- Have you ever wondered what would happen if a star passed by our Solar System? How would it affect the orbits of the planets, and the climate of Earth? Well, a new study suggests that this might have actually happened 56 million years ago, and it could explain a mysterious period of rapid global warming that occurred at that time. In this video, we will explore this fascinating hypothesis, and how the researchers used computer simulations to test it. Watch this video till the end to learn more.

I don't know about a Star passing by the solar system but we are in an orbit around the galaxy and our position is not static, so who knows what kind of forces are pulling on us, we're still learning about our own solar system.
It is nibiru the planet system that's heading towards us and as it does it pulls out the Earth and everything that gets in it way, that is what's causing all the earthquakes the floods volcanoes, the planet system is causing all of it it's like a big magnet, closer it gets worse everything gets, you haven't seen anything yet you're going to see things you never thought you would ever see in your lifetime, this is just a little bit of what's going on be safe ❤️
A little problem here that I am sure others have mentioned - 56 mys is not a long time and any star that passed by would not be going that fast as compared with relativistic speed - so where is the star?
We would certainly have become aware of a close star and be able to show it's trajectory had or had not passed the Earth - astronomers are pretty good at that these days...
It could be our star.
@@raycar1165 Yes, but the point was a passing star...
The sun orbits the galaxy once every 230 million years hence in 56 million years we have completed about a quarter of a galactic revolution. Most stars will be orbiting with us but that isn't true for every star - for instance stars from relatively recent galactic mergers, hypervelocity stars kicked out by the galaxy's super massive black hole etc etc. Hence it is possible that we wouldn't be able to find a star which came close to the solar system 56 million years ago if it was not generally orbiting along with us.
@@davidwebb4451could the Gaia star map, when completed in 2025, find it?
Very plausible. We do have a star that cyclically interacts with our solar system. The Sirius star that's responsible for precession at the equinox repeating every 26,000 years approximately. Majority of stars in our galaxy are interacting with each other, naturally since there's hundred millions of them (and billions of planets). So that's our second sun, which actually also has red dwarf Sirius B orbiting it.
But if a rogue star did pass by 56 mya we would still be able to see it and know it's size and mass and trajectory. So is there such a star, if so what is its name, size, mass and trajectory and what effect would this non-hypothetical star have had on the solar system, Earth and the PETM?
That's what I was wondering. I suppose it could of collided & merged with another local star. Do we have any rather large stars nearby? Is that why Beetlejuice is so huge?
The space between stars is vast. It's possible that the star could have hit another stars but very unlikely to have a direct hit. Also, if it did hit, we would see evidence of the hit. I think that the point of this paper was to open our eyes about the possibility of the impact of rogue stars on future as well as past climactic events rather than to suggest that a passing rogue star WAS the cause of the PETM -- as erroneously suggested by this video. The authors of the paper simply wanted to test to see if a rogue star could produce climatic effects and used the well known PETM event as their test case. They used only HYPOTHETICAL stars in their simulations. No ACTUAL nearby stars were evaluated. Unless an actual star is tested, the results of this study remains theoretical.
I was thinking that as well, and how close, my guess not that close, because I think we would have a lot more eccentric orbits, but keeping the mind open, but thank you for letting us to give it more thought
Small red dwarfs are especially hard to see. Maybe it could be one of those.
It could be the star we see today. The sun.
I can vouch for this. I was there when it happened.
I think this star cooked the dinosaurs to death. 🦕
@@danmurray1143I don't think the dinosaur grill has been been cleaned in a while. Might have to scrape it off for the upcoming primate BBQ.
Aliens killed off the dinosaurs because it wasn’t habitable for human like life. Or some deep under ocean dinosaurs would have lived and scientists argued some birds would have made it through a comet or asteroid collision and should exist today.
@@ikedougenhouser3585 nah they didnt have cameras back then, they only had cameras 55 million years ago
Oh that was you ?
I waved but I don't think you were looking.
Recently, I read about the search on planet 9. They have covered 80% of the search area and mentioned this study could reach it's conclusion in the next couple of years. If they fail to find a planet 9, it could very well indicate that a star is responsible for the perturbed orbits of the bodies in our outer solar system.
PLANET 9 IS THAT STAR. WILL PASS CLOSE TO EARTH.
Hang on. 56 million years ago? That's basically a few weeks ago in universe-time. Where's this star at? Shouldn't we be seeing it, still moving away? How fast must it be moving that we can't see it anymore!?!?
