- The first interstellar object, named 'Oumuamua, was discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii. The object is of unknown origin and could be a comet or asteroid. However according to a recent paper by Dr. Avi Loeb of Harvard University and Harvard Smithsonian Center for Astrophysics, it may possibly be an artificial alien light sail. We spoke to Dr. Loeb about that paper.

Perhaps it is highly magnetized and is acting like a magnetic sail, being decelerated by the deflection of charged particles from the solar wind.
FACT of GAS BONDING totally destroys Einstein's space Bending and Newton's mythical Gravity.
All downward falling motion begins when active rising gas molecules as an ENERGY FLOW becomes trapped gas molecules within the process of making solid objects with trapped ENERGY LOCK lifeless dead gas molecules, which as dead gas molecules can only fall downward. This is scientificly known as the mechanism of GAS BONDING, which take on a state of solid mass blocking out its electrons motion, it's fire power, thus becomes ENERGY LOCK lifeless gas molecules, and falls downward in real time, fallowing it's Electrons Unlimited Potential Velocity at the speed of light connects with the earth ENERGY CONSERVATION SYSTEM , establishing a downward falling path for trapped ENERGY LOCK lifeless dead gas molecules/solid objects only.
Equating the above FACT with the physical universe, same as Einstein's E = MC2 equates with the physical universe.
E = ENERGY = MM = MOLECULE MOTION = Molecules in motion within star flames earth gases birds and balloons plains and rocket's, even us humans rise from molecules in motion creating an ENERGY FLOW, the ruling force of the universe.
M = MASS = GB = GAS BONDING = Gas Bonding take on a state of solid mass blocking out its electrons motion, it's fire power, thus becomes ENERGY LOCK lifeless dead gas molecules, and falls downward in real time.
C2 = LIGHT SPEED = E = ELECTRONS = Electrons Unlimited Potential Velocity, at the speed of light connects with the earth ENERGY CONSERVATION SYSTEM, establishing a downward falling path for trapped ENERGY LOCK lifeless dead gas molecules/ solid objects only.
Gravity is a mythical concept that's mentally applied by Newton, solely to guarantee needed results to it's point of origin, the BRAIN !
This they should've known !
@@rayagoldendropofsun397
The gravitational constant was quantified by the Cavendish experiment, an experiment that can be recreated in the industrial arts facility of almost any high school. You are asserting falsehoods that are readily falsifiable. You naively state crap on the assumption that it can't be checked, but just because you don't know how doesn't mean nobody knows how. Things falling are not the only measurable effects of gravity.
@@digitalnomad9985 - If the mechanism of GAS BONDING is a FACT, then there's no such thing as Gravity/Gravity constant. The above post GAS BONDING clearly explain how and why Newton's apple fell downward, apsent Gravity. The measurements of motion within Cavendish experiment is nothing more than atomic energy flow between objects that's free enough to visibly respond to such level of energy, energy that's exerted between them from atoms/electrons that's trapped within the molicules of solid objects . This work the same way with all trapped gas molecules, it's electrons will always reach out to the nearest strongest signal available. The experiment U mentioned that's done is schools, should they spot a light on either end of that hanging bar, it will come to life in motion, which is ENERGY FLOW. Try it ! Or U could hang a small object on a eighteen inch piece of thread, spot a light on there when motionless, it will come to life.
@@rayagoldendropofsun397
If gravitation and gas bonding are, as you say, mutually exclusive then gas bonding does not exist. Gravitation has been experimentally confirmed and explains not just why objects fall locally, but the motions of the planetary bodies. It is the basis of calculating the trajectories of space vehicles.
It would be interesting to find out how many cats have been named Oumuamua in the past week.
Another superb talk by Avi Loeb.
Many of his papers may be found on the arXiv website. He has authored hundreds of papers that are required reading for those seriously interested in the habitability of the universe and exobiology. These are exciting times and Avi Loeb is amongst those astrophysicists I follow on the arXiv.
Indeed. We linked the relevant paper in the description.
I didn't hear any actual effort from him to translate his professional arguments for the public. It was poor speculative bla-bla chat. I was hoping to hear more about his paper and some actual arguments and more in depth explanation how light sail transportation works in general and in the case for Oumuamua.
