That's one possibility I think is really plausible. Even if our existence isn't ugly, it could be insanely boring to a culture that's scientifically advanced enough to create time travel. They might have developed a way to learn all they need to learn about our time from other methods of inquiry than actually coming back. Plus, because of the Internet, we're documenting our existence in an unprecedented way. There's a reason to go back to see how a long lost civilization like the Aztecs lived because there's less information about their day to day life but modern people even post pictures of their meals online so it may not be necessary.If time travel becomes possible, it's plausible that all of the arts, sciences and cultures of future people are so advanced that it makes ours look infantile in comparison. When I was a little kid, I loved a lot of crappy cartoons that were essentially 30 minute commercials for toys but as an adult, I don't have any interest in them because my tastes of evolved and refined. The difference between a child's taste and an adult's could be a great analogy for how the future might think of our culture. It's really easy for us to think we're incredibly interesting while we're living in the moment but that's hardly an objective account.Here is another possible reason for not having "time tourists" in our time.Because of the development of the technologies and the sciences, the life in the future may have become so much better, that from the future people's perspective, our life as a misery. They may consider our life, as we consider the life in the 1800's when people have been taking feces in holes in the garden or directly on the floor in the palaces, or has had a special spikes on the walls of the palaces, where the people could scratch their heads through the wigs, to comfort their heads from the louses, that they have.Maybe to ask why we don't have tourists from the future is equal to ask why we don't go for a vacation in the local gypsy neighborhood.
They may think of our time as a grouse, dangerous and ugly place.
If you saw Fringe, you could refer to that. A main character had stolen his dead son from an alternate timeline. But the science in Fringe is bullshit after all.I guess. The only thing is now you have to explain how there is now a dead and live version of the child in your timeline. And a missing person in the other timeline. Kidnapping is a crime.
I want the time travel to the past to be true, but is it so? We can't know with certainity until we see a working time travel machine. Can we?Now you are leaving me confused seivtcho, why do you say time travel to the past is impossible? If we do grasp the essence of "time" we go beyond it and we manage to travel to where we want no?
