How will the world end? Different religions and their answer

Similar to Hinduism, Buddhism doesn’t focus on an ‘end of the world’, but has the cycle of birth, death, and rebirth of the ‘samsara’. According to Buddhist teachings, all things, including the world itself, are impermanent and will eventually change and decay. But, when the world starts to end the era of its moral decay and enters complete falsehood, and when the knowledge of the 4 noble truths is completely vanished, a future Buddha, Maitreya, will appear on Earth and spread the word of Buddha again, enlightening the world with his knowledge and wisdom.
