    Repeating fast radio burst waves has never been discovered until mid last year.

    Makes me wonder if we are going to attempt to transmit a signal back the same direction that these 11 signals were detected from.

    Bump:

    1 year later and scientists have a really speculative but pretty interesting theory:

    Fast Radio Bursts could be evidence of advanced alien technology. It's worth putting ideas out there and letting the data be the judge.


    Specifically, these bursts might be leakage from planet-sized transmitters powering interstellar probes in distant galaxies.

    If the transmitter were solar powered and water-cooled, the sunlight falling on an area of a planet twice the size of the Earth would be enough to generate the energy sufficient to push a payload of a million tons, ~ 20 times the largest cruise ships on Earth, across interstellar or even intergalactic distances.

    Alternative article by Washington Post and video from SPACE.com



    What if ... such advanced extraterrestrial civilizations exist. :cool: And FRBs, GRBs, supernovae and even black holes are associated with their activity. Yeah it's implausible but physics kinda permits it

    Why solar powered? Makes more sense to have a fusion powered satellite in non-planer orbit perpetually targeting the craft. It would never really miss its target either. I'm with the skeptic in the article. It is a logical explanation for what was observed but it goes to the bottom of the drawer.

    Much more likely that the source of these emissions are from a young neutron star (pulsar) or highly magnetized neutron star (magnetar).

    Me thinks the astrophysicists have a full knowledge of what a radio signal from either of those phenomena would look like, and have thus ruled them out as being a possible source(s). In other words they've likely seen enough pulsars and magnetars(and/or other potential natural radio emission sources) to know the difference(between those and potential intelligence derived signals). They'd be pretty piss poor astrophysicists if they didn't. ;)

    but at the end they all try to cover it up with what it could be coming from lol, just like the WOW single from 1977

    An article published on March 9th at Science Daily states:

    And continues to state:

    https://www.sciencedaily.com/releases/2017/03/170309120419.htm

    Even though theorist Avi Loeb says "we haven't identified a possible natural source with any confidence" doesn't mean that a natural source of a star system billions of light years away can be counted out.

    Molonglo telescope has a huge collecting area (18000 m²) and a large field of view (eight square degrees on the sky), which makes it excellent for hunting for fast radio bursts. Scientists confirmed that FRBs that astronomers have hunted for 10 years really do come from outer space.

    Millisecond-duration intense pulses of radio light are ~ a billion times more luminous than anything we have ever seen in our own Milky Way galaxy.

    ^ Science is not about faith or beliefs. It's about theory and observations. Nature of FRBs is unknown.
    Whether they're astronomical phenomena or signals from advanced civilization remains to be seen. At least we know that they come from other galaxies.
    Trillions of galaxies with quintillion stars are there. I don't see why there shouldn't be any form of life or even intelligence out there.

    What if those signals are our own shifted from a black hole and bent in/through time :pimp:

    Leave it to scientists to write the unreadable... this is from a link in the original article...

    Fast radio bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances1, 2, 3, 4, 5, 6, 7, 8. Previous follow-up observations have failed to find additional bursts at the same dispersion measure (that is, the integrated column density of free electrons between source and telescope) and sky position as the original detections9. The apparent non-repeating nature of these bursts has led to the suggestion that they originate in cataclysmic events10. Here we report observations of ten additional bursts from the direction of the fast radio burst FRB 121102. These bursts have dispersion measures and sky positions consistent with the original burst4. This unambiguously identifies FRB 121102 as repeating and demonstrates that its source survives the energetic events that cause the bursts. Additionally, the bursts from FRB 121102 show a wide range of spectral shapes that appear to be predominantly intrinsic to the source and which vary on timescales of minutes or less. Although there may be multiple physical origins for the population of fast radio bursts, these repeat bursts with high dispersion measure and variable spectra specifically seen from the direction of FRB 121102 support an origin in a young, highly magnetized, extragalactic neutron star11, 12.

    Actually, a lot of what you say is a belief.
    The fact that you put this much into a 'theory' is a leap of faith. I almost said Quantum Leap of faith, but Darwin's Theory is often taught as if it were proven fact.

    No it's not belief. Science is always changing. What is fact today maybe wrong tomorrow. It's just approximation. Einstein showed that Newtonian mechanics can't account for very high velocities and hence general relativity is needed. General relativity and quantum theory are incomplete too so there should be something more fundamental than that and so on. Science will never stop and that makes it cool.

    Hashtag unpopular opinion, but... for most people, "Science" IS a religion. The priests wear ceremonial robes called lab coats, which signal their divine knowledge, and that you can trust what they say because "science." The religious texts are science journals and school textbooks. The archbishops and popes are people like Bill Nye and Neil deGrasse Tyson.
    I'm not saying science IS a religion, I'm saying that many people use it like one.
    Anytime you adopt a rigid, unchangeable dogma, and take what the leader says on faith, (and let's be honest, none of us here have likely seen ANY real evidence for the myriad theories we ascribe to, with our own eyes... so it IS faith) then what you have is not science. It's religion. And some people will fight to the death over the definition of a "theory." And we've changed the meaning of that word to mean "fact" over the past decade.
    Real scientists know that science is ever-changing, and nothing is set in stone. But the vast majority of the public who are on the "science" side of things tend to use it just like religious people use religion. There's really no difference.

    Like Black Holes, many talk about them as if it has been established as to what they actually are.

    The astounding misunderstanding of science in here depresses me.


    It could be that vast insurmountable distance thing we call "space"

    Also the earth is 4.53 billion years old, not an "arbitrary number of zeros" years old.

    Difference being I as an aerospace engineer tell you the plane can fly and i show you that in practice. The religious priest tells you people can walk on water, burn in hell, get 70 virgins etc with lack of any proof.

    We have proven that something is happening because there are visual sightings (usually multiple witnesses that have never met each other) confirmed with RADAR, SONAR, and/or physical damage to the surroundings (broken branches, residue left behind, and so on). Here's an example. Unfortunately, we know virtually nothing beyond that.


    Back on topic, neutron star seems plausible to me especially if the more they search for them, the more they find.

    Yes, but as an aerospace engineer, you likely haven't ever seen a Higgs-Boson particle. And yet you likely take it on faith that the scientists responsible for discovering it actually did so. That's all I'm saying. I'm not trying to invalidate science at all, I'm trying to invalidate PEOPLE who use it like a religion, and adopt unchangeable dogma instead of asking questions and discovering for oneself, as a scientist would.

    No while i haven't seen it with my own eyes there are experiments, papers in peer reviewed journals and data confirming that statement available. In science you have models that are valid within certain constrains and for all intents and purposes can be proven within certain boundary conditions. Unfortunately we haven't found a general physics model that encapsulates all natural phenomena but as gravity was not defined before the 17th century, or people thought no material can withstand the effects of breaking the sound barrier before WW2 just because we do not have understanding of how things work does not mean they are not possible. There are theories and hypothesis that are put in place and as technology advances they are confirmed or disproved.
