I realize there are immense obstacles that stand in our way, as far as engineering and logistics go, but really I’m only talking about sending a probe, or some sort of complex instrument down to the core. Not some sort of fanciful manned mission.
I know there’s heat, pressure, great distance and even the unknown to overcome, but are there any theories built on sound principals that address such a task? And how insurmountable would some of these obstacles be? I can buy that it’s so impractical as to be prohibitive, but it must be possible, at least in theory.
Also, would the opening of an active volcano be a good place for entry? Would this get around having to burrow and drill through miles upon miles of crust?
