I'm getting old… when I was a kid I learned that this extinction event had happened 65 million years ago, and now it's 66 million 😕
You must be a million years old then 🤣
yea, 66 million. i was there but it wasn't an asteroid, my mother in law fell down. 🤣🤣
We got the same MIL 😂 @@crisespinoza1979
Covid made time pass exponentially, so maybe 🤷♂️ lol
Haha
You could say it killed many birds with one stone.
Too soon brother
But the birds survived
This made me laugh out loud
Get out
Cornball stew
I was there. It was soul-crushing, devastating, but somewhere deep down I felt relieved.
Truly a soul-shattering time for us all 😞
I was underground I was wondering what was all that noise above
A dark and hellish time for sure
😂
Cell service was abysmal xD
the impact of that asteroid was so massive that our minds can't even grasp what actually happened. We just cope with "yeah, everything went terribly wrong very quick" while recreating a couple minutes of animation to help us better visualize how it was back then
Kinda like when Captain Cook reached New Zealand for the first time, the natives had never seen anything like their ships and men of that color, weapons, clothing, etc, and it was so foreign to them that they did not even acknowledge them. It was so far out of their existence that they couldn't wrap their minds around what they were seeing.
@@kingjsolomonCaptain James Cook not captain hook 😅
I haven't personally experienced it. But I'm sure we understand how bad it would be.
im not low iq like you bud
If they're widespread enough and advanced enough it might be done by individuals or a small group without the knowledge of the rest of their civilization. Kind of like a poacher going into the wilderness to shoot an elephant
It's channels like this which is why I don't watch TV. Brilliant!
What are some similar high quality content channels?
Same. I also really like The Why Files. Give it a visit!
And then there's the 99% of memebot repost channels that make me go back to tv lol
@@J.Wolf90there is not a single thing worth watching on TV
@kipkipper-lg9vl I've been watching a show called resident alien but yeah nothing else really. I stream a lot of reruns
My head canon for this story is that the aliens got bored so they lobbed a big rock at the planet they were watching just to see what would happen, like a person playing Universe Sandbox.
They truly went Scorched Earth !
Too bad they didn't send the rock at 99.999999% the speed of light
the masculine urge
Can't inhabit the planet with the monsters they created still ruling it. Throw the rock at it. Wait... Inhabit the new world as human beings. I am obviously kidding but this idea would suggest that they were bored with the Dinosaurs. 💙✌️🤔😊
You people in this thread used to pull wings off of flies and torture rats with hacksaws when you were little.
The only thing that has changed for the dragonfly in the last 300 million years is their size. They used to be massive, but their structure and proportions are still exactly the same as their fossils. A system that wires their flight controls directly to their eyes doesn't need change. It's why they have the highest strike-kill ratio in all of earth's history. It's like their muscles can see the food in their airspace and instantly do the math required to eat it. Impressive that they made it through every catastrophic event over such a vast amount out time.
They're like the people who can see future events or fold space with their minds in Dune.
Yep, most oldest species can find protection in water, dragonflies can't.
And I assume that’s solely because of varying oxygen levels, being they’re insects I didn’t know they were so old 300 million wow how old is life half a billion years? Or is that complex life still incredible
Had to check not sure where I got half a billion from, complex life earliest evidence 1.5 billion, earliest mammal, only 210 million. This thing was flying around for 90 million years before our earliest ancestors had even taken shape
WRONG! Meganeura and relatives were NOT dragonflies (Odonata) but griffinflies in their own order!
I think it was both an asteroid AND volcanic activities. I watched a video (Demolition Ranch) where he shot a large solid glass ball with guns. One bullet hit the ball on the front, causing a nice crater. Then they noticed on the other side of the ball, exactly opposite the bullet crater, a small roughly circular area of cracks. The interveving areas of glass were unaffected. It was like a shock wave went around the glass and focused on the opposite side, magnifying their power to cause the cracking. I think the same thing happened to earth when the asteroid hit, causing the traps volcanism.
