From what this mystery sound is, to what it
could mean in general and for all of mankind! Join me as we explore the Mysterious Fast
Radio Burst (FRB) signal from another galaxy that Is Repeating every 16 days! In space, no one can hear you scream, right? Well that may or not be true (Mythbusters
actually tested this as a matter of fact) but the real truth is that in space there
are TONS of sounds for us to listen to and observe and potentially understand. We have recorded the sounds of the sun, of
various planets, and occasionally, outer space sends us a signal that we call a Fast Radio
Burst or FRB that rings out and we have to discover what it is and what caused it to
be formed. “FRBs are hugely energetic flares of radiation
in the radio spectrum that last just a few milliseconds at most. In that timeframe, they can discharge as much
power as hundreds of millions of Suns.” This kind of science is very intriguing and
very important because of how it helps us understand space as a whole. But, the catch is this, these FRBs are meant
to be very fast, and very singular in their message. Meaning that the “message” that they deliver
throughout the stars is not repeated. It happens, and then it’s gone. That’s what makes it so much of a mystery
at times because we have to figure out what series of events led to that sound. Occasionally, there will be a signal that
is found that sometimes repeats, but never is it regular, it’s just never happened…until…
…for the first time, astronomers have found a fast radio burst (FRB) that repeats on a
regular cycle. Every 16.35 days, the signal named FRB 180916.J0158+65
follows a similar pattern. For four days, it will spit out a burst or
two every hour. Then it falls silent for 12 days. Then the whole thing repeats. Astronomers with the Canadian Hydrogen Intensity
Mapping Experiment (CHIME) Collaboration in Canada observed this cycle for a total of
409 days. We don’t yet know what it means; but it could
be another piece in the complicated conundrum of FRBs. Complicated indeed, because certainly this
has never happened before. Last year, the CHIME collaboration announced
they had detected a whopping eight new repeating fast radio bursts, bringing the then-total
of repeaters to 10 out of over 150 FRB sources. And as of now, that’s been upped to 11. But even then, 11 out of 150 of these signals
being repeated in some way, and then one and only one being repeated regularly and in a
real timetable? That’s just weird, and it’s got a lot of people
scratching their heads as to why this can happen, and how it happens. But that’s the thing though, because this
particular signal is a repeater that has a timeline, that means it can be further studied:
“The discovery of a 16.35-day periodicity in a repeating FRB source is an important
clue to the nature of this object,” the researchers wrote in their paper. Think about it, if it is repeating like clockwork,
that means there’s a series of events going on that is causing the signal to happen at
a regular frequency. This could be the work of galactic objects,
or something going on with a nearby star, there are some who even speculate that black
holes could be a major player in all of this. But it’s still a bit unclear. However, there are a few things working in
the favor of those who are trying to figure this out. FRB 180916.J0158+65 is one of the handful
of FRBs that have been traced back to a galaxy. It’s on the outskirts of a spiral galaxy 500
million light-years away, in a star-forming region. This means a supermassive black hole is unlikely,
but a stellar-mass black hole is possible. Black Holes are still very much a mystery
to us in regards to their power (which is massive and can destroy about everything)
their cores, and all the effects they have on objects. Given that things about them are still being
learned it’s possible that this signal is nothing more than a byproduct of its natural
life. Or even the potential nearby stars natural
lives: “The single constraint on the orbital period
still allows several orders of magnitude range in companion mass amongst known stellar-mass
compact object binaries: from so-called ‘black widow’ binary systems, consisting of a low-mass
star and a powerful millisecond pulsar whose wind ablates the companion (albeit typically
with few-hour orbital periods), to massive O/B stars with highly eccentric companion
pulsar orbits,” the researchers wrote. But, that doesn’t mean the opposite couldn’t
also be true… Before we continue diving into all of this
signal and other business, be sure to like the video and subscribe to the channel! That way you don’t miss any of our weekly
videos! This is the major problem with FRBs, there’s
just too much we don’t know about where they came from, what they are doing, and why they
are doing things at the rate they are or even the rate they aren’t going on. What makes some of them repeat and some of
them not? What really is the difference between all
the FRBs, or is there any at all. Well, we might have a small clue on that front,
but it may not be what you expect it to be. Do you remember that 11th repeater I mentioned
earlier? It was found coming from an FRB astronomers
had thought was a one-off; its repeats were simply too faint for the equipment that had
initially been used to look for them. Which believe it or not is a common problem
with our researching the stars, as we sometimes have the means to look at the stars, or observe
them and other objects in certain ways, but rarely can we do a deep dive like many want
to. Getting back on track, this suggests that
many more FRBs could be repeating, but outside our detection range. And the fact that FRB 180916.J0158+65 seemed
more or less the same as other FRBs could mean that other repeating FRBs are also on
a cycle – we just haven’t detected those cycles yet. “Future observations, both intensity and polarimetric,
and at all wavebands, could distinguish among models and are strongly encouraged,” the researchers
wrote, “as are searches for periodicities in other repeaters, to see if the phenomenon
is generic.” And that’s what scientists are going to do! They’re going to keep looking at this signal,
and more to see what else pops up, and if any clues arise about what it truly might
be, whether it be something generic, something special, or something else in between. So what does this say about our universe as
a whole? Well, simply put, there are still LOTS of
things about our universe that we don’t know, don’t understand, and are unlikely to understand
at this point in time, and likely in the immediate future. After all, with many of these FRBs being light
years upon light years away, we’re already playing a game of catch-up in regards to how
we’re finding out about these signals, and trying to determine what they are all about. Don’t forget, FRB 180916.J0158+65 had to be
studied for hundreds of days to determine that it was a real repeating signal, and that
was just ONE true fact that we found out about it, everything else that surrounds it? Not so much. Now I’m sure some of you are stating the following,
