No, it is not possible to stop the Earth's rotation using nuclear weapons. The Earth's rotation is a fundamental property of our planet and is governed by the laws of physics. The rotational motion of the Earth is caused by the initial angular momentum it acquired during its formation and is maintained by the conservation of angular momentum.
Nuclear weapons, despite their destructive power, cannot alter the Earth's rotation. The energy released by a nuclear explosion is minuscule compared to the vast amount of energy associated with the Earth's rotation. Even the largest nuclear bombs ever detonated have had negligible effects on the Earth's rotation.
The Earth's rotation is an integral part of the planet's dynamics and has significant implications for various natural processes, including day and night cycles, weather patterns, and the behavior of oceans and atmosphere. Any attempts to stop or significantly alter the Earth's rotation would require an unimaginable amount of energy and would have catastrophic consequences far beyond the scope of human technology.
It's important to note that altering the Earth's rotation in such a manner would have severe and irreversible effects on the entire planet and its ecosystems. Therefore, it is neither technically feasible nor advisable to attempt to stop the Earth's rotation using nuclear weapons or any other means.
