I admire the candoitness of the proposition but it would take millions to do this. I don't recall how deep the deepest one is, but no one hase ever
drilled,dug or sampled the mantle, everything that anyone's ever been able to drill into has been the crust, no one has ever drilled thru the crust.
Of course, magma flows up to the surface, and sometimes peices of what are thought to be the mantle come out, and there are even entire formations
that are thought o be remnants of mantle/crust systems that are closer to the surface now, but no one's ever actively drilled to it. Thats how thick
the crust is. And whats most bizzare is that its not thick at all. I've heard that, if the planet were reduced to the scale of an apple, then the
crust would be thinner
than the skin.
Im sure funding would come from all areas for this study.
Most drilling done on the planet is for oil and other resources, tho pure research digs do go on. I think
that the deepest borehole
be one thats at least now or until recently was being done for research only (but may've started as an economic bore)
