Auto upvoting every show you put out because they are awesome and though I don't agree with half the proposals the reality is this channel invites conversation, has great guests and hosts (And crew), and is just wonderful eye-candy as one falls asleep, this is a forever channel to sub to.
It is not if you agree with what is theorised but if you find it enjoyable. There are some I don't agree with myself but that does not stop them being entertaining.
The stuff between Neptune and A. Proxima is my favorite astronomical topic. I’m giddy! 😂
Fascinating episode! The idea of small interstellar objects flying around does sometimes make me feel like humanity is, metaphorically, trying to avoid really fast raindrops!
very well put
Hahahaha
beautiful
Really interesting conversation. Hopefully we hear more from these two when the Vera Rubin Observatory is operational.
Thanks, John!
That was a fun one. Do have them back when Rama and Sita show up.
Kugelblitz full of Heechee?
@Pax.Alotin awesome. Like Dr Strangelove
My first members perk , yay
Great sound mixing Ross! As always great guests and Great hosting team.
Eryn does the great job on the guests sound.
@@EventHorizonShow oh my fault, I thought Eryn helped you line up guests and provide the intro where I always say, “that person works for a very prestigious university.” I take it Ross as producer is doing your cuts and visual accompaniment then. You’re my favorite two channels on RUclips, so I try to imagine who handles the loads to make such great content on a regular basis.
Now THAT'S Rossy, he does all the interview booking. We'd be lost without him ^EK
@@EventHorizonShow I should have known Rossy has reached out to me before on the comments, makes sense to reach out to the big swingers on campus too. Guess I had your two roles reversed in my mind.
In the 1960's an astronomer who specialized in comets (prime discoverer of several) gave a talk I attended. He gave his definition of a comet -- verbatim to what I'd read in most astronomy books as the definition of an asteroid. During the question/answer period, I asked him what he thought the difference was. He smiled (as if thrilled to be asked) and then insisted asteroids and comets were two extremes of the exact same thing, with the same variations, and concentrating on their differences blinded us to their similarities. Since then, with our better telescopes, many more "in between" objects have been discovered..
Do you remember his name? Or what definition he gave?
@@avishalom2000lm The definition was verbatim the one used "The Music of the Spheres", at the time my favorite general astronomy, which I checked out from the city library numerous times & read cover to cover each time.
After just discovering a larger than average very long range comet, the professor gave talks at several universities, including MSU, Bozeman. where I met him. Wish I could remember his name It was about 50 years ago.
Would it be possible for you to make sure your guests record the audio in good quality?
Love your content!
Fantastic interview! Thanks for the episode!
Thank you for some excellent content!
What a great way to start my Friday morning : )
Great way to end my thursday
Man I wish I was a little older when Haley’s came by. I was awed by it, but my memory from that young is very faded. I also got to thinking about something wacky, a comment grenade. Highly sublimate able materials, with a dense shell. Heat radiates in, and bam, 💥 firework. This probably couldn’t work with natural formation physics as I understand it, but it would be really cool. Maybe we should make one!
John is there any way to get an uncut version of the Event Horizon theme song from the beginning of the show?
Link in the description for Miguel Johnson.
@@EventHorizonShow thank you!!! 💫🙏
@@EventHorizonShowthanks!
Thank you!
Thank you!
Hi John. My wife and I never miss an episode. Been with you since almost the beginning. This is my first comment and question. Do you think the Vera Rubin observatory will be able to see or identify objects that could be technological in nature? Maybe uap's in space? Keep loving your job John! We love your work.
Well, it would really depend on a few things. If the object accelerated and changed course, oh yeah, it'll see that. What else it might be able to determine is unclear, but what it can do is tell us such an object is coming. It'll catch them on their way in and give us the lead time to potentially catch it with a dedicated spacecraft.
I've done several shows with Professor Chandra Wickramasinghe on my channel about this topic . Much love !!!
Ah, just in time to fall asleep to. Thank you John!
deserves a million likes
Cool thanks for sharing. Enjoyed.
Not sure why I’m not getting notifications for these when they come up… I’m late but I’m here!
Thanks for a very interesting episode and guest, there's so much we don't know but we're getting there what an amazing universe we live in . Have a wonderful week people. PEACE AND LOVE TO EVERYONE ❤❤.
Love the channel !
Cool, another Event Horizon with John Michael 'thats a good question' Godier !
This is an important tool to find the dangerous asteroids.
Curious why you didn't ask about technosignatures -- a favorite theme of yours? Would the topic have made these guests uncomfortable?
Certain discovered paths would be the ultimate techno signature -- but let's not tell the funding source & jinx their future budgets.
@@friendlyone2706 re jinxing the budget, LOL; thanks for making me chuckle!
By paths, I assume you mean routes across the solar system...?
It isn't unlike you don't understand how science works in general, and you missed one of the detection methods in particular. When object moves in strange way, it will get picked straight away. Detecting first technostructure would probably grant Nobel prize, but you are taking about it like it was some conspiratorial mumbo jumbo or forbidden science. It isn't their objective, because it is extremely unlikely there is anything technological aside from our satellites and one car in the Solar System. It would be trivial for another civilization to hide spacecraft from such primitive methods anyway. There are materials that absorb 99.9% of light and they are practically invisible at night.
How am I supposed to fall asleep to 30 minute episodes 😩 .
I love these videos about the universe in which we Liiiiveee. Viva JMG
Thanks for sharing.
5 people I would like to invite to dinner…Moon Watcher, Leonardo da Vinci, Carl Sagan, Neil Young and John Michael Godier.
Thank you for every episode I love new ideas
Hell look, geez I would first like to know where the LLST is located, sorry I just don't know. Please someone inform. THANK YOU
I wonder if Borisov having CO means it likely formed around the much colder environment of a nearby red dwarf?
Fantastic interview, John! Thanks!!! 😃
Stay safe there with your family! 🖖😊
Safe? What danger is John and his family facing?
@@PetraKann the same we all are. It's a mad world nowadays, unfortunately...
@@MCsCreations
I see. So you are announcing a general danger warning in public?
And what preventative steps and precautions do you think everybody in the world should take?
298 mil inscritos, isso é um absurdo.
Great video and information !
Hail, JMG! 👏🏼🫡
I've been waiting foe some noise about the lsst it's going to be amazing. I thought that we would have a citizen science software package available which was suitably advanced to be able to assist the user and flag significant discoveries for further analysis by qualified astronomers
I'm impressed Hayabusa is going to meet up with a 15m object.
Could someone please tell me the name of the end credits music ?
Jmg please do the original intro. 🙏 falling into event horizon just isn't the same
Other universities besides Ivy League have astronomers too.
Woo
2:50 - Video starts
Thank me later
👏👏
So now we'll have to deal with trans-comets and trans-asteroids?
😮😮😮
Maybe ET is so clever he/she/it/ is so clever it could fling in a probe, to our solar system so deceptive it totally mimics a totally natural object? 😱👽
... RUclips doesn't allow me to stay subscribed to your channel.
What happens?
@@EventHorizonShow ...I click subscribe but every time I return or click on the video and then open again it says I'm not subscribed. It happens with few other channels as well. Though it is strange that I still get notifications occasionally.
Why on Earth are we fighting each other’s on Earth when we could get smash by one of these!l???
All bloody billion could be really used for good!
May be in another’s universe?
Not related to the topic, but have you yet have had courage to investigate why were all the so called death camps situated on soviet liberated territories? :)