To start - the shape is very far from perfect sail. He only said it have to be "thin to work". he didn't explain why/ and how Oumuamua is less than millimeter thin. WTF?
My guess is that when we first encounter alien technology we will not recognize it.
exactly why the concept "light sale" is just primitive
I respect and enjoy Dr. Loeb very much. Glad you’re bringing him back on!
.
Dan Cook same bruh
I like to dream too, but as the guy from PBS spacetime says: "It's not aliens, until it is aliens"
media.makeameme.org/created/im-not-saying-hs2yuz.jpg
Yah, no. That guy is part of a group of boring, jaded scientists who’ve collectively lost their ability to imagine or accept anything outside their little spheres of knowledge. We need Carl Sagan back in a very big way. His video came out when Oumuamua was first discovered and he made assumptions and dismissals that are now being seriously considered. He’s the perfect example of a scientist lacking an open mind.
@@JustinLHopkins I like Carl Sagan, but you seem to have the wrong impression of him. He wouldn't have assumed Aliens. Its stupid to be so open minded your brain falls out.
@Madara Uchiwa I DON'T WANT ANYONE PUTTING CHEMICALS IN THE WATER AND TURNING THE FREAKIN ALIENS GAY!
In August 2023, they will make first contact with us and claim responsibility for Oumuamua.
Such an intriguing object! We must chase it lol
Now I finally understand my dog constantly chasing the UPS truck.
MDZPNMD indeed. Your dog just wants to study the ups truck and understand how it was formed and from where it originated.

the JMG channel is very entertaining, but you are killing it over here at event horizon! thank you for all the work you do.
Glad I woke up at 1:30 am. :D
Woke up at 12 am to watch this
Good lord, two uploads in one week? You spoil us! :)
You guys should do regular updates with Dr Loeb if at all possible. I would love to hear what's going on with Star Shot and/or what's up in general. He really grounds my skepticism and gets me to review my biases in a unique way.
I tend to scoff at these kinds of theories, but he makes valid points from an open perspective. While I maintain my skepticism, I haven't heard someone so knowledgeable and authoritative propose these types of arguements in a plausible way that appears mostly independent of a confirmation bias. That's a powerful tool for creating change. I know Dr Loeb is a very busy man, but hey, if Brady Haran can pull off all that he does with so many of the awesome professors and professionals he manages to record on all of his different channels I imagine it is quite possible to find a way for this kind of content if one tries hard enough. Just look up all the recognition that has come from Brady's Periodic Videos channel. That channel was a major contributor to the Knighting of Professor Poliakoff. These kinds of channels are the mainstream media of the future and are quickly becoming the current defacto standard. I watch YT instead of traditional cable TV and many others are doing the same. This could just as easily become a great opportunity for Dr. Loeb just as much as it could be for the channel. This channel is ideal for such content and collaboration. This would push the boundaries on content depth and public exposure, while in my opinion, this channel's format and style is perfectly aligned to translate the typically verbose language of academia into something far more palatable and appealing to those of us with a more casual interest in these subjects.

I really hope we get to chase down Oumuamua in the near future. If nothing else, we should slap a bumper sticker on it and then leave it to its course.
Who knows? Maybe in a few million years it'll make its way back to our system covered in alien stickers!
Cosmic radiation will white it out and space dust will cover it.
Space sucks
No Name thorium powered radio?
Kind of disappointing that after decades of space exploration, the best thing we could do was this much and whatever we might gleam later. Pretty much like watching a super car passing us at top speed, we know it's fast, we know it's red, but other than that, might as well be a super fast banana for all we know.
We shouldn't be disappointed it just proves how hard it is to do things in space its a amazing that we even detected this object it'd be like detecting a spider in the Sahara dessert while sitting in new york
@@benny5190 With something around 7% or less of the global GDP being dedicated to space, we should at least feel slightly ashamed.
We have had the means to get into space and begin colonizing (or at minimum industrializing) our local space since the 1980s. Instead we've been too busy planning coups, terrorizing each other, creating racial tension and throwing an ever increasing amount of horrid 'entertainment' out to keep the masses ignorant and consuming.
If we spent less money trying to kill each other, and stealing our neighbors secrets, we could already have working space elevators and orbital rings.