“Well since it’s repeatable, doesn’t that mean that it’s something non-natural? You know, that this comes from aliens?” Usually this would be the point where someone
would mock you because of that notion, but not here. The alien question is a sound one, and it’s
one that many have put to the test when it came to these many FRBS, and especially FRB
180916.J0158+65. After all, it’s very true that with the repeatable
nature of this signal that it would seem to indicate that it would be something constructed
and repeated by someone or something. Here’s the thing though, while they were researching
these signals and plotting them out, they noticed that every single signal was different. Which does not discount alien life for the
record, but the fact that the signals have no similarities between them at all, and yet
all feel the same in their length (outside of the signal we’re focusing on today) seem
to indicate that these are indeed natural occurrences. After all, if this was an alien signal, why
would it be going on for only a few milliseconds? Not to mention, why wouldn’t it repeat? Only 10 of these FRB signals have ever repeated,
but it wasn’t in a pattern-like setting in the way that FRB 180916.J0158+65 did. So for an alien species to do something like
that would either be very primitive, or very dumb. Or, of course, it could be an advanced way
of communicating that we don’t understand, but at present, it doesn’t seem that way. As for FRB 180916.J0158+65, it would be fair
to say that its repeating pattern would indicate a signal from an advanced society that can
send signals into space. But that raises the question of, “Why only
once every 16 days?” While that is a pattern, that doesn’t seem
to be one that would be done by a society. Sure, it could be that because of their place
in the galaxy they’re in that we’re not receiving all the signals, or that the ones that reach
us are the ones that are made every 16 days for various reasons. But based on the observations of the signal,
they seem too basic to be alien communications. To be clear, this does NOT prove that aliens
don’t exist, it’s just that when it comes to this particular anomaly in space it doesn’t
add up to it being aliens. At least…not this time. Which brings us back to the belief that it’s
a natural sequence of objects that are causing these events to happen. Notice that I said the word “belief” and not
“theory”, because when it comes to these FRBs, we honestly don’t have a lot of theories that
match up with the signals we’re getting in space. Even FRB 180916.J0158+65 has a lack of theories
surrounding it because there’s just not a lot to go. The few things we can guess about it in terms
of the “natural events” that cause it to make these radio signals is that something is blocking
it for sixteen days, and then it opens up for a period of time before being blocked
again for another 16 some odd days. Does this sound like something familiar to
you? It should, because it sounds like an orbit. If the signal is say coming from a planet
for one reason or another (again, not aliens, not this time) and its orbit around the star
or stars that it’s around makes it “blocked out” for a period of 16 days and then able
to get free enough to make the signals, that would give us a lot of clues as to why the
signals only reach out during those points. Including possibly telling us why the stars
are affecting that planet in such a way. Or, if this is another celestial object like
a star causing the signal, like a neutron star, a pulsar, or a black hole, if we can
single out why it only happens in certain bursts, or even why it’s happening at all. But even with the longer and repeating frequencies,
if it doesn’t happen enough or in a way that we can examine them, we’re kind of helpless
in terms of trying to figure out what is going on with them and why they are happening at
all. Perhaps the biggest mystery of all of these
is why they happen in scattered parts of the universe and why they don’t last very long. What could make this happen all over, yet
not be the same as the others, and still only last a short time? No one really has an answer to this. Which brings us to an interesting point that
no one can technically dispute. What if the reason we don’t know what these
signals really are, or where they came from, is because they’re from something in the universe
that we don’t fully understand yet? I know this may seem like a copout answer,
but you need to realize that when it comes to this universe of ours we know a LOT less
than we think. What’s more, we’ve proven time and time again
that every time we think we know something, it’s only because we’ve forced ourselves to
understand it. A great example is the recent discoveries
of more moons on Jupiter and Saturn. How in the heck did we miss those when they’re
in our own solar system? It’s because we can’t keep an eye on space
all the time, and that means…there’s things out there we don’t fully get. A great example of this is neutron stars,
or pulsars, or even black holes! At one point in time scientists didn’t know
or understand how these things worked, or what they even were! And it took time and effort and energy and
research to figure it all out. If it took them that long to figure out that
which is “common knowledge” now, how long might it take to figure out these radio signals? The universe is vast, and it doesn’t give
up answers that easily, which is why so many people are trying to solve its mysteries. And this just the latest one of the bunch. Thanks for watching everyone! What do you think about these mysterious fast
radio bursts and the new one that has a repeating pattern? Do you think that the mystery of what they
are and how they’re created will be solved soon? Or do you think it’ll take a while before
we figure it out? Let me know in the comments below, be sure

  1. Hmm !!! Scientists are suggesting that These FRBs are the result of the Interaction between the OB Type Stars Solar Winds and the Magnetic Fields of Rotational Neutron Stars !!! Thank you, Bro !!!

  2. Friendly suggestion: Next time you should state that, for the sake of brevity, FRB 180916.J0158+65 is going to be referred to by its shorter nickname "Tony" for the duration of the video.

    For example: "Tony is one of the handful of FRBs that have been traced back to a galaxy."

  3. Whatever point you are trying to make by repeating the name of the FRB is extremely annoying and made me lose interest in your video five minutes into it. And.. I was very interested in the subject, but no thanks.

  4. Other big radiotelescopes doing follow up observations of the source during its active phase.

    http://www.astronomerstelegram.org/?read=13492

    And reported – "During our observations, no burst was detected.."

    What does it mean when one telescope repeatedly observes the signal while it is not seen at other points of the Globe?

  5. 11:54 Let me anwer you quastion "why its not last long" – You see, the distance is very far away, the rotation of bust is maybe not so fast but in a distance, the cirkel whice the signal cirkulate, is very BIG, therefor we get only the signal very short of time.
