Oh these things aren't spherical. They're long and very aerodynamic. Hence, rods, not balls. At the velocities we're talking about, I'm assuming it's going to penetrate very deep indeed. They are bunker busters... they could take out a nuclear bunker... at least so it's theorised. I don't think they'll be finding tungsten a few feet under debris. More like half a mile underneath a crater.



As for the mass of these things, well I've seen various figures, from 2 to 5 tonnes. Obviously I'm not finding any credible sources, it's all the kind of hogwash one associates with conspiracy theories. People jumping to conclusions or quoting "unnamed sources" etc.

I'm thinking that maybe these can go unnoticed from ground level. If they're coated, any light emitted would be very high up and might just look a little strange but otherwise innocent from ground level. But I'm still struggling with the cost of getting them up there. I think for this to happen, we need secret propulsion technology. While I might entertain that idea, it's not something I seriously think is out there.

So I remain very much skeptical of this one.

Not like the oil industry being a bunch of evil bastards. There's no skeptism there!