@@MoonMoon-gu2ge i know i totally agree we pay celebrities and footballers crazy money then we spend 500k on a missile to send over an imaginary boarder to attack our neighbours id rather see that money go into the space programe
It's what people wanted. "Stop spending billions on space when we could spend it here on Earth on makeup and football - er, I mean ending poverty..." blah blah blah blah.

Been hoping for this specific interview, time to check out this Pathreon page of yours.
@@stevenutter3614you are right. In my defence im not a native speaker and do not employ spellingchecker.
Seems like a bit of sensationalism considering the scientist is working for a company to develop light sails, it would make sense to attribute Oumuamua to being a light sail just to raise awareness of the viability of such a technology.
Sans Handlebars whoa I didnt know he was involved with a lightsail technology company? That does indeed kind of skewer further the opinion he posits
@@JuiceBlack Listen to this video again: @ 3:55 Dr. Loeb states he is heading up a project called Starshot for a company developing light sail technology. @ 6:34 John Michael Godier asks about catching up to Oumuamua to which Dr. Loeb responds with criticisms of chemical rockets and @ 7:22 he plugs Starshot once again suggestng that it could outperform chemical rockets in terms of speed and could have caught up to the fast moving Oumuamua. Even the way the entire interview was structured and the clickbait title suggest that this was all planned as a publicity stunt.
Sans Handlebars yea for some reason that all went completely over my head when I watched the interview lol makes a lot of sense now though
@@JuiceBlack For me I began suspecting something was up as soon as he said he was the leader of a project involving light sail technology. From there I listened closely and if you do the same, the good Dr. adds just as much speculation and opinion as he does science about Oumuamua. He doesn't really treat the subject all that honestly in my opinion. Seems like he's stirring the pot by raising fantastical concepts about alien recon probes using camouflage and an emphasis on how we could have been able to find out if his project was already up and running (like a subtle invitation to invest in his project). Even when confronted about the flaws in his theory about the asteroid being a solar sail he redirects the attention to something else. Such as the fact that the thing is tumbling awkwardly with no set surface remaining consistently directed to the sun (which a light sail would need, just like how a sail boat positions the sail in a set position to catch the wind - a sail boat doesn't flap its sails in all directions and spin end over end). When confronted about the awkward trajectory he deflected to the possibility of either a "defunct piece of equipment" or a "form of camouflage ".
John Michael Godier is also one who subscribes to the idea of "it's never aliens until it is" mindset and I find it interesting that he didn't ask any questions of how a light sail could form naturally.
@@ashIibabbitt1111 Sure, "aliens" is always sensational. But talking about his light-sail project...that's probably just the thing that's often on his mind.
I also find the trajectory of the object to be intriguing, the fact it has crossed interstellar distances and yet swung so close to Earth. The tumbling may indicate a collision or gravitational interaction in the past, suggesting that if it is artificial, it’s ‘dead’.
Or it wants observers to *think* it's dead...
sunspot42 heh. Perhaps!
its tumbling is a speculation only. it can very well be a rogue moon like Saturn's Iapetus with dark & bright surface. even iapetus's brightness varies by a factor of 10, just like Oumuamua.
I love when you have Dr. Loeb on. Thanks alot for yet another great episode. Looking forward to your next video on your regular chan too. 🤘😎🤘
New JMG video soon....
Maybe one day a society will be having a similar conversation when they see Voyager pass by.
good point !
The content on this channel is unbelievable. I hope it gets as big as Isaac Arthur
Of course its aliens, just look at the name. What human would name it Oumuamua.
Thanks for the laugh, dude!

@@kalsizzle Yep.
You continue to outdo yourself, John. Great work.
Ok. QUESTION: Where is Oumuamua going after it visits our solar system? Interestingly the trajectory of Oumuamua shown in the video visualization had the Omu flying inward and from "above" the plane of the solar system. Then dipping "down" into and under the plane of the solar system. Finally Ou turned up, over, and away into interstellar space. (As shown in the cartoon visualization of the trajectory.) Any more solar systems along the trajectory as it moves away from us?
Holy Smoke Event Horizon twice in one day..thanks JMG..greeting from australia!
Thanks. This was something special, he had a few minutes so we went for it.
@@JohnMichaelGodier, and your audience appreciates it!