56 million years is long enough for the sun to have moved about a quarter of the way around the galaxy in its orbit and although most stars are moving in the same direction along with us not all are (eg stars from relatively recent mergers with the milky way, hypervelocity stars kicked out of the galactic centre by the super massive black hole there etc etc). Hence if a star which came close 56 million years ago wasn't orbiting around the galaxy in generally the same direction along with the solar system then it may be impossible to identify.
What David said, but more. A simple calculation will tell you the distance a star could have traveled in 56 million years. If the relative speed of the star was 50 km/second, that star would travel 9,333 light years relative to Sol in 56 million years. And relative velocities of stars can be more than twice that.

It may have burnt out or went super nova or maybe it didn't survive the encounter or maybe it's Proxima Centauri
@@robertjohnson7960 did not survive the encounter with the sun? If it had hit the sun, the planets would most likely not be here anymore.
I saw Bigfoot once
It is a hypothesis yes. It opens up new hypothesis and studies. It also talks about the studies limitations, so yes I went and looked at the original paper and it's very good. And we should do more studies on the subject
I agree , I really never gave this thought until now , it's really quite fascinating.
I mean , it's obvious that we are affected by gravitational forces from outside our solar system even now today. If that were not so we would fly away from the milkyway galaxy.
This study seems to be a first attempt to kind of quantify some of that and I think that is extremely cool.
I wonder if they could track nearby stars and see if there are any that might have had such a trajectory.
The answer is in 2 parts. 1, yes such tracking can be done. 2. a negative result does not imply that one did not. The problem is that the solar system in orbit of the galaxy has a periodic phase related to the mass of the galaxy itself that raises our orbit above and below the ecliptic. If we are talking about an interaction that resulted in Earth's orbit shifting some 50 million years ago, you would start with looking through this study for examples of the result, which is not conclusive, and work back through the study to approximately when the star in question would have been interacting with the outer system, and see if they include an estimate of the time of that interaction that may give you an estimate of the velocity of that star (or other massive body.) You may also find a range of mass involved in that interaction, which could dictate what category of star would have been involved. It is unlikely to give you a trajectory however. If you can start with assumed stellar class, you can eliminate stars that the duration would not involve a possible change in class for. I.e. unless that star merged with another star, it is unlikely that a G type star would have become an F type star. I'm not suggesting that such an event couldn't have happened, just that there would be other issues with that as well, such as the fact that such a merger is likely to have changed the resulting trajectory of the resulting star from the trajectories of either stelar body before the merger. Additionally if the class is a red dwarf, it is possible that the star may be outside of observation range after 50-100 million years. Likewise an extra galactic Stephan Wolf star passing through may have interacted with anything from no other stars to thousands of other stars, and each of these may be contributing to the confusion of what stars could have been interacting. I mention the latter because we would be talking about speeds in excess of the galaxy escape velocity for that star.
Again, yes, it's possible that you could look at the nearby stars, work out trajectories histories for them, and see if any of them might have passed close enough to affect the orbits of outer planets, but it's more likely that you would not find such an event, which doesn't mean it didn't happen.
I'm reminded as well of the idea of the Nemesis star that has been suggested as being in a periodic orbital interaction with Sol systems and randomly kicking comets out of our Kupier belt which are then credited with mass extinction events through the ages.
One thing we can say for sure, Humans didn't cause that global warming event, which doesn't say we're not responsible for the current one. Whether we are o not, perhaps we can learn from the events surrounding the end of that event to determine if we can influence the current event similarly. IDK.
the longest crime drama in TV history... we are on the trail of a hot suspect boss, I think we should be able to wrap this investigation up in a giga-lenium!
@@RNMSCthe GAIA star map, when finished, may be able to find the star, if it exists.
@@francessimmonds5784 I doubt it. 50million years ago we would have been almost a quarter turn back through our galactic orbit. There would be millions of candidates.
Exactly @@VincentNajger1
The most logical explanations and probabilities just as my thinking , “outside the box”. Is a must. Great video
No. Pretty bad. Mechanisms were not explained properly. why things got back to normal on a geologically short timescale wasn't even touched on. CO2 from vulcanism or massive releases of methane from clathrate are far more plausible.
