Interstellar Visitors in the Oort Cloud with Amir Siraj
Вставка
- Опубліковано 20 чер 2024
- Amir Siraj is the director for interstellar object studies at the Galileo Project and is currently studying Astrophysics and Astronomy at Harvard University under Avi Loeb. One of his new papers, Breakup of a Long-Period Comet as the Origin of the Dinosaur Extinction, details how a comet is the most likely answer for what caused the dinosaur extinction.
Amir has also released papers on how the Oort cloud is likely full of interstellar objects. John discusses this and his take on why UAP and interstellar objects need to be studied.

Hello, how old is the host of the show?
@@ak.5620 Ancient. Older than the hills.
@@EventHorizonShow Lol
I make sure hit the Like on every video soon as notification comes in on both channels :)
@@randyfox364 Thank you!
Falling asleep listening to cool space stuff is part of my routine at this point. The timing couldn’t have been better.
Goodnight everyone! 😴
then technicaly we fall a sleep toghether in space timne ..lol
same's 👌🐱🏍
Happy to be in this club, sleep tight and enjoy your listen everyone
I envy you guys. Used to do the same but then UA-cam rolled update where they hid ads and made them unskippable. I don't have money to pay them £11 monthly and getting waken up from the podcasters amazingly calming voice by a loud annoying ad every ten minutes is a no no :(
🥱🛏😴💤 “yawn” same here. Then I listening full on the way to work.
this has kind of become the Thursday equivalent of a good night story for me, thx for you content man!
Our pleasure
I'd recommend the Event Horizon Playlists.
You never know what you will wake up to, and you DO learn while you sleep.
This stuff is a lot spookier than ghost stories
@@Kustan112 omg I've noticed this too! I've woken up with stuff I never knew in my head and its wild
Quran also describe science 1400 years ago that's sign that this Quran must be from God.
I searched for 'Amir Siraj' to find this episode and this channel again after listening late one night and the top results also included an Amir Siraj playing piano beautifully. Is this the same gentleman?
Yes it is.
I'm loving that these academics are starting to discuss the UAP report and topic regularly, that funded research has begun and that the ridicule and stigma is starting to be overcome.
Absolutely love this place. It’s like our brains are one.
Me: *Sees title* WHAT?!
Seriously, John, you and your team are rockstars..
Event Horizon is a bright spot every week for me. Thanks for another fantastic episode!
Hope you have recovered well!
LOVED LOVED LOVED the visuals on this episode. Amir is a great guest as always.
It would be so amazing if you could get Isaac Arthur, Dr. Avi Loeb, and Amir in either a debate or discussion panel regarding objects like oumuamua and/or the Fermi Paradox.
As always great content I love the channel
Debate is boring, dialectic is where interesting things happen.
I can never understand why this channel does not have a million subs already. Totally love this channel pls keep it going! Intently watched ads to support you
Thanks!
JMG, I can't put into words how happy I am to know about this project! Finally something like this!
Fantastic interview! Thanks a LOT! 😃
Stay safe there with your family! 🖖😊
I just wanted to thank you for such fantastic content, John. I work thirds, and Thursday night is my favorite night to look forward to, and not just because it's my Friday, but with you and Isaac Arthur, and a couple of other channels all releasing new content on Thursdays, it just makes my night so much more enjoyable. Thank you, and keep 'em coming!
Enjoy!
Yes!
Isaac Arthur owns the Drake equation!
God I love this channel. I would love to see a talk with someone who investigates survival of man on interplanetary travel.
This was a very good podcast! So fascinating to think about what might be in the oort cloud and outer solar system that we have no idea about yet!
There is a theory that the Younger Dryas event some 12k years ago was caused by multiple impacts of comet material from the Tauris meteor stream. This would indicate that such shrapnel events are very common and dangerous.
Nothing like a strong cup of joe and a JMG upload on a Thursday afternoon.
