A fresh JMG episode always makes the work night worth it....even if it is apocalyptic and horrifying 😂
Preach 🙏
Keep grindin! 🙏🏻

So true
I hit Like during the ad before the video
I recently watched Carl Sagan's "Cosmos" and I was totally surprised when I realized that in 1980 scientists had not discovered yet clues about the reason of dinosaurs' extinction. Who knows what other discoveries are waiting around the corner. Thank you for going on, John. Your creations are rays of photons during dark times.
It's incredible, how much science has figured out in our lifetimes.
It's only really since the 80s that most people had the opportunity to go to college, so we've had an explosion of research in them last 40 years, I think.
Calm down
Yeah, it's amazing how in my lifetime (I'm 24, for reference) I've seen consensus for how the Dinosaurs died out go from "We're not really sure" to "We're pretty sure it was an asteroid impact."
They suspected but didn't know about Chicxulub.
IIRC in the '80's we had the iridium layer at the K-T boundary and were just starting to get serious about finding the crater. (The Deccan Traps Vs Asteroid impact argument is STILL going)
I think if a massive meteor was going to hit, I’d just get as close to the “vaporization point” as possible and just enjoy the final show. 😂
In my country foreign TV shows are subtitled, not dubbed, so you if you know the original language you are sometimes treated to some real nuggets when the topic is outside the translators knowledge. Among my favorite mistranslations is an exchange from the 1995 low-budget sci-fi show "Space precinct", where in one episode they had discovered a large chunk (say a ton) of antimatter just laying about in the basement of a city building (yup you read that right, scripts and plot devices and stuff, just go with it) and first responders had secured the area and were discussing what to do next.
-"Shouldn't we evacuate?"
-"Nah, if this this blows, ground zero is the place to be."
Translation : "No, if this thing explodes, the safest place to be is on the ground floor."
Me: 🤔...😳🤦♂️🤦♂️😂🤣🤣
"Ground zero" didn't become a well-known term until September 2001.
Same lol
The best view would be from space.
A comfortable chair, a beverage and maybe a fancy hat!
I totally agree.... One Bright energetic flash and it's all over.. Because what will follow afterwards for those who are further away from the impact point will be a slow and painful death.
It's amazing that a meteor, so incredibly tiny compared to the surface area of the object it's hitting, can cause such devastating. It's like a flea killing a brontosaurus.
It is all that kinetic energy plus as Chicxulub has been identified as most likely being a large fragment of a tidally disrupted cometary nucleus it would have hit at incredible speeds in excess of 30km/s.
A more appropriate description would be a 50 cal antimaterial round killing an elephant.
Kinda like a bullet.
Or the tip of a spear, or the blade of a sword.
Large force, applied over a very tiny little pinpoint of surface area.
Absolutely REKT.
@@Dragrath1 how has it been identified as a cometary fragment.
A flea going hundreds of times faster than a bullet
Goes to show how delicate the balance of conditions that is necessary for life to be maintained on Earth.
I knew ground sloths were the avocado toast eating cappuccino drinking coastal elites.
You left off your Mom.
Man, never considered the idea of an artificial Earth-sourced object smacking into an asteroid and causing a mass extinction. Quite unfortunate the potential microbes on said asteroid's microbiome wouldn't understand the sublime irony of it
Please make a video on the (approximately 13,000 years ago) Younger Dryas impacts that created the Carolina bays, the Washington state scab lands, global flooding (which raised sea levels 400 feet) and wiping out 90 percent of the mega fauna, which included Mammoths and Saber tooth Tigers. Thanks.
Randall Carlson is wrong about the scab lands. While there was an asteroid impact in Greenland that corresponds to the Younger Dryas; the scab lands in WA were caused by flooding from glacial lake Missoula.
