LONDON, England (CNN) -- A group of experts from around the world will Thursday hold a first of its kind conference on global catastrophic risks. Some experts say humans will merge with machines before the end of this century. They will discuss what should be done to prevent these risks from becoming realities that could lead to the end of human life on earth as we know it. Speakers at the four-day event at Oxford University in Britain will talk about topics including nuclear terrorism and what to do if a large asteroid were to be on a collision course with our planet.