Dr Loeb and JMG in one conversation. Pure brilliance!
Enjoyed the interview. Would've love d for it to had been longer
I remember the first thing that came to mind when i say this on the news, it looks more crystalline than asteroid, being more elongated than rounded. I would expect asteroids to develop around other asteroids rounding them off a bit like stones on a beach, whereas an elongated structure could have grown as a crystal or broken from a larger structure. But in the end its just an interesting speculation, like could a crystalline structure be affected by external forces differently to an asteroid, or am I just going off on a tangent.
JMG - this a major scoop for your channel to get this guy! amazing!
We need Starshot ASAP! Who knows how many "Oumuamua's" have visited our solar system in the past. If it IS artificial, this would be the greatest discovery in our history, the knowledge that we're not alone. Great interview!
Imagine if alien contact is few decades away, imagine the level of unification that would cause. It's amazing.
*It's safe to say if there is a question in the headline, the answer to it is usually NO.* Thanks for the interview with him though!
Does a human work?
@@JohnMichaelGodier Was your response a headline?
*"if there's a question in the **_HEADLINE..."_*

Very interesting !
The Exoplanets Channel indeed !
The Exoplanets Channel it certainly is
The Exoplanets Channel i agree
Imagine how funny it would be to be one of the alien scientists using this thing to observe us as it passes by just seeing rockets flying up at it trying to catch it and failing.
Best video I have seen on the subject.
Great bonus video! Man, just imagine the implications if we can confirm that this or another object is a defunct piece of extraterrestrial technology! Crazier even is if we discover more than one such piece of debris......
The 1959 Brookings Report and the DoD SOP preclude us from ever knowing if it's et tech for now and the foreseeable future. Unless, and until, we break apart the "intelligence" groups of the US MIC, as JFK intended, it's simply never going to happen.
Maybe worth finding out if it is heading towards another star which would suggest that it is not on a random trajectory.
Oumuamua becomes stranger and stranger every day. The new information coming out is truly incredible and mysterious. Anyone who flat out denies alien life amongst the universe is the height of ignorance.
it is also possible that only objects of this strange form are able to escape other solar systems.
what is very interesting in my view is the fact that the very first outer solar object we found has these strange properties.
we have ONE sample of other sample objects and already it acts and looks this strangely.
yes, it can be artificial, but we should also ask ourselves what form do we expect from outer solar objects?
what properties should an object have in order to have enough energy to escape the gravity well of a star?
Wow! That was exciting news indeed. I am so intrigued by this object to think that it could have a solar sail is exciting. Thanks John for sharing this it made my day!
As someone who has studied warfare quite a bit, it seems to check quite a few boxes of a military probe, especially the fact that it was coming from a position in space that would indicate concealment, very much like a reconnaissance mission. Most intriguing. If I had to guess it was probably studying things like our our nuclear weapons capability. Just my opinion.
Talk about podcasting street cred. I doubt many could have brought on a more relevant guest so recently following their being the focus of international news.
This screams the Rama spacecraft depicted by Arthur C. Clarke!!!
If he had only lived another 10 years...
Except it's tumbling... or is it, in fact, flashing a beacon?
Or possibly, "Starglider " .
Great interview. Just curious why we only identified the object prior to it leaving the solar system when we have powerful telescopes all over the world. One would think we would have noticed its arrival just by virtue of its sheer speed against the backdrop of other static objects.
A Truly amazing interview.
We should test one of the Project Starshot probes by sending it out to rendezvous with Oumuamua
I have to keep saying it. The fact that we didn't go out to meet this object is outrageous. Or maybe we actually did. Edit: Just got to the part about that. Let's do it.
Not only does movie director Alejandro Iñarritu create amazing films, he also has a lot of knowledge of the universe.
_If_ it was an interstellar probe and it was using the electromagnetic spectrum to communicate, it'd make sense for such a communication to be _highly directional_ (some kind of laser, probably) in order to save as much power as possible, wouldn't it..? In which case we'd only be able to intercept its communications if we were right between it and wherever it was communicating with...
While I don't think Oumuamua is "alien" in origin, it's still worth chasing it just for the science. And who knows, maybe it'll turn out to be Rama...
Technically it is ALIEN as it comes from another solar system, regardless of whether it's a natural or artificial object.