Was going to post this myself, it's a lot more relatable catastrophe, I think. 65 million years ago, compared to almost recent human history, kind of thing. Gobekli Tepe, e.g. Antonio Zamora here on youtube has done some great videos with calculations of energy per projectile, flight time from the impact site at Saginaw Bay, and lidar images showing the absolute carpet bombing that happened there.
mega-fauna may actually have been driven to extinction by Homo sapiens.
@@zachjones6944 carlson will be proven right in the end
Except Mammoths persisted much later and evidence of their existence as late as 5,000 years ago in mainland Siberia was recently found. This is the not the first time this happened either. There's been quite a few times where groups of animals persisted later than the fossil record originally suggested.
If an asteroid ever does hit Earth I hope it hits my house.
Straight up!
Same here. I don’t want to be around after.
🤣🤣😂
I hope it hits your house too. ))
I hope you live next to Biden.
We need more 20-30 min videos from you. I absolutely love astronomy, early earth history, extinction events etc.
It's been days since you last posted on this channel. I've gotten spoiled over these past few months. I've been checking your JMG channel daily for 4 or 5 days now for new content. Glad to see you posted something tonight! 😊
Or you could just activate notifications and the checking does itself. Just a suggestion 👍
@@birbdad1842 true. And they are active for JMG.
BUT.... for JMG content I go by the "trust but verify" method.
I trust that youtube will notify me, but I need to verify for myself to see if JMG has uploaded new content! 🤣😂🤣
It's true. 😂
Thanks for the suggestion though. 😊
This is why we need to work toward running our cities as if they were huge self sufficient space ships sitting on the surface of Earth.
I was just thinking, it is stupid we don't work together as a species to harden our species against extinction. Instead, we threaten each other with it.
Then run for Mayor of your city using that platform. You will go far, I'm sure.

@@ElectronFieldPulse 99% of humanity's problems are caused by the 1% who are born psychopaths. I am hoping they have the right brain scans and genetic screening in place to ensure than none of them make it to Mars. But then Mars would face the threat of psychopaths from Earth attacking them in the further future. Sounds like a good theme for a Science Fiction series...
@@ElectronFieldPulse
Right!!!!?????
It's mind boggling to me!
Just be kind!
Seems so out of reach for most ppl..
🤦
Star Trek voyager had a episode where the crew ran into a advanced species(evolved from dinosaurs) that left earth after that meteor hit and its tech was so far more advanced than Starfleets. It was a very interesting episode
Put the bottle down son.....
@@0scartheCat s03e23 Distant Origin
My dad was a WWII vet who loved Science fiction. He always thought we got here on earth by accident and didn’t think we belonged on this planet. Part of his theory was that there was a war between aliens and one side threw asteroids at earth. Somehow a few aliens survived the bombardment and injected monkeys with their DNA. He was a great storyteller and your videos remind me of him. Thank you.
Imagine if there were other human species in space. Or something
Yay! Thank you for immediately acknowledging that birds are dinosaurs.
Even an icy asteroid could/would be devastating to a modern civilization if it hit the right place. Barely any trace of the meteor remained on the ground, yet it had the power of a nuclear weapon. Just think if the Tunguska asteroid had hit a major European city instead of Siberia.
JMG: 'Something caused the extinction of the dinosaurs"
Avi Loeb: "Ancient Aliens"
I think this might be my favorite channel on the whole youtube, love the topic and your narration style is perfect. Many of these channels gloss over things too quickly, they are exited about the subject but there is no time to reflect and connect the dots. You take the time to carefully and precisely explain things with a great overall view, perfect.
Try watching 'Fall Of Civilisations' channel.
You can tell just from the comments on his videos how good it is.
It is my, and many others, favourite channel on here and is brilliant, it is a better quality than anyything that is out there on any TV platform worldwide, amazing channel.
Very good episode. It has been a stressful day and this made a very good bedtime story. Thank you.
PS - I liked your book.
John I already know this will be an amazing video!!
You sir ALWAYS deliver!
You have gotten me thru some tough times with your humor yet educational content..
