I'm russian. Funny thing about all this is that Chelyabinsk in Russia is stereotypical city of brutalness. We have a lot of jokes like: "Mens in Chelyabinsk never make manicure. Instead they put their nails on a rail and wait for a train". So when meteorite stroke we had a whole new humouros wave with jokes like: "Actually it's a usual thing for Chelyabinsk when giant rock fall off the sky. People didn't think that there is something special about it, so they didn't report."
I read the Wikipedia about the meteor impact and in one of the dashcam videos the residents don't even look at the meteor that just lit up the whole sky, it's hilarious Link to video I was talking about: commons.wikimedia.org/w/index.php?title=File%3AВзрыв_метеорита_над_Челябинском_15_02_2013_avi-iCawTYPtehk.ogv
That was a great day. All my Russian friends were freaking out online saying someone shot a missile at them or something. :D Then when it ends up being a meteoroid, I get to talk about space with them.
Personally, I'd would have been far more at ease if it was a missile. Missiles can be shot down, usually pop-up on RADAR, and unless they're carrying a thermonuclear payload, they can't do too much damage. At most a few buildings would be leveled. But a meteorite can do insane amounts of damage, we have very shoddy ways of predicting them, and have zero defenses against them. It only takes one "big one" to hit us and that's it, game over. Bye bye human race.
Zatknis blat tebya tam nebilo. Voshe kakoy to pridurok, eto on russkim o kosmose raskazzivaet. I was there. The sound wave was so loud my windows cracked. And I forgive you Hank for your pronunciation.
i remember when the meteor fell, it was interesting, one can only wonder why it was never detected by all the tech, it's very dangerous because next time it may not all disintegrate in the sky
We didn't see this one since it was too small for the current asteroid sky surveys to find reliably. The minimum size that they can see varies depending on how brightly colored the objects are but my understanding is that anything under 50 meters in diameter tends to not be seen.
also it is good to note that at that time, we were very focused on Apophis, an asteroid that could potentially be a "death of the dinosaurs" type close to crash on us most of our observations on that period were directed toward the asteroid, to calculate its trajectory, The Chelyabinsk Meteor came from a totally different direction and caught us by surprise
I don't think people realise how small these ones are. Meteor showers are caused by tiny tiny particles, not any bigger than a pea or even a grain of sand. Barringer Crater was made by an object about 50m across, impacting with an estimated 10 megatons. Of course it was bigger in space, so today we would know about it, but it shows how small they can be to cause that much destruction. Plus, the likelyhood of a small meteor like this actually making it intact to the ground are slim, and the chances of hitting anything are slimmer still.
11Sparky111 That is true, but even a small impactor can ruin somebody's day. Tunguska is believed to be in the 60m + range and as far as we can tell, very little reached the ground. The shockwave, however, would have been more than enough to obliterate a major city.
With all this "tech" we have, we can only scan about 1% of the sky at any one time. Even then, we'll only detect the big ones. The small city busters sized ones will easily be missed.
My city is quite close to Chelyabinsk and we saw the meteor fall. There was a flash so bright that many people on the streets were blinded for a while.
I actually have a friend scientist from Novosibirsk. After Chelyabinsk meteorite pieces were recovered, they were transfered to Novosibirsk (because that city has best scientific equipment in the region and, it's closest science city from Chelyabinsk. Meteorite was actually seen from Academic Town in Nsk). So yeah, I know guy, who actually worked with remnants of that explosive rock.
So can you tell me if it had any residual explosive compounds on any of the pieces for it was supposed to have been intercepted by unknown missile which allegedly broke up the meteor up before it hit the ground i would be interested in the truth of these claims
Best thing about this event.... apart from dash cams... Gov: Why wasnt this detected..? Space Agency: We dont have the funding to watch everywhere at once Gov: Take this newly printed money NOW..
Skeletor Jopko you think the movie Armageddon, although Hollywood hyped didn't reflect the caught-off-guard-ness panic that an event like this created? I bet one of the first questions asked by governments to scientists being "are there any more out there heading this way?" And the most likely response being "we have no idea!". I mean its one thing to blow a load of trees down in the wilderness where nobody gives a crap but you capture it on 50 dash cams and you certainly get the attention of the whole world.
i find it FREAKING AWESOME, that things from OUTSIDE EARTH can reach us and we can see them and touch them, jesus christ the universe is SO FREAKING STRANGE
I wonder if they've preserved a chunk of the meteor for a museum or something. After all, you don't get a meteor strike every day. (knocks on wood because 2020)
I believe the reason this meteor get so high profile is because it went straight for a fricking city. It went across some metropolitan area wrecking havoc with its sound blast, and left a crater in the frozen lake that is not too far from that said metropolitan area.