I'm curious....at what point did omuamua accelerate? Was it after it was well away from other planets, or was it as it passed them? If the latter, it's simple gravity slingshot.
Thats what i say its as it passed the sun and got slingshotted i dont get why people think thats strange thats what happends when u pass the sun and get thrown out you go flying out and speed up lol.
Slingshots need thrust.
David, is it truly possible that no astronomer on Earth has considered such a possibility? ;) Going by the animation it is not on the ecliptic and does not appear to have been anywhere near any known planetary body when it accelerated. Perhaps we should look for a hidden planet in a highly irregular orbit around the sun though just to be sure... that's at least as crazy as aliens, actually maybe even more crazy. ;)
banana rama I don't think you understand how gravity slingshots work, or even what the post you've replied to is suggesting.
Thanks for the interview - I'd like the next layer of detail. Why, for example did Dr Loeb's analysis require the material to be thin - less than a mm? And what do we know about the mass of the object and its dimensions? And how? I think perhaps Dr Loeb is saying is that the solar wind is enough to account for the anomaly in the object's position if the object has a relatively low mass (and is therefore necessarily thin). I think estimates of its dimensions come from the variation in brightness. Do we know anything about its mass? And what can we say anything about its shape?
Finally a scientist that is looking at this rationally and with intellect .. these are identical patterns to my own thoughts on the subject!! He's not merely reporting observations but he is taking an analytical approach by projecting the data along all the inferred and relevant vectors. Pay attention to what this gentleman is saying!
Great video with the OG
How long will we be able to monitor it for before it moves too far away?
It really captured my attention...
If it was a solar sail, woiuldn't it slow down as it approached the Sun, or be pushed into a slightly curved path?
Maybe its somehow retractable and it opened on the way out only, or more likely its from a material able to switch its sun propulsion properties on/off.. the way we can switch the conductors etc
A solar sail can generate acceleration in any direction in a 180 degree window away from the light source.
Saying ETs don't exist is like taking a cup of water from the ocean and saying fish don't exist because there were none in the cup
Get that Starshot working so that we can at least catch up with the next one!
A good reason to go back to the 'Rama' series.
Is this channel new?
It's very very appealing so far! You are really good as a host as well as the narator of your other channel. PS Get Paul Davies some time if you get big enough to get his attention ;)

Is Oumuamua heading to another solar system or significant gravitational body
Yes but not for a very longtime.
Possible. It’s been traveling the cosmos since before we evolved. It’s all very interesting.
Jason Gannon dude it saw how we were acting and said fuck that and dipped out to another solar system
@@AdRock Which one is it heading to now, out of curiousity? If it really is heading right for another star after its course correction, that is a bit *too* coincidental even for a hardcore sceptic...
@@mikicerise6250 thats actually a very good point i didnt think of that
Fascinating topic!!
Isn't a solar sail traveling at a high speed precisely what we would send to explore another star?
Love JMG stuff. But much greater quantity could be achieved by doing some of these as podcasts rather than vids... the video tends to not be that relevant anyway and distracting. I don't watch the vid I just download and listen to JMG and friends on mp3 player because of the excessive ads. This is a great audio program and no need to waste so much JMG time injecting video, or my time dodging 4 ads per upload.
I keep thinking I'm looking at an actual photo of this thing. Any good pics of it?
None that we could find, though that may change come Monday.

Here you go. JMG'S Interstellar Asteroid Oumuamua Update for 11/07/2018: th-cam.com/video/NJBr3Zcb21I/w-d-xo.html
Ya know -IF -let’s say IF this was an object from another civilization checking in on what’s going on here on Earth -who’s to say that civilization is even still around?
How fast is Oumuamua traveling? -something like 200,000mph? So wouldn’t that still take hundreds or maybe thousands of years to get to the nearest system to ours? The people who sent it could be all dead by now....
Maybe the object just slowed down when it entered in our solar system.
It was intersteller not even sure where it came from or if its even from our own galaxy so were talking millions upon millions of years hell maybe even billions
Is it possible that it seems unique only because we just started looking for these extra-solar objects? Would it be possible from this distance to tell if it was using laser or ion propulsion?
I believe that object came from a bang. Either explosion or a collision but it's strange how it's it's moving and the direction it's heading.
