I put extra effort into editing this one, hopefully it is a bit smoother and easier to watch! Thanks as always for all of your support, interaction and feedback!
So, to add a little bit of additional knowledge, Modern Birds are actually considered full on Dinosaurs, rather than the Direct descendants of Dinosaurs.
That's why modern literature refers to the extinct ones as "Non-Avian Dinosaurs."
5:30 you are incorrect here. There would be no effects except within a couple of miles of the asteroid. It is moving too fast, and the terrain and animals have not had it affect them yet. Not much energy is being given off as it passes, lower level thermal energy. This means that until the collision itself, you would not feel anything.
Yeah, but even if it does produces enough energy to heat up the ground, the asteoid is hypersonic. It hits the earth within seconds, maybe less than a second, so nobody will have enough time to bother about the heat.
The thing about Lava formations known as Deccan traps in India is that they were already forming before the asteroid hit. But the earthquake may have made the situation worse. Now deccan trap region is most fertile place for growing cotton because of black soil.
As the little birb in the bottom right Said, the idea that the Deccan traps started was controversial.
Granted, keep in mind that the video is a year old and we learn new things every day
I know we exist thanks to this, but it makes me extremely sad for them.
It really puts into perspective how powerful nature is.
They got it wrong. Its named the Chixclub Asteroid
isnt it the chixclub impactor? same thing either way
We have named the asteroid now, we know it was definitely asteroid.
Also, it was a sunny day unlike what u said in 5:30 because it was travelling faster than speed of sound. It's not like the movies, it was like a nuke & thus very isntantaneous. Within a second, it went from outerspace to hitting the earth. 100km of distance from karman line of space, to ground covered by a 10+km asteroid.
Wait, we did?
What’s the name?
@@armandoguzmannieves5472 it's called the chixulub impactor
That's a really good point on the traveling faster than the speed of sound, so you're probably right!
Thanks for the name!
@@Mr.Dotson kudos for remembering. I always forget the name & remember it was hard to say & similar to word chihuahua. Google says Chicxulub crater cased by Chicxulub impactor.
And this wasn’t even the WORST mass extinction.
That would be the Permian Extinction
I need to learn more about this one, happen to have a video recommendation on that topic?
There is an even worse extinction event: The great Oxidation event
@@malkariss Here is the link for the great oxidation extinction: ruclips.net/video/H476c8UjLXY/видео.html
@@cafe1925
Wait…?
Do I know about this..?
TELL ME THINGS!
@@armandoguzmannieves5472 Yeah. It's by far the worst extinction event. It's estimated that 99% of species died because of this. It's basically because of oxygen producing bacteria. Early earth lacked oxygen, so the microbes didn't have immunity to Oxygen, so this new by-product produced by this bacteria was toxic to most of the microbes. Not to mention oxygen is very reactive element and it killed most microbes that had delicate chemical metabolism. This event also triggered global cooling, because of oxygen reacting with methane, an abundant gas in early earth, which is a strong green house gas. This cooling in turn, trapped the oxygen producing bacteria under the ice, so they can't do photosynthesis anymore, killing the own producers of oxygen in the process. Yeah, that's the summary. All living beings that are alive today are descendants of those 1% lucky survivors :)
Strange earth time facts:
The pyramids were build in the Stone Age and pre date the extinction of mammoths!
The Egyptians were as ancient to the romans as the romans are to us
Stegosaurus was MORE ancient to tyrannosaurs Rex then tyrannosaurs rex is to us!
Time is insane!
One of the BEST videos on youtube. Gives me goosebumps every time i watch it. Thanks for watching it!
Comparing dinosaurs to humans isn't accurate since they were a bunch of different species, so it's better to compare the time frame they were the dominate animals to the time from which mammals were
05:30 ish We are actually quite confident that a asteroid did hit the earth and was the main event because we found the crater near the Yucatan peninsula in Mexico (Chicxulub crater). The asteroid itself is also called Chxulub.
