Box of Cavendish for Poseidon hunting
The plan is to detect the Russian nuclear torpedo, Poseidon.
This plan is based on the Cavendish experiment.
Plutonium, which would be used in Poseidon, is a massive material.
It takes more than 250 kilograms of plutonium to generate a 500-meter tsunami.
This plutonium also has gravity, and except for friction and air resistance, it attracts surrounding materials with weak force.
If there is plutonium and an aluminum sphere in space, the plutonium would be anchored in the Higgs field and the aluminum sphere would be attracted to it.
aluminum sphere should be attracted to it.
The same situation is created at the bottom of the ocean. There is an enemy submarine E with Poseidon on board, and there is submarine A looking for the enemy submarine.
We prepare a universe inside this submarine A. We have a 1 mm aluminum sphere in a box with a vacuum inside.
The boxes are allowed to free-fall inside the submarine, and the inside of the falling boxes will be weightless relative to the submarine.
Since there is a vacuum inside, there is no air resistance.
In this state, the aluminum sphere is attracted by the total mass of the plutonium in Poseidon and the nuclear fuel in submarine E.
The distance moved by the aluminum sphere is measured in nanometers.
From this measurement, the mass distribution of submarine A and the mass distribution of the seafloor terrain are subtracted by an edge computing device.
Repeatedly drop the box and identify the direction of change from the mean and variance values.
There is a high mass object moving in that direction, possibly submarine E. However, only the horizontal direction is reliable; in the vertical direction, the gravity of the mantle flowing underground is noise.
The distance between the seafloor and the mantle is closer than that of the land.
And the further away from the submarine E is, the smaller the distance the aluminum sphere can move.
Regardless of the feasibility of this plan, we do not know what to do after detecting Poseidon.
The problem is that Putin could remotely detonate the Poseidon and the entire submarine E with a nuclear explosion.
If that happens, he would have no choice but to sink submarine E.
And even if Submarine E launches Poseidon, it would have to sink it in retaliation.
If Submarine E launched Poseidon at its own discretion, Submarine E would be responsible for the enormous environmental destruction.
Submarine A therefore heads for single combat to limit damage to its allies.
The attack will be relentless until the submarine E is reduced to pieces.
But there is no certainty that this is the best course of action, so we will have to rely on military experts.
