Earth (2023)
Discover the astonishing four-billion-year story of the place we call home, told over five dramatic episodes. This revealing biography of Earth explores the planet's most epic moments. From the first raindrops that turned it into a water world to the arrival of its most incredible inhabitants, us. But humans take a back seat in this narrative. Instead, Earth is placed centre stage. We see what happened to our world before we even crawled from the mud - including massive bombardments from space, extreme changes in climate and the collision of whole continents. The series uses the trademark dramatic storytelling techniques of The Planets to bring this unique story of creation to life.

Talk about a bad day...
Don’t let a bad day bring you down
Wow can’t wait til we get this DLC, the graphics look amazing 😂
Yes indeed!

Это хороший день для человечества, ведь если бы не вымерли динозавры, млекопитающие вряд ли получили бы шанс захватить сушу
Dinosaurs boss: “so you’re still coming in today, though, right?”
Not the mama
It's frightening that we are so helpless even it happens today
Don't believe this BS.
@@salesprosteveAre you seriously denying the KT Mass Extinction? 💀
NASA's DART. That's our defense.
Wtf@@salesprosteve
Only a Space Force equivalent to Star Trek would save us from
a 6 mile wide space rock. Probably up to 100 years away.
These visuals have no business looking so stunning
Impresionantes? Se quedan bastante cortas si pones en perspectiva como se vería un impacto así en la vida real
"If the dinosaurs had had a space program, they would still be here today..." Carl Sagan
Well we have one,and we absolutly cant repel a 6 miles asteroid lmao,not yet anyway
@@kalidah8431 thats what you think...
@@xafar67 im listening
@@kalidah8431 you show me the six mile wide asteroid first...
@@xafar67 huh....what?
The dinosaurs must have been terrified 😢
i just thought about this a few minutes ago. they must’ve been so confused :(
It's disturbing to think that this awesome animation (and most asteroid impact depictions) is still very watered down compared to reality, since if you were anywhere in line of sight, you would be vaporized immediately, before it even struck the ground.
Those who were vaporized were the lucky ones.
It really is actually mind blowing to think about the earth shattering level of destruction it would cause.
On the other hand its incredible to think of what would have happened if the asteroid didn`t hit the earth? The reign of the dinosaurs lasted over 150 million years before the impact- would they still be here today if the asteroid had missed?
Avian dinosaur descendants are still thriving today so no reason to think they wouldn't, but we can surely say, that none of us would be here. Though it might be like the old Super Mario Bros. movie timeline instead, lol. @@freddiemehrcurry428
@@freddiemehrcurry428interesting question, when you hear stories of dragons one must ask oneself were they dragons or were they dinosaurs as back then the word dinosaur didn’t exist so I put to you that there’s a temple in Cambodia where they have dinosaurs carved out of stone in which temples were made so there’s that.
Impressive how even after that, the earth still grew back alive
It’s nowhere near the worst mass extinction event. The Permian or great dying killed over 90% of all life over half a million years. This was before the dinosaurs.
even if the moon smashed into earth the planet would still survive and eventually support life again. which has already happened once before
Allah is the greatest
@@Bbreezy1337 i dont know about that, everyone that praising allah in middle east r always at war and fighting and getting killed
I always said that to how was the earth suppose to grow back after that happens it's nuts
animation is getting better each year.maybe one day we will see a precise rendition of the event that kill all the dinosaurs
Not sure we could claim it being precise without ever being there, but the graphics are nice
@@ibewillI think he meant being able to calculate nearly everything about that asteroid and then with that data simulate what it would look like.
Precise yet not accurate
you will see it first person
Finally, Now that's what I'm talking about, they really nailed the accurate depiction of explosion of the impact in both ground level view and in space view rather than a stereotypical mushroom cloud we always see in many asteroid impact documentaries, hope other documentaries will learn about the impact explosion dynamics from them in the future
I think it would be far more bright and impossible to see with naked eye by that distance. But I agree, it's a better simulation than others.
