10 Unsettling Astronomical Incidents and Phenomena

By | November 16, 2019

The universe is a strange place by its very
nature. Mysterious questions abound over dark matter,
dark energy, how it all came to be and so on. But at the same time, as our astronomical
instrumentation has improved, in modern times we have been able to study the universe in
unprecedented detail. As that process has unfolded, the universe
has rewarded us with both understanding, but also new mysteries, many of which have not
been solved. In the course of making this channel, I’ve
run across and covered many such astronomical mysteries, some of them now solved, some of
them not. But there has always been a core group that
offer possibilities so weird, that they continue to baffle scientists to this day. So here are 10 Unsettling Astronomical Incidents
and Phenomena. Number 10 The Nature of Pulsars When pulsars were first discovered in the
1960’s the possibility that they were alien beacons had to be seriously considered after
it was shown that they were not a product of earth interference. They were, after all, highly unnatural looking
pulses of electromagnetic radiation that repeated with such regularity that some of them rivaled
the accuracy of atomic clocks. In the years since, we’ve learned that they
are just an unusual case of nature emitting a regular signal by way of a rapidly rotating
neutron star. This would seemingly lay the idea of alien
involvement with pulsars to rest. Except, it actually doesn’t. In 2017, Clement Vidal authored a paper that
reopened the question of an alien technological origin for pulars, or at least a certain class
of them that could have been natural objects tweaked by aliens for communications. He pointed out that there were five reasons
that aliens were originally taken off the table as an explanation. The first was the truly titanic amounts of
energy involved, it seemed unlikely to some that a civilization would use that kind of
energy. Trouble is, we’ve never seen an alien civilization
and really have no idea what they would be capable of energy wise, and we do still talk
about galaxy spanning Kardashev type III civilizations that would command far more energy than a
pulsar. The other four reasons are equally problematic. One was that they are not unique. In other words, how likely would it be that
two seperate civilizations would broadcast the same way at similar frequencies. Well, our earth civilizations do that, and
SETI does spend a lot of time looking for aliens at the frequency 1420 Mhz because there
are inherent scientific advantages to do so that alien scientists would also know about. Perhaps that could be the case with pulsars. Another reason was that pulsars generally
do not emanate from planetary systems, but who says aliens have to stick to a planet? Also, they are not narrowband, kicking out
broadband transmissions wastes energy and technology generally sticks to narrowband
as a result. But if pulsars started out as natural objects,
that are being tweaked for communications by exocivilizations, then broadband may just
be a natural leftover artifact. But the fifth argument is the most solid. We have perfectly good natural explanations
for pulsars that fit the bill. There really isn’t a reason or need to evoke
aliens when something appears explained and natural. But that doesn’t eliminate the pesky possibility
that pulsars could be tweaked by an exocivilization as a natural carrier for communications and
that, maybe, we should look for that, especially in light that some of them are extremely accurate
in their pulses, to the point that they could be used for something like a navigational
beacon. That near absolute regularity present in some
pulsars does still look a bit odd, decades after they were first detected. Number 9 Fast Radio Bursts This particular phenomenon is a relatively
new one, having only been discovered in 2007. They come as a very quick bursts of radio
waves that arrive in such a way that scientists know that while extremely powerful, they must
come from very small sources that are very likely outside our galaxy, limiting what could
be causing them. Further limiting what they might be is that
at least one has been seen to repeat, seemingly ruling out any sort of cataclysmic event,
such as a black hole merger. Most hypotheses currently on the table involve
neutron stars or magnetars in some sort of odd situation, but it’s also hypothetically
possible that they could be of alien origin. In 2017, Manasvi Lingham and Abraham Loeb
released a paper, link below, explaining that it’s possible that the origin of at least
some of them could be leakage from alien light sails, because the frequencies at which FRBs
are detected happen to also be optimum frequencies for use with light sails. More, given that the FRBs have been shown
to originate from very small sources, they point out that the emitter for a light sail
would need to be about twice the diameter of Earth, well within the constraints on what
could be producing FRBs. Number 8 The Dyson Sphere Candidates Sometimes ideas within the realm of futurism
can be so speculative that, if realized, are probably going to prove impractical. One such concept is the Dyson Sphere, though
it should more accurately be called a Stapledon Sphere, after the sci fi author that envisioned
them in the 1930’s, as opposed to Dyson’s actual vision of a swarm of energy collectors. To actually encase a star within a solid shell
would be a megastructure undertaking of truly titanic proportions that would involve things
like completely disassembling planets for raw materials. And, it’s not entirely clear how such a
thing would be engineered, constructed and maintained. Surprisingly however, out of all the hypothetical
alien megastructures that we have yet envisioned, the Dyson Sphere remains the only one for
