If you’d like to ‘see’ what the structure around Tabby’s Star roughly looks like. We previously spoke to Dr. David Kipping from Cool Worlds about imaging Tabby Stars structure: kzfaq.info/get/bejne/p82bqLultpvKaX0.html

Jupiter got a big dark spot that reappeared periodically as comet shoemaker crashed into it. What does a star do when something big hits it?

Truly outstanding episode, thank you guys. Your production quality surpasses PBS in my books, I don’t feel like I’ve wasted time on KZfaq after watching your videos. Thank you.

Guest says anything Mike says "what about aliens" We think the same sir

I know Event Horizon got its start with the first news of Tabby's Star so this is actually really cool to see things come full circle & so much learned in only a few short years.

Thank you John and the EH team. I love learning astronomy with your videos!

I remember a speaker at a seminar a few years back talking about there being old Harvard photographic plates with a red giant star that had some extreme dipping that was identified as repeating about 100 years later or something like that so yeah there is probably a whole lot of strange stuff out there in old data just waiting to be discovered.

Many thanks for not littering this video with ads, so most of us can watch it before sleeping 👍

amazing how astronomers are starting to figure out the mysteries of space as time goes on

I do wish Carl Sagan was still alive.Excellent episode.

Uploaded 8 mins ago. Sleep has to wait :|

Another awesome and incredibly interesting episode. Well done , JMG, and thank you. :)

If someone is an exceptional stellar astronomer, does that make them a stellar stellar astronomer?

We need Keppler 2 the sequel. Thanks for another great episode and interview.

I can't wait to hear more about this area of astronomy. Keep us posted. Fascinating!!

Can I just say... the intro music was pretty fantastic too

Perhaps it is in the interstellar medium, and the reason we only see the phenomenon with those particular stars is that they have each sent a massive armada our way when their local von neuman probe detected life here. It's not dust, it's an unfathomable amount of ships / probes / relativistic kill missiles, somewhere on a straight line between there and here. It's hard to figure out how close something is or how fast it's moving when it's heading for you in a straight line...

Thank u john and everyone involved in this

Wow I had no idea more “Tabby’s stars” had been located!!! Things get stranger every day, what an amazing time to be alive!!! Seem like tomorrow seeing alien craft in our skies will be normal than it already is.

It's fascinating how much we can discover just from taking a retrospective look at old data.

10:15 Be sure your name is included in the next paper.

Long time fan and going to stay a fan for a long long time.

Just a question to throw out for hammering. For various reasons there is room for thought that "we" are not alone. What if we are possibly seeing a failed Dyson sphere by an advanced civilization?

What would star lifting technology look like on a light curve?

"You! have fallen into event horizon with John Michael Godier, trapped together forever!" Nooooooooo!!!

Searching for info on Tabby's Star is how I found your channel John. ha ha

We are lucky to live during the 2nd space race.

I'm still liking the sunspots theory to explain the random relatively rapid light dip curves especially if these stars turn out to be rotating particularly fast.

This phenomena requires more research. Thanks for great information.

"... Weird ass-trophysical phenomenon"... I like that John. That was a good one , lol

Krypton is in a red dwarf system. lol.

Thanks guys 👍✅

Stellar heartbeats very interesting....

I like this show because of its speculation. Much more entertaining than real science. I used to listen to late night radio before the internet and the host would have guests on that claim they were in contact with alien civilizations. The stories were intriguing if if they were completely unbelievable. That is why I subscribe to this channel. It is like stream of conscious science fiction.

good episode

Fascinating

Its dark matter fields orbiting or traversing the path between the star and Earth. The gravity is diverting or lensing the light. The same explanation is true for planet 9.

Hell yeah! Stars!

Gah, on one hand this is awesome. On the other hand it takes away the mystique of Tabby's star. Oh well. That's the price of progress I guess. 🤷‍♂️😁

Probably should have another look at Zeta Reticuli when this new tech launches. If there's gravity propulsion, there may also be a way to "hide" things?

How about orbiting micro black holes? They would certainly mess up any planetary system, and leave a lot of dust...... just thinking loud.....

Is the Dimming due to the star losing its outer shell before expanding into a red giant since the classes of stars are similar this could be a possibility?

Fascinating stuff, maybe accretion in progress? Great stuff EH!👍

I thought it said "dripping" star, and I was like, "damn, this oughta be good"...