In reality today we know that the asteroid impact was even more devastating than what we believed. For example, the megatsunami wasn't 1 kilometer but 1,8 kilometer high, and there wasn't one but many of them. Also no, we can't destroy ourselves. Even if we continue with climate change and start a nuclear war, this wouldn't be enough to exterminate us. We just lose a lot of our population, but our species is too adaptable and intelligent to be destroyed so easily and after just few generations it could recover. Even if the old mass extinction repeat themselves, this wouldn't be enough to exterminate humanity. The only thing that can do it now are a supernova, a planetary collision or a black hole, but this events are impossible since we would notice them millions of years in advance
That's a really good point, we are ridiculously adaptive and full of inginuity.
@@malkariss
Nuclear weapons are becoming more powerful.
It will one day bevome powerful enough to kill us all.
Actually one of our main enemies are viruses and plagues (as we could experience in 2020). Our species are basically clones one from another, we have little to no genetic pool (the races and such are just superficial differences that doesn't even reflect on the DNA .. yes, we kill each other over nothing) since modern humans come from a few survivors from the Toba extinction. Meaning that if a really powerful plague comes and we don't have enough resources to combat it, we will probably die. Not to mention that scientists found ancient bacteria from the dinosaur age living in suspension on the Antarctic fields, waiting for the ice to melt and come back to life.
But yeah, it's almost impossible to kill us by brute force, we are basically too many individuals and we reproduce quite fast besides being relatively tall
75% is nothing. The extinction event at the end of the Permian was way worse over 90% of life gone. Was so bad it's called "The Great Dying "
Or the great oxidation event killed 99.9%
You know sedimentary deposits? Those bands of chalk containing fossils that tell us about prehistory?
80s geologists found tons of *iridium* (a metal) in the rock layer separating us from the dinosaurs. Iridium is rare on Earth, but common in asteroids. That’s where the impact theory was born. Didn’t get confirmed til the 90s when they discovered a matching crater in Chicxulub
So that's why we theorized about the meteor prior to discovering the crater?! Thanks, I had no idea.
17:16 that wasnt even the worst one the great dying killed about 85% i think
0:40 hopefully
Uhh yeah I agree, not a good intro, if your in a test then your a testee
When I was editing it together, I just had to keep that in; it was unplanned and cracked me up haha!
5:16 nah we know for sure this happened we just didn’t really give the asteroid itself a name
Chicxulub
@@hareecionelson5875That's the name of the crater, not the asteroids name. The asteroid is most of the times called the "Chixulub impactor" which isn't really its own name.
@@Angel_Sony Chicxulub impactor should be the name of a heavy metal band
Seeds would survive better then adult plants.
Its also theorized that its the reason all birds today have no teeth
Ah, that makes a ton of sense, this would be why we preserve seeds instead of plants in the "Armageddon Seed Vaults"? That's a really cool theory about the birds!
@@malkariss I heard about in in moth like media RUclips channel.
It is named it's called chicxulub
Thank you!
We named the crater.
Xiculcub
Oh wow, I'm not even going to try and pronounce that! :D
Humanity as a hole gould survive in a huge catastrophy but nuclear war would be the most devestating.
The more I think about it, I think you're right. We have proven to be exceptionally resilient and adaptive regardless of what is thrown at us. I feel like we would survive on a species-level, almost anything. I also think we have the potential to survive pretty much anything if we really put our minds to it and get over that dang human greed.
Fortunately for us, if there is an asteroid coming our way, we would know the date it will hit us 200+ years sooner. So although we may still not be able to do anything about it when it arrives, we have plenty of time to mentally prepare ourselves, accepting doom n stuff :D
Very true, with the number of us monitoring the skies, we would certainly know of anything significant well before it got here.
Actually, we've failed to predict a lot of close encounters until they were almost close enough to be steered by the Earth's gravitational field.