which we have detected candidates, though they probably aren’t very good ones and
are likely really due to natural phenomena. The detections stem from a search of infrared
data from the IRAS satellite done by scientists at FermiLab. The idea is that Dyson Spheres absorbing energy
from their star would re-emit that energy in the infrared in a specific, detectable
way. They found 17 candidates that fit, though
they were very ambiguous and probably have natural explanations, though efforts to figure
out what they are are ongoing, and another project to search for them using the GAIA
spacecraft has already yielded a further two eyebrow raisers, TYC 7169-1532-1 and TYC 6111-1162-1
though again they are really ambiguous. Nothing definitive, but in coming years if
civilizations do indeed encase their stars in Dyson Spheres, it seems likely we’ll
spot it. Number 7 The Phantom Planet Unlike most of the phenomena on this list,
this one could well be explained within the next few years, as several groups of scientists
are actively looking for it. The motion of objects in the outer solar system
is peculiar, as though they were disturbed by a large object in the outer solar system. In fact, yet another object showing orbital
peculiarities consistent with this was found recently, bolstering the case that another
planet exists in this solar system much further out than the orbit of Neptune. One possibility is that it’s the solar system’s
missing super earth. Our star system is unusual because we lack
a super earth, seemingly one of the more common types of planets in the Milky Way. This hypothetical planet may have formed closer
into the solar system, but might have been pushed out early in the solar system’s history. Another possibility is that it may not be
from this solar system at all, and may be a captured object the sun acquired at some
point in its history, in which case it would truly be an alien interloper in our star system,
and would offer a chance at studying an actual former exoplanet that formed somewhere else. While it’s not universally accepted that
Planet 9 must be out there, there is also an arguement that the data is skewed and it
may not exist at all, whatever the case, as hints of this phantom planet’s existence
continue to surface, it seems very possible that within a few years we may well have another
known planet to explore. Number 6 TYC 8241 2652 This entry is truly bizarre because not only
is there no ready explanation for it having happened, but also no ready explanation for
how fast it happened. In 1983 the star TYC 8241 2652 was observed
in the infra-red to have a debris disk. That in itself is nothing unusual, dust disks
are a normal part of planetary formation, and indeed earth itself formed from one. And over time, a very long time in geologic
terms, these disks tend to clear out as stable planetary systems develop. When TYC 8241 2652 was observed in 2010, the
dust disk had completely disappeared, not in millions of years, but in the time since
a previous observation in 2008. Whatever caused the dust’s disappearance
did it under two years. Numerous natural explanations were suggested
for just how that could happen, only to fall flat and the cause for the disappearance remains
a mystery, and has been seen in no other star system with debris disks since. Number 5 234 Detections of Something Strange Occasionally, a scientific paper will come
out that’s seemingly worthy of attention and then instantly go into obscurity. That’s essentially what happened with a
paper by Ermanno Borra and E. Trottier in 2016. It related to an earlier paper by Borra where
he predicted that certain types of pulses could be produced by current technology and
be detected a thousand light years away, and vice versa. Borra then searched existing data for anything
that might look like those kinds of signals. He found 234 of them. Now, the media at the time sensationalized
the story and in some cases badly reported it as though aliens had been found. This was not the case, and the scientists
themselves made no claims that this was an actual detection of alien civilizations, merely
that that was a possibility and that further follow-up work should be done. And that’s where it sits today, but one
thing still stands out. Nearly all of the detections where coming
from stars of spectral types believed to be suitable for life. 1220-91-1
Number 4 The Wow! Signal This bizarre signal in some ways gets even
more bizarre as time goes on simply because an alien origin for it cannot be ruled out,
even though the signal was detected over four decades ago. In 1977 (check) astronomer Jerry Ehman using
the Big Ear radio telescope at the Ohio State University picked up a signal. This signal was noteworthy for several reasons. The first is that it was very close to 1420
Megahertz, which is the frequency at which hydrogen, the most common element in the universe,
emits radio waves. This frequency is of note to SETI scientists,
in fact it’s set aside and not broadcasted on specifically for this reason, because any
alien civilization that possesses science and radio transmitters would know of this
frequency. As a result, it might be a universal frequency
to broadcast a contact signal. The second is that the Wow! Signal was strong. Very strong, which is why Dr. Ehman famously
wrote wow on the printout. The third strange thing about this signal
is that it was narrowband, which is in itself very odd. Nature tends to emit radio signals broadband,
whereas technology tends towards narrowband. Another odd aspect of Wow is the fact that
it was a very brief signal, it was there and then it was not. That seems counterintuitive for a contact
signal, and it’s never been picked up since, despite plenty of attempts to do so. Perhaps the strangest aspect of Wow though
