How Scientists Identify Apocalyptic Asteroids Heading For Earth | Naked Science | Spark
Рет қаралды 47,804
3 ай бұрынEarth 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?

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.)

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.

@ 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

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 3 ай бұрын
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 3 ай бұрын
So if I understand what you're saying, we need to flood the atmosphere with radioactive material.
@jsullivan05 3 ай бұрын
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).

Isn't a thousand billion another name for 1 trillion? Why not say one trillion?
@Gregknows-uj8gg 3 ай бұрын
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 3 ай бұрын
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

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.

@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" 😉

@mikekovacich2925 3 ай бұрын
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
