Your work helps us become better humans. Your presentations are important, digestible, & fun. Keep em coming, sir.
Hell yeah.
Well said brother 👏
I couldn't relate more.
I am LOVING this string of recent uploads. Makes my entire day seeing a new video and they’re always so interesting. Keep it going! You’re my favorite UA-camr
John is on a roll!
@@Top_Weeb On a roll baby! 🙌
I listen every night, don't comment often.
Just wanted to say I really appreciate how much content you been dropping lately. Thank you❤️
If the Dinosaurs received a warning by passing aliens, they must have dismissed it as a...Fossil Arm.
10:35 "...or even a fragment of concrete...could pave the way." Well played.
When I look at a coin that was made before the year I was born, it blows my mind thinking of how this little coin has been floating around the entire time I’ve known time, if that makes sense. Staring at the rock that’s been around before our sun 🤯
In addition to the Vera Rubin observatory the proliferation of phone and security cameras is allowing a lot more asteroids entering the atmosphere to be captured, and their velocities/orbits calculated by analyzing the footage. It’s safe to assume we will eventually find much more interstellar junk dropping in occasionally as time goes on.
Absolutely. I saw that first hand a few years ago. I heard a loud detonation outside. Turned out to be a meteorite fall, but a whole bunch of security cameras caught it.
@@JohnMichaelGodier if it exploded in the atmosphere it was a meteriod, not a meteorite.
@@JohnMichaelGodier Id like to experience that one day myself.... Of course i don't want the meteorite to hit an an animal or God forbid a person though.
@@threehead99 only if nothing hit the ground. That is an unknown.
I love having both short and focused videos here, and deeper discussions on Event Horizon. There's certainly no shortage of fascinating topics to explore!
Honestly, if this isnt a simulation then we really are some of the luckiest people that will ever live.
I have lived through the transition from analogue to digital. Seen the first exoplanets discovered, the higgs boson confirmed, the creation of the internet and am likely to see the first person on another planet.
What a time to be alive.
One can always find reasons to keep on living^^ I think it might be an advanced or strange form of simulation and differ from our view of this term
I share your sentiment completely, i winner what other technologies and services will developers in the next 50 to 60 years
I love you JMG .. You always teach me so much ... Can u do one on the recent solar flares that have been happening?
I love ur work
Your amazing
You ain't seen nothin yet Andrea !
King of the Space Videos! Fine work as always JMG!
I'm so glad you're posting more often, love Event Horizon though but love a good JMG video
Straight on it JMG I appreciate your work so much and regard it very highly thank you so so much. Oh I have seen a production about asteroids and meteorites in our solar system . On the video they actually point out that some material they have found that has fallen to earth is stuff from another hypernova/ supernova covered in the material from our stars left over beginnings. I realise even we have atoms of hydrogen in the water we drink that obviously has to come from the quark plasma that came forth from the creation of our universe so it isnt a stretch we find these elements from other star systems rolling around with the dust and rocks in our own system .
We are all made of stars ⭐️⭐️⭐️❤️❤️❤️
@John Michael Godier thank you for never criticizing Avi Loeb. Too many other people on UA-cam laugh at him, some you've had on your show. But you've always been professional and showed respect. Its too bad people don't understand he's a thinker
I just separate the science from the person. Sure we can question results, that's expected. But ad hominem, no I won't engage in that. I happen to like Dr. Loeb, have known him for years, and I'll take a proper open minded look at anything he presents. I'd challenge anyone to take on his black hole work and I'd love to see more rebuttals of Loeb's work with Oumamua and the spherules in the proper scientific literature where it belongs. But youtube, media and twitter scientist fights? Bad form.
I just read about this meteorite, so cool!
Man I love all of your videos, but I really
love a couple and this is one! Thanks JMG
The best mimicry for an advanced, but physically vulnerable life form would to be look exactly like nature we see around us. Looking like one of billions of floating rocks, would be smart for a scout.
