In the May 15 <em> Nature,<\/em> he proposes a radical scheme to blast a crack in the Earth&#8217;s  surface and pour in tons of molten iron, along with a grapefruit-sized  communications probe. Gravity would send the iron downward, carrying the  probe with it. Stevenson estimates the wave of liquid iron would  deliver the probe to the Earth&#8217;s core in about a week. To create the  crack, Stevenson needs &#8220;the equivalent of a few megatons of TNT  explosive, an earthquake of magnitude 7 on the Richter scale, or a  nuclear device.&#8221; He also requires at least 110,000 tons of molten iron  &#8212; about an hour&#8217;s worth of the world&#8217;s total iron-foundry production.  Constructing a probe that could withstand the rigors of such a journey  would also be a challenge. Stevenson writes: &#8220;This proposal is modest  compared with the space program, and may seem unrealistic only because  little effort has been devoted to it. The time has come for action.&#8221;  Jules Verne would be proud.<\/span><\/p>\n<h6><em>This news brief appeared in the Random Data column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 5\/27\/2003.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Forget outer space: Let&#8217;s journey to the center of the Earth, where &#8220;fascinating scientific issues are waiting to be investigated,&#8221; says Cal Tech geophysicist David Stevenson.