21 New Tabby's Stars! Number 14 Will Shock You

Could it be large planets with a lot of moons orbiting in our line of site around these stars?

Notification Squad where are you?

Has anyone considered that these "irregular" dips might be caused by an extensive planetary system? I mean, if the Sol system was viewed from the viewpoint of a star on the ecliptic, Sol's brightness would dip on a regular basis … but only if you had observations spanning hundreds of years. Perhaps we're just catching objects that are substantially farther out from their primaries so that no periodicity can be extrapolated from the limited observations we have … ?

Could it be 2 two stars, light years apart that are just aligned with our direct line of view? Thatd be super rare, but these seem to be super rare.

More satellites as soon as possible!

Maybe a planet with a lot of subsurface water is orbiting within the star itself. After a while, the water below the surface might get so hot that a steam explosion could blow off a significant chunk of its crust. If the crust is blasted into fine dust, the solar wind might be enough to push it out of its gravity well.

I think dissolving moons and planets make the most sense.

If you find a number of similar dipper stars with no IR trace then you can rule out mega structures. You might find one such star, possibly two, but if you find many, no way.

Can we please find dyson spheres already?

Would interstellar traffic, in the line of sight cause the dips?

2:30 start

Wow. So it isn't unique? That's crazy.

Here is a passing thought by a naive lay person. Could it be something that is non spherical such as a disc that is tumbling, thereby ocluding a different amount of light, depending on its orientation?

Let me guess, the Quantum Possum put the car in neutral!

What does a rapid dipper mean? I'm trying to picture this

Is it just me or does Dr. Schidmt sound like a sedated Donald Sutherland? Great video as always

Why not a kuiper belt of debris?

