Sure, and we would probably be able to tell when they were from based on the approaching crafts. It’s going to be amazing to be able to step 50,000 years into the future to see how humanity has turned out. I’d give up anything to have a chance at that.
If you stop to think, a trip to the future is a trip to immortality because you can go to a time where the technology to live forever will be available.
Unfortunately humanity is constantly on the verge of self destruction so I would expect to come back to a radioactive smoldering place with some survivors roaming around still trying to finish one another with sticks and stones.
