we don't need to blow it up, we just need to crack it like an egg

I think if we apply all our engineering prowess to this we can achieve it

Good news! What has been called the first commercial plant in the United States to use direct air capture just opened, and another plant is operating in Iceland! It can remove the exhaust from about 200 cars. It does this by heating limestone to 1,650 degrees Fahrenheit.

Wouldn't it be easier to figure out how to shove the moon into earth at that point?

how big is a nuke really? The Soviets drilled a pretty deep hole, if we just shoved a train of nukes, just one after another, down that hole until one of em blows up and sets of a chain reaction it'd be kinda like a wedge

The best guesses I could find for the efficiency of synthesizing gasoline from captured CO2 were 12-25%. At the high end of that and the low end of this carbon capture cost (and completely ignoring the cost of CO2->Octane, which is significant), this would be $7.50/gallon of gas. You can safely double that for the CO2->Octane portion, since that process also requires both high temperatures and high pressures.

A type of zooplankton found in marine and fresh water can ingest and break down microplastics, scientists have discovered. But rather than providing a solution to the threat plastics pose to aquatic life, the tiny creatures known as rotifers could be accelerating the risk by splitting the particles into thousands of smaller and potentially more dangerous nanoplastics.

Each rotifer, named from the Latin for “wheel-bearer” owing to the whirling wheel of cilia around their mouths, can create between 348,000 and 366,000 nanoplastics – particles smaller than one micrometre – each day.

The animals are microscopic, ubiquitous and abundant, with up to 23,000 individuals found living in one litre of water, in one location. The researchers, from a team led by the University of Massachusetts Amherst, calculated that in Poyang Lake, the largest lake in China, rotifers were creating 13.3 quadrillion of these plastic particles every day.

Plastic can take up to 500 years to decompose. As it ages, tiny pieces break off. Physical and chemical processes are known to break them down, including when exposed to sunlight or when waves grind bits of plastic against rocks, beaches or other obstacles floating in the ocean.

The scientists sought to examine what role aquatic life might play in microplastic creation, especially after the discovery in 2018 that Antarctic krill are able to break down polyethylene balls into fragments of less than one micrometre. Baoshan Xing, a professor of environmental and soil chemistry at the University of Massachusetts Amherst’s Stockbridge School of Agriculture, said they decided to look at rotifers because they had specialised chewing apparatus similar to krill. They wanted to test the hypothesis that rotifers, of which there are 2,000 species worldwide, could also break down plastic.

“Whereas Antarctic krill live in a place that is essentially unpopulated, we chose rotifers in part because they occur throughout the world’s temperate and tropical zones, where people live,” said Xing, the paper’s senior author.

The animals mistake microplastics – fragments of less than 5mm in diameter – for algae, he said.

After exposing marine and freshwater species of rotifers to a variety of different plastics of different sizes, they found all could ingest microplastics of up to 10 micrometres (0.01mm), break them down and then excrete thousands of nanoplastics back into the environment. Polyethylene microplastics from food containers as well as nanoplastics were detected in the rotifers’ bodies.

Xing said their work was “just the first step”. “We need the scientific community to determine how harmful these nanoplastics are,” he said. “We need to look at other organisms on land and in water for biological fragmentation of microplastics and collaborate with toxicologists and public health researchers to determine what this plague of nanoplastics is doing to us.”

Studies have shown that nanoplastics are probably more dangerous for living organisms than microplastics because they are more abundant and reactive.

If rotifers can produce 13.3 quadrillion nanoparticles a day in Poyang Lake, then the amount created worldwide is immeasurably greater. Each microplastic could theoretically be broken down into 1,000,000,000,000,000 nanoplastic particles, which are then more easily spread.

Microplastics have contaminated every corner of the planet, from the top of Mount Everest to the depths of the Mariana Trench, and research has shown they are in many humans’ blood and heart tissue and the placentas of unborn babies. They cause harm in human cells in the laboratory at levels known to be eaten by people via food.

Jian Zhao, a professor of environmental science and engineering at the Ocean University of China and the paper’s lead author, said nanoplastics were not only potentially toxic to various organisms but served as carriers for other contaminants. The release of chemical additives in the plastic could be enhanced during and after fragmentation, he added.

putting aside the non-feasibility of nuclear chain reactions, earth's core is already pretty volatile and well-contained, I don't think nuking the center of the earth is gonna do much. blowing the earth up from the inside seems like a non-starter to me. we need a real planet-cracking system that will lever it open most of the way along the equator, from crust to mantle at minimum. I think if we devote our global society to this we can devise a solution to ensure nobody gets to come after us

Do we have enough nukes to overcome gravity and send chunks of earth careening into space in all directions though? I'm thinking at most we would be able to make some big dents in the surface and irradiate the planet for a long time but I don't we could actually obliterate it to the point it's no longer a planet orbiting the sun.

In other words things will be fine (for the planet, not us)