A secret only Tabby’s star can tell; The LINE hypothesis suggests that Ember Black Holes (EBH) are the remains of Isolated Super Massive Primordial (ISMP) black holes that have undergone all or most of a universe’s expansion and contraction cycles. With each contraction cycle of a verse, all black holes therein contract as they emit a proportional amount of Hawking radiation. By this process, ISMP becomes EBH black holes. EBH, therefore, carries the information which reveals a verse's true age. So, how can an EBH be found? Since EBH are as small as a black hole can get by any natural means and is, by definition, isolated for most of its existence, one could be forgiven for expecting it to be a significant challenge to find EBH in a circumstance conducive to extracting this valuable data. However, in nature, with proper consideration, the possible becomes practical. Consider that the mass of EBH’s may range from the very massive to being sub-planetary in size. Within this envelope, one crucial factor for the detection of EBH is the observers’ technological capability. For humans, in the year 2019 A.D., planet-sized EBH is the best fit for current human technological capability and accuracy in determining the age of this universe. This viable approach is to search for EBH’s which, after surviving countless universal contraction cycles spanning epochs of deep universal time, have been captured by a star’s gravitation and now orbits its host star as a typical planet does. These are solar EBH. In this approach, we may use a suite of exo-planetary detection technology and methods to study and mine the desired data. So, what to look for? What distinguishing features would a solar EBH captured at a stable distance from its host star reveal? In this endeavour, both the transit and wobble methods of planet detection remain options for the study of solar bound EBH. Solar EBH’s will display many of the features of a planet orbiting its star with one revealing exception. All EBH will lens light in a manner distinguished from a normal planet of any given size. In place of the normal atmospheric effect upon light displayed by some planets, instead, an EBH will offer a dynamic gradient of light distorting gravitational lensing effects as any black hole would. The innermost border of this lensing PH regime marks the boundary called the event horizon (EH). Near the EH the lensing distortions of light succumb to the gravitational well of the EBH which captures light in an invisible orbital sphere just outside of the EH. This is the wall of fire (WOF). The WOF is not directly observable and is a feature of all black holes, including the light feeding solar EBH. The WOF is the orbital wall of information created where the path of affected photons is curved by its gravitation into a closed orbit around the EBH. Within the WOF, photons temporarily neither fall into the event horizon nor escapes the gravitation of the black hole but are in a temporary orbit above the EH. Hence, as a satellite orbits its planet, light orbits the EBH. Because light is captured within the WOF, it will never be detected unless such light can somehow be perturbed into escaping its covert path around the EBH. As a satellite may be knocked from its orbit by external effects, so to can the light captured within this unusual orbit. Similar perturbations of the WOF can be produced by very few influences. Gravitational gradients are perhaps the only influences that can affect the WOF. As planets and other gravitating bodies tug on the Earth and moon and as the Moon gravitates the earth, EBH in orbit within an otherwise typical planetary solar system will participate in similar influences in due course. However, within the delicate balance that is the WOF, even a relatively minor gravitational imbalance may give light captured in the WOF just the right escape conditions needed to liberate information from this dark path. This lensing and emission of energy can occur constantly and sporadically around the sphere of the WOF informed by the local solar environment. Make no mistake, such emissions are not the liberation of information from within the black holes’ event horizon, since the WOF is not within the event horizon but is just outside of it. The difference being, information within the EH will forever remain beyond the influence of any external effect. Whereas, information within the WOF which is outside of the EH, may succumb to adequate external gravitational stimuli. The distinguishing light signature of a solar EBH that is properly aligned with its observer, will appear periodically during transits as it orbits its host star. A solar EBH, like a planet, is continuously bathed in the solar energy of its host star. The light signature of a solar EBH will be observed as a periodic but erratic and arbitrarily extreme light signature in place of what should be a diminutive, predictable, normal planetary transit signature. Unlike a normal satellite that can be knocked, boosted or thrown out of its orbit, and with the speed of light being constant on human planetary time scales, how then could captured light be similarly liberated from the WOF? The speed of light will remain the same for the duration of any foreseeable observation, therefore, it is only via the gravitational tidal effect of the solar environment that will alter the gravity well of the EBH. Not by altering the escape velocity of light but rather by high tide, if you will. The gravitational tidal effect in one location on the WOF will produce a low tide on some other location of the WOF. It is these gravitational tidal differentials that will permit the liberation of information previously captured around the EH. Low tide is in effect a reduction in gravitation which will act as a hole or opening through which a proportional amount of information possessing sufficient escape velocity may escape from the otherwise impenetrable gravity well that is the WOF. The profile of such releases can be quite tumultuous yet possess a certain periodicity indicative of planetary solar orbits. Tabby’s star is one such profile. The LINE hypothesis suggests that most of the observed perturbations in starlight intensity seen in Tabby’s star may be due to a combination of gravity lensing and photon capture and release within the WOF of an orbiting solar EBH under the influence of the local gravityscape in that solar system. Further, the LINE hypothesis suggests that the presence of solar EBH anywhere in one's universe is the sole indicator that this universe is a cyclic universe older than one universal transition event (big bang). The presence of EBH requires many cycles of universal contractions to contract an ISMP black hole to this diminutive mass. Solar EBH formation is not possible by any other natural means within the time span of only a single universal transition phase. To further refine the known age of one’s universe to its true age we must look into the light released from the wall of fire (WOF) of a gravitationally perturbed solar EBH such as the one orbiting Tabby’s star. The WOF is the invisible closed region of space-time adjacent to and outside of the EH which traps photons within a spherical orbit. Consider the perspective of a single photon trapped within the WOF. From the photon's perspective, it is travelling through space-time normally. The fact that the space-time of the WOF is a closed orbit around a maximally dilated PH regime of a black hole is inconsequential. Photons will travel for eons of deep universal time within the WOF oblivious to their circumstance even as the ISMP contracts into an EBH. Photons that have managed to remain within the WOF of an ISMP black hole for the entire duration since the universal instantiation event are called primordial photons (PPH). PPH’s are photons that, by chance, have never had the occasion to escape the dark treadmill of space and time that defines the WOF of its black hole. As an ISMP black hole experiences each of the universal contraction cycles, it liberates a proportional amount of information as Hawking radiation. Moreover, due to its isolation, it all the while remains significantly unchanged for each universal expansion. By this mechanism, the mass of an ISMP black hole diminishes as does its footprint and sphere of influence in space-time. In so doing, the space-time of the WOF in which PPH relentlessly orbits the EBH also contracts. For PPH this contraction of WOF space is no different from the contraction or expansion of normal space, each will produce a proportional Doppler shift in the PPH degrees of freedom. The LINE hypothesis suggests that the contraction of all EBH is informed by the universal information budget, and produces PPH that is proportionally blue-shifted in a manner equivalent to the manner in which the current universal expansion of normal space produces a proportional red-shift of light. Consequently, EBH are like time capsules for light. As emissions from a solar EBH are released by local gravitational tidal differentials, such releases contain a mix of photons from every stage of an ISMP’s existence, including the valuable PPH. The telltale degrees of freedom of PPH imbued with the long history of the ISMP’s evolution into an EBH is told by emissions of the most heavily blue-shifted PPH compacted within the WOF. The proper measurement of the degrees of freedom of EBH from the otherwise mysterious emissions of stars like Tabby’s star ascribes the litany of time that reveals the true age of this universe. www.amazon.com/dp/B07JHFDLSC

All that dimming. Who woulda thunk.

sounds like Paul Hellyer

Maybe they're destroying the inner planets in order to build a Dysen sphere....

