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.
