How Scientists Identify Apocalyptic Asteroids Heading For Earth | Naked Science | Spark

Earth is at constant risk from asteroids and other space debris. The vast majority of these impacts are minimal and have almost no effect on the planet. However over the course of its life, earth has been hit with asteroids that caused such major damage that it changed the planet for centuries to come. How do we know when the next major impact could be? Is there anything we can do to stop it?

Good thing it’s only a thousand billion tons and not a trillion tons!

[@sexynelson100]

I like the way the camera zooms in on that guy.. 2:50

[@nrom5960]

He must have been on a space ship for that shot

[@brazendesigns]

Makes me dizzy. I think it’s awful.

[@mrrob7531]

Dr. Massimiliano Vasile…that is a straight up rock star name!!

[@johnhopkins6260]

While comparisons with nuclear weapons is impressive, a detail of the type(s) of energy released by penetrating asteroids may be more informative. (i.e. heat, light, mechanical, etc.)

[@psikeyhackr6914]

2008 before the Russian meteor.

[@Johndoe-ob1]

We should use old production t.v

[@AboveDaInfluece]

Well if an asteroids is headed towards us from the direction of the sun , there's not much we can do because it's impossible to see.

[@alexnorman1432]

NASA has a great idea to save the planet earth 🌍🌏

[@alexnorman1432]

For 1000+3 billion years to save the planet 🌏

[@alexnorman1432]

For more space missions.

[@immanuelnambinga5188]

Were the dinosaurs the only living animals,? Or how did the other animals survived?

[@arnoldalar3629]

Just wondering, why most asteroids hit unpopulated places?

[@AlwaysWrenchin]

Coincidence

[@somayyamughal8313]

This is inevitable

[@VS24AT]

@ 33:10 no, send up a probe towards the sun and as the meteor passes the earth, rendezvous with the asteroid then explode a nuke in a position that gets it to fragment the sun

[@SahMai]

Years ago it used to be ONCE UPON A TIME. Now It's according to the SCIENTISTS.

[@classesanytime]

No worries folks!! If humanity stays on this course, it will have destroyed itself long before any astroid will have the honor to do so!! Humanity will be victorious!! Humanity 1 - 0 Astroid

[@bjabbbjabb1286]

Shoemaker- Levi even 1994 was 21 hits

[@marykohler9281]

It's going to happen so quickly in a split second we all won't feel nothing just won't be on thus earth anymore

[@colinrobert-kv2up]

Fine example of how small, starts look ruin is very local, somewhere far away. 1917 air two yrs zone glimpses. John.

Chelebyansk event not mentioned here

[@sexynelson100]

I wonder how much a small asteroid ( meteorite ) would be worth if it crashed in your garden.. ?

[@mrrob7531]

If we hit a solid asteroid with a nuke how would it do more damage? Wouldn’t it break it into so many smaller pieces that would eventually burn up in our atmosphere? I know it wouldn’t magically go away but I would think it would help to some degree.

[@Gregknows-uj8gg]

My thinking exactly. Some of it would be vaporized by the nuke. It might get knocked off a path that would hit the Earth some of the smaller particles would burn up in the atmosphere on entry. The down side is the many impacts get spread out more instead of one big one. Neither is good.

[@kenp2392]

So if I understand what you're saying, we need to flood the atmosphere with radioactive material.

[@jsullivan05]

There are actually great videos on youtube on to why it's a bad idea, basically such a small amount would be vaporized that 99% of the asteroid would still be there, just spread out into a "relatively" dense cloud, that cloud would impact out atmosphere and impart the same amount of energy into it, heating it to thousands of degrees. Also we wouldn't be able to use thermonuclear weapons but conventional uranium/plutonium weapon only as it would technically do more damage (i'm not sure on the reason behind this, I think that was just about using one to knock it off course, but basically if I remember right it's because most of the damage from thermo is from the xray emission heating the earths atmosphere up where as conventional nuclear uses more of a blast wave).

[@user-eh9li5tx7h]

This is a good documentary but, like all docs of this type they quickly become dated. The DART mission changed things quite drastically, for the better.

[@alexnorman1432]

Well not anytime soon.

[@cvayas.]

Does anybody know in what year, this video was originally published?

[@OzFPVflyer]

1913 and reuploaded a thousand times for youtube revenue.

[@NunoPereira.]

2008. Check at 45:23 MMVIII

[@cvayas.]

@@NunoPereira. thanks! I find spark a respetable channel. Though misleading viewers by not being clear on the publishing date, I feel totally clickbaited.

[@johnsmythe7940]

Well if it is coming,why are the world worrying about world war?

[@alexnorman1432]

Today the impact scale is zero 0

[@realchron1]

The meteor that killed the dinosaurs happened to have hit a sulfur deposit which is why we are here now. If it had hit ten km away in any direction the dinosaurs would still be here and we would not.

[@campursarian1977]

Isn't a thousand billion another name for 1 trillion? Why not say one trillion?

[@Gregknows-uj8gg]

Because a thousand billion sounds bigger and is more scaryer then one trillion too some. It also might have something too do with the thinking process of professors and scientists. They obviously think differently then say your average Plumber or tradesman.

[@skessisalive]

They always compare impacts to nuclear weapons or megatons of tnt, but the average person doesn’t know anything about either of those.. There are so many different types of nuclear weapons ranging from small missiles to the largest bombs, the average American thinks a nuke is enough to level the whole country and when they hear numbers like 1200 nuclear weapons in our arsenal they think they can all level a country. It’s a bad analogy and doesn’t really give people a good idea of how powerful impacts are

Fear mongering

[@coffeetalk924]

Facts don't care about your feelings kid

[@TheRoulette77]

i side with moedem , and the kid comment makes you sound like a NY thug or just a jerk@@coffeetalk924

[@coffeetalk924]

​@TheRoulette77 do you have a particular bias against asteroid collision videos, or do you just believe that educational videos regarding any and all natural disasters are somehow nothing more than "fear mongering" agenda based material? (Volcanic eruptions, hurricanes, tsunamis, solar flares, gamma ray bursts, viral outbreaks, etc.) Because frankly, this is the real universe you live in. These things have happened, do happen, and will continue to happen. This is not hyper-exaggerated; irrational "fear mongering". Welcome to reality "kid" 😉

[@coffeetalk924]

​@@TheRoulette77sorry it isn't all candy and fairytales for you

[@moedem]

@@coffeetalk924 their pseudoscience becomes your facts 🤦‍♂️ textbook example of conditioning/grooming

[@TheRoulette77]

"shotgun fires at 600mph asteroid fragments travels 30,000 times faster " come on 18,000,000 million mph this video is full of LIES LIES LIES

[@coffeetalk924]

Actually 160,000 miles per hour. The video made one blunder. Doesn't remotely mean it's full of lies. Can you offer some examples of other inaccuracies?

[@TheRoulette77]

600mph x 30,000 is not 160000 i quoted their words in my comment its 18m . do the math on their volume calculations of size and weights its wildly inaccurate and past the point of exaggerations ..@@coffeetalk924

[@mikekovacich2925]

It could be accurate, if a 150ft asteroid was going 50000km/h it could easily send small particles weighing grams much faster than 50000km/h. You would uses the laws of conservation to find out how fast

[@Gregknows-uj8gg]

You are absolutely correct. A bunch of lies. It is all about money and grants and funding so that the CIA can carry on with it's secret projects too create a one world government. Ha! Ha! Ha! Open the borders! Defund the police. Create more lies!!!
