The paradox of butter cat is just a hypothesis, but it doesn't exist. You're not the first person to think so. People put forward this idea a long time ago, mainly because this theory ignores the truth that combination causes qualitative change, and it also violates the law of conservation of energy, because if bread and butter fall forever and the cat's feet fall in mid-air, then the combination of cat and butter will never fall. If it keeps spinning, this hypothesis will cause the cat and butter to rotate forever, forming a theoretical "perpetual motion machine". In fact, there is no perpetual motion machine in the universe, because the existing theory proves that all behaviors, changes and actions in the universe must be transferred by energy or mass, so this theory violates the law of conservation of energy and is correct in theory, but it can't be realized. Moreover, the combination of cat and butter is no longer a simple cat or butter, and the rules to be followed are not applicable.
