This discovery made me hugely excited: here was silicon-based life living inside the Earth. It would be more biochemically distinct from familiar life than anything we might find on the surface of Mars.
This story reminded me of that dream. We really know very little about what happens in the deepest depths of the Earth. We do know, though, that at the core-mantle boundary we have
- a fluid (liquid iron), that might act as a solvent,
- a solid surface,
- interesting chemistry, and
- a flow of energy.
Maybe those salamanders really are down there, after all.
