What's a factor of a thousand between friends :)

Piddly factors.

dawww i thought it was a tiny cute galaxy.

Weird, my brain heard the thousands. Maybe I was just expecting them?

That made me curious, is there a definitional upper and lower limit on what constitutes a galaxy? Like do you need at least a certain amount of stars or volume before it's a galaxy and not just a.. lesser-axy? And is it conceivable that there could be a galaxy so big that it would be more correctly categorized as part of some superstructure? Is there some kind of galactic roche-limit?

Well, they do have "SDSS J151713.93+213516.8" , aka the ring galaxy we can see behind Hoag's galaxy when we view it; a lottery winner booked up with a lottery winner than can probably see each other.

We're already in a very similar situation. Our Solar System is quite unique in comparison to the majority of other systems we've found... and it certainly leaves us scratching our heads.

Depending where you are in Hoag's Galaxy, you might not know the misfortune of your own shape.

@@Strype13 How is the solar system unique?

@@locoattack1210 The Oort Cloud,the amount of planets we have, etc

Hyaaaaaah!

This is what I was wondering as well.. many of the collision galaxies shown seem like they could look identical to the Hoags Galaxy if pictures at the right angle.

I think it would look more like... a ring planet, or, those pogo jumpy ball things. Where as a spiral galaxy formed as one unit, thereby having a more gradual connection between the core and the arms/ body; with a 25 LY gap in between the two, seen perfectly edge on, it would likely look like a ball with a plate through it... muck like a Saturn, except, well, a galaxy.

@@faulkgough1768 Did you noticed the correction (by Dr. Becky), this galaxy is actually 125 000 light years (not 125) and gap is 58 000 light years (not 58)

@@vesa.tamminen yes, yes, I did. The Milky way is 100,000 ly across. where she did not correct in the post is that does not make it the 20 some odd times bigger. She made a very good video, goofed on a few numbers, but still got her point across.

@Faulk Gough She said "it's about 25 percent bigger" not 20 some odd times bigger.

I had to watch this three times before I could hear the words . Her beauty keeps freezing my mind. 😍

@@maryseeker7590 Bet YT also spam you with a bunch of BS you don't care for. XP

In 1600’s Europe, she would been taken for a witch for her science knowledge and appearance.

With a big difference; she's actually a scientist who knows her stuff. Anton is a wonderful person, but lacks the knowledge and education level of Becky, which shows in their videos. It is (probably) fun to watch his channel if you have absolutely NO knowledge about astronomy, but if you do, you gonna get annoyed by his videos at some point :-)

@@merveilmeok2416 She looks like a witch to you? Jeez

@@silverXnoise wtf

She's way better than Anton Petrov. Don't get me wrong, Petrov is very good but he's just not Dr. Becky's level.

There's possibly a lot more truth in what you said than you thought. I've noticed that things form in strings in the universe . . . part way through I was thinking look in a line to see if there's another one.

It does look like something huge shot through it. Maybe a supper massive black hole, or holes, are in orbit around the central core and either ate all the stars or pushed them inward or outward.

@Don Mac It's AMAZING how many people out there have dreams/ visions/ near-death-experiences where they see Loki, but these foolish people misinterpret what they see and they _think_ they're seeing Jesus instead. Silly, silly, gullible fools!

@@Raz.C.... If I saw loki, I wouldn't think I had a near death experience. I'd think someone slipped some LSD in my beer.

@@thomasfleig1184 What I'm getting at, though, is how would you know if you saw Loki? For all we know, the Germanic people got it right and Loki, Odin, Freya etc... are the only real gods and the only reason anyone thinks otherwise/ believes in christianity/ islam/ thinks they saw jesus/ Vishnu/ etc is because of Loki's trickery.

A pair of large size black holes orbiting each other 10k ly apart, orbiting the core, would have sucked up all the gas, and ejected all the stars, from the empty ring. If two of us think this we must be right. How you gonna spend your Nobel windfall? I'm gonna build an airship.

Their orbits would need to closer the 30,000 LY and their mass would need to be in the 100’s of billions of solar mass to achieve this. Also when they spiralled down they would either interfere with each other and launch one or both into deep space and/or merge and the resulting blast wave of billions of solar masses being lost in the heat caused by this merger that we’d easily detect such an event clear across the universe assuming it was within our apparent horizon. I’m not sure this has been ruled out but since it’s reasonably obvious, but ludicrous, some first year has already tried and had the idea shot down, (probably hundreds of such students actually). I thought of this as well, but dismissed it for those plus dozens of other reasons, but definitely a really cool idea, just imagine it!