Agreed👍
3:15 Looks almost like the Death Star hitting the desert planet in Rogue One
03:14 is equally breathtakingly stunning as it is inherently frightening.
the vfx team clearly copied the death star jedha scene from rogue one.
3:01 shout out to the cameraman that gave his life for this shot. Lost, but never forgotten.
😂😂
cameraman never dies hahahaha
😂😂 he is a legend Rip camera man
Imagine the awesome species lost during the impact leaving no history to be discovered
Bear in mind that the dinosaur fossil record only reveals about 5% of the species alive during the dinosaur age. Think about that.
Poor little dinosaurs. They had no idea what was going on. Just scared and in pain.
I would litrely love to see a dinosaur in real life even though I mite be eating a minute later it would still be cool but a no one would be able to survive with them here but it would be cool to see one with my own eyes walking about
i cried
Poor dinos 🥺💔
Lol 😂
Crying a river or oceans 🌊
THE ICE AGE!!
*shoots ice laser*
Amazingly, you can still see its impact and damage even today.
Amazingly you're more gullible than the rest of the viewers.
How?😊
@@larskk101Chicxulub Crater
Not visibly. It's buried several thousand feet.
The asteroid was likely a faster death for the dinosaurs as an extinction was pending anyways. If you look through the geological timeline there was a period of massive volcanic active before and after the impact. The Deccan traps formed on the moving indian plate and had already induced climate change, a similar effect to the Permian Triassic extinction. Its possible that without the volcanic activity the asteroid may not have wiped out the dinosaurs. The deccan traps is undermined by the asteriod but recent work suggests that the volcanic activity played a major role in the K-Pg event
It's now thought that the impact caused the deccan traps to erupt.
03:05 damn that's some good animation. Looks epic!
Nice graphics, seriously. I watched the impact scenes from the ground perspective and space perspective several times.
Poor dinosaurs ; they didn't see it coming. What a way to go.
The VFX is insane….
Without asteroid-chan's help, man wouldn't have existed
Can't help but feel sorry for the Dinosaurs 🦕
It makes me so sad 😞
I hate being right every time
Wow the graphics are insane! Props to the vfx team
Asteroid: (Heads toward Earth)
Dinosaurs: "OMG!!! We must protect the economy!!!"
🦕🦖
This video was EXCELLENT 👍👍👍 Thank you👍
Sephiroth got tired of their shit is all…
Interesting information
I want a full video on this
The explosion shown in this video is lot better with more clarity than the Oppenheimer hype
CGI vs Reality Comparing here
what is the name of this episode and where can i watch it
Cool animation!
bro looks at a pond and says "oh yeah thats the thing that killed everything"
This is impressive, would like to see the place where the asteroid fell.
Once dinosaurs wiped out ! now Humans ! then who will be next !! Once happens that means it can happen again !! really scary to imagine what will happen in future !!
यह घटना एक प्राचीन भारतीय ग्रंथों में वर्णित एक कहावत को चरितार्थ करती है कि "विनाश से ही उत्पति का सृजन होता है" क्योंकि उस महाविनाश के बाद धरती पर मनुष्य का सृजन हुआ।
And one hit about 12500 years ago and another will come from the asteroid belt that passes our planet twice a year in June and October
Fun fact: the trains in Japan still arrived on time the day the asteroid struck. Incredible.
Never use the word "fact" on a joke,dumbfuck
Source?
When the asteroid first contacted earth, part of it was still in space.
Ah not impressed
Hello! Where can I see this full documentary?? @bbc
Did you ever find it?
@@Its_A_London_Thing no , let me know if you do!
I certainly hope you don't think I had anything to do with it!
About time someone did a realistic representation
I remember as a kid in the late 1950's reading that no one knew why they suddenly and mysteriously disappeared. Still can't wrap my head around today's birds being their descendants and maybe some dinosaurs had feathers and were brightly colored! There is so much we still don’t know about our planet’s past.
