Um. I think they're trying to throw a satellite at an asteroid aren't they? And that should work...at least if I know my basic physics, it should. :) David Stone It seemed similar to someone saying, "Would you like to meet my knife collection?" Ryan Johnston on Elaine's sig
A satellite may weight 1-5 tons I guess. A asteriod can be as big as our moon or bigger (Pluto is seen as a kind of asteriod by many scientists). So the mass of most asteroids that could be dangerous for us is so high that it's like throwing stones against mountains.

But what about the huge asteroid that is supposed to collide with Earth in 2019? What are we going to do about that? If we figure out how to divert them now, then we won't have to be nuking them. :~ David Stone It seemed similar to someone saying, "Would you like to meet my knife collection?"

We must always remember that we are an infitismal part of an infinite picture - making the slightest changes could damage the larger system irepairibly. I don't think we should go jumping into everything feet first. Think Godzilla - same thing, just not sci fi. If (and maybe when) something becomes a threat to use then we will be forced to take action to try to prevent it - we are required to through our instinct to survive - but until then is is nothing more than vandalism, which could have a huge unforseen effect.

But if a penny dropped from the Empire State Building can imbed itself in the cement on the sidewalk, then this small object should be able to move an asteroid...right? David Stone It seemed similar to someone saying, "Would you like to meet my knife collection?" Ryan Johnston on Elaine's sig
Surely that prooves nothing more than the structure of cement is flawed.

ESB height: 381 m Penny weight: 1g (?) Energy in penny on top of the ESB: m*g*h = 0,001 kg * 9,81 m / s^2 * 381 m = 3,73761 J Now this is the energy inside the penny to engrave the street. hmmm 4 joule? I think your breakfeast has more power in it :-D. Just kiding!

Right, but it is a mountain that is moving through space along a certain path. If you hit it just right, you can slightly (very very very slightly) change its path. Over the course of time, that small change becomes continuously more significant. Ryan Johnston

But it proves that small objects can impact bigger objects. Besides...millions of people walk that street every day. Thus it would stand to reason that the concrete is strong and well made.

But I don't think energy has anything to do with how a penny imbeds itself in cement. I believe that is an issue of velocity. Which would lead to the penny being imbedded in the cement.

But the Godzilla reference was dealing with chaos theory. You are saying that we could turn a small thing into something huge and menacing. So if we practice on an asteroid, you're saying that we will alter the course of events such that something drastic could happen. Kind of like a butterfly in England causing a Monsoon in Thailand. That's a theory and it's not true all the time. Besides, if we knock the rock a bit, we're just going to send it somewhere far off into space.