Scholz's star passed through the Oort cloud 70,000 years ago. It's a binary system. That should have wreaked havoc to our system. Yet, don't think it did. So, it depends on the star system and possibly it's velocity relative to our in the milky way.
Simultaneously, our solar system passed through the Scholz star equivalent of the Oort cloud.
The so called "Ort Could" whichv still hasn't been proven and if it does the effects would take much longer than the when the star passed to disturb such objects. Remember the supposed ort cloud starts at about a light year out and maybe stretching out 2-3 light years. That would take longer than 70 thousand years to see its effects. One light year is 5.8 trillion miles
Oort cloud you mean the theoretical Oort Opic whatever
I would think the main factors would be mass and distance. A low-mass red dwarf at the distance of Scholtz's passage apparently didn't have much effect on the orbits of our system's planets. A more massive star passing a little closer: that would be the question.
@BruceK10032 red dwarfs can be many many many times more massive than jupiter and remember that star also had a brown dwarf tagging along which are way more massive than jupiter add them up and it's possible and if not the effects of ort cloud disturbance could take longer to reach us being over 1 light year or more and not traveling very fast. Lay off the sci fi and self preservation and open your mind just a little
I was expecting something like: the possible size of the star and how far it would have passed...
A speed of 50 km/sec would give the star a distance of 9,333 light-years in that time. Our own Sun would be invisible to the naked eye at only 50 light-years distance.
😎♥✝🇺🇸💯
I wonder if the passing star brought anything with it.
The possibilities are endless, especially for silly answers....
you mean like STD's
Herpes
Aliens 👽👾
Very solar centric to think it was the other star passing by. Maybe it was us who were crossing its path!
Could have caused cooling, too. You'd have to have clear differentiations which indicate a climate shift without other factors.
Well there is this. The earths rotation distance changes every 100 thousand years from an oval shape to a a more centric. It’s called the Michlovich cycle or something like that. Our present tightness is already that old. What causes that to change with such regular time frames? Was such a passing that long ago basically resetting the clock of this particular pattern with our star? We are not stationary. Our sun moves through the wheel of the galaxy and we are dragged along with it. Like a giant clock everything is a symphony of moving parts. One can imagine that this holds true of other systems that may periodically intersect with ours on a much larger time scale and this particular star that overlapped then may or may not now exist, or be so far out of our ability with existing technology to see it. It’s an interesting hypothesis nevertheless.
I believe a shift in the Earth's orbit would have a much longer impact than just a short time spike in temperature. I would expect the effects to last millions of years if not even permanently.
There's a place on planet earth called Bikini island where man set off an untold amount of atomic bombs off and knocked the planet out of it's originall orbit , now you're seeing global warming. No worries though it will come back into it's original orbit again it always does.👽🚬🍻
Not saying it could not happen, but curious to know how any number of atomic bomb explosions could alter the orbit of the earth. I can see how it might slow the rotation, but not alter the orbit.
Could it have been planet 9, also known as Nibiru?
It’s orbit has been said to be 23,000 years before it comes back into our solar system.
Nibiru no longer exists...
No. Planet 9, if it exists, will be less massive than Neptune and have little influence on the inner Solar System.
Look up planet Thea, that collided with earth when it was a younger planet. And that was powerful enough to create the moon. Some old scientist hate to accept it or they’d have to re write things but it’s the best solution to why we have deep underground oceans even under our oceans crust. And minerals brought to earth that helped form current life.
@pennypincher5516 Who said there is a planet called “Nibiru” ? And who is the genius that claims it comes back every 23,000 years? Inquiring minds want to know.
Has that planet even been proven to exist?
Scholz's Star passed our solar system as close as our Oort cloud system 70.000 years ago
And comets which orbits got disturbed by this passage are still in the way to reach the inner Solar System including Earth.
Wouldn’t astronomers know,from its trajectory if a star passed that close only 15 million years ago?
Probably not, because we wouldn't know it's path before we found it.
@@LordDustinDeWynd I think a lot of effort has gone into measuring positions and motion of nearby stars so they can run the clock backwards. It takes 255 million years for the solar system to orbit the galaxy so it seems feasible to me that a star passing 15m years ago would not be too far away.
@jerrycornelius5986
Where do you get 15 million years ago?
It says 56 !!! Million years ago!
Can we find which star that might have been?
Maybe.
But that amount of time is also MANY cycles of the precession of our axial inclination, our orbital eccentricity and changes to the axial tilt itself. Milankovitch cycles.