3:29 we can even here some dino cries
I would too if I and everything around me were being barbecued alive by lava rain, lol
I wonder why it happened! It changed whole world completely
The asteroid was sent by alien civilization from another solar system so that they can get rid of dinosaurs to pave the way for human civilization.
became colder, thus destroying eco-system.
looks like someone superimposed the death star destruction scene from rogue one and touched it up a bit to not catch any attention.
except i did. you also wouldn't have even seen a rock or a trail as it happens in 2:40. it would have simply been pulses of blinding light followed by a white out event until the resulting fireball and cloud had formed
It shows how the VFX team artist at rogue one did a great job of accurately depicting what exactly it should look like.
how do humans know this but there was no human when that tragedy happend🤨🤨🤨🤨🤨🤨🤨
Ever heard of geology??
wow
Assumptions, as no one was present
These aren't assumptions.
When it happens again .... Can we now stop or deflect it.... Or do we just watch and die ?
🪼 jellyfish actually survived this crazy event and other deep sea dwellers
My grandpa farted after eating cabbage.
They didn't stand a chance...
this "Hit" was more devastating due to the angle at which it entered the atmosphere and subsequently hit
Explain
@rgudduu it hit at 60 degrees which scientists call the deadliest angle because climate changing gases would be thrust into the atmosphere
@@simonhealey9253 hmmm maybe right
And also the material of the bedrock at the impact site. Created acid rain.
@@simonhealey9253none of it is fact they are all theories. No one will know exactly what happened.
If people don't know this by now I'd be amazed. How many more documentaries are going to be made about this?? Not to mention that he didn't even mention the real reason we understand where and what hit because of the iridium deposits in the soil layers.
It's just someone's point of view... Nobody was around to witness it lol.
@@salesprosteveit’s not a pov it’s working theory. The best one yet.
Not only are there people that don't know this but there are people that don't even realize that dinosaurs are extinct. Not kidding, worked with one.
You worked with someone that thought they were still alive or thought that they never existed?@@supertuber120
How about that extraordinary claim of millions of years?
Not extraordinary at all. It is based on geochronology by radiometric dating.
But let me guess, you’re a Bible thumper, aren’t you?
Day of Lavos
shoutout to the camera man
Read Steve Brusette's book: The Rise and Fall of the Dinosaurs. Excellent book!
This needs to happen in the jurassic world series to make things right
i wish dinosaurs never went extinct
2:28
Eggs vs live birth and suckling? Live birth would eventually win.
it must have seemed like the last day on Earth for them.
I'm with Larson, smoking killed the Dino's.
Pop quiz....
Which day was worse?
A The last day of the dinosaurs
B The last hemroid you had
C Jan 20th, 2020, 12:01pm
A moon of saturn was destroyed, debris from said event hit earth, 65 million years ago. Not a coincidence.
The smoking gun was the shocked quartz that was found during a drilling operation.
That's a lot of sinotays...
If an asteroid of this magnitude hit earth today would be a catastrophic event and costly at that every nation in the world would take years to recover if they survived
Long story short, we would all be died.
Thank you for enlightening us all with the knowledge that an extinction level asteroid impact would be “catastrophic and costly” if it happened today.
Crazy roaches can survive this, but die instantly with Raid lol
We live on earth.
Then why other species survived?
Buried underground or in water
Food chain all but gone Apex predators goodbye Vienna! Clear some life survive and thank goodness or we may never had become what we are today! All these pathetic religious clowns can go pray in the corner and do nothing for our species while science figures out a way to prevent it doing it to us! You want fiction go to a church or mosque you want truth, facts and rescue put you faith in Science baby!❤✌
And in air.
Right. Ground dwelling animals had a chance, protected underground, and gave rise to mammalian supremacy.@@_MaZTeR_
“Other”
All species survived in one way or another. Even the dinosaurs. But mammals did better.
Did the fire rain travel across the globe? Just wondering why it killed ALL the dinosaurs but not all life
It wasn`t the fire rain that wiped out the dinosaurs.
