It's not the weight that costs so much, it's the dimension (size) of the package that seems to run up costs. I played around with one of the online shipping service's calculator, a 2"x2" cube weighing nine-hundred pounds is pretty reasonable..

Shipping plutonium again?

More like neutrons. That's too dense for plutonium.

409kg/125cc = 3.272kg/cc = 3,272,000kg/m^3.

Plutonium is 19,816 kg/m^3.

Neutrons run around 10^18kg/m^3.

Even though a full 125cc of neutrons would weigh around 125,000,000,000,000kg (125x10^12kg), there's no way to get that density without an abundance of neutrons.

Therefore, he's shipping a mix of plutonium and neutrons (BTW, NOT a very good idea), governed by the equations

10^18 * v1 + 1.9x10^4 * v2 = 409kg, and
v1 + v2 = 125x10^-6.

And yes, I'm bored.