is that it keeps defying explanation. It’s never been shown to have been earth
interference, or a glitch in the equipment that picked it up. To this day, potential explanations continue
to be put on the table, only to be shot down. This happened most recently with the hypothesis
that Wow! might have been due to emissions originating from comets, and this was widely
reported in the press as a case closed explanation. What they didn’t report as widely is that
the comet hypothesis was shot down by the scientific community very quickly. If comets emitted that strongly at the hydrogen
line, radio astronomers would have noticed that by now and it should be easily observable. It’s not. So, to this day, the Wow signal remains unexplained. Number 3 Strange Signals While the Wow! Signal is the most famous of the unexplained
odd radio signals SETI astronomers have picked up, it is not unique. Other examples include a signal picked up
just once, and did not repeat, from the direction of the star TYC 1220-91-1. What’s notable about this signal is that
it appeared to originate from a nearby star that’s very similar to our sun, and potentially
habitable. It was also at a magic frequency mathematically
related to the 1420 megahertz hydrogen line. It was also narrowband, and was observed for
a full ten seconds. But most noteworthy was that the signal was
so strong, about ten times stronger than Wow!. But, since the signal didn’t repeat and
couldn’t be verified, it can’t ever be determined if it was simply earth interference. Other unverifiable signals include a 2015
signal from the star HD 164595, another very sun-like star, but this time with a verified
planet in orbit around it. But it never repeated, and it happened to
be in a military band, and it seems likely that there are satellites downlinking from
orbit that scientists may not be aware of. And then there was the signal SHGb02+14a,
which was weird even for a signal plausibly of alien origin. Firstly, unlike most, this signal repeated,
having been initially observed three different times. And, it was at the 1420 Megahertz frequency,
initially. But then it would drift. More, there didn’t seem to be any corresponding
star system to where the signal was coming from. And it was very weak, and if it originated
on a planet, that planet would have to have been rotating 40 times faster than earth. Number 2 KIC 8462852 Tabby’s Star In 2015 a star was found in the massive amount
of data collected by the Kepler spacecraft that was behaving like no other star previously
seen. It would experience dips in brightness of
up to 22 percent suggesting that something extremely massive was passing in front of
the star. Initially, it was uncertain as to what this
could be. A cloud of dust wasn’t a good fit because
star systems that have dust discs tend to emit infrared radiation brightly. No such radiation was found at KIC 8462852. The star’s main investigator, Dr. Tabetha
Boyajian, suggested that it could be cold comets blocking the light. But on further investigation, it was found
that the number of comets needed to produce the effect would have been implausible, hundreds
of thousands of them. More, another study found that exocomet signatures
in the Kepler light curve don’t fit what’s going at Tabby’s star. Given that natural explanation after natural
explanation were falling flat with this star, the idea that gigantic alien megastructures
could be blocking the light was starting to be considered. Now, even that doesn’t fit as later researched
showed that whatever was blocking the light, at least with the most recent dips measured
from the ground here on earth, was not opaque, and that dust in some bizarre juxtaposition
around the star was the cause. But there’s still the question of the missing
infra-red. To date, no one yet knows exactly what’s
going on at KIC 8462852. Number 1 Pryzybylski’s Star At the time when the KIC 8462852 story was
a media hit, it was often called the strangest star in the universe. And while it certainly was strange, this final
star on our list gives it a run for its money. The star is called Pryzybylski’s star after
the Polish-American astronomer that first studied it. The star is what’s known as a peculiar star,
a class of stars that are chemically unusual in some way when compared to other stars. But even then, this star stands apart because
it contains elements that really shouldn’t be there and are more at home in a laboratory
on earth than in nature. And it’s not just a handful of odd elements,
it’s a lot of them, in sufficient quantities to be detectable at great distance in the
star’s spectrum. Elements like praseodymium, ytterbium, technetium
and prometheum are present, the last only discovered through the activities of the Manhattan
project. Certainly odd, but stars can have odd elements
in them. But there’s more, the star is also anomalously
low in iron and nickel, abundant elements in the universe, but perhaps strangest of
all are the very short-lived actinide elements higher on the periodic table than uranium. Quite a few of these are present, and it’s
just weird, but one in particular raises an eyebrow. Plutonium. Plutonium is thought to be produced only in
minute quantities in nature, and only under specific circumstances. For this star to have it in abundance is a
mystery, though hypotheses have been put forth that you might be able to get to elements
higher than uranium if the star were bombarded by a neutron star, or some unknown nuclear
process within the star is creating them. But it’s worth mentioning that in 1966 Carl
Sagan and Iosef Shklovski hypothesized in their book “Intelligent Life in the Universe”
that one way for an alien civilization to announce its presence to others would be to
add plutonium to its star. Thanks for listening! I am futurist and science fiction author John