The moon peeking over the North Pole lit up the DEW line across the Canadian Arctic, and a flock of geese over the Atlantic Seaboard has gotten defense systems in a tizzy.... A meteor out of nowhere, with no detected missile launch would have woken the war machine, but it would have settled down in a hurry. Go see "Sum of all Fears," and see just how close we could get with a REAL nuke blast.
Dude, now I remember seing something exactly like that with my dad when I was younger, but it happened in the countryside and we didn't have any cameras. We thought it was an airplane because we were near an airport, but nope, meteor! And even though they scare me quite a bit, meteors are really effing cool and I'm glad I got to witness one.
did you know the NSA can hack into your webcam, if they want?..I don't think dashcams are all that good. At some point they will have wifii and be hack -able
They already hack into your GPS. Those things have a permanent cell phone link. They don't even need an electronic box, they can track you across the entire country, even if you don't ever get spotted by a camera!
Chelyabinsk for Russian meme space is a city-equivalent of Chuck Norris for meme space. So... yeah... It will be a bit hard to fit a Chelyabinsk-sized thank you in a thank-you-space of the universe. Thanks for the episode, Hank)
You've just touched on the main thing that interests me, but then skipped over it almost as if you were told to. How come it wan't detected? Nobody has given me a satisfactory answer yet. They knew didn't they? But they kept it quiet to not cause a panic. I'm convinced.
Picture space. Space is very dark, and infinitely large. Picture a few telescopes and observatories trying to watch over all of that infinite, dark space. Now picture a nineteen meter wide object, AKA the equivalent of a microscopic dot on a microscopic dot on a microscopic dot times a thousand in comparison to the size of space, hurtling at nineteen kilometers per second towards earth and masked by the billions of more interesting pinpoints of light caused by stars. In short, you can hardly ever tell if a meteor is going to strike the Earth, because they're so small and fast and boring and blend in so well with the background.
Cswartz9 Thanks for that, I appreciate all you said, and it does make sense, but I'm still not totally convinced. They didn't have to scan 'all of space' though, surely we have technology that can detect a moving object "close" to Earth? They spotted and announced the presence of 367943 Duende a few days later. This is apparently an 'unrelated' object that is smaller and surprisingly enough isn't going to hit in the foreseeable future. No risk, ok to mention it. I can see it from their point of view; Tell the population a meteorite is gonna hit and you'll probably cause injuries and deaths in the evacuation panic you will inevitably create. Better to not mention it and take your chances? In the case of Chelyabinsk, yes.
BIackMoonCGI Unlike orbital debris you have visually find meteoroids that are heading towards earth. Unless people are looking close enough at a specific area the smaller ones often get missed.
But that theory contradicts the abundantly available information for every meteoroid detected, including the ones with a probability of hitting the Earth. There are several of those wandering around popular media and not one is trying "hide" them to avoid a panic. The other thing is that even if the meteoroid were detected, it's really hard to predict exactly where with strike -indeed, if it will strike at all. Contrary to what you see in the movies, there are lots of factors that affect a meteor's trajectory. Keeping the information secret is not going to avoid a panic any more than giving out the information is going to cause one. Millions of meteors strike the Earth each year and not a single person has been killed by a meteor in recorded history.
Question: In some of the videos that were filmed on the ground right before, during, and right after the shock wave hits, you can here a series of small bangs after the large shock wave. What makes those smaller banging sounds?
The explosion didn't happen all at one; there were several smaller ones as the meteoroid was disintegrating. That was just those smaller ones catching up. It's a bit like with a Space Shuttle reentering and coming back for landing, you will hear a double boom.
Really, I'm actually glad they didn't know about this asteroid beforehand... Could you imagine how much the media would freak out?!? People would freak out about it hitting NYC or London, just madness!
