined the feasibility of creating a radio transmitter strong enough for it to be detectable across such immense distances. They found that, if the transmitter were solar powered, the sunlight falling on an area of a planet twice the size of the Earth would be enough to generate the needed energy. Such a vast construction project is well beyond our technology, but within the realm of possibility according to the laws of physics.

Lingam and Loeb also considered whether such a transmitter would be viable from an engineering perspective, or whether the tremendous energies involved would melt any underlying structure. Again, they found that a water-cooled device twice the size of Earth could withstand the heat.

They then asked, why build such an instrument in the first place? They argue that the most plausible use of such power is driving interstellar light sails. The amount of power involved would be sufficient to push a payload of a million tons, or about 20 times the largest cruise ships on Earth.

"That's big enough to carry living passengers across interstellar or even intergalactic distances," added Lingam.

To power a light sail, the transmitter would need to focus a beam on it continuously. Observers on Earth would see a brief flash because the sail and its host planet, star and galaxy are all moving relative to us. As a result, the beam sweeps across the sky and only points in our direction for a moment. Repeated appearances of the beam, which were observed but cannot be explained by cataclysmic astrophysical events, might provide important clues about its artificial origin.

Loeb admits that this work is speculative. When asked whether he really believes that any fast radio bursts are due to aliens, he replied, "Science isn't a matter of belief, it's a matter of evidence. Deciding what’s likely ahead of time limits the possibilities. It's worth putting ideas out there and letting the data be the judge.”

The paper reporting this work has been accepted for publication in the Astrophysical Journal Letters and is available online.

Headquartered in Cambridge, Mass., the Harvard-Smithsonian Center for Astrophysics (CfA) is a joint collaboration between the Smithsonian Astrophysical Observatory and the Harvard College Observatory. CfA scientists, organized into six research divisions, study the origin, evolution and ultimate fate of the universe.

It seems to me the most likely signature of an advanced alien species is
extreme miniaturization , not a transmitter ''twice the size of earth'' .