Standing ovation from me!
~ Sending love from the

Another awesome upload JMG! Thank you for everything!
Thank you for another intriguing episode JMG. I always look forward to seeing the notification of a new video.
Interesting as usual
@John Michael Godier , your statement at the beginning of the episode that dinosaurs were already in a decline is very controversial. Many paleontologists will say that they weren't in decline, and that their numbers and variety remained healthy.
I’m about to listen to this video and fall asleep. Found your channel in December and feel like I should thank you for being my go to channel to fall asleep to. This is easily my favorite currently active channel on this platform.
Great episode John I love that you're making longer videos now! Thanks, hope you're doing well. :)
I can't wait to see what type of content he starts to create after he watches David LaPoint's UA-cam video called " The Primer Fields " . Because, as soon as he sees why Saturn's hexagon is there, he'll be absolutely hooked on Plasma Cosmology. Electromagnetism rules the universe, NOT gravity.
Been waiting for a new video! Thanks JMG!
Always a highlight to see a new vid pop up. Thank you.
I'm new to this channel. I've only seen a few episodes with this one being my fourth. Great content, very informal and scientific. Thank you for all the time and effort put into your videos!
Welcome to the planet on which we liiive. 👍❤️
John Michael Godier, you know so much about space and time, just keep on doing it bro!
I have a meteorite from the Barringer Crater or what we call it in AZ Meteor Crater. It’s about the size of a large egg and is all iron. The owners of the property find them when they go out and search the property with metal detectors.
“On average we’re not overdue for another 100 million year asteroid anytime soon.” Me has flashbacks of missing several 90% in xcom.
Nicely presented and quality audio, thanks!
ah a winter video, very seasonal! all ready for some ash-man building
😂😂😂
I must be tired cuz it took me a millisecond to get it.. 😄
Good one 😉
Excelente video John. Gracias por divulgar ciencia a traves de este medio.
I rarely learn anything now. That’s 2 videos in a row where I have learned something. What a great feeling. 🙏🏻👍🏻
Love your videos man, always appreciate the uploads!
i ran an RPG capaign years ago, where sentient dinosaurs, flleing an iridium weapon war, travelled uptime, and the PCs had to stop their incursions
Excellent as always good sir! Keep ‘em coming
Love your videos man.
I finally ordered your book from Amazon. Can't wait!
"Extinction through vaporization" should be a band.
At 40 minutes since upload this video has more views than seconds it's been available. You're awesome JMG
I take a trip to the Yucatán peninsula every summer to visit family, and I’m now realizing after walking that land, how big that meteorite truly was, it’s incredible
Really great video! I've seen many videos about impact winter and impact catastrophes, and given its length of only 21min, this is one of the most informative ones I've seen on the topic of what the effects were and would be. Keep it up.
Oh, and sure your voice would be great to fall asleep to, if only you wouldn't keep saying such interesting and thought-provoking things that keep my brain running in the dark...
Thank you for another addition to the spooky playlist :)
Not a new story. It has been told many times. But in the way jmg does it, it's awesome. Thanks again jmg! I follow your channel for countless years now, i like it and it feels like we all know you.
The apparent decline in dinosaur species before the K-Pg extinction event is as far as I know still speculative.
The amount of diverse and specialized species right around this time speaks against it.
was listening to this while I made breakfast and accidentally turned the heat up too high. had to restart it so I could pay better attention after I almost turned one side of my sausages into charcoal while the rest would have been raw. you are that relaxing and that interesting.
It is said that we have experienced four smaller events and is shown in Mesoamerica, Egypt, and is depicted in the St. Peter's Basilica as the Delphic Sibyl with four babies holding up the sky. A great book on the subject is The Cosmic Winter by Victor Clube and Bill Napier 1990.
That was excellent and very entertaining, you just earned a new subscriber, thankyou for making a lousy day a lot better
“Earned” a new subscriber. Wow thanks for gracing him with your excellence.