If these happened to line up appropriately PLUS a passing star perturbed earth, then the combined effect could very well be of relatively rapid influence on the climate.
Look up Milankovitch cycles if you don't know what those are.
@jerrycornelius5986 He said 56 million years ago. Not 15 million years ago.
Just pull a magnet past your Map compass , watch the needle start pointing at it and being released as you go past. Like our Lunar push and pull. On slo mo
Intriguing video, though still lots of questions to be considered. What music is used towards the end of this video please?
Not very distinct, sounds like something from hearts of space or night tides
I always thought that earth at one time was closer to the sun and also rotated almost twice as fast than it does currently ! That alone could explain earths climate changes ! 🌎
The purple dawn of creation story is an interesting theory.
Wrong. We have a very good idea of the variation in the Earth's rotation rate for the last few hundred million tears. It is all consistent with the recession of the moon.
@@rogerphelps9939 sadly mainstream science does not have an accurate model. It is based on gravity, the weakest force, so weak they now say it's not a force. This mistake is what the house of cards is built on.
There is evidence that our ancient ancestors have left for us, temples built to commemorate, carved into rock etc., that show us what we now recognize as plasma configurations.
Plasma configurations that have been confirmed by laboratory work.
Also depicted by the ancients are paths of the planets.
So we can guess based on computer models, which may give us a very good idea, or we can recreate the movements based on ancient observations.

Interesting theory. Recalls search for planet 9.
My favourite is interaction of cosmic rays and sun's radiation in changing climate. This gives good corelation.
THIS VIDEO DO NOT RECALL PLANET 9. PLANET 9 OR BLACK SUN, IS THE TRUE REASON BEHIND THIS VIDEO.
Sounds reasonable to me. I've wondered if this could have happened multiple times before in earth's history. For example (1) In the early solar system Jupiter was slowly moving in towards the sun. It then reversed and began moving further from the sun. Could the gravity of a passing star have reversed Jupiter's inward spiral? (2) There was a two million year "snowball earth" period around 460 million years ago just before the start of the Cambrian. Is it possible the pre-Cambrian ice age was ended by the increased radiation from a passing star? These are just speculations. Something I've wondered about.
I was thinking about Jupiter too when this video first played.
Allegedly
A close star gravitational perturbation being a potential cause of the Paleocene-Eocene Thermal Maximum is an interesting hypothesis, Though I didn't read the study, other proposed causes have likely methods of recovery. How did Earth recover from what is potentially permanent orbital modification? It would seem the warming should have stayed permanent.
Indeed. That is a glaring omission.
This video is pure speculation. I say it was dinosaur farts
The best explanation of PETM was a sudden release of carbon dioxide from volcanos that also burn vast subterran oil and coal fields (the worst place to occur a volcanic Eruption), ending to warm the oceans and release methane from deep sea ice chlarates.
This scenario are precisily the worst anthropogenic global warming scenario, and the HATM replays the PETM.
Nothing on the planetary/asteroidal collisions that also altered our orbit and climate?
Definitely would and has. It's what isn't in the theory that tells more information..
A flying star. I done heard it all now.
Perhaps Jupiter and Saturns orbits briefly lined up at certain times enough to affect Earth’s orbit.
It's certainly possible passing stars are affecting the orbits of the planets, but they would also have to pass right through the Oort Cloud to do it. In 1.3 million years, a star will be doing exactly that, and likely sending lots of comets both towards us and into interstellar space never to return while leaving new ones from it's Oort cloud in ours. It's very likely star systems ARE trading comets and other planetesimals with one another.
I ALMOST FAINTED until i read "56 million years ago"
A Large Comet that impacted the nearby objects close to Earth also is a consideration, because an additional moon dislodged by a comet would also cause a change in Earth's inclination and orbit distance. A moon larger than our present moon, dislodged would explain several changes that have residual effects that might have altered Earth's rotation and our present moons true earlier distance into what it is now.
