I was hoping there would be actual simulations of the impact to watch.

And what's the standard deviation?

I was interested in relatively small objects and what they would do to a small area.

Whereas I conjured up an chunk of iron as big as London, and threw it as fast as it would go.

Which reminds me:  Earth Impact Database.

Enjoy.

Some days even my lucky rocketship underpants won't help.


Bring me my Broadsword and a clear understanding.
Get up to the roundhouse on the cliff-top standing.
Take women and children and bed them down.
Bless with a hard heart those that stand with me.
Bless the women and children who firm our hands.
Put our backs to the north wind.
Hold fast by the river.
Sweet memories to drive us on,
for the motherland.

I thought 3rd degree burns at a distance of 10KM from an object that made a 1KM crater pretty sporty.

Somehow, that reminds me of one of R. Lee Ermey's watermelons.

Nice image, but to quell OP's annoyance at us not "playing," I wonder if any projectile would have actually made it through the "target" in the image.  At the velocities involved (35,000 km/sec average, IIRC) tensile strength is such a small, small factor that it essentially does not exist.  Thus, I wonder if the "projectile" would have made it through.

I remember a rather terrible science fiction story about an explorer on Mars who found a bunch of holes through rocks.  Long story short, they were made by a hypervelocity "moon" orbiting at Mars' ground level.  The whole point of the story was to make an awful pun, since the explorer, in thinking up a name for this newly discovered moon, figured that since the other two moons were known as Phobos and Deimos, this one should be named "Bottomos."

I think I quit reading science fiction soon after.

I remember that story.  This appears to be it: The Holes Around Mars.  The google search to get there was distracting.

^ Thanks!  My googlefoodle is sometimes impossible with a 28.8K connection.  (I'm mad at google for screwing up their image searches recently so that it takes a significant part of forever to download results.)

I see what you mean about "distracting."

If you were standing on the opposite side of the planet from the impact, would the s-waves meeting at that point give you a significant jolt?
