All holy books proclaim that the end of the world, or the Last Hour, is very near. But how will the end come? Will it be an asteroid hitting the Earth, as the film-makers have portrayed it in their films, bringing the end of our planet? Or will another celestial body knock the Earth out of its orbit? In fact, there is another possibility, which is in line with the signs reported in the holy books. In this book you will read about this possibility with proofs. This book analyses the causes and possible occurrences of the signs reported in the Qur'an and Hadith that will take place before the Last Hour by comparing them with scientific data. The book you are about to read first tries to understand who or what the Gog and Magog mentioned in the holy books might be. What Gog and Magog and the Great Wall of Zulkarnain that prevented them from reaching the earth could be, has been revealed with scientific evidence that is one hundred percent consistent with the verses of the Qur'an and the Hadith. The Holy Qur'an states that when God's promise is fulfilled, Gog and Magog will descend to the earth, fluctuationing inside each other. It also says that they will come from all sides of a convex place. The Qur'an and Hadith give many other clues about them. If you try to understand these clues reported in the Qur'an with scientific data, you can find out what they are. The book also examines the cause of the copper-colored smoke that is predicted to envelop the world before the Last Hour in the Qur'an.It is again being laid out by scientific evidence that the cause of this smoke may be a gamma ray that will hit the earth from space. The book also demonstrates with scientific evidence that the solar system will end in a black hole, consistent with verses and hadiths. This book, written not with rumours but with scientific evidence that matches the verses, claims that the time of the Last Hour may not be far away. In this book you will find the answer not only to how the signs of the Last Hour can be realised, but also why the Last Hour will come. According to scientific predictions, by the early 2100s there will be a significant collapse of ecosystems due to human activities, potentially threatening the continuation of life on Earth. The Holy Qur'an informs us that everything in the universe continues to exist in balance and order. In the Holy Qur'an, the 41st verse of Surah al-Rûm states: "Corruption has arisen on land and sea because of what people have done with their own hands. God makes them taste some of the consequences of their actions, in the hope that they will turn away from the wrong path." The verse says that man will disturb this order created on earth. When this balance and order created by God is disturbed, the time of the Last Hour will have come. The time of the Last Hour will be determined by mankind by what they have done and what they will do.