Huh, that's interesting! I have seen on another video, Atlaspro's video on Mars, about how the large martian volcanos line up with large craters on the opposite side of the planet. Hell Hawaii here on Earth lines up with a massive and ancient crater in Southern Africa. I wonder what volcanos were triggered by this impact, wonder if there's evidence of it too!
Similar to a head injury: the ‘contra-coup’ mechanism, where the brain opposite the insult is damaged. The antipodal effect is seen on the moon, Mars, and other bodies. Interesting
Spalling
This is shown on Mercury. I don't remember the names, but there's a big crater and at the antipode a mass of jumbled terrain.
You are describing the theory of antipode eruptions post impact. This is a common theory for a lot of impacts and one that was brought up with this one linking the Deccan traps together as the traps were pretty much on the opposite side at the time. However, there are basalt deposits from the Deccan traps that predate this impact. But another more prominent theory is that it was a double hit to life. It started with the enormous volume of greenhouse gasses expelling from the Deccan traps and then this impact. The meteor impacted in a shallow sea which had a thick floor of carbonate rock. The impact valorized a crazy amount of this carbonate rock and released massive amounts of CO2 into the atmosphere. Coupled with the months of fire raining down onto the surface and the years of nuclear winter afterwards, the final nails were hammered into the coffin for dinosaurs.
I strongly suspect these alien scientists would have known exactly that the event was going to occur and wouldn't have dared missed observing it either.
They saw it coming on their instrumentation and got the hell out of there
@@robertk1834 That would be silly. Much better to hang back at a safe distance and then direct every sensor their ship has at Earth to record the impact / aftermath.
For sure you - they - couldn't have slowed down to refuel at 24/7 Jupiter & completely failed to notice a bloody great rock less than one Terra rotation out & heading straight for it! 😕
@@antred11what do they need sensors for? They already know everything, and they've seen it more times than an Andy Griffeth rerun.... It's just entertainment, like a giant aquarium to them... No, no sensors...
Geordi tried to divert it but Q was nowhere to be found.
This is what the history channel should be
History, by definition, is about humans. So no, but this should be on National Geographic!
@@imgonnastealyourgirl wtf that’s completely false. By that definition the world or universe before humans is not history? You might need to look up the word again.
You need to look into the word again. History devoid of human story is not history. It's just geography. Astrophysics. @@rawimpact
@@ManishSingh-xo1fb no one said it isn’t a humans story. In fact that’s how I define history - knowledge from a humans perspective. We are able to go far before humans and write a story through other scientific means such as those you’ve mentioned.
I can't help but watch these videos with child like fascination. I keep catching my face striking these silly expressions that only stuff like this could manifest. Your worlds are a wonderful place to escape to, Alex.
Fascinating how much has been discovered about dinosaurs since I was a kid watching long necks wade in water pools in the land before time. Littlefoots moms death scene still hits me like an asteroid.
Awesome job as always Alex! While I am sad as a fan of dinosaurs it’s probably for the best because otherwise humanity wouldn’t have emerged as it has
I like the Arlo alternate history.
Theres only a few people who i can sit back and listen too, David Attenborough and you Alex. Most enjoyable thank you.
My 3 year old daughter is your biggest fan. She does not miss even single episode of yours.
😮
Excellent video Astrum as always and Alex I could listen to your dulcet tones allday! you're a fabulous narrator!
I LOVE This series, Alex! Can't wait for the next one!
What a great episode!
this was amazing, thanks for this!
Just love this…thank you so much.
Love this!
Fascinating video. Great content! Thank you!
I thank you for taking the time and effort to create educational works like this
Well done! Great episode!
Awesome videos as always say!!!!!
Most of the newest evidence says that the asteroid weakened the whole ecosystem but the volcanoes slowly chiped away at the dinosaurs for around 200k or even a million years before most of them became extinct, but there are still debates if the volcanoes were caused by the impact or if they were active well before it and it just happened for a huge metheorite to strike at that time.
i get so sad everytime i think about what the dinosaurs went thru, this is such an informative video.Thank you!