Hank. Can you do am episode on global warming? I don't understand how is it that we are experiencing global warming and getting so much snow and bitter cold up here in NYC. I thought we would be getting warmer winters...not a polar vortex (what is that)
global warming isnt actually making everything warmer, it is just causing the average surface temperature of the earth to increase by a couple degrees. also, it is a natural occurance for the earth to heat up/cool down over millions of years, we're still recovering from the ice age. humans are making it worse, but we're not the source
DJRAMO4LYF How much worse are humans making it though? I have heard some very very varied results and am not entirely sure, so Hank please make include this is the video =D
I've talked to two different Biologists and a Geologist. Each had 30+ years experience. (parents generation were all scientists) We talked for hours but to sum up; "No concrete evidence." scientist speak for 'no evidence', "Don't believe a panel of scientists chosen for their political views meant to give a report to that same body of politicians." and my favorite "The Iceland volcano pumped out more CO2 than humans have since just after the industrial revolution. And we're still here."
Haha, i almost forgot that. I remember browsing TH-cam and all of a sudden it was trending and people were talking about it.. Its almost a year ago man!
Hey could you guys do a video on the effect that repeated meteor impacts have on the mass of a planet on a several billion year timescale? I'm just curious as to whether the accumulated mass is enough to make a noticeable difference.
Well, if you want to get all technical, earth itself is meteor. A large meteor attracted a bunch of other meteors and slowly created a planet. It turned into a sphereoid by its own gravity. So yes, to answer your question, over a several billion year timescale, the mass has changed by approx. 5,972,000,000,000,000,000,000,000 kg, give or take a few 100,000 kg
Amazing! Thanks as always--Do you think you guys could start making sure all of your titles are in the "Title Safe" area of the image? I love watching SciShow on my Plasma, which overscans and so I can't see all the the title animations sometimes. Thanks!
Coolest fact that I thought of: Because it hit the atmosphere with 50x the speed of sound, the banging sound you hear in the videos after the initial shock wave is the meteor burning 50x SLOWED DOWN, and REVERSED as the sound waves from the past reach you!
What ever happened to all the videos that showed a unknown craft moving at incredible speed shoot that thing then zipp away before the meteor explodes. Did you tube remove them? Why?
My suggestion: An episode on pimples! Why some people develop acne, some people just a random pimple, *coughHankcough*, and some people remain clear through out a whole life?
Keith Henriquez Cold and bitter winters in NYC?! Here in Lebanon it feels like early autumn... and we're in the middle of winter I mean come on! I'm not even wearing a sweater!
You mention the age of a meteor... now, I just watched "The Good Stuff" latest episode about time and here's my question: If something hits the earth that has been travelling at a pretty high speed and you then somehow determine its age: What age are you really determining? The one that we could have observed had we been watching or the one that the meteor or whatever we're talking about has lived through?
Can you do a report on the Fukushima situation? If there is any credit to reports of radiation spikes on the west coast, etc. Possibly the cause of that conjoined whale calf that was found of the coast of Mexico? You settling the score would put a good many people at ease. Much thanks.
***** No, it means I did the research, but it wasn't incredibly clear, therefore I decided it might be worth the 20 seconds of my time to simply post a quick question on here to see if anyone knew a more concise definition; which would also allow me to pose them further questions if it was still not clear enough. Don't be such an arrogant asshat.
I may be wrong, but I believe that the reason we would miss a meteoroid on a collision course is just that we never looked at it. There is too much area to cover for us to say we've looked in every direction.
Did you know something HIT AND REDIRECTED THE PATH -there’s a negative video of it which shows something else fly right into it and even seeing small chucks fly off the meteorite.
Not quite. The stars that are out there burning today are still fusing atoms to create new elements. Every time a star goes super nova, it's releasing most of that newly forged star-stuff out into the universe.
Sort of. All of the mass/energy in the universe was created simultaneously by the Big Bang. However, that doesn't mean it was all created in its present form. Stars, planets, asteroids, even the heavier elements weren't directly created by the Big Bang. They have formed from the mass/energy left behind by the Big Bang over the past few billion years.
kiddsock Yes and no... you might be interested in researching hawking radiation. Some particles are created spontaneously and typically annihilated just as spontaneously, but not always. Ergo, newly created matter.