Good point. Maybe this galaxy will end up being the key to understanding dark matter. Btw they CAN and DO measure where dark matter is by it's gravity.

Ron Wilson there are some patterns Here is a good video

It's speld" hoax "boson

Surely you mean the Hoag's Bison.

Hog Buffalo??

I'll get on lit, as soon as I'm done with Hoag's Hoagie.

Or, the Higgs Bison.

I was thinking that, too. A galactic-level Roche limit? I don't know the maths well enough.

​@@sanders555 I was just wondering this very moment if there was some "third party" galaxy involved that got flung out of orbit, but I would think there would be some traces of such an object, even if an event like that happened billions of years ago. Unless! It was mostly composed of dark matter! Seems like a crazy number of coincidences, but then again, this seems like a pretty extraordinary object.

@@snowballeffect7812 Dark matter crossed my mind as well... Perhaps a combination indeed. Mr. Worf, program a level 3 probe with a trajectory into the anomaly and launch when ready.

1. get the numbers that represent your hypothesis 2. do the math 3. publish the paper in a peer reviewed journal 4. brag that you "solved one of the mysteries of the universe" (Sounds plausible enough to be worth falsifying)

It's not a result of anything gravitational. Gravitational interactions cannot account for accretion of stars from gas clouds much less the observed structure of any galaxy. It's an electrical phenomenon. The plasma current feeding that particular galaxy is what gives it the structure observed.

@@t00by00zer 1. get the numbers that represent your hypothesis 2. do the math 3. publish the paper in a peer reviewed journal 4. brag that you "Finally proved the Electric Universe" (Sounds like E.U. psuedoscience to me - publish and prove me wrong)

Your theory could be verified by long duration observation. If you have tge resources you could set up an observatory and make a lot of observations over several years. Then you coukd determine the movement of the ring structure. Of course determing the movement of the center mass requires very high magnification and resolution immaging. That means you need a very powerful tellescope.

Hoag's Object, is that a Black Hole you have captured in the middle of you, or are you just smiling for Earth's cameras?

Well, there have been a couple Ring Galaxies discovered of that type, however, we have never knowingly observed one directly head-on, and that's because there is no way of telling say The Whale Galaxy or the Cigar Galaxy of their galactic shape, as no defining features or characteristics are inherently visible. It's why we still don't know the nature of the Milky Way for this same reason. We're directly on the galactic plane of it.

@@GameKraken - Thank you for your reply!

Dark matter is an astronomics mathematical kludge.

Caldwell Transport Columbus, GA I don’t think calling dark matter a kluge really describes the situation usefully. We have, beginning most importantly with the surprising observations of galaxy rotation behavior by the late Dr Vera Rubin, good evidence that galaxies are surrounded by something creating gravity, a lot of it. Nobody has yet observed, despite looking hard, any sort of normal matter, matter that interacts with light, to account for this gravity, so the name “dark matter”. Perhaps a better name would be invisible matter, or invisible source of gravity, but whatever the name, there is something out there in space that we have good evidence for, but no explanation.

@@markholm7050 Or... our maths are wrong. But its much less embarrassing to say there is something wrong with the universe instead. So lets assign it an arbitrary bit of extra mass and energy so our equations match what we think we see. A "kludge" is accurate.