I've gotta tell you that Im a huge fan and love your content. I watch it constantly before I go to bed. The excellent compositions of your work, the interesting topics and all of the research makes for such a great experience. Definitely have fell asleep multiple times with your playlists running man and I appreciate all you hard work. Keep it up! The more the merrier I say because I get excited when I see new posts from you! Cheers!!!!
An earthquake hit Papua New Guinea the Wednesday, January 8, 2014 at 17:16 with a magnitude of 4.4. The closest city with more than 15.000 habitants is Port Moresby (Papua New Guinea - PG). The epicenter is located at longitude 166.4747 and latitude -12.7526. 2138.82 km from Ovalle.
That’s very interesting. A bit more info: the meteor was detected entering Earth’s atmosphere at 17:05:34 UTC. Loeb’s paper estimated the meteor’s velocity to be at least 46 kilometers per second. A Scientific American article written by Amir Siraj states that the speed could have been at an even faster 60 kilometers per second. I wonder how fast it was going when it impacted the ocean off the coast of PNG.
finding fossils from another world never crossed my mind thats interesting asf love ur stuff bro keep it up
Just got back home from work, really looking forward to falling asleep to this content 🙌😇
I do have to wonder if the first reaction upon realizing that we'd found an Earth rock after spending all that money to go to the Moon was, "ah, hell no."
Listening to John is always fascinating and calming.
Finally, new content for decent sleep )
This is an important field. Considering how heavy elements are created in stars and spread out in supernova explosions the type of star they originated from must effect what elemnts are created and in what quantities. As such there just may come an interstellar object our way absolutely loaded with something that only exist as trace elements in our own star system. That just may create an interplanetary gold fever absolutely all Klondike tropes we can come up with!
Great video JMG
You're uploading a ton these days. Thank you
Perfect timing. Was just about to head to bed. Thanks john 💪🏾
Absolutely love listening to your shows.
John thank you so much for providing me with the best sleep of my life these past couple weeks with the boatload of content!
JMG is simply on a roll! Keep it going! 🙌
Man! I hadn't been to your channel in a bit but I come back and you're still you. You NEVER come across as preachy or boring, and I really appreciate knowing you are out there, making videos about space. I genuinely wish you the best in your life
Yo I'm finally early, love your videos Man.
I went away for a week over Easter and came back to find not one, but two new videos! Thanks, John!
Gonna be another one prolly on Thursday.
I love your channel so much.
You are the absolute GREATEST
Love all the recent, quality content.
Brilliant John, fascinating video. Thank you.
"That's right; there could very well be material from another star system sitting on the ocean floor near Manus Island off the coast of Papua New Guinea."
Somewhere, the ghost of H. P. Lovecraft is shrieking in terror.
woo! we're living in the JMG lots of uploads times!
Great episode as always
Awesome video as always
Makes me wonder what amazing things lay at the bottom of the oceans...perhaps never to be seen. Maybe even a piece of some faraway planet containing a fossilized complex life form inside of it.
That would explain Cuttlefish.....LOL!!!
For me, that's a stretch. But that's also the beauty of it, never being able to be 100% certain.
That could very well be possible, jelly fish could be aliens that came to the Ocean by an asteroid from far away and evolved to live on Earth, they don't share any similarities to any animal in the world, they are aliens basically by biology...
Terrific stuff! What a lightning bolt it would be to humanity to find an alien fossil!👾☄🌌👽🚀🔭
I love the way you think and feel John. Your stuff is so absolutely fascinating, I just have to tell you, I appreciate your narration and production of each of these amazing segments. It's more amazing to travel the universe on your Channel, then too ride the Enterprise with Spock!
Love you JMG!
I like your channel, John. It's been a couple years for me and here's why. You make us ponder circumstances well beyond our corporeal realm. You give us food for thought about a much greater scheme than our meager and petty struggles here on Earth. Not to diminish our problems, but it is cathartic to just sit back for 15 minutes and escape our microcosm. It's a pleasant perspective. Cheers mate.
Amazing!
Astro paleontology. Astro archeology and interstellar geology. Love it!
Bro I literally do a fist pump when I open UA-cam and I see you dropped a new video
Astro-paleontology gets me really excited!