It wasn't detected right away because it was coming from the direction of the sun and the solar wind and all that crap made it impossible for the instruments to pick it up. It was in a blind spot pretty much.
tracking meteors is a huge undertaking but i think its worthwhile...some notice of a large impact would certainly help save lives ...unless its a E.L.E lol
WOW. I was under the impression that the impact area was large, but not the freaking size of the Black Sea, which is what it looks roughly the size of on that picture... Especially seeing Moscow next to it just puts it all into perspective O_O
I live in Washington State, and we just had a meteor burst over us a few hours ago. I was in the path of the sonic boom, which made all my windows shake and set off a symphony of car alarms. . 😂
They're pretty sure it was an Apollo (one of several groups of particularly threatening Earth orbit crossing bodies.) We know of 10k+ Apollo bodies, most bigger than this, and there might be hundreds of k "city killer" size bodies. What's interesting in terms of diverting them, is that the ones most likely to hit us are also the easiest to reach. Some are much more accessible than our Moon or anything else, and most will have far better resources than the Moon. No mine on a planet will ever work resources like a metallic asteroid (some meteorites of which are density 8+, greater than pure Fe) NASA reports that we know of 1400+ NEO bodies easier to get to/from than Mars orbit, some 400+ easier than Lunar orbit.
those scientist tracking all possible threats to earth are great and deserve all the support there is. but in case they find something, there is no solid plan to prevent that we end up like the dinos did.
We didn't see the Chelyabinsk Meteor coming essentially because the sun is bright... Definitely look up the company B612 in all of its Little Prince referencing, space debris dodging, astronaut led awesome.
Was it part of a larger cometary stream and can we have an update upon when the Tunguska/Chelyabinsk's country cousins are next gonna visit Earth's atmosphere ?

Russian dashcams: helping science since 2013
They could almost be considered tools of citicen science.
They actually have good quality too
but mostly Russia dash cams are used to document reckless Kozel road ragers end in traffic accidents ending up in TH-cam videos titled "Only in Russia"
Russian dash cams are ubiquitous because of rampant car insurance fraud. 🙂

But a meteorite can do insane amounts of damage, we have very shoddy ways of predicting them, and have zero defenses against them. It only takes one "big one" to hit us and that's it, game over. Bye bye human race.

Best thing about this event.... apart from dash cams...

It's incredible that space is so large and there's so much distance between all the larger objects but relatively small things still hit other stuff.
Imagine if this had come down in the middle of the Cuban Missile Crisis. We'd all be dead right now. Every last one of us.
Scary thing is, you may be right 😐
Nope wrong
Or never born
there have been a few cases where meteors have triggered early warning systems and near nuclear war.. Good thing humans back then had common sense.
The moon peeking over the North Pole lit up the DEW line across the Canadian Arctic, and a flock of geese over the Atlantic Seaboard has gotten defense systems in a tizzy....

global warming isnt actually making everything warmer, it is just causing the average surface temperature of the earth to increase by a couple degrees. also, it is a natural occurance for the earth to heat up/cool down over millions of years, we're still recovering from the ice age. humans are making it worse, but we're not the source
DJRAMO4LYF
How much worse are humans making it though? I have heard some very very varied results and am not entirely sure, so Hank please make include this is the video =D
it is not called global warming, it is called climate change.
Cold Spell in January, doesn't sound like it should affect the theory of climate change.
I've talked to two different Biologists and a Geologist. Each had 30+ years experience. (parents generation were all scientists) We talked for hours but to sum up; "No concrete evidence." scientist speak for 'no evidence', "Don't believe a panel of scientists chosen for their political views meant to give a report to that same body of politicians." and my favorite "The Iceland volcano pumped out more CO2 than humans have since just after the industrial revolution. And we're still here."
Excellent show.
Haha, i almost forgot that. I remember browsing TH-cam and all of a sudden it was trending and people were talking about it.. Its almost a year ago man!
Hank, you should do a video about why everything cool happens in Russia. Like the dashboard cameras, tanks driving in streets, etc
4.5 billion years old?! That is so awesome!
Hahahaha his pronunciation of "Chebarkul" and then subsequent apology killed me 😂😂😂
Damn, it's been way longer than i thought.
Hey could you guys do a video on the effect that repeated meteor impacts have on the mass of a planet on a several billion year timescale? I'm just curious as to whether the accumulated mass is enough to make a noticeable difference.
+Pauly Mack --Thousands of tons of dust from space fall to Earth every year. Yes, it has made a difference.
It does, it is theorised that most water on earth has came from impact of metor/ites after it's creation.