I'm so glad this channel exists ❤️
I love this channel. Thank you, brother. And really excited to find out what is out in the oort cloud
What a treat it is to love astronomy (or history, or the history of cinema, or... choose your topic) at a moment in time when a site like UA-cam has independent content creators who do it primarily for the love of it, respecting and challenging the audience's intelligence by delving deep, making use of guides and templates to deliver incredible content with professional production values AND minimal budgetary concerns.
As someone who has loved astronomy and actively pursued an in-depth understanding of it for decades, who has read books like "The Inflationary Universe" by Alan Guth, this is all beyond my wildest dreams, I have never been happier.
This is one of my favorite subjects, thank you for this great interview.
Man I'm excited to see Amir on EH again. While i love Isaac Arthurs' show, Event Horizon is much more engaging with the guests you bring on board. Thanks John.
You have best guests, the best interviews on UA-cam. Thank you, john.
Really nice interview, demonstrating once again how well you can unpack and create honest intellectual evaluations of near "system" phenomena that really do help the unpacking of the story of Planet earth in meaningful ways. Kudos to the both of you as thoughtful and intellectual human beings. Excellent discussion, excellent interview.
yezzzir literally just got done watching your video from last night about the first contact options
Please NEVER change the music. The absolute cherry on the top to this wonderful podcast that makes its audience look at the night sky with educated wonder and joy.
I love the idea of basic life forming on a moon of a rogue planet. No sunlight just tidal heating.
Very good guest and info. Thanks John.
This Oort to be interesting!
(I’ll get my coat…..)
This is good.
Oh man you crack me up 😂
Nice one John. This has been one of the best interviews you've done to date.
STUNNING INFORMATION ! MANY THANKS AMIR SIRAJ & HOST JOHN MICHAEL GODIER. FROM , U.K. (2023).
Another great conversation!
What would be an interesting follow up paper from Siraj & Loeb (regarding their three millenia estimate for a SETRI conversation with an ETI) would be to incorporate elements of the Silurian Hypothesis in their Bayesian prior probabilities--i.e., the assumption that ETIs were aware of human technosignatures well before our EM activity. Of course, the Silurian Hypothesis has a host of corollary assumptions--i.e., crypto terrestrial, Bracewell Probes, and so on, which would be difficult, if not impossible, to quantify over.
Nevertheless, l would interpret the 3 millennium estimate as a ceiling, or an upper bound. Same goes, btw, for the 10^6 yr estimate for expecting a return probe from SETRI endeavors. Siraj said it best: "assuming standard propulsion technology."
But there's no reason to assume an ETI eavesdropping on us is at our relatively rudimentary Kardashev Scale 0ish level.
Indeed, Prof. David Kipping in a recent Cool Worlds post summarized the details of an estimate his team at Cornell came up with, indicating that a very high likelihood that any ETI detecting Earthly technosignatures is far more technologically advanced than ours.
So in that regard, concerning means of propulsion, it's natural to speculate that probes (whether Von Neumann or otherwise) from such an ETI might be utilizing means to get from Point A to Point B in our Riemannian manifold in ways that manipulate for instate space-time-energy-matter-information on a Planck Scale, i.e., tinker around with the very quantum topological structure of the vacuum, thus long ago circumventing the usual c speed limits on the surface Riemannian manifold.
To us Earthlings, such "travel" would appear like "a violation of our known laws of physics" but obviously our "laws" are a product of and relative to, our best available conventional physics.
And even THEN, we could speculate further (a' la Michio Kaku) and conceive of an ETI so advanced that their physics they're working with might in principle be unknowable or beyond the limits of what we can even conceive is logically or metaphysically possible.
So again, the million year estimate (on the authors' part) for an expected return probe should, IMO, be viewed as an upper bound.
Excellent interview!
Has anyone else never seen or heard past the first 10 minutes? I love this stuff, but fall asleep every time.
Last time I was this early John had the right channel
Love these conversations!
Love waking up to a new video from you guys.
Damn I got an EH conversation and a JMG video to catch! Stoked!
You got fun times ahead. Next few weeks will be EXCITING.
@@EventHorizonShow woorrrdddd!!!!
Great video and information !
People always say that discovering aliens will change everything, but it's 2021. If aliens land tomorrow everybody will go, "so I guess THIS is happening now" and then just go back to what we were doing."