In addition, Triton, the biggest moon of Neptune, fits into this scenario, as do the altered orbit of Mars and the loss of Mars's water, due to close grazing as the moon and comet both traveled out away from Earth. The Rings of Saturn and several moons of Saturn and two of Jupiter could actually have roles in such a comet collision, as well as the great flood of Earth. At least one of them. Triton could have been an advanced civilization lost to a comet and would explain alien landings and such from early Earth legend. Mars being barren would match up well with such a scenario. And the Rings of Saturn would explain the water stolen from Mars and later a collision with Uranus that left it listing and orbiting in a retro grade rotation and at an odd inclination. Triton, that moon of Neptune also lists oddly and rotates in retrograde, a mirror image of Uranus. Triton is a rocky moon with a nitrogen and ammonia marked atmosphere as well as with volcanic activity and low oxygen traces and little hydrogen or helium like Neptune has. Triton's surface is packed with what look like city foundations on one surface, while the other side is a melted mess, as if from a collision. Clues indicate it may have come from an Earth like location, not from a gas giant's condensation disk. It should be critically investigated.
Wow, great comment 👏🏻👏🏻
If you're not a scientist, you should be! I liked the video, but it was so short , it could have been well over 3 hours due to the context.. well done by you , and thanks for the video
Which passing star and the Gaia satellite may be able to back-track it if it's t.rue? Or maybe it's supposition, which is the way I'm leaning. Although Uranus is pretty awesome, but Earth tilt, moon.
You think my anus is pretty awesome!?!? I don't know whether to thank you or take off running.
Yes I know it's awesome , but please quit looking at my anus.
You should make a video about the part where it dropped dramatically after the PETM
as soon as he teaches his AI to not call Fahrenheit "Fur night"
Yeah, mmkay -- there also happened to be 2 huge oceanic flood basalt events going on about then also: the North Atlantic Igneous Province eruptions, and the Siletzia eruptions on the other side of the N. American continent.
Seems likely those volcanic events were the primary drivers.
A Blazar? Travelling 5,000km/sec having once been a twin who was drawn into a Black holes orbit its twin was pulled in and it was slingshot away?. It might still be visible?
I am curious to know which star it was. Did that interact with said star cause objects in our Ort Cloud to be ejected, tossed inward towards the inner solar system, or did that star steal some of the material from our Ort Cloud?
The Ort cloud would probably have formed as our solar system reestablished equilibrium.
Ancient texts and stone carvings around the world depict planets in a northern polar alignment. Where all the planets were in a line.
This may have been more recent than they suspected here. If we have records of it.
Maybe Ptolemy was correct, (when he was alive).
It is possible that we’re living in an ever changing solar system.
@@raycar1165 That is our Oort Cloud for sure. I was suggesting that a star passing by would disturb the orbits of those cometary objects within. The solar system has never stopped changing since its birth and will continue to do so. Shout out to Ptolemy.
@@HalloranIllustrations I agree.
Slowly the mainstream is going to accept a radical shift in how the solar system came to be.
I’m working on categorizing my playlists in the future to make them more specifically grouped together but feel free to explore them as they are now.
@@HalloranIllustrations This could be our star…
Interesting idea
There was a theory Venus is a stranger to our Solar system. A planet, never mind a star might have effects on climate.
The study did not mention the Shultz star passing thry the ort cloud 70,000 years ago...?
A common misunderstanding amongst many of your viewers (see other comments) involves the possible visibility of such a star. This would have been good to address in the video.
For instance, if a star had been traveling, relative to Sol, at the brisk, but rather unremarkable velocity of 50 km/sec, then after 56 Myrs, it would stand some 9,333 light-years from Earth. At that distance, the star, if still in the main sequence and similar to our own Sun, would be nearly impossible to see with the strongest of telescopes. Our own Sun would be invisible to the naked eye at 50 light-years distance. But stars range from extremely dim to extremely bright, relative to our own Sun. The closest star to Sol, Proxima Centauri, is invisible to the naked eye and requires a powerful telescope just to see it as a dim speck. Rigel (Beta Orionis), on the other hand, is so bright that, if it were to replace our own Sun, would stand at 57,000 times the brightness of Sol, likely turning the mountains into molten rock.
😎♥✝🇺🇸💯
If this scenario were true, I would expect a close approach of a start to have altered the orbits of comets in the Oort Cloud, causing a huge increase in the number of large asteroid/comet strikes, which we would see in the geologic record. But we don't see that.
Also, a one in ten thousands odds of such a close approach in a 100,000,000 year period is pretty slight. We would need to see some pretty good evidence, huge increase in meteor crater formations, to even entertain such a scenario seriously.
As far whether we should be able to spot that star if it occurred, 56 million years is a hell of a long time. The Constellations seen from Earth change a lot in just a 100,000 year period. If this occurred, that start would be a long way from our Solar System and I doubt we would be able to recognize it.
