The conversation between human and AI assistant.
Does the fact that nobody has ever visited us from the future mean that time travel is undoubtedly impossible?
That's an interesting perspective. Do you believe that time travel is possible?
As an AI assistant, I don't have personal beliefs, but I can provide some scientific theories on the subject. Some physicists argue that time travel may be allowed by the laws of physics, but it would require technology or resources that are currently beyond our reach. There are also philosophical debates about the very notion of time and whether it can be understood or manipulated by humans.