Well, if you want to get all technical, earth itself is meteor. A large meteor attracted a bunch of other meteors and slowly created a planet. It turned into a sphereoid by its own gravity. So yes, to answer your question, over a several billion year timescale, the mass has changed by approx. 5,972,000,000,000,000,000,000,000 kg, give or take a few 100,000 kg
Great video!
Hank has come so far as a host.
Scishow and MathemaTigris are my favourite channels for learning interesting things!
Amazing! Thanks as always--Do you think you guys could start making sure all of your titles are in the "Title Safe" area of the image? I love watching SciShow on my Plasma, which overscans and so I can't see all the the title animations sometimes. Thanks!
I love how he puts bad things into words. quote "...so we don't get hit in the face with a giant space rock."
They really should have made this video a lot earlier. :/
Hank do a episode on the plausibility of a mass driver, or even a part mass driver/rocket system to reduce the cost of space flight.
Sister in law was living in Chelyabinsk in 2013. Really want to ask her about it when I see her soon.
Coolest fact that I thought of: Because it hit the atmosphere with 50x the speed of sound, the banging sound you hear in the videos after the initial shock wave is the meteor burning 50x SLOWED DOWN, and REVERSED as the sound waves from the past reach you!
You are not getting old at all 🙂
You make potential Extinction Level Events sound so fun.
What ever happened to all the videos that showed a unknown craft moving at incredible speed shoot that thing then zipp away before the meteor explodes. Did you tube remove them? Why?
OMG how am I not subscribed!?!?! I got that fixed real fast!
Do not need to apologize for your Russian, it is not a Russian word, it's a Turkic word and should be pronounced like Cheebarcóól
What you just said about meteors and meteorites, cleared confusion in 5 seconds, that my teachers couldn’t in 3 years.
Looks like that meteor came in
like a wrecking ball.
My suggestion: An episode on pimples! Why some people develop acne, some people just a random pimple, *coughHankcough*, and some people remain clear through out a whole life?
I love how dashcams have made a real scientific contribution
I'm glad it was bigger and heavier than expected. Just means that our atmosphere can handle objects of that size.
Omg Hank you’re so young buddy!!! :)😊
Keith Henriquez Cold and bitter winters in NYC?! Here in Lebanon it feels like early autumn... and we're in the middle of winter I mean come on! I'm not even wearing a sweater!
I think this is the one I saw when I was young
You mention the age of a meteor... now, I just watched "The Good Stuff" latest episode about time and here's my question:
If something hits the earth that has been travelling at a pretty high speed and you then somehow determine its age: What age are you really determining? The one that we could have observed had we been watching or the one that the meteor or whatever we're talking about has lived through?
This channel is great but I really wish he wouldnt do the tobuscus voice. Its not as extreme as Toby but you can definitely here a Tobuscus undertone
Can you do a report on the Fukushima situation? If there is any credit to reports of radiation spikes on the west coast, etc. Possibly the cause of that conjoined whale calf that was found of the coast of Mexico? You settling the score would put a good many people at ease. Much thanks.
Is the main difference between a meteoroid and an asteroid simply the size?
no, an asteriode is a hunk of rock in space, a meteoroid is a hunk of rock entering an atmosphere.
google it instead of asking people on youtube who are watching a video on the same thing you are.. try it.. www.google.com
ZombieNinjaJudo
There is no need to be an ass. I did google it, and was simply asking in order to get a consensus.
*****
No, it means I did the research, but it wasn't incredibly clear, therefore I decided it might be worth the 20 seconds of my time to simply post a quick question on here to see if anyone knew a more concise definition; which would also allow me to pose them further questions if it was still not clear enough. Don't be such an arrogant asshat.
In Soviet Russia, you don't go to moon, moon goes to you.
I may be wrong, but I believe that the reason we would miss a meteoroid on a collision course is just that we never looked at it. There is too much area to cover for us to say we've looked in every direction.
When will we get another evening of awesome??
Did you know something HIT AND REDIRECTED THE PATH
-there’s a negative video of it which shows something else fly right into it and even seeing small chucks fly off the meteorite.
I channel a giant space rock who identified himself as Bob. He says "I'm coming."
...I heard he was just breathing hard.
Thank you for using the metric units!
Am I the only one who would like more of these to come down?? LOL. Minus the injuries, of course.
Isn't everything as old as the universe? LOL
Not quite. The stars that are out there burning today are still fusing atoms to create new elements. Every time a star goes super nova, it's releasing most of that newly forged star-stuff out into the universe.
