So, what would a meteorite of the same energy look like?
If that had been a typical meteorite (of density=5 g/cm^3) of the same energy it would be 20x20x20 feet and travelling at 25000 mph.
Your reference to unobtainium, and the ease which which strangelets go through the Earth's iron core:
I guess the real-world analogy is the depleted uranium rounds going through tank armor like butter. Well, the density is an instructive analogy, but the speed isn't.
What I find interesting is the seemingly unending succession of surprises we get from nature.
Agreed. In fact, that's why it IS interesting!