There are some who claim, inconclusively so far, that there is a rough periodicity to the rate of impacts. The rough periodicity is said to be about 30 million years. It happens that's also the period of our oscillation above and below the galactic plane. So the idea is that passing through a zone of greater density, such as the plane, which is also a sort of center of mass in two dimensions, increases the probability of impacts by destabilizing the Oort Cloud.
No doubt there are a lot of other variables that need to be taken into account as well.
Even if our climate can and does change due to a wide variety of natural causes, we would STILL have to act to alter the climate if we want to survive on this planet. Even if climate change was 100% natural and 0% human, we would still have to act. Why, because humans and human society can only exist and thrive within a very narrow range of climate that has existed for only the past few thousands of years. To permit climate to change outside that narrow range would first result in the collapse of human society and then the extinction of humans. Worse, other species, like humans, are adapted to the Ice Age, not the PETM. They can't just hop on a plane or run into an air conditioned building to escape a regional heat wave. Rapidly rising temperatures will result in ecological collapse and since we are completely dependent upon the ecosystem services produced by these species, we will be forced towards extinction as well. The goal is to produce an ecologically literate citizenry using ecologically-based and ecologically-constrained technology to create an ecologically-based and ecologically-constrained society and economy. That is our goal. Let's do it. Our civilization and our survival depends upon it!
First, the PETM is adequately explained by a Global Anoxic Event. Many occurred during the Mesozoic.
Second, the Earth's orbit is almost circular - barely an ellipse.
IF a star came nearby and altered Earth's orbit ---
I don't see how it could avoid a much more eccentric ellipsoidal orbit.
At moment, I reject this hypothesis.
I understand that it could have had, for lack of a better term, would have been wild.
But I also don't think we could have studied the skies for this long, and not noticed that something that close, and that massive had passed close.
It's a cool idea, and there is a lot I don't know about a lot of things, so keep digging, maybe we missed something, and never noticed.
Question: if possibly true, do we know which stars are the likely culprits?
Gravity is fascinating , yes the sun holds us in orbit , but I assume that same force is at work keeping us inside and orbiting around the galaxy.
Forces of Gravity I have to imagine are at work from millions of sources , seems almost amazing we can make the predictions we do as accurate as we do.
Even after 56 million years, the location of and the course within the Galaxy of a star that could have passed our solar system could by observed and calculated to identify any star that may have been involved in this close encounter. Has this been addressed or evaluated by the optical observatories?
What makes them so sure that a star passed by the solar system? It's it just as likely that our solar system passed by a star? The way everything is zipping through the universe on so many different trajectories and at a wide variety of speeds it's highly likely we've had lots of visitors and visited lots of different systems over astronomical time. It's even possible that some of the objects in our system were captured in encounters with other systems. Heck, we may have even lost some objects to other systems throughout it's existence. We are not so distant from other things after all and a great deal of things may have had various effects on all of the objects in our current system.
Always wondered if this happened
Since it is a highly hypothetical theory, how can I have any meaning about it would be possible or not? But it certainly is an interesting study. But is very hard to prove. The butterfly effect is so important here.
Any constraint against GAIA DR3?
The Nibiru system has been in our solar system for at least half a million years, according to the Sumerians. It is also known as The Destroyer, and Nemesis.
Amazing when you stop to think about it😉
Novel, But highly speculative
Ambitious and extremely complex. Celestial orbital calculations are nothing new, but looking for possible interactions / causes from soo long ago to back into some answer for changes to earth's atmosphere is a stretch. Kudos to the team on this huge effort, and for their honesty in acknowleging
That there is "no direct evidence".
Unfortunately, climate deniers will use this study to suggest that our current climate situation could be a result of this, or similar phenomenon. Critical thinking needs to be taught beginning in grade school.
Back inthe 50s geology books reported that there were 7 ice ages since the 🦕. Al gore stated that warming periods alter ocean currents and turn into ice ages. This might explain the volatility. Instability. If scientists still maintain that weve had several ice ages im curious what the patterns look like. Do they taper off. Are they less and less frequent. Why was there stability for so long when the 🦕 were here.
Which outer planet orbits outside of the plain of the soler system? Neptune or Uranus?
A passing star would have severely disrupted the Oort Cloud, throwing comets and asteroids into wild orbits throughout our solar system. Earth impacts would have spiked after such an event, yet we don’t see that.
