Deflecting ateroids/comets...

Does anyone have a good website for the advantages and disadvantages of deflecting an asteroid on collision course with the Earth? Thanks.

Try the NASA and JPL websites.

- I'm sure disadvantages couldn't really outweigh the positive...

Lol
I wish such an answer would be sufficient to gain me three marks in a physics exam!

I feel like it's the most important thing at least :3 :lol:
+ We don't all die

- We all survive
- Oh, and if we managed to survive a very large asteroid impact, it may offer valuable resources. Doubtful though.

I concur.

What do you mean by your final point?

Stick Brian Lara up there with a giant cricket bat and project some hologram wickets onto Earth using the ISS.

If we survive a very large asteroid(let's say with a diameter of 10 miles) impact without deflecting it, there's a chance it might offer rare metals. However, apparently most asteroids mostly consist of iron or silicone, which are both common. Even if an asteroid does contain more valuable metals, it's doubtful that they would be worth more than whatever infrastructure the asteroid destroyed during it's collision.

I'm not a physicist though(nor do I study any other sciences atm), so I can't really say much else on the matter xD

Ah yes I see what you mean. Thanks for your contribution.