Prime dimensional space-time could be the answer for dark energy and dark matter. Prime one space time is a nano. If one can conjecture of a universe of Chaos in the Nano phasing of the Prime universe possibility. Imagine, or if you think about it, is there a possibility of a scale of astrophysics that is really really big. Bigger than all of our best instruments will ever be able to tell us. Within each Nano is the chaos of possibility and that we are stuck in a 3D Prime Nano space time. Since there was no Doppler shift looking for the center of the universe with the Big Bang Theory, Other kinds of universal interactions four theories are at play. What if all the possibilities of the Nano space time exist in the chaos field, but we live in a long time compared to the time of the phasing of the Nano space time. So prime one, is that so-called Big Bang Theory thing. And prime one is still in existence but not for our 3D sentient bodies. Everywhere in this verse prime-1 exist for part of the phasing of the Nano cycling in the space time continuum. And also, Prime 3D, Prime 5D, Prime 7D and etcetera Etc all going on within a billionth of a second in a nano space time continuum. If one uses the rubber band affect in the possible interaction of the Prime dimensional space within the Nano space time continuum, there could be a theory that sets up how the universe is constantly in chaos with dimensional Prime space, and as always returning to the zero-point reference of the non chaos universe within the Nano space time continuum. We don't understand the principles behind all this, yet. But it starts making sense, if one learns of the entanglement Theory, and the idea of time being a product of matter and energy interacting in the Nano space time phasing Covenant of the properties of the universe. In other words, in order to understand the grand large, one has to see the greater small. The phasing of the Prime dimensional spaces of the Nano chaos Matrix is what is in the mathematical mind of all the genius on the planet right now. These are very Advanced ideas, and the mathematics require a helping hand. When and if AI become sentient, this will be the grand question for AI to bring to the halls of Academia to take us again into a technological future. Once again, will have the flying carpet, the genie with the wishes, and the Open Sesame world of widgets. And the children of the whole wide world are watching

The calculations on where stable orbits exist apply equally to dark as real matter. The models of mass distribution are just as valid even if we can't see the majority of the mass.

That would drasticly change the mass of the whole galaxy and mass distribution. The orbits of the ring would be different.

Or if there is no IR signature, maybe they constructed stellar engines to move the star systems closer to the core, so as to reduce communication and travel times. Maybe they're constructing a Birch planet... Its nice to dream.

It's never aliens

@@raidermaxx2324 Until it is.

@@archenema6792 thats some pretty steep odds, since considering it hasnt been, so far.. :P.. ill take not aliens for 100, chuck.

I wondered that as well, but thought the distances may be too great. At the same time I also do not want to underestimate the power of Supermassive Black Hole collisions and what they can do to free floating non bound hydrogen gas. You may be right.

Stars can't be moved that way. It only works for gas and dust.

@@stefanschnabel2769 I'm not sure that's entirely true, but in any case the gravitational exclusion band described in the video would eventually pull the stars out of the empty area. It wouldn't clear out all the dust though. However, a shock-wave from multiple stars falling into a massive black hole would clear out all the dust quiet quickly.

So thinking bigger , it is whitehole that pushed everything out to more stable orbit. It is lonely that pointing something and it has gas but no other sources nearby.

@@marsamatruh5327 I was literally about to comment this and decided to look at the comments first.

I groaned but it was worthy of a thumbs up.

I suppose its not impossible but thats your go too? You dont look for a solution not requiring insanely advanced aliens before just assuming that?

There seems to be a nature bias...but honestly we should lie about it just to unify earth.

Of cause not, @Poul. I don't live to be a million years - which is required if I want to find out which it is first hand. So I might as well go crazy on conjecture, quickly seizing on the disciplines of philosofy as a guideline to extrapolate on stuff I am able to observe. For example, consider that weird question, "do God exist?" Using philosofy, there is one answer to this, that in it's simplicity and ability to satisfy both religion and science, must simply be true! (Although, always keeping in mind also that "the only thing I know with any certainty is, that I do not know anything at all" to prevent me from growing too frustrated at the state of things over the fact that cosmological timescales laugh in the faces of even our gravest concerns. It simply doesn't matter a thing, when you get right down to it.)

Great, just point me to the journal for citation!

Yeah, they can even answer "what 2+yellow". The holy books also have a lot of answers to everything. But there is one problem with all of them : they actually just claim "this is the answer" withtout any proof, so get out.

They have many interesting hypothesis and simple explanations. Only the old dogmas claims to know it all. At least they ask the right questions.

@@drgt3.1 exactly

@@drgt3.1 pfffft.. are you talking about the electric universe?? GTFO with that psuedo science mumbo jumbo.. lol. If I wanted alternative facts, I'd watch a trump presser.

So many words, so little sense.

Seachangeau. This new Electric Universe myth is becoming more like a cult, desperately trying to force Nikola Tesla and Jesus Christ into astrophysics. Have some shame, man.

Is this another conspiracy like the flat earth? It sure seems like it. Too much technobabble than any sort of explanation for their claims.

@@henzy7397 It is, they call it the Electric Universe. Most of their followers have never taken a physics nor an astronomy course in their lifetime. They think the universe is a vast field of electricity where galaxies are powered on by plasma cosmology. It's psuedo science.