    A lot of these issue don't HAVE to be weird yet as they are stated here probably offer some of the best arguments to look OUTSIDE of the gravity-centric view of the universe for explanations that provide more sensible answers. Example: Why not explore the possibility of pulsars as relaxation oscillators (i.e: a simple electrical circuit creating a strobe effect) which would better explain some of the REALLY odd variations that have been observed within pulses of some of them (which the gravity-centric model has absolutely NO explanation for) not to mention the seemingly impossible rotating speeds that these pulsars are suppose to be exhibiting which the gravity-centric says is happening yet cannot reconcile with practical physics. Nothing the size of these stars can rotate faster than a dentists drill and maintain their coherence. When you start hitting weird explanations for phenom that is being observed – and you have to make even more weird explanations for WHY it's happening – it's time to check your bias and your assumptions about what you THINK you know.

    The fact that SETI (stupid excuse to investigate) hasn't received an alien signal doesn't surprise me. I highly doubt they ever will no matter how much money they waste trying. I used to think that we can't be the only intelligent beings in this ginormous universe, but my decade-long study of the creation/evolution debate has completely changed my mind. In my humble opinion the universe exists, among many other scientific facts, just to make evolutionists look stupid…

    Hey, how many evolutionists does it take to screw in a lightbulb? None. They just sit around waiting for it to happen by chance…

  17. Blake Lonsdale-Cook Post author

    The Plutonium Star seems like an alien K2 species in an interstellar war has built the largest weapon of mass destruction. Fission fusion bombs on Earth use a High Explosive to set off fissile nuclear super-criticality. The resulting nuclear explosion is powerful enough to fuse hydrogen ions, turning the fission bomb into a fission-fusion thermonuclear bomb.

    The supposed limit for this process is 7 tampers. Fission triggers a fusion reaction, which then triggers fission, which triggers another fusion layer, which triggers yet another fission tamper, which triggers a third fusion layer, and this repeats to the 7th fusion stage. By this time, the energy from the first nuclear fission has begun to be released in other forms than the initial gamma/neutron/x-ray burst of energy at super-criticality, and the force of that explosion disrupts the propogation of the explosion through further layers, should they have existed.

    Modern nuclear weapons on Earth use 1-2 fusion layers, and generate blasts over 1000x more powerful than the one that destroyed Hiroshima and Nagasaki. Russia tested a bomb that had a force of 50-57MT of TNT. That's over 1000x the force of both bombs combined. In fact, that about the same force as 2000 of the bomb dropped on Hiroshima and 1000 of the bomb dropped on Nagasaki combined. That would be about 52MT. Those "just" used fission, and had no fusion stage. Just adding a single fusion stage makes the explosion 500-1000x more powerful.

    So the idea an alien civilisation existed that built a fission-fusion bomb out of a STAR is disturbing in the least. What would a sufficiently large nuclear blast in a star do to that stars fusion process? Perhaps detonating a large enough blast inside a star could disrupt the stars light pressure long enough to get the star to implode under it's own gravity, then violently explode again due to the force of the collapse in a supernova, collapse it into a black hole or neutron star.

    Or they could simply just have detonated the star (although it happened in their past, the information won't reach us yet for us to find out, spacetime is weird like that) using the majority of the stars fusion material as part of the largest sentiently-designed nuclear explosion in the history of the human-observed universe.

