PostSubject: Asteroids   Tue Oct 06, 2009 2:45 am

there was some discussion about nukes destroying asteroids, this is not plausable, since space has no real particels there is nothing to destry the asteroid after it get'S hit by the nuke, after it get's it gravity will pull the pices together and they will just cous more mayhem, right now as I type there are litterally MILLIONS of asteroids on collision course with the earth, most will burn up but some, evry 4 million years a very big one comes, knocking out life on an entier continent, darkening the skies for hundreds of years.

Antohere thing is actually knowing wethere or not it will hit or not and also seeing it, this is hard, often astrolagist find out weeks after an asteroid just passed us maybe just 200.000km or so, evry week an asteroid passes us large enuf to destroy the world as we know it, nukes will not save us.

Um.... no.

A nearby detonation will knock the object out of it's proposed path. A large enough collision will as well. As for actually breaking it up, ana steroid is, normally, not large enough to have such a strong gravitational pull. Even if it was so large, once the various peices are cast out into space, assuming the detonation large enough, which we don't have anything that powerful yet, they would continue on indefinetely until acted upon by another force. It's not like there will be an invisible point in the center of the rock chunks that will pull them all back.

Which is why we need to keep looking. True, big ones pass us all the time. But we also catch many, many dangerous ones. Apophis is my favourite.

I... what? Space has no real particles? What? What do you think makes up the asteroid itself, dude?

Ha! I can't tell if this is scholarly or just sado-masochistic.

Okay, i know i'm the resident-idiot when it comes to scientific subjects, but i believe matta's talking about the lack of atmosphere in space, which would be necessary to set of the chain reaction that causes the atom bomb to explode? Eh? Maybe?

No. The detonation itself would be sealed within the warhead, and in no way, with a nuke, would requre oxygen like a traditional explosive.All you'd been are the isotopes. Granted there would be no fireball, but there would still be force, and this force, aka shockwave, would work nicely to disrupt the orbit.

the asteroid is on a course around the SUN wich has A FUCKTON( EU approves it's use now) of gravitational power wich is enuf to keep the asteroid in a chain best example is the 1994 impact on Jupiter when a large asteroid broke up before hitting it but it still produces a large enuf explosion to basically annihilate life on earth.

BAsically your argument is that the nuke will knowck it off the proposed path, this may be true for a small asteroid but you still face the possability of raidioactive fragments, hiroshima times 1,000,000

First, yes, it would depens on the sise, as well as, ultimately composition.There are spongy asteroids that wouldn't react at all to a direct hit, and might require several detonations for an orbit alteration. Now, the extreme of said alteration would rely on distance. As for fragments, this would only count for a direct hit. The shockwave's purpose is to PUSH, not destroy. Anything that breaks off would be tiny and easilly burn up. And said fragments could themselves be hit as well. Finally, yes, the sun has gravity, but an object generally the sise of an asteroid, at least of the sise that gets into the inner system, tends to be tinyer. Thank you, Jupiter. And if it was so large, I' rather risk many Hiroshimas raining down than guarenteed breaking up of the Earth's crust.

I think you misunderstand one point when the asteroid is fragmented it is just as bad if not worse the smaller things don't burn up they form a protective chain wich only burns up a littel more.

I am just saying nukes are not an effective way to protect us from asteroids.

Protective chain? What do you mean? If an asteroid is broken up into small chunks they will not be forming a line of death, falling in their battle march. It will be like a abrrage of arrows, a spread. And, um, why would it in anyway prevent them from burning? The atmosphere doesn't have point defence.

And again, any small peices large enough to continue doing damage could be more easilly broken up by even conventional weaponry, thus resulting in a few falling rocks that you might want to stay inside for, and call your car insurance dealership to see if they protect from flaming baseball sised stones. (Note: they usially dont.)
