      I would say no, for two reasons (Jules Verne may disagree with me…)

      1. The temperature as you move to the earth’s core rises until you get to the core which is calcualted to be around 5300 degrees C (water boils at 100 degrees C), still not hot enough to induce fusion.

      2. The pressure as you move to the core also grows and at the core of a planet hydrogen gas is turned into a metal!

      So, you or your drilling gear would not get very far to be honest.

      hope this helps

      Hi,

      We can’t dig to the centre of the Earth; the farthest anyone’s got so far is just 12km which barely scratches the surface of the Earth’s crust. There are, however, plans to dig further than ever before to try to reach the Moho which is the boundary layer between the outer and inner crust. The Earth’s plates are thinner below the oceans so the International Ocean Discovery programme is trying to dig large holes in the seabed and reach the Moho for the first time (cool article about it here http://www.theprovince.com/technology/Researchers+drill+world+deepest+hole+unearth+mysteries+locked/8863946/story.html)

      So we won’t get to the centre of the Earth but we people are trying to go further than ever before!