    I can not Understand how some of the best minds in science believe in something so silly like a Dyson Sphere
    Or the Kardashev scale
    First off there are much easier ways for gathering energy than a Dyson Sphere
    Secondly Kardashev scale is silly because civilizations can go from a type 0 civilization to knowing all there is to know in a couple generations with quantum computing
    People believe that gaining knowledge will continue as it has in the past
    Not thinking for a moment that knowledge could experience exponential growth
    There where decades in the 20th century that more knowledge gained than the entire history of humans
    Both of these ideas show a total lack of understanding of how the progression of science will work
    It sounds good so people repeat this misnomer as matter of fact

    When watching the skies, and in that the stars and galaxies and such, people will sooner
    or later find possibilities that are highly unlikely and yet completely possible.
    The chances of anything occuring which is highly unlikely, increases with the number
    of stars observed and the time they are observed.
    If the number of stars observed reaches even millions, as a direct result,
    possibilities of observing something that only happens with a frequency of one in a million
    should be well within the realm of possibility.
    As the number of stars observed increases over time, even the most unlikely
    scenarios occur.
    There you have your peculiarities, and all you have to do see such exceptions in nature
    is to watch the stars, while watching them long enough will result in more 'apples on the head'.

  36. ZMacZ Furreh Post author

    08:43 Anything that can happen in the universe probably happens somewhere at any given time.

    With an unstable planetary body being rammed by a planet sized body foreign to the system, for instance,
    producing a very short lived cloud of debris.
    Given that such rammings can occur even though highly unlikely from near exact opposing
    trajectory planets, this may yet happen.
    If and when such a ramming occurs, the kinetics of most of the masses of both objects
    would cancel out mostly, leaving the dustcloud without sufficient speed to be an robit,
    and thus freefall into the star itself.
    Dependant on the amount of cancelation, with 100% being a true freefal towards the stars surface,
    and 1% being a freefall that still occurs but after many still possible decaying orbits,
    you see where I go with this.
    planetray objects collide, leaving dust clouds, and dependant on the amount of cancellation of
    kinetic energy within each, now 'one' mass, you have either still sufficient kinetic
    energy left for an orbit, or you have too much, leading to escape, or too little
    leading into a decay.

    The solution here that fits most (if not all the facts) is this.

    5:21 Dyson sphere's are an implausible myth.
    Why ? the fact that a true sphere would have to be partially kept in position,
    by generating a continuous local gravity to keep the top and bottom from
    falling into the sub, unsustainable by any even remotely plausible physical building techniques.
    The amount of energy expended on keeping the top and bottom in place using such
    artificial garvity would exceed the amount of energy gained by energy harvesting operations
    at these tops and bottoms.
    Now, if there would be a cylindrical (with the edges curbed towards the star)
    shape surrounding the star, that would be plausible.
    Not needing gravitational fields, and using centrifigal forces to keep from crushing
    itself, now that is highly plausible.
    Although actual construction would take 1000's of years and many exo-planet harvesting,
    this is well within the realm of possibility, and with that I mean plausible,
    not that mankind could achieve such like today and with current technology.
    The cylinder would still be an awesomely powerfull construction,
    since practicaly 50-80% of all the stars energy production would be usable.
    And that's a whole bunch a power.
    if the state of Texas is required, filled with solar panels to power everything on the globe
    as we need it today, imagine trillions of states the size of Texas, filled with solar panels.
    And even then the amount of land surface would be but a fraction of the cylinder.

    But no, sphere's not possible nor even usefull, since the amount of energy required
    to keep the top and bottom in place would exceed such energy harvesting.
    besides, the energy required to complete such a sphere with the top and bottom
    would be more pheasibly applied towards the construction of another cylinder.

    I often listen to videos like this while taking a shower and I've listened to this one a few times…I have a question…about the wow signal…has anyone considered that the signal could be one that was relayed from another part of the galaxy through a micro wormhole or something like that…ala star trek Voyager? was there something in the area not big enough to be a civilization but anomalous enough to possibly be a wormhole? Just a thought.

    If the "big bang" that started the universe actually happened and nothing can go faster than the speed of light, then when you look in the night sky and see nothing but dark your actually looking into infinitely

    I used to go to sleep some nights watching ASMRs of one beautiful chick brushing another beautiful chick’s hair, but now that I found this channel and subscribed I get to to start off learning things, then fade out to the sound of your voice. Could you sing Soft Kitty at the end of your videos…………..

