Вставка
- Опубліковано 14 лис 2018
- John Michael Godier spoke to Dr. Karen Meech, who leads the Astrobiology research team at the University of Hawaii which discovered the first interstellar object, named 'Oumuamua, by the Pan-STARRS 1 telescope. Dr. Meech's team recently led the characterization to determine the size, shape, color and light curve of this first interstellar visitor from afar - 'Oumuamua.

it’s odd that science seems to always give spectacular anomaly very odd names
i believe it is an attempt to quell interest and discussion
No. Unless it's a broken one! Lol
I'm not sure what to make of this thing yet?
@@bigtravis1968 Id say its more due to the culture of science. Outside of the categorical identifiers, the less formal names are often nods to the people and places associated their their discovery. I like that about science - there's an air of respect between scientists regardless of their field of study 🤗
No one has ever seen anything like Oumuamua? I don't think so...
An eminent NASA scientist named Dr Norman Bergrun -- a popular mechanical engineer -- has revealed about spotting alien spaceships around planets like the gas-giant Saturn and Jupiter.
Images of these UFOs have been captured by the Voyager space probe too. These crafts are cylindrical or cigar-shaped which are miles long.

This is quickly becoming my favourite channel.
@KGB How did you get to that conclusion?
@KGB I'm high bro don't listen to me.
@KGB true
Agree. Quality content in which the host interviews a proper scientist and expert on the subject instead of all those other vids made by loonies that do their half-assed research off Wikipedia.
This is excellent!

Great episode and a lot of new info on Oumuamua. I love the music and graphics you choose for your episodes John. Thanks again for bringing such awesome programming to us each week.
Best episode so far, fantastic stuff. Thanks for taking the time to make it.
You are most welcome!
Thank you for the follow up. Great interview. Plus I enjoyed how your speaker explains things in a way I can wrap my head around. Thank you
Great interview, I look forward to every new episode, thanks for doing these.
I'm always impressed with the quality of the guests on this show.
I'm so glad I've discovered your channel some time ago, these interviews are gold for someone like me, passionate about space.
Enjoy! Being passionate about space myself, I really love conducting these interviews.
This show has become essential listening while I work at home on Saturdays.
I'm so glad I stumbled onto this channel thanks to the Isaac Arthur's interview. It's very good. This has been the best video I've seen regarding 'Oumuamua yet. You get some very good people to interview man. I don't know how you find them all.
Well I've been watching solely youtube for at least 3 years now and I've never been so blown away by a channel. This man knows how my brain works and asks the same questions I would. Marvelous stuff.
JMG, your videos are great.
I'm certain I've watched all of them, all the way through.
thank you for your time and effort; really quality content.
edit - and wow! what a fascinating conversation. incredibly thought provoking.
Great interview and I love the focus of the channel in the past few weeks on oumuamua - the in-depth interviews with the people publishing on the topic was quite helpful in understanding the literature in a different field than my own. Thanks John.
You are most welcome! We'll cover 'Oumuamua whenever something new comes up.
good trend of interviewing the scientists in news 👍
I could listen to Dr Meech and you talk all day. So many fascinating questions and answers
Came from Isaac Arthur. Now a proud subscriber. Very excited to find this hidden gem of a channel.
Learning alot, great interview, thank u Dr Meech and event horizon team
Dune, did you suggest Dr. Meech? If so thank you! Great suggestion.
@@EventHorizonShow Glad i did, the interview was great
Just a little congrats to your channel😉 five months today the 18th! Thanks for bringing great content to us!
Another incredible video. If we get to witness an interstellar object every year, I'd be one happy camper. That'd be like a second Christmas for me.
Wow. I love the new intro! Another great one! My aerospace engineer friends also enjoy what you do as well!
Wonderful talk and questions! Dr. Meech is a very bright lady.
Great interview! Great choice of interviews subject! Thank you.
Awesome and informative. Going to subscribe just because this video was so good!
thanks for the update.
So good to hear from you John Michael Godier. I love your new channel .
Ooo mummy daddy
Great interview!
I found this absolutely amazing, so many unknowns out there!
Wow I love this so much! Keep it up.
This is a great stuff, thanks John :)
I love your channel and I know it’s going to take off in a big way, I would be amazed if you don’t have way more then 100k subs before you hit your first year mark, please keep it going. Your insight on fascinating subjects is brilliant 😘
Thanks!
I really enjoyed this. Real science, without a lot of BS and speculation. Dr. Meech was the perfect astrophysicist to interview about this object. She had the experience and data to support her claims. Well done.
Thanks doctor,it was a pleasure
Would love to hear Dr. Meech's comments on necessary engineering advances and investments it would take to be prepared to properly study the NEXT interstellar visitor.
We would need to start working on nuclear rockets again, unfortunately we have become paranoid about its use.
This is no laughing matter as an impact would prove man's insignificance to this Universe. Personally I see now why people get religious --- fear of the unknown. Without faith that SOMETHING or SOMEONE will prevent impact, we'd all be Chicken Littles carrying signs that read "The End Is Near".
@@CandidDate Man is insignificant relative to the size of the universe but our potential is at least just as great.
Eddie I like that!
We really need to get up into space. If we can get to mars maybe we will get better knowledge of whats out there.
I think I've said this before, but this channel is better than anything on cable TV.
Another fantastic interview John. I love just listening to these while I explore Space Engine.
Awesome! Love the content👍 Not the usual clickbaiting from unreliable sources like the most UA-cam channels.
one of the best channels around .
The name of the Interstellar visitor is quite cool - it rhymes well with a bunch of words and sounds like it can be incorporated into songs. Songs that will make astronomy cool. 😊
Great interview by the way, mostly enjoyable, thanks for the effort, Jon!
Excellent! Very interesting.
Yeeeessss! Got tests tomorrow so this is the perfect distraction! Thank you JMG and the team! 😁😁
Edit: and thanks to Dr. Karen Meech!
How did those tests go?
Thank you, Dr. Meech.
Hi Sunshine, so interesting with so many possibilities, not unlike the story of our lives always watch out for the next one, this is what keeps the Drive alive...
I love the song in the intro!!
Thank you for wonderful job you are doing. Oumuamua is fascinating subject to expand human understanding and imagination.
Reminds me of the black monolith from 2001
I love these videos :)
A very good episode. Many unanswered or unknowable questions. Mystery - I love it!

