Are time travelers invisible to us? in Time Travel General Posted October 20, 2016 at 01:35 PM I second No More Bets comment. When in a Time Travel forum, where there are serious researchers, it is not enough to claim a system of interacting with, or bypassing time without a conceptual framework at the very least. I also find the question “Are Time travelers invisible to us” to be an incomplete question. When would time travelers be visible to us, at what stage of the process in the time travel, and what would they look like to us during the process of time travel might be pertinent here in order to even answer this question. I would also add that Yes, time travel has been achieved.
