@cerebro.333: The grandfather paradox is a famous thought experiment about time travel and logical contradictions. The basic idea Imagine you travel back in time and somehow prevent your grandfather from meeting your grandmother (or even kill him) before your parent is born. If your grandfather never has children → your parent is never born If your parent is never born → you are never born If you were never born → you couldn’t have gone back in time to interfere That’s the paradox: 👉 Your actions both must happen and cannot happen at the same time.#Science #facts #time #grandfatherparadox
