Stephen Hawking discussed the potential risks of contacting intelligent alien life. He argued that if advanced aliens visited Earth, the outcome may be similar to what happened when Europeans colonized America, which was disastrous for native populations. Hawking also suggested that advanced alien civilizations may become nomadic, seeking to conquer and colonize any planets they can reach. He warned that in looking at how intelligent life has developed on Earth, we have to consider we may encounter alien intelligence we would not want to meet.