I love this channel ❣️
Fantastic video, JMG! Thanks a lot! 😃
Great research!!!
Stay safe there with your family! 🖖😊
Is it bad that I'm proud that this is the first topic I read about AND nerded out about before John posted the video
That ending live was long enough, but I know you can go longer. 👍
Time to launch the Lebaron into the interstellar medium. Thanks for the video, John!
Utterly facinating possibilities.
Maybe we could launch a mission to rendezvous with an asteroid from another solar system and then maybe grab a sample or two.
With the amount of genuine interest you have for the topics of your creative craft, you are one of the few UA-camrs I can really say has quality AND quantity on their side. You keep the interest flowing with every new video and every new subscriber. Please keep em coming :)
Your videos never disappoint
I love me some JMG! You make my day bro.
Such a good informative channel.
Though the thought that we may not get to travel to any planet further then Mars is not just depressing but also puts the scale of our galaxy and the universe as a whole in to perspective
Awesome really 🙂
Well, we just have to get launch costs lowered and faster propulsion systems and our whole solar system would be accessible!

i could see us eventually being able to travel our solar system, but other star systems might just be science fiction. who knows though
Recently, I saw a card (probably misspelled) on Cracked stating that the steel knife in King Tut's tomb (long known to made from a meteorite) could not possibly have been made by the Egyptians.
My scientific question: Why does Cracked suck so much now?
Seriously, this seems like a physics question at this point.
Why do so many things that used to not suck...now suck really hard?
I remember them not sucking...and yet now they suck really bad.
Why?
Eagerly awaiting the Ted Talk on this subject.
Technically, they're correct.
The people of that region in King Tuts time did not call themselves Egyptian. Nor did anyone else.
This reminds me of an old episode of "Men Into Space". An asteroid is found bearing pterosaur-like fossils. Naturally, the writers were thinking in terms of the lost planet theory of asteroids back then, but interstellar debris could have been the culprit just as easily. It's still unsettling to think that a planet with advanced life could be devastated or destroyed by an impact of such magnitude. I guess I'm showing my age in all this, huh?!
Read an article about this earlier today. Other scientists are in robust disagreement that it is a proven interstellar object. They could be fighting about this for years.
If your books are half as good as these videos, then I have to read them!
Every single one of your videos will have upwards of one million views in ten years.
If both panspermia AND interstellar meteors are a thing, perhaps earth has been seeded from another solar system? And if umoamoa was a probe, perhaps it was also spreading seeds in our system?
Good shit Johnny boy
The surface and subsurface of the Moon is an archive of what has happened in the solar system for the past 4 billion years. May we soon read a lot more of its books! 🙂
Alternate title:
A coming-of-age asteroid story on Earth and its interstellar geology.
Excellent! 💚💜💕
I just wish I could take a spacewalk, but ain't happening for me this lifetime so watching your videos would do for now, thank you! :)
You never know. The cost of launching things into orbit could come down enough for widespread civilian space travel to become possible within existing lifetimes.
Bleh, I get dizzy just thinking about it. I would definitely stay inside, at least if there was more coffee left.
It is, indeed, a fascinating universe in which we liiiiiiiiiiiivve. 😎
Thanx man, I rather enjoy your work
Did you just predict the "Dino Wars?"
Favorite sign off so far
love your videos! your voice is so calming as well lol
If we had a beacon that could last thousands of years do you think we could attach it to the next interstellar visitor and see where it goes?
Power is the problem. With sufficient technology to self-repair, you could put devices on the objects and track them long term like we do wildlife. The problem though would be in the power source since you couldn't use solar. Best we have right now are RTG's, but they only last on the order of decades. Now you could tag passing stars pretty easily because they emit their own energy to power the device.
Hey John, we can neither confirm nor deny these asteroids because if we're seeing them then they must have been on earth for a long long time as you have taught me already
"We are all made of starstuff."
~~Carl Sagan 🌎☄️✨
This just proves him correct......
🌌🔭
Yes that is true but the stars are made out of universe stuff from the big bang and the universe is well no one has looked yet.