Me I'll geek over them, what's their tech, their physiology & culture. See us sci-fi nerds blow up the forums with fierce debates. 😆
Nice, time for my bed time story about space :-)
Enjoyed that... 😉
We all forget how vast the universe is.
Thumbnail is brilliant!
It shows how our solar system sails the ocean of space around milky way.
Wow!
We are so tiny like a spec of dust really going with it, because of its grace.
Particularly like this episode. Thanks, guys. :)
Love the show..Great guests ...and topics...TRULY TOP SHELF WORK...MUCH LUV FROM N.AUGUSTA S.C
Thank you Ken!
Great interview, thank you! Really interesting.
I have the hardest time believing that the ort cloud even exists! I just have a gut feeling that’s it isn’t there! Btw you do a great job on this channel and I have been a long time sub and really appreciate and enjoy your work! keep it up brother!!
Not only does it exist but new objects were recently just found. Over 400.
arxiv.org/abs/2109.03758
This episode was epic, on my 4th listen.
Awesome stuff. I’m so excited about future discoveries. I really wish I was one of those people who has seen a UAP. I’ve never seen anything but weather, airplanes and birds. I’m a skeptic… but I wish I wasn’t.
Last three videos from Pentagon are great, but rarely anyone does the math and all the information is on the screen, the speed, altitude, camera fov, etc. These are hundred percent mandane objects.
Super discussion.
would be interesting to know Amir's thoughts regarding the Younger Dryas impact hypothesis or clovis comet. That research has a lot of data and is going forward!
It is worth noting that the idea of the bolide causing the end cretaceous extinction is still being debated. It certainly must have played a part. But there have been other very large impacts, even during the late cretaceous that did not lead to anything approaching a mass extinction. So you also have to factor on rapid sea level drops, as well as changing ocean currents and the impact of the Deccan traps.
Great stuff as usual-so when's the next collab with Issac Arthur...and,can you invite Anton Petrov to join you for it ?
What a great Talk
awesome guys!
I've been subscribed for a while now and I rarely get a suggestion for your videos, I don't have on the notification bell Bc it's annoying.
But your channel is criminally under visited.
Isaac Arthur too , I just realized I haven't seen one of his videos in my feed in months
awesome episode and guest :D , ❤ the part at 40:00 minute mark, good luck w the UAP search !
Hope u had a nice Star Trek Day yesterday 🖖 , i chatted them to hire JMG . Akiva Goldsman + strange new worlds should be good
'intelligence' has developed more than once on THIS planet.
we are bound ro see more of it out there, eventually.
You've been watching Cool Worlds! : )
Thanks for opening my mind 🤓
Laying in bed with my headphones on, check my channels and boom. Perfect timing! Night night ya all!
Sleep well
Love your content
So... Universities need to write grants for six thousand years to adequately cover 2x the minimum time frame for discovery of a contact signal? I think this would be a good thing.. Funding archival storage and retrieval technologies might be a good idea as well.
Another JMG absolutelly entertaining video. I hope you win the lottery or w/e makes you happiest.
Thankyou for such wonderful, insightful discussions. I was wondering, is there an audio podcast on any platform? Really appreciate your great work.
Will be announcing a paid podcast option very soon.
How can UAP travel at fantastic speeds in the atmosphere without creating a sonic boom or leaving a plasma trail?
I hope the Galileo Project will take a page from wildlife science. Conduct surveys at randomly selected locations within potential "UAV habitat" to estimate the population density and test for patterns.
I'm getting better.Down to two seconds for the notification bell. 😎
Camper ;)
How do you think about the using of transit method to detect Trans neptune objects and Oort cloud comet? I think it's a good idea than direct imaging them
You sound like one of the members of the Caustic Soda podcast...
...
I approve.
Thank you for all the time and effort put on this, it is just amazing, thanks for all the videos, I go to sleep every night listening Event Horizon.
Event horizon is an apt channel name. I have not been able to get out of these videos.