Sort of. All of the mass/energy in the universe was created simultaneously by the Big Bang.
However, that doesn't mean it was all created in its present form. Stars, planets, asteroids, even the heavier elements weren't directly created by the Big Bang. They have formed from the mass/energy left behind by the Big Bang over the past few billion years.
epicpolyphony But all the material, including the atoms, are that old.
scjones25 not so sure about that Big Bang Theory, Jus as sure as the Pope was about, "Hell/ Adam and Eve"
kiddsock
Yes and no... you might be interested in researching hawking radiation. Some particles are created spontaneously and typically annihilated just as spontaneously, but not always. Ergo, newly created matter.
It wasn't detected right away because it was coming from the direction of the sun and the solar wind and all that crap made it impossible for the instruments to pick it up. It was in a blind spot pretty much.
Keep reminding me about Subbable so I don't forget to subscribe in the future when I have some money to offer
Are there any ideas on where it came from? Oort cloud or asteroid belt between Jupiter and Mars?
tracking meteors is a huge undertaking but i think its worthwhile...some notice of a large impact would certainly help save lives ...unless its a E.L.E lol
Someone has been watching Deep Impact :)
Haha yeah that's where I got it from... Haven't seen the film in years though
What's an ELE ? lol
Daulton Baird extinction level event
I read E.L.E. as as Evil League of Evil. It sort of works.
WOW. I was under the impression that the impact area was large, but not the freaking size of the Black Sea, which is what it looks roughly the size of on that picture... Especially seeing Moscow next to it just puts it all into perspective O_O
I can't believe 4 years have passed.
Space is so cool, man.
*throws a 9001K meteor at you*
It really is. You freeze pretty quickly in it without a suit
I live in Washington State, and we just had a meteor burst over us a few hours ago. I was in the path of the sonic boom, which made all my windows shake and set off a symphony of car alarms. . 😂
They're pretty sure it was an Apollo (one of several groups of particularly threatening Earth orbit crossing bodies.)
We know of 10k+ Apollo bodies, most bigger than this, and there might be hundreds of k "city killer" size bodies.
What's interesting in terms of diverting them, is that the ones most likely to hit us are also the easiest to reach. Some are much more accessible than our Moon or anything else, and most will have far better resources than the Moon.
No mine on a planet will ever work resources like a metallic asteroid (some meteorites of which are density 8+, greater than pure Fe)
NASA reports that we know of 1400+ NEO bodies easier to get to/from than Mars orbit, some 400+ easier than Lunar orbit.
There was a recent one in Minnesota and Wisconsin but since Minnesotans are so nice they don't need dash cameras. :-)
Is 19km/s relatively fast or slow for a meteriod?
Slightly faster than average for an asteroid.
those scientist tracking all possible threats to earth are great and deserve all the support there is. but in case they find something, there is no solid plan to prevent that we end up like the dinos did.
Amazing as always Sci-Show!
Right, I am off to watch a video on Female Bodybuilders which has appeared...
257 views! i finaly made it before the 301
We didn't see the Chelyabinsk Meteor coming essentially because the sun is bright... Definitely look up the company B612 in all of its Little Prince referencing, space debris dodging, astronaut led awesome.
Was it part of a larger cometary stream and can we have an update upon when the Tunguska/Chelyabinsk's country cousins are next gonna visit Earth's atmosphere ?
can you please just make a video about cats? I would actually be so happy.
That's one of the risks for having a huge country! Plenty of space for all kind of objects to fall.
Comet Sighted:-It's an omen-The end is nigh!-The economy, fools!-I wish I lived in more enlightened times...-Sacrifice a human heart to appease the comet!-If only we had comet sense...-Oh Comet, devil's kith and kin...
-1 stability.
Can we please do something about the naming of things?
You know what I find amazing. Never in recorded history has somone died of getting hit directly by a meteor
+Stian Furu Øverbye Earth is around 0.0275% water. Not 60% , I presume that you meant the crust?
+Stian Furu Øverbye Isnt it 71 % or something ?
ammount of earth covered avaliable, ammount of earth people can use(including water[boats]),ammount of land people can exist on,
ammount of land people cant exist on

it's literally just happened to a guy in India
gunmunz im late to the party but have you heard about the dinosaurs?
What minerals and what metals was this made of?