If this occurred would we not expect a very rapid change to the climate, one that wouldn’t go away? The period of warm climate was gradual, over millions of years, and cooled back down considerably. A sudden and rapid change to orbit should be a nearly instant change on the geologic time scale.
I think that even a slight perturbation of the Earth’s orbit would be catastrophic. Could something have caused this in the modern era??
It does not need to be a star, but could have been a brown dwarf or close passing mass like a rouge planet. Any of these would no longer be detectable, since they would be more than several light years away by now. The gravitational pull of a brown dwarf or other close passing major gravitational force would also cause large amounts of Vulcanism, as gravitational pull often does.
Me an my girlfriend believe this study. We always say that a comet or asteroid must be on it's way close to us whenever we have strange an unexpected winds. We kinda think that like a boat in water going full speed and its pushing that water in front! Do you think it works the same way out in space with these rocks? 😅 just a thought 😊
Sort of reinforces the "Rare Earth" aspect of the Fermi Paradox.
Why doesn't Nasa use the quantum computer and plug in all the information from all sources and events that we have on file to determine what happened. I would love to see what’s going on
Not only can it not capture the full picture, it can't see any of it clearly. It can barely account for any facts with the lack of observational data. It's like trying to see a dimly lit picture on the side of a passing tractor-trailer at 65 mph going the opposite direction in a thick fog while looking through a fogged-up window. Using some assumptions is an understatement. Is it possible? Of course, but is there any degree of certainty worthy of a scientific paper? No way! It's science fiction at best, based on scientific principles. Like, the movie Interstellar with Matthew McConaughey. Good movie based on science, but complete nonsense.
A study claiming a passing star altered the Earth's orbit making it hotter would also have to explain how the orbit changed again to make the Earth cooler.
All in the life of a star; whatever that amounts to.
NASA: it could be a passing star, asteroid impact, volcanic activity or changes in ocean currents.
UN and YT: it may have been 65 million years ago but it's still your fault.
The star has to be enormous to pull earth from the sun's gravity holding earth in its orbital path.
The ancient Sumerians had legends of how a planet orbiting a rogue star caused havoc in our solar system. Breaking up a larger planet beyond Mars giving us the asteroid belt and planet earth. Thus why our planet looks like it does, with the Pacific being almost 50 % of our planet.
See books by Zecharia Sitchin and Immanuel Velikovsky for more on these unusual theories.
I just seen a video on this today bit it Said between now and September the star us 3,000 light yrs away and coming out way we will see it explode 💪🏾💪🏾💪🏾
So are you saying despite the meetup Earth had with Theia would not be enough to cause such a change?
The nearest star is Proxima Centuri and it's moving towards us, not away from us.
it can connect to gravity belt and bump it of course like moon is connected to earth belt causes tidal changes
There was a time when the Solar year was 360 days. Now it is 365.25 days. Since this is recorded, SOMETHING ELSE had to pass by to change the orbit within human memory. Moving outwards from the sun would have led to a permanent change in temperature.
In order for a rouge star to get into our solar system means that star would not have left. Also influence of a star would have wildly flung out our planets.
The climate/weather has only changed in the last 15-20 years!
Prior works might "..approximate the solar system as an isolated system and neglect our surrounding Galaxy...". Does this study isolate the Sun as an unchanging star? Did the Sun affect the solar system in a way that might drive Paleoclimate? What makes this better than a well-funded guess?
Since it was 56 million years ago, that would translate into about 1/5 of a revolution of the solar system around the galactic core. In addition the video makes no mention of the estimated mass or distance from Sol. Are we talking about a red dwarf passing through the Oort Cloud within a couple of light years of earth? Or something more massive, perhaps only a couple of light months from Sol? Also speed and angle of passage versus the solar orbital plane would contribute mightily to the disturbance created.
Unfortunately without more information, this is barely more than clickbait. Shame, the concept is intriguing.
The numbers I will mention are not intended to be exact, but rather to give a small approximation to my thinking.
The Sun circles the galaxy every 230 million years.
The Earth is approximately 4.6 billion years old.
The Encounter with this supposed star (PETM) was 56 million years ago.
Approximately, the Sun has made 20 complete revolutions around the Galaxy every 230 million years, since the formation of the Earth.
