What will happen to our planet in the next 200 years? The most famous scientist since Albert Einstein, Stephen Hawking, who has made profound and inspiring discoveries, predicted an extremely dark and pessimistic future to the Earth and its inhabitants. Here are some of Hawking's most terrifying predictions on how and when our world will meet its demise. Since scientists started toying with genetically engineered viruses to treat human illnesses, they've also discovered other possible uses for them. Nowadays, pharmacists are even combining several deadly viruses into a single shot and doing some weird stuff with DNA mixing. Hawking was a firm believer in extraterrestrial life, and he was convinced that they will eventually invade our planet. And no, unfortunately, they probably won't come in peace. In his final work, A Smooth Exit from Eternal Inflation, completed just two weeks before he died, Hawking predicted that our universe will eventually fade into darkness as all the stars run
