[edit] His idea about going down into the Earth

Stevenson's idea includes the use of nuclear weapons to crack the Earth's crust, and then fill the crack with molten iron and a probe in it. The iron, by its sheer density and mass, will reach the earth's core in weeks. Communication with the probe would be achieved with seismic waves.[1][2]