    Thank you good Sir for a nice video, and hope you will get a great Halloween this year too.
    Also, thank you for putting the music in the credits!

    Thank you for setting the record straight on the wow signal. I get annoyed when I see so many people who immediately bought the comet bullshit. I knew right away when they announced it was comets that this “conclusion” would be debunked soon.

    Some people are so desparate not to have their "alien beacon" belief shattered that they even try to circumvent science…

    If I die then I won’t see the vast advances in awareness of our universe, but who’s to say that when we die we don’t get to explore the universe freely? What if the reason I’m afraid of death is actually why I should welcome it?

    As every day passes – It becomes more and more evident that – yes: we really are – alone. edit: Oh, and as for our favorite holidays? – Christmas and Easter. Not Halloween. Better to play it safe and observe holidays recognizing your Creator, rather than some made-up hocus-pocus hoodoo voodoo dates. Now THAT little tidbit of wisdom I pass on to you free of charge. You're welcome. Don't mention it!

    It would not have to rotate 40 times faster. A bit more probable is a "planet" with rotational speed similar to earths while the local aliens established 40 radio emitters spaced evenly around one of the latitude parallels. 40 is probably enough to send most languages on, even if used as a simple Morse code. In deed, such a frequency would probably fall with in the magnitude of most of our home grown devices. If they are placed as such, as I see it, very tight focusing into a remote region of space would become a simple engineering gig; while not having to defeat some law.

    By your logic I can just go "Maybe, just maybe, the world does not really exist. Maybe it's all just in my head. I mean they did explain to me why the world is real but I dunno. Just because I can't walk through a wall does not mean the wall exist, right?"

    I like to think of the signal at 14:30 as some alien ship that got lost in the void of space and was beaming a signal for help, but the signal drifted off its frequency as the energy on board depleted

    Mr. Godier, did Carl Sagan and his co-writer say Why an alien society might use plutonium to broadcast their existence? Is it because it is so scarce? The reasoning being that, if it is being used to broadcast, then there must be intelligent life there, because it would only be possible through extreme and dedicated methods to obtain and then utilize, and any civilization doing so and detecting such would know this. I'm just wondering if there is some science involved of which I am not aware. I stopped studying cosmology around 2002 because I obtained a tenure track position. But have had my interest piqued again amid all the recent attention being given cosmologists and the field. I am thrilled by the potentials this evokes! Is humanity actually developing some curiosity on a large scale? If so, this could bode very well for us if it is accompanied by temperance, compassion, and discernment. Could curiosity generated by the amazing images and data being returned by deep space telescopes become a driving force behind funds being channeled into space exploration rather than covert projects or military operations? I don't know, but it's exciting for me anyhow, to consider these possibilities!

    well.. some animals ex. polar bears cannot be seen on thermal cameras and its not all light spectres the human eye can see.
    so there could in theory be an alien standing right behind you at this moment . ?

  61. KILLER Post author

    a bunch of lies….they analize a planet or a star only just by looking to the light spectre, so if i look at kinder surprise planet , i analize just the package i prezume that planet is made just from the package materials ; so we can study and analyze stars and planets thousands lights years away from earth , but the 9 planet is hidding, we cannot see it….; we send robots to mars we can see pictures and movies about surface of mars, but we cannot film in the space , we have been to the moon , but we cannot back…..gtfo pseudoscients, only fake words, nothing proven…..

    Aliens put humans on Earth to study with their far superior technology. They created a life form (humans) by accident and wanted to see if this new life form could possess intelligence, so humans we're to be taken to a place (planet) where they could survive and flourish. But humans are very unpredictable due to the findings of alien researchers and are not trustworthy with technology far superior. So the aliens left humans to their planet and returned home and never returned, except a couple of alien scientist who volunteered to stay behind to monitor humans and relay information to fellow alien scientist back on their home planet.

    Are any of the dyson sphere candidates close to one another? (10 light years lets say)

    Mr. Godier is holding back. Planet X is real! Quantum computers were first designed to track its 23,000-year orbit around the Sun. The orbital path & dates of its return to our inner solar system were first published in Science Journal right after the turn of the century! Planet X will reenter the inner solar system in 2028 & after its annual romp around the backside of the Sun, it will exit the inner solar system in 2032!

    It makes no sense at all to me that we could have a Phantom Planet inside our solar system. How can we detect things so far away but we cannot detect a Phantom Planet with ease?
