Asteroid into Water: What happens?

Water FX like splish-splash? Or water FX like the discussed change in sea levels, or creating new gulfs on coasts?

Is this splish-splash enough? ;D

Surfs up!

Yay, planetary surfing

So what you're saying is that we'll be able to do this?!

But with giant robots.

Like this?

from a technical stand point i would say it is safe to say the water should lessen the impact damage of the asteroid and the way i see it shouldn't the water fall into the creator after impact depending on its size and speed

It'd be disappointing to me if an asteroid acted like a large nuke. These things are moving at speeds such that a telephone pole sized object would work like a moab, and they are hundreds, even thousands of times bigger (and more massive). If something like in the video scifibookguy posted doesn't happen, it's not even worth the effort to push one of them into the planet.

That's not the original, or complete video, but I have to agree. You are looking at a very VERY large meteor in that video in comparison to the much smaller one covered in the movie Deep Impact.

I don't know how realistic the amount of debris flying into space was, but it's impressive nonetheless. I don't think we'll see a lot of that in PA though, since I bet that'd be a hell of a job to put that kind of aesthetics on impacts.
