    Imagine never getting to a future where traveling back in time is possible because the consequences of our actions today made it impossible to have a future.

    It’s either A) not bad enough to send anyone back in time to stop it B) so bad no one in the future can stop it

    I want to see a movie where Temporal Agents have to protect Hitler from various time traveling assassins in order to preserve the timeline.

        Yeah basically the only acceptable thing to do was to travel back in time to just after they’ve committed their atrocities and then torture them for their crimes.

        Then basically the doctor points out that this is stupid.

    Either:

    A) It’s not possible and therefore is never invented (most likely based on what we know so far. Traveling forward is easy, just go fast).

    B) There is such severe authority over it that it is never allowed to happen because things would get fucked up.

    C) They do it in a way that no one from the past ever finds out, preventing paradoxes.

      …or they did and we live in the alternate timeline

      …or they could not because humanity would face an extinction event in the future without the current history

      …or they tried, and the Force of Time was such that every attempt fails: agents get heart attacks, weapons misfire, time machines explode

    Underrated time travel novel, ‘The Big Time’ by Fritz Leiber.

    ‘The Law of Conservation of Reality.’ Basically, if you go back into the past and shoot Hitler, he’ll only stay dead for a few hours. When he comes back to life he’ll remember feeling really sick, and a week later won’t even remember that. It takes an army doing millions of changes over thousands of years to make even a slight change to the time line.