My estimate is that this PETM encounter could have been repeated at least 20 times since the existence of the Earth. Assuming the Star goes in another direction it simply passes by once every 230 million years. I mean, maybe that's the point to look for said star. One that passes close to the galaxy, once every 230 million years.
I'm not an astronomer, nor really a mathematician, so well, I'm probably very wrong, but that's what occurred to me.
Where is the star that passed so close?
It’s in outer space. Within 50 light years. So we should be able to find it with more observations and study.
Then again…..it could have been a rogue interstellar planet that passed through. A Jupiter sized object or bigger…..without a star.
A Jupiter sized object would have minimal effects.@@robertwilliamson922
Ok, if this is true, then the offending star should still be Relatively close to us in galactic terms, so which star is it? That should be relatively easy to determine if true.
Very solar centric to assume it was the other star passing by. Maybe it was us who crossed its path!
Well said! Giant fiery plasma lives matter!!
The accused, element creating, life supporting, atom fusing, light giving, space-time bending hot bugger should be given a fair crack of the whip.
What if our sun got in its way and it had a very important 56000000BCE lunch date with some foxy nebulae from east sagatarious?
Haters gonna hate.....
It was Not a star wanderer but the planet that was The Asteroid Belt today. It existed with habitable Mars. Earth was closer to the Sun and was like Venus today.
If a star passed by close enough to alter Earths orbit and climate. The star should be visible. Maybe if the star is a tiny neutron star it could be missed. Or possibly a brown dwarfe.
I wrote a program to play with this. See my videos. Some comments. Gravity is weak and any passing star will probably be moving relatively fast. Most stars aren't big. The inner solar system is very small and the chances of a passing star directly affecting earth are also small. Space is big the further you go out so likewise the effect on the outer planets. Jupiter is pulled into an 11.8 yr orbit around the sun by the suns mass . A fast moving star, say the suns mass, that passed in a month or so at a similar distance ain't going to do much. Most effects take 100's of years to be seen. The biggest risk is disturbing the asteroid belt since there are lots of them and hence more being close enough to be effected.
If we are to believe that a once ‘probable’ act of galactic chaos in the Milky Way galaxy started the domino effect which led to Earth’s ability to create and sustain man. Then, we must concede that it inadvertently adds credence to the existence of other life forms elsewhere in the cosmos and how they could thrive under similar CHAOTIC circumstances.
The scary thing is not if this has happened, but what could we do if something ever does alter our orbit?
We will NVR know the full past only enough to say it makes sense
A passing Star could have escalated volcanic activity on earth and caused multiple super volcanoes to erupt and put earth in a spiral of global warming events for thousands of years.
Stars pass within a light year about every 50,000 years & very often much closer
It just goes to show more than ever the importance of electronic cars and stoves...that star would've been to a scared to even think about trying that now days
i've frequently wondered if a large passing object might effect Earth's orbit. Thanks for reviewing this paper.
A star would disrupt the whole solar system, not just the Earth. We wouldn't be here. It was dinosaur farts.
Hmmmm, interesting but should we be able to look back to see if a trail is still following the system, another possibility is that we passed close to a small gravity well(aka Black Hole) ????
A black hole is not a small gravity well. It’s a huge one. Our moon is a small gravity well.
The size of any gravity well is pretty much just a function of mass so it is irrelevant whether it was a black hole or a star.@@robertwilliamson922
Most scientists believe that a planetoid about the size of Mars hit the Earth and the resulting debris created the moon. Could this impact be responsible for any orbit change?
Could something like this have happened in historic times? Records from Babylon on the motions of the planets were found incredibly correct according to our modern technical knowledge - up to a point, before which the records are faulty. The question: did something happen back then, since the records after that point are meticulously accurate to an extent that a sudden change to accuracy from being completely out of line with true measurements would seem unlikely. Could someone look this up, perhaps?
Did anyone else notice that the stars often appear to look like dna strings?
@@suefoster7317 I see them as vulvas.
If Earth was pulled to a new orbit, then we now have the answer to what tipped the scales for Venus
Well if the other star was going as fast as a saturn 5 rocket away from us that would be about 100,000 miles per year so in 55 million years - about 500 light years away now. Alpha Centari is only 4 light years away.
Certainly a one in 10,000 chance of something happening is "possible", just highly improbable. Research time and resources would be better spent on earth, sun and planetary related factors.
Next up a proposal to stop global warming by moving stars in our neighborhood.
