High-temperature and high-pressure experiments involving a diamond anvil and chemicals to simulate the core of the young Earth demonstrate for the first time that hydrogen can bond strongly with iron in extreme conditions. This explains the presence of significant amounts of hydrogen in the Earth s core that arrived as water from bombardments billions of years ago.
Given the extreme depths, temperatures and pressures involved, we are not physically able to probe very far into the earth directly.
