Now you’re calling me irrelevant.
That, sir, remains to be seen.
The hot-shots at Iowa City are now saying (according to local NPR news) that the damn thing was 30 feet across; which I interpret to mean a sort of spherical hunk of rock or iron some 10 meters in diameter.
Also, fragments of something have been turned in to the U of Wisconsin, Madison.
This is all sort of cool.
