Does the fact that nobody has ever visited us from the future mean that time travel is undoubtedly impossible?
I was wondering if you could clarify something for me. Does the fact that nobody has ever visited us from the future mean that time travel is undoubtedly impossible?
The absence of evidence does not necessarily prove the absence of time travel. Some people speculate that time travelers may be following a "non-interference" policy, where they observe but never interfere with historical events. Others believe that time travel may be so difficult or dangerous that it's practically impossible to achieve.
