We have reached space. Why can't we reach the Earth's core?

Humans will probably not be able to go by themselves to the core. It's extremely hot, and it takes a lot of drilling capacity to get down there. It's approx. 6000 C down there, and it's approx. 6500km below us. It gets tougher and tougher to drill down. read more

It’s approx. 6000 C down there, and it’s approx. 6500km below us. It gets tougher and tougher to drill down. Even if we reach the outer core (the edge of it), the temperature is4000 C and all our metal would melt. We’d have to create machines that withstand such temperatures and pressures. read more

We have a fantastic featured story on the technology employed by Cameron’s submersible, the Deepsea Challenger, to reach such depths. The Mariana Trench is the deepest point in the world’s oceans, though, so humankind won’t be going any deeper any time soon. read more

If the core of the Earth wasn't the way it is, there would be no magnetic field, and we would have all sorts of problems to contend with. None of us will ever set eyes on the core, but it's good to know it's there. read more