Giant helium snow-balls ... How deep are the dips? A small percentage of the stars' brightness, or do they go to complete blackness, or what? EDIT: Never mind, I just saw in one of the graphs, a 7% dip in brightness. This HAS to be a gigantic and distant ring of planet-sized snow-men.

Would be cool if you call brian cox

the best, biggest minds in the world at the moment are,,,, Izic Arthur, Freakin awesome visionary X 1000 , Mike for the open minded & Steve For the Biggest thoughts yet, dont care if he is Right or not!!! Thinking outside of the BOX is what matters :D.

The Galactic Society is busy building Dyson spheres all over the place

We know that we dont know just yet. :)

Given that we've had all of this data for a long time, why haven't anyone written a computer algorithm that detects all data that don't corresponds with our current understanding of the cosmos? Seems like these dipping starts would've been discovered a lot sooner plus possibly other weird phenomenons we don't know of yet. Too much data? Too advanced physics? Are we waiting for the next giant leap concerning super computers?

So there’s things floating in front of them , duh

I wonder if some of the dips are from primordial black holes

Have they ruled out Morse code?

That was a boring guest.... ;-@ you could hear JMG really struggling trying to pull him through the episode.... great job! love event horizon! ;-)

This is probably an effect of other star systems in the foreground giving us incorrect measurements on what we intend to observe. A Dyson sphere is just a silly theory based on our earthly perspective.

Suppose we terra form a planet and before we move there, another civilization moves in. What do we do then?

Rephrase John not "tiny dust" fine dust sounds more correct if u don't mind my saying so John..

What if its not the universe inflating but every thing else deflating ?

Could be like the rings of Saturn...Made up by alien destroyed destroyed planets win/win !

Alien morris code lol

Get Dr. Becky!!!

Mmm only 70k subs but ricegum has millions. Logic these days

life in water will n dif---ever mak

It would be really good if a more critical analysis of Dyson Spheres as a marker for advanced civilizations could be done. Imho, even for a species so unimaginably advanced, it's a really dumb idea, the amount of resources required and the technology needed would negated the need to build a Dyson Sphere at all. The more I think about it, the more stupid the idea sounds. You'd probably have to pull apart an entire solar systems worth of materials just to cover even a little bit of a sun, and then you have to solve the engineering problem of protecting it from the sun, you need a Dyson Sphere before you have enough energy to build a Dyson Sphere. Its a dumb waste of resources and time! Back of the envelope maths would debunk the idea totally, you may as well expect aliens to start building solar roadways.

ok,life in water,so

Dear Event Horizon: Are you guys serious? It it true that- and I quote- " dimming and dipping of the star could be be of an alien civilization" Could it really "be be" of an... I'm not sure exactly what you were trying to say there. My best guess is that you wrote a 2nd "be" instead of writing "the result." That way the sentence would have read "... be the result of..." instead of "be be of an..." Anyway, my employment contract as a grammar nazi compels me to point this out to you guys. Cheers for the content :)

The cognitive dissonance of astronomers and space enthusiasts is truly amazing. Totally okay to speculate that blinking stars could be a sign of ET with absolutely no evidence, but try speculating that some of the phenomena recorded by the military may also be ET and they'll dismiss you as an irrational ufo believer. Truly astonishing.

"not real warm" American lexicon kills me 🤣

she wasnt the discoverer

I am so biased as I want to believe that these are the first signs of intelligent life and I hate the fact we are not putting every effort every device in space looking these anomalies as they would be the first tell tale signs & sadly remind me that humans are cheap and will only do things out of necessity not wonder. except when it comes to vanity items like fast cars or iPhones. -_-

Dyson sphere lol this aint star trek

Tabby's Star was discovered by some amateurs looking at recorded data.

Everyone looks d

First... booooom

Well the guy seem smart but very nervous and old?