A fun fact about meteorites and mythology: the ancient Egyptians believed the sky was made of iron because it had the same color as highly polished iron, could withstand the heat of the sun, and occasionally dropped bits of iron to the earth as meteorites.
The damage a bullet does to a glass ball could explain what we see on earth.
The impact side broke off in a big layer which could explain the age of the Pacific plate, while the shockwaves travelled around the planet and met creating another crater on the opposite side which resembles the Himalayas or the ring of fire
One of the more recent hypotheses about Chixulub still being debated by scientists is that it kicked up such a huge amount of debris that the collective kinetic and frictional energy of all that material reentering Earth's atmosphere at the same time heated it to broiling temperature during the worst of that Very Bad Day.
It's not as far-fetched as it sounds: witnesses to both Tunguska and Chelyabinsk reported feeling heat, as well as the air blast. And each of those was only ONE object, not thousands..
Atmosphere temporarily heated to broiling explains hints in the fossil record that all the world's plants caught fire- afterwards there's a period when there's only fern spores, as if everything else was toast. And it explains the oft-repeated claim that no paleontologist has ever discovered any dinosaurs above the iridium line except for birds. And for that matter it seems like nothing larger than a chicken survived aboveground (I read one paper claiming that the birds that made it through were burrowers, although I'm not sure whether that's true. Certainly the mammals were.)
TL;DR: add one more nasty possibility to your arsenal of potential asteroid impact hazards: large strikes may be able to loft enough debris to set off a secondary meteor shower which, if it has enough kinetic heat, could raise atmospheric temps to dangerous levels for several hours during the first day of catastrophe. Not yet proven, but I have seen it mentioned in enough NOVA type documentaries and articles on Livescience, Discover, etc that it seems ro be a legit theory (in the layperson's use of the word).
Really awesome video, JMG! Thanks! 😃
And well... I'm happy that there's already a mission to try to change the orbit of an asteroid... It's at least a start!
Anyway, stay safe there with your family! 🖖😊
nuking it still seems the best solution
Great vid! Thanks
I totally hope that I can get your books read with your voice, your voice helps me soo much. It makes me feel calm and it helps me go to sleep better than any pills I have been prescribed. God bless your voice and its calming effects
Humans at Kardashev 1.0:
"Ohhh, asteroid? Cool. More metals!"
JMG is back at it baby with another banger! Turn it up! Turn it up! Turn it up! 🔥💪🔊
When I was younger I used to enjoy watching meteor showers, now I hold my breath a little during peak days.
I’m literally your biggest fan dude
13:00
This sounds like the planetary equivalent of a story that you'd get beers over.
"Geez dude, what happened to your planet?"
"Well, it was the darndest thing."
Love it
It has happened before. It will happen again. The only question is when?
Tomorrow.
Don’t look up
This is excellent at giving a solid high school level view of the K-T event. If you're interested but have a short attention span (like me) you might have noticed that because he enunciates so clearly, his speech rate is sometimes slower than other similar UA-cam videos. At 1.15x playback the pace is much better and still allows total absorption of information.
Great video
Absolutely _brilliant_ work as always John!!! The music levels were a little low though--that ethereal synth is a real signature of your channel and helps the story-telling no end. I missed it quite a bit.
Looking forward to the next entry.
I agree personally but I think it strikes a balance between those who prefer to have the music and those who don't
Dumbass comment
I thought the music levels were a little high. His voice is the best music.
Too LOUD if anything.
@@DanCooper404 Didn't he say he was going to release two versions of his material in future--one that had a backing track and one that didn't?
Best channel on UA-cam
This really cheered me up 🤔😂
Calm yourself.
“How do we restart civilization?”
