Stephen Hawking, who has made important and inspiring discoveries and is the most famous scientist since Albert Einstein, said that the Earth and its people will have a very dark and sad future.
Here are some of the most scary things Hawking has said about how and when our world will end. Scientists have been experimenting with genetically modified viruses to treat human diseases, but they have also found other ways to use them. Now, pharmacists are even putting together several deadly viruses into one shot and mixing DNA in weird ways.
Hawking was sure that there was life outside of Earth, and he was sure that it would eventually come here. And no, it’s not likely that they’ll come in peace. Hawking’s last book, A Smooth Exit from Eternal Inflation, was finished just two weeks before he died. In it, he said that when all the stars run out of energy, the universe will go dark.
Even though artificial intelligence was a big part of Hawking’s life, he didn’t trust it at all. He once said that it might be “the worst invention in the history of our civilization” because it will probably make humans obsolete. Hawking also said that global warming will change the Earth so that it will be like Venus.