Guys I'll figure this out. Just load me in a rocket with every episode of Event Horizon and blast me off toward the oort cloud.
Too true lets hope there is a seat for you on starship.
Art Bell would approve.
Insta like.
Great content.
Uap's are certainly real. We need more info for sure!
Good morning, John. ☕
Edit: Oh, god this is worrying. 🤔🤔 😬
At 22mins 10 secs what is the object making what appears to be a left turn ?
Fire baby! 💪
Uk's project Condign in the 90's came to the conclusion that UAP's are real phenomena that they call 'buoyant plasma formations'. The report suggested further research into 'novel military applications' and that Russia was working in this field and had understood the phenomena for some time and were particularly interested in 'plasma stealth'. Skip forward 25 years and the Russian SCRAMJET anti-ship hypersonic cruise missile 3M22 Zircon which is rumoured to use a form of plasma stealth is just finishing trials.
Planet 9 is a fun idea, but it was ruled out over 20 years ago when the one telescope with the anomalous readings showing another planetary body was shown to have had parts replaced shortly before the observations. When you remove that one telescope, every planet was where they were suppose to be and all planetary bodies are accounted for.
I listen once at night to fall asleep and then again the next day.
When Event Horizon started, I was sceptical if the concept would work.
I am so glad I was wrong!
I'm glad I was able to overcome my skepticism, too. I love this show and the thought-provoking discussions, even on subjects I have no interest in which are made intensely interesting!
What were you both most skeptical about?
@@EventHorizonShow The length of the videos and the focus on one person.
UA-cam is so distracting with its content (and thumbnails) and the typical "top ten something" is so much easier to consume compared to one hour of focus.
To manage to deliver - again and again - captivating content with this length is impressive.
I find your lack of faith disturbing! 😂
@@EventHorizonShow At the time, I thought that too much of a good thing wouldn't work out, but it did, and I am so glad for it.
I was at the hairdresser when the notification came in
Learned in high school: Astroids are rocky.
Learned in elementary: Comets make you vomit.
Slipknot: you cannot kill what you did not create!
Comets: hold my beer
So is a von neuman probe sending these comets towards Earth from the oort cloud?
So maybe the ort clouds are like a foreign exchange program for stars possibly bringing life from one system to another interesting I'm pretty sure every star has a similar field of debris
You probably wont see this but just to let you know: theres consistent issues with playing your episodes on google podcast. Dont know if it's the app or the feed
We aren’t on any podcast apps yet.
@@EventHorizonShow thats weird because i have been able to listen before on google pods. I hope someone's not stealing content? I'm looking forward to when u come to pod RSS. Keep doing your awesome job
I looked at all the options of stopping asteroids, comets or comet fragments and the options available to us are unviable both in terms in timescales for building for just in time deployment and cost. Quite worrying really.
Not really, options will become viable in next 100 years or so. We have bigger problems on Earth right now. There is no 10km impactor threatening the Earth in next 100 years. People misjudge the risk all the time.
Is this available in podcast form?
Will be very soon. There will be a paid podcast version with bonuses.
Looking forward to coffee!!!!!
Thank you J. Micheal Godier.
Grah! Interloper! 🙃
I'm late... But I'm now... FALLING INTO EVENT HORIZON!
I £()♡€ this channel. It reminds me a lot of a short wave radio rebroadcast of a college radio station science show they produced there. I would pick it up late into the Sunday AM back in the 1980s.
One show was on, "The Bootes Void - The Pacific Ocean Of The Cosmos". Another was if comet delivered viruses are alien in origin being neither animal or plant & their role in evolution.
Would anything make it through the Ort cloud?
Light does.
Falling into the event horizon armed with nothing but tea.
What kind?
@@oiocha5706 Some reliable Yorkshire tea, chap.
Hello! I remember you from O'Fallon!
Lloyd! How you been man?
52:47 talking about uap and there’s the head of some alien looking to the right in that cloud
My question is, if it is foreign adverserial then without a doubt we can expect the gov to swoop in and either put a stop to the search or filter out the good stuff.. Rule number 1 guys. Never let your enemy know what you know. Etc etc.