Liked before watching, thanks John.
not only the guest the host was very helpful to understand better the things that surround Oumuamua
Leaving a comment to make this video more favored in the eyes of Google's algorithms and will continue to do so on every video
Cool & Clear infos here !👍
looking forward to the info on this asteroid would love to see us do more on these objects
Is it a Space Ship camouflaged as a rock?
Thanks for an intelligent interview with an extraordinarily
I like the LIGHT SAIL hypotheses!!! :)
Awesome stuff as usual. Can I suggest foregoing the preview next time? I didn’t want to watch it for fear of spoiling the full episode and it was just a total tease!
Expect the unexpected forever n ever my friend!💐
this topic about oumuamua never gets old and boring, thank you John!
I think we'll continue to hear more about Oumuamua for months to come.
Would it be possible to keep "spare" spacecraft ready for launch when the next interstellar object is detected? Very enjoyable video. Cutting-edge and relevant, as always.
Not a new topic but a follow up. Thanks to all involved
Thank you for this Wonderful presentation discovered because of my keen interest in Oumuamua. I enjoyed the questions, the beautiful graphics, and Dr. Meech's clear explanations of the phenomenon. (I still think it could be alien!) 😉
Glad you enjoyed it!
Spectacular channel.
I thought the object was at rest (according to Loeb), and we crashed into it...no?
Would love to hear you discussing the recently released Tic Tac, Go Fast, Gimbal videos with someone smart.
Hey john when are you and mister Isaac Arthur gonna collaborate on this topic would be awesome I think
Whats most interesting is the very same who knew nothing about this object one day are the very same who claim to know everything about it the very next day! Intelligent life remains humble!
It's a space snow board. You can do mean tricks on it.
But really though. I am fascinated by this.
its "lit" as the kids say
Good host btw!
If this came from outside the solar system then it wouldn’t have tumbled through interstellar space. My guess is it occurred when it passed through the Oort Cloud or the speed it was travelling at and then interacting with the suns gravity may have put it into a tumble. Either way since no astronomers know definitively what it is conclusively, then the only known factor is that this is definitely classified as an unknown flying object.
Interesting times ahead
Stunning images......Space is deep.......
Impressive explanations from Karen Meech. To be fantastical, If Oumuamua is a spaceship "lookalike hamster wheel" with an invisible outer structure then could the suggestion of a constant tumbling motion indicate that this motion was creating artificial gravity for its occupants? Could you calculate the size/gravity of its home planet from the rate of tumbling?
Have you been able to study it in it's egress?
Yeah do that, chat to Isaac Arthur for decades I'll listen for sure
I liked her. Hope she comes back in the future
I love the amount of details and info we got on the first observed object from out of our solar system! I mean not even a single photo! Well done modern day scientist! Well done! She even sounds proud of the lack of information they got! Well done!
Finally good sound from the guest. 21st century at last!
A relic of the ancient history of a distant world. (Greetings)
the fact that omumua is shaped like a big turd is a message in of itself
What an incredible journey this messenger from afar must’ve been on to stumble into our little planetary neighborhood. I hope we can catch up with it, or at the very least; we catch up with whatever interstellar object that comes next.
Contato.. magnífico muito bom mesmo parabéns.🙏🇧🇷🇧🇷🇧🇷
It's really terrifying when you realise the possibility of it. Even though it's not probable, it's awe-striking. The thought of an alien fly-by.
damn good show
Pancake shape? Kind of like a saucer... Maybe a flying saucer? I swear life is an ironic comedy lmao
John Michael Godier could sell paint and make it sound interesting. This is an awesome channel!
if only he didn't stumble over his questions quite so much. very interesting nonetheless.
I'm not saying it's aliens, but it's aliens.
My money's on space pickles. There should be a gigantic pastrami sandwich coming our way soon.
Frank Mazzur probably aliens dildo
I recorded something the other night that wasn't aliens but it was aliens
lolol
Frank Mazzur yep I believe it
Let’s send a probe to intersect it and know definitively one way or another.
Edit: get probes ready so we can send when/if we see another.
I feel as technology gets better these will be easier to find
Oumuamua is going way too fast for any man made probe to reach it.
the next one should be named "Rama".
Fake news ! Or it's God's turd. Yeah I went there...UR-ANUS !
I agree we have to have probe ready for immediately use for the events like this one!
A Rendevous with Rama. I love that book. Great name for the next interstellar visitor (Rama).
So the acceleration of oumoumua remains an unsolved mystery
Can we backwards calculate its trajectory and speed and try to figure out where it came from? I realize that distant light is an image of the past. But we should be able to figure for that too if the speed of light is known and constant. The calculations are immense and tough but if we have supercomputers, one would think we'd fix that too.
Course, I realize that it also depends on how many times a celestial object like a comet or asteroid has also been nicked or hit or influenced by other things. So it would be fairly difficult to deduce its true history. The incomprehensibly gargantuan distances of space makes that very difficult.
Wonder if Oumuamua's rotation is enough to create life sustainable gravity at either end of the object?
Great. Now I'm seeing this in my suggestions. Thanks for the heads up, UA-cam. I'll start building my rocket now.
Fun. I think this one must have gotten buried in my watch later list.
The YT suggested content algorithm hasn't got a clue what to do with me. For half the day all I search for and watch is electronics stuff, except occasionally while eating lunch. Then I'm all about edutainment in the evening. They wind up showing me tons of technical suggestions in the evening, and goofy stuff in the morning.
I should probably make a few private playlists just for catching up on stuff like this, but they would get lost in all my others...hopeless.
...anyways...thanks for the reminder about this one Ross. I got my weekly EH fix still ;)