New video later today that supports that.
@@EventHorizonShow noice! Can't wait
Thanks for the great show! Your animated images remind me of Clarke's "Rendezvous with Rama", if we see two more - then we're in real trouble!
It would be interesting to know where the extra acceleration happened and when. More importantly, is it still accelerating, or is the speed what would be expected now of an asteroid-like object?
So it could quite possibly be a solar sail from another civilization ? That's astonishing !!
Any idea of the mass and size of this object ? very interesting
Imagine if Voyager 1 has hit someones planet and they send Oumuamua to us.
It's never aliens.. until it's aliens.
How do we know if it's aliens? That's why we need to investigate, otherwise we'll miss the aliens when they're there.
It's always aliens until its not aliens.
Unnatural object unnaturally moves through the solar system while unnaturally changing speeds etc. I'm not saying it's aliens but if not aliens then what? Humans from the future?
The more I think about it, the more I think the 8 hour wobble maybe nodding. You know point at a target move off and then move back on to make sure it’s real. It’s exactly what we do.
Thank you for the video!
Wait till they say things like 'it has been detected that previously unknown objects or parts of the meteor have broken off and are in a close trajectory near the earths area in space...'.
Scout, more like scout ship.
This is right out of a Sci fi alien movie. !
It's oblong. Could one end be heavier than the other, making it travel with the unexpected trajectory? Picking up speed from it's awkward momentum. (Like an iron core on one end.)
One of the concepts that Humans had come up with for gravity in space, was to have a spinning or rotating craft, which creates gravity through centrifugal force. Perhaps this was an actual encounter with the Black Knight satellite. And once it knew we had detected it, it had sped off.
I like this Avi Loeb guy.
Could it be an effect of it tumbling at just the right moment with it's elongated shape like a trebuchet arm?
I think you mispelled 'Turd.' You put 'Light Sail.' Kidding. Maybe it was magnetic and was affected by our magnetic field?
Ou' myyyy
ayy lmao
I had told some friends of mine I had a feeling, because of the orbit and reported shape, that it could be some kind of alien probe and I wish we had sent some kind of probe to intercept it or get picture of it. They all said I was crazy...
You just gotta love science.
This could be a very typical object in the universe. Given the size of our universe and what little we know about small anomalous objects this might be very ordinary. Still super fascinating though.
Entirely possible. As he says in the video he did write a paper calculating how many objects our solar system would lose or eject.
can anyone explain to me the process of which the astronomers used to determine the shape of oumuamua?
How about passing the bow shock accelerate things?
Intentional acceleration caused by directed thrust, which implies a repulsion system (engine by design).
It's RAMA!!!!! Lets 'rendezvous'...
In the movie Contact, we discovered an alien radio transmission with instructions on how to build a ship. Maybe Oumuamua was like this, but in physical form. A huge Willy Wonka golden ticket light sail cruising through the Milky Way, containing an invitation or some type of computer we could interact with. Similar to our golden record in Voyager, but far more advanced. OR... It was a test. And right now alien ships are amassing behind Jupiter after determining that Earth will be an easy target after failing to recognize their reconnaissance probe as a potential threat . "These Ehhhrrrth-lings will make a crunch snack and their planet will fuel our rockets for decades!"
Finally, someone with some common sense!
It was my impression from all the report I have seen that this object was long, thin and tumbling through space. If so then the light sail must be tumbling also and so the argument fails as the sail would have to be steady to be affect that much.
@speakupforjustice That still doesn't answer how a light sail could be attached to give drive in just o e dire toon if the object tumbles.
Damn I wish we could study it or be ready for the next
He is telling a story about his daughters like we don’t know about the philosophical argument of the rock and the watch...
We need to be able to see the earth / sun / moon pass by on a normal basis / our social structures should implement this concept
It is a giant space umbrella. Closed, it is long, cigar shaped. Open, walla, giant solar sail.
Ok so, there are a handful of events in our history that we can't explain completely. Examples are Oumuamua, the WOW signal, Tabby's star, and I'm sure others. What are the chances that we have missed identifying intelligent technologies outside of our solar system because we didn't have enough data? How many of these instances need to occur before we say wait a minute, something is trying to make its presence known?