Great depiction and explanation of this huge extinction event.. 🙏
To be fair, if the aliens visited Earth the day before the asteroid impact then there is no way they would not have noticed said asteroid bearing down on the planet from only one day out.
It's a plot device 😂
@@astrumspaceasteroid could have been hidden behind the earth .only if they orbitted the earth theyd see it but if th stopped short of earth and the asteroid was coming from behind it theyd not see it.
Loved this. Thanks for making it.
I had no idea this series was going on! I'll go find the Playlist and watch from the beginning now
Props to the camera man for recording all this. Thats true dedication right there
i was there. im the camera man
Same,i was holding the boom mic 😎
Same, I was the camera 🎥
God speed
I was the other camera man
I was the earth 😂😂😂
4:48 human scientists lol.
😂
brilliant video. Thanks !
Love your videos, the font of your logo looks like a beauty brand
Every time i think of this event, i just feel deep sadness.
As hard as it is to find life it seems equally hard to get rid of it as well
Humans are incredibly resourceful-- I'm sure we can end all life if we stick with it
First time I've watched this channel. Impressed!
The thumbnail is... perfect! great piece of art
You should do when they come back in the future when humans go extinct and the Dolphins take over the land in perfect harmony
While that's a lovely idea, dolphins can actually be very cruel too. Sadly, I think any species intelligent enough to dominate the planet will be equally capable of being kind and cruel (just like us).
Goodbye and thanks for all the fish.
I'm in the Octopus camp- how many arms/legs does a dolphin have? An 8-fold octopus advantage right from the off.
Not dolphins, Poodles.
I feel sorry for the dinosaurs.
Don’t they in Dino heaven
phenomenal episode!
Thank you for these great videos
Why do I have the feeling this 18:44 long video took 5 minutes to watch? Time just flies by when I'm watching this channel. Well, at least I had fun! And learned a thing or two 👍
Megatron happened
Thanks, Alex! ☄
I was born in the Ford Galaxy, and I can promise my people won't harm humans, much.
It was a Monday. That's why the alien cadet did not hear the "beep beep" of the Big Bada Boom radar.
It all happened all of this time goes on and who knows what the future holds. I find these videos marvelous
I really hope the information in this video saves my life one day cause I definitely just skipped out on 18 minutes and 44 seconds of much needed sleep
Who's still watching 100 million year later?
Tidal wave 3,300 ft high... I'm no scientist but I think that is a wave 3x the height of the twin towers.
Astrum's videos about earth's past inspire me to reimagine 65 movie
God blessed you for your mission work and also our dear sister 🙏
Poor Aliens that had the ability to navigate the galaxy, but weren't able to detect local area asteroids.
it is understandable that they keep crash landing on Earth
Perhaps they did. Why would they care, though? Not their planet. And might not even have any such emotional capacity.
I mean, space is big... Really really big.
They sent the asteroid in order to experiment what would happen next 👽
@@mred8002 Or there was no detectable signs of higher levels of consciousness or civilization, so saw it as just a part of the process. Maybe all forms of intelligent life have, somewhere in their distant past, a period of hardship. Maybe a coddled world can't make something they deem their equal.
Only 66 million year old kids will understand 😭
I will like to see the life and animals and evolution of The whole Triassic period. - Thank you Astrum for exellent videos and stories.
As always I am enjoying the videos you provide. Interesting theory about our alien visitors surveying the earth.
Geese are still terrifying dinosaurs. Ask any Canadian.
So are chickens!
Well I will say this. I hope I’m not anywhere around when the super volcano 🌋 in Yellowstone Erupts. No joke
Great show!!
Props to the camera man for surviving all of this and giving us these great pictures
It was me btw, the rock ? Yep, my bad
Dino go boo boom
Thank you for the video.
Great Video! Snowball Earth would be interesting!