Kind of you to assume it started in the first place.🤠
I came across and report recently about a new study of past mass extinctions and impact events. In it, the researchers claim that winters from even very large impactors did not by themselves cause mass extinctions. The mass extinctions happened specifically in cases were albedo-lowering sediments were pulverized in large amount. These led to the impact winter being immediately followed by sudden warming of the climate which in combination overwhelmed the ability of ecosystems to recover, triggering a mass extinctions.
Conversely after impact events where no such sediments were thrown up in large quantities, the environment was able to recover from the impact winter without a mass extinction, despite some of these impactors being larger than the ones that did cause mass extinctions.
The article did not mention whether factors like acid rain were taken into account, though even if they were not, the relevation that large impacts have occurred without triggering mass extinctions would be significant.
"Bird! Don't you call me no friggin' bird!", said the cassowary, as it disemboweled you with it's medial claw.
Nice video.
As to your last question about the dinosaurs, there was an interesting episode of Star Trek: Voyager regarding that deals with it.
Hate to tell ya that it’s absolute bullshit. Cmon. You’re talking about Star Trek? Ridiculous.
what's the name of the episode?
@@jjbeatle2006 Distant Origin
We made it to another year and still no Asteroid. So I have te chance to write a happy new year to one of my most favorite voices on the internets. You‘ll also rock 24! ✊
Fascinating video series. You mentioned briefly that, if there were advanced civilizations in the Earth's remote past, like intelligent dinosaurs or thecodonts, there might be no record of them, or we could easily miss it. I'd be really interested to hear you expand on that possibility in a future video.
Never been here this early! Niiiiice
Listening to this while watching meteors and jupiter love this challenge
Good luck on that!
Just boosting this legends algorythm
Thank - You .
If we had a perfect simulator or iunno, Futurama's "What if?" machine, how long it'd take for dinosaurs to evolve from having brains the size of a walnut to a human equivalent brain. Also, since dinosaurs were reptiles, can a cold-blooded species even become intelligent?
Things discussed in a single JMG video:
1. Dinosaurs
2. Spark plugs
3. Thomas Jefferson
4. Iron rain
5. Avocados
6. Vampire bats
7. Mars
You won’t find an equally eclectic variety of topics anywhere else.
I did not know birds as we know them existed alongside dinosaurs.
Not as we know them...
They are that shit we see flying in the skies.
Nice.
Well, given the fact that dinos had about 150-200 million years to develop intelligence, and still failed, and mammals took only about that 66 million years to develop from a prehistoric mouse to us, it's not clear that dinos would've ever evolved into an intelligent spieces. I'd like to think they would have, but the numbers don't lie.
Well birds are immensely intelligent, I wonder if the surviving the KT extinction selected for intelligence in some species.
Maybe they did, multiple times? How would we know?
Ahh yea! JMG all the way! 💪
Excellent video. Can’t wait for more James web videos as well. 👍🏻
Bought a Tektite teardrop last year.. it is one of the most awe inspiring objects I've ever held
JMG when are we getting an audiobook of Supermind?
1:27 so your trying to tell me T-rex tastes like chicken?

I'm about to finish your book "The Salvagers" and I've been enjoying it! There's definitely a hint of realism that immerses me, though I'm no physicist.
The only minor criticism I can make is dialogue and characters. It's not bad by any means, but it's not something I'll be quoting. Regardless, the world is so well-crafted that it's a minor nuisance!
Thumbs for John's new video and then ill watch it👍
19:00. That'd be a chad move. Like mugging the mugger. Ah, humanity...
Very informative and logical
Probably the most dramatic solution to global warming.
Could you even say...earth shattering solution!?
Impact Winter, Volcanic Winter and Nuclear Winter are no joke! Good things is, two of those can be actively prevented.
The South Pacific volcano explosion gave us an insight into what might happen with an asteroid impact on earth. Multiple shockwaves around the world for hours. Tidal waves that would sweep over continents. Dust and fire filled atmosphere for weeks.
16:42 There's a problem with this take: WE have driven the megafauna to extinction. Had we not done that, avocado wouldn't be endangered.