Just knowing the list of minerals contained in the human body is proof. The Periodic Table is the icing on the entire cake. Of the 90 chemical elements found in nature, only 19 of them are known to occur as minerals.
Ok... what still doesn't make sense to me... why does the speed at which the meteorite hit mean it came from interstellar space?
Could it not have sped up due to gravity assist?
Could it not have an elongated orbit similar to how we've seen stars orbiting black holes? It speeds up as orbit gets grabbed by gravity and then slows down while exiting?
Hopefully my question makes sense
What's up John
Oh nothing. Just dropping a video. You?
I always wait for the end.
I guess from your opening that you've watched Dr. Kipping's new video on FTL being almost certainly impossible. Would love to hear your take on it.
My great grandchildren might be able to visit Mars when they’re my age. That would be cool. But, that’s the ribably about all we’ll have in the realms of space travel. Unless we figure out a way to instantly teleport across distances you cannot quantify or comprehend in miles or even AU…
For some reason people don't know about the 1 realistic method for interstellar travel. If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 ship/7.3 Earth years (and that includes turning the ship around halfway and decelerating) and it would have gravity the whole way. The ship would achieve about
.95 light speed after about 1 year.
All that's needed for this is a true fission rocket (not nuclear thermal) that can put out thrust for long periods and does not consume hydrogen or xenon (you can't bring 500 tons of that with you. A 10 ton ship would need a mere 10 tons of continuous thrust.
I believe there is a way to get uranium or plutonium to fission in a linear fashion with an electrical current. 1kg of uranium has the same energy as 120,000 tons of coal and plutonium has more than that. The trip to Alpha Centauri would require less than 1 pound of uranium.
With this method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 years.
For more info on the constant 1g acceleration method watch "best method for interstellar travel", it's also on Wikipedia.
If aliens ever visited here millions of years ago I really hope they have pictures of dinosaurs. Image receiving an alien message from space along with a dino pic.
Interesting and funny post. I can envision a future alien sitcom with aliens sharing vacation pics of the time they visited earth.
We may soon be able to build spaceships capable of travelling at 0.2c to the nearest stars.
Robotic construction of megastructures, thermonuclear fusion engines and high power space based lasers may all be possible in the near future. We currently use 1/7000 of the solar energy received by Earth which in turn is 1/500,000,000 of the total solar output.
I'm not sure if it's the frequency of interstellar objects increasing, or our observations of them, but it's the former, and the theory that Oumuamua was a part of a planet... I fear what may be coming behind it.
Dude im just not afraid to die anymore.. and thatd be enough if dying didnt hurt
Love your video's. Bas
Thanks for making my breakfast more interesting .
Update: portions of Theia theorized inside earth detected by subsurface scans. A huge amount has been found, possibly explaining the areas of modified gravity. A large portion of our planet is understood to be of interstellar origin!
Hank Green is almost positive there is a dinosaur tooth on the moon 🦷🌕
If meteorites have randomly distributed orbits, then there should be more of them at higher energies at dawn than at dusk thanks to Earth's 30 km/s orbital velocity
John, any new Stoner Rock finds?
I've been digging back in time for protostoner rock, specifically in super early Jethro Tull performances before they got huge. At times they almost sound like a precursor to Tool, but in the late 60's.

I love jethrow and tool lol
There is a small chance of finding a mocha Frappuccino if the planet being blasted has as many Starbucks as we do.
Talks of a beacon and dinosaur analogues is giving me heavy r/repitliandude vibes. Regardless, this is another great and informative vid!
I think that like Exo Planets or Gravitational waves we'll find that interstellar visitors are a bit too common to remain comfortable. Same goes for finding basic life forms such as Exo-Algae. Once we find Algae enough times we'll have the required push to find intelligent life, and once we do find it we'll then quickly find it everywhere.
Maybe humanity will become the equivlant of the world's largest yarn ball for interstellar tourist to gawk at while they fill up fuel at our neighborhood's star.
More please!
More videos on Kardyshev scale please!
I'm not sure that Mars is within our grasp as far as human visitors are concerned.The problems seem,at the moment, pretty challenging.