I immediately thought of Rendezvous with Rama....Kinda wish it had been named Rama
In Dr. Meech's Ted Talk she mentions that the team gave it the name Rama at first until it was named Oumuamua.
@@EventHorizonShow That's awesome! The universal language of Arthur C. Clarke :-)
@tommysil As in Rendezvous with Rama by A. C. Clarke
Some astronomers didn't like the name 'oumuamua (refusing to attempt to pronounce anything that starts with an apostrophe) but they wouldn't say Rama as they're boring. Or scared of being tarred with aliens ;)
Well if there's 2 more...
Given enough time, could carbon compounds based on fullerenes in a stellar nursery form sheet or layered structures that might be rigid enough to survive violent dynamic ejection and acquire tholins? The list of elements and compounds that could comprise Oumouamoua doesn't seem to be that large. Carbon, silicon, iron or ices.
Another aspect of this, is that they probably have a technology that can reduce their volume while retaining the same mass. This would include the occupants as well - so that the entire vehicle and its occupants remain in scale, yet are reduced in physical dimension. This would enable a very large craft to become smaller in relation to interstellar particulate matter, and thus move faster because of reduced drag. The fact that it has been observed to be long and narrow would reinforce speculation that it is a craft designed to transit interstellar space.
6:58 Ah-ha! Thanks for asking about that albedo detail, John. :)
...and 30:05 for the shape.
I love to hear about this subject!
I hope Breakthrough Starshot can chase after 'Oumuamua when it comes online. I want a real image of it! :-)
Did you hear that Tom Delong ? Hurry the fuck up!
zapfanzapfan
That stuff sounds like alchemy
Depends if we divide to go that direction
@BentFox videos exactly
hey yo, how do you choose the next topic of your video? I would love to see something about futurism and dystopias, but if this is strictly about physics and astrology, then we still good. Your channel tho 10/10 keep it up. Best of vibes for you 🔥.
What if we use the Drake Equation to figure out how many interstellar probe's there could be, we would need to add, 5 for the number of probes we have sent so far, then a percentage of those civilizations that are space faring say 50%, then a number for how long that civilization is space faring. There very well be hundreds if not thousands of probes.
Is it faceted? It reminds me of a schist sample I saw in geology 101. Could it be metamorphic? 🤷 Is discontinuity evident in the galaxy oruniverse as is evident on earth?
The end over end is for artificial gravity , and did you see the window shades were pulled down !
Another great topic! I'd almost foolishly suggest the topic of Europa and other potentially life compatible worlds, even though enough has been said. I'd just infinitely soak in that topic even if it just means words were reordered in same sentences across it..
1:16 The first such object we've detected? What if more are following? The idea has been popping into my head about this being the tip of a bunch of debris coming from somewhere. But it could just as easily not be either. Who knows.
Yeah Issac Arthur conversations are always going to be long and filled with things. My brother is an Aerospace Engineer, we talk till we fall asleep, My love for boats had him living on one for over a year, It's never a slow moment when the world is out there looking to chat with you about trees and ants.