Some members of each type of surviving vertebrate animal now live (and may have then lived) in burrows or caves. Those environments would protect against the initial fires and overheated air which would wipe out other above ground dwellers.
The best place to see the iridium layer of the cretaceous-paleogene boundary is at the cliff of Stevns 40 km south of Copenhagen.
Thank you! I love it!🫠
Imagine seeing the ocean fill back the massive crater as the land mass it just hit burns in the background. What a fittingly badass end for a group of badass animals
Hang in there, dinosaur-kun!
talk about a bad day
Totally ruined my camping trip, had to hop back into my time pod and come home early!!!
Funny, I was just reading up on the KT extinction event for the first time in many years, and then you drop this. Perfect timing!
There's a lot of Star Trek novels out there, but there is one that I read last year called "First Frontier." The story is batshit crazy. In a nutshell, descendants of dinosaurs who were seeded on another planet and have since developed into intelligent and technologically-advanced species, travel to earth, go back in time and prevent the asteroid from hitting the planet, thus essentially erasing humanity from existing, and therefore, no Starfleet. Kirk and co. are in a temporal anomaly on the other side of the quadrant that is a direct result of the timeline being altered, and they survive the changes. They go back to earth, beam down to Starfleet headquarters, and all they see is a grassland area. They also encounter Vulcans and Klingons, but both races are vastly different than what they know them as. Kirk and his people end up having to go back in time to prevent the dinosaur people from averting the asteroid impact. One of the final scenes ends with them in orbit of earth as the asteroid makes impact. Just an absolutely crazy premise for a story, but if you're both a Star Trek fan and a dinosaurs enthusiast, you will love "First Frontier."
Another well done video! I always enjoy your videos.
Planetary-scale mega floods are a cool topic, like the Missoula and Bonneville floods, or the refilling of the Mediterranean sea.
Great video!! 👏👏 🌎
the problem with the flood basalt hypothesis is that it took several million years for the Siberian traps to cause the end-permian extinction, and it happened in several waves. By contrast, the K-Pg extinction happened almost instantaneously, pointing to a cause much more immediately catastrophic. It seems most likely that the Deccan traps were weakening ecosystems, and made the impact even more devastating than it would otherwise have been.
Can’t believe Alex is from Bridgend!! Thought the twang was familiar 😂
great video!
amazing video
thx - good educational show
You mean THX 📢😂
That was fascinating.
So great that parts 1 & 2 aren’t linked in the description and i have no idea what the narrator is referring to.
From the way it's described it seems impossible to imagine any living thing could have survived.
Iridium was widely used in the fountain pen making industry many years ago. Today it is one of the most expensive metals on the planet.
Yass bro that’s the most badass thumbnail
Please do part 4
As I live near by one of these ancient metior impact sites. I would like to search for some of this Iridium. Is there a metal detector that would locate or react to this element?
Thanks
AM I GOING CRAZY?? I swear there was a new Astrum video the other day about the possibility of life on other planets. The video was close to 2 hours long and I could have sworn Alex started the video saying something along the lines of "Im going to tell you everything I know about alien life". I decided to watch it later since it was such a long video and now I can't find it anywhere. I remember it being Astrum, but I'm scratching my head here.
Bookmark: save to a later date.
If you go on my channel and look at my recent videos, look for the one with "contact" on the thumbnail
@@astrumspace i see it now, I swear it disappeared for abperiod of time though. Thank you!
Damn you got me tearing up over dinosaurs dying
hmm lots of links in the description but can't find the first two parts you talked about at the start
More of these
I'm sure that next flyby they will be locking their doors and hitting a fuel stop in a better neighborhood.
When you look at most catastrophes its not one thing going wrong, its several. I personally beliove a metiorite and vulcanic activity caused the exstinction.
I'd love to visit the time when the earth was maybe something like Umbrial, just lost and lorn out there, a rock in space. And also when life started here. And then when life left the oceans. You're the best!! Thank you for all your hard work.
A breathless piece of cinematography narrated by the silky smooth tone of Alex. (I think that's how the bots do it?)
