Can we ever visit the centre of the Earth????

                            There's a famous book 'Journey to the centre of the Earth' written by French author Jules Verne.The story is about a professor who leads his nephew and a hired guide down a volcano in Iceland to the 'centre of the earth'.They encounter many adventures,including prehistoric animals and natural hazards,eventually coming to the surface again in Southern Italy.

                          Jules Verne's classic makes for exciting reading,but it is pure fiction.The centre of the earth is not a place to visit,unless you like hanging out in a blast furnace.The outer core of the earth,about two thirds of the way to the centre,is molten iron.Deeper yet.at the inner core,the pressure is so great - 3.5 million times surface pressure that iron solidifies even though the temperature is hotter than the surface of the sun.

                               For these very reasons,it can be safely said that it is unlikely that you can visit the centre of the earth anytime in the near future...