The asteroid strike vapourised the gypsum on the sea floor causing it to be ejected into the atmosphere as an aerosol. This blocked out the sun for several years causing photosynthesis in plants to become highly reduced. It also caused the oceans to become acidified in turn triggering catastrophic changes to the world`s climate.
The plant eating dinosaurs couldn`t adapt to the shock on the global ecosystem resulting in the carnivorous dinosaurs that fed on them also perishing.
The effect on the dinosaurs is most noticeable because they were the most widely dispersed large creatures on the planet but the KT strike in fact wiped out 75% of all life on Earth including mammals, sharks and insects etc
Only large dinosaurs were wiped out over a period of some years,
66 milion years ago ... thats far beyond my imagination
here you see the ring....ahum i see a face too
Perhaps it was us who finally finished off the dinosaurs, when I say us I mean our ancient ancestors who were small rodent like burrowing mammals. These ancient mammals would have lived underground eating whatever they could find, roots, dead animals and dinosaur eggs. The dinosaurs may have made an eventual comeback but the mammals ate their eggs preventing this. Even today rats from ships landing on remote islands can wipe out ground roosting birds.
And of course, this would explain the extinction of ammonites, rudists, marine reptiles and many other groups at the same time. 😂
Rats don't eat broiler eggs?
@rgudduu wasn't rats but rats should eat grain and seeds but will eat anything
??? Video too short, insufficient information. :(
10km.
James Cameron made very impressive special effect here
Best thing that ever happened to mankind
Correction For The Narrator:
the land bridge that was constructed by an asteroid, the same with the gulf of Mexico, those asteroids made bigger impacts then the ones where y’all be lookin’ for
So all the dynasous were gathered at one location, and every one of them perished there and then... not even one was outside the perimeters?
Yes
@@joemariejames4757 And you know this how?
Lol, are you for real? What a dumb question!
There was no “end of the perimeter”
The asteroid hit at such monumental velocity that molten fragments and rock, soil, soot, dirt and dust created clouds that circled the earth and blocked out the sun for multiple years. Sure, there may have been an explosion with a finite blast radius, but even the blast radius would have been a thousand miles in diameter. But the lack of sunlight would have led to mass die offs of plants and vegetation, which led to a collapse of the food chain because large herbivores starved, and large carnivores would have died shortly. Nothing larger than the size of a modern-day cat wouod have survived on the surface, and those mammals would have likely scavenged, eaten insects, or eaten even smaller mouse-sized creatures. Underground seeds would hade laid dormant and would have begun growing again once the multi-year winter was over when the dust clouds cleared.
That's not the way it works.
😀😀 Such a nice explonation. 1 question. Why all dinos died? even ander the sea? Earth gravity was changed! Thats's the main reason!!
someone better invent a warp machine
Dinosaur or any hard carnivorus animal gets extinct not because of Asteroid🕸 but because of drought, famine. Hungerkills. Iceage.
Wtf do you think caused all that lol.
Something decided to destroy all dinosaurs so that human can evolve and live. Poor dinos 💔
“kaboom?”
“Yes astroid,”

What killed dinos was selective yet precise extinction plan from a type 1 or 2 civilization. 😎
This is the only way The Netherlands may ever get a mountain.
Anyone Tell me How is size of Istoroid when Its killed the dionsoures
The Gulf of Mexico is the largest crater from the meteor impact.
One night a raptor wishes from the stars I wish I could fly. Then a shooting star falls down from Earth. Shooting stars can grant your wishes its a prehistoric knowledge. Since ancient times.

I Love dinasaur ..even have died inctinxt by meteroits and asteroids ..Negeri Sembilan Malaysia once is a land of dinasaur, crates creature from Canada migrate to Negeri Sembilan west Malaysia
What killed the dinosaurs? The Ice Age!!!

I know what killed the dinosaurs. Taxes.
You’re not sat in it stop chatting you’ll get slapped😂🤣
The creator wasn't happy with the results of the experiment . . . New it could be better
