Accessing Earth's Core

All of our civilization exists only a thin layer of Earth's surface, and our deepest mines barely scratch our planet. We often talk about finding new mineral resources on other worlds or asteroids in the future, but are we ignore a treasure beneath our feet, and what other technologies and engineering might we utilize in Earth's depths?

@@TheRainHarvester funny thing is: if you just drop a small black hole on earth, nothing much will happen.

The funny thing about this kind of thinking is that you're actually gaining nothing from simply going up, while digging already offered us so many returns. The more we'll dig, the more we'll get. It's definitely harder to do. But we've built our entire civilization out of what little stuff we've dug from the ground and oceans. And by the way, it's downwards that we'll eventually find how to terraform worlds. You gotta get your hands dirty and explore what's inside if you wanna truly understand something. Beside, bacteria already did it without any tech: two thirds of all bacteria live underground, and they weigh, collectively, more than every living things on the surface. Food for thought. Life bunkered itself from the get go. Helps understand how Earth life withstood all that beating.

I always wondered why the interior of the Earth doesn't factor in the Kardadshev scale. We are not a type 0.7 civilization, but more like type 0.00001 civilization.

@movax20h 4 жыл бұрын

That is easy. Total energy flux scales like a radius squared, not qubed. It is proportional to the surfaces not volume.

@N3bu14Gr4y 4 жыл бұрын

This is why the scale should instead be quaturnionic instead of a real number. Have one real number and three imaginary number axes. Your progress in one area might not equal your progress in another, such as space exploration vs. ocean exploration. Under this scale (or vector if you want to split hairs), our Type 3 value would be around one quadrillionth of k thanks to Voyager. I'd rank our total value at around 0.0001i + 0.000000001j + 0.000000000000001k. Remember, we've got to account for the interiors of other planets too, and perhaps even the insides of stars once we've mastered shaping atomic nuclei. As for the real component, that would increase with FTL technology.

If the earth core is the one feeding our magnetosphere, what would happen if we dig enough metals from it? This sound like a good idea that could bring an apocalyptic event. Without a strong enough magnetosphere, we are exposed to deathly space radiations and much more things.

@@jackvernian7779 He simplifies a lot of stuff, but I wouldn't go as far as to say that he ignores physics. He just assumes that humanity as a whole wants something at all costs and goes from there, using every emergent/promissing tech/scientific concept we know to make these beyond-ambitious projects seem possible(graphene for example) in futuristic models. Not saying he's always right, quite the contrary, it's just that he uses something and forgets(or doesn't know) other things that invalidate a concept that he tried to establish, hence the "ignore physics" argument.
