I mean, there have been 21 confirmed assassination attempts on Hitler and a few more unconfirmed possible attempts. The future did try their best (or just some brave people from the time itself).
Comment on Maybe it was someone from the future.

This was my mostly comical thought. You know how people always say they’d go back and off Hitler? But somehow it never happened so either time travel doesn’t exist, or they just always fail. We’re just getting to see that in real time.
(That said, this fucker definitely changed the future so it’s probably not that.)

Do you realise how many politicians get attacked every day? Do yourself a favour and check it out. It’s a lot, it’s bot not the safest job in the world, many get killed. There had to be an attack by a time traveler at least once

Time travel is possible. Changing the future however, isn’t.
It has to do with wave function collapse. The cat is both alive and dead until its observed, at which point the wave function collapses to reveal which it is.
So let’s say you go back in time and successfully kill Hitler. Well you’re now observing that outcome from a tangent timeline. In our timeline, that wavefront has already collapsed. There’s no takesies backsies. Its immutable.
If you can go back and try again, your just creating new wave front collapses, not changing the ones that already occurred.
Its like re-rolling a dice because you didn’t like the outcome. You can re-roll as much as you want, it doesn’t erase that first roll; its still there, imprinted on the quantum foam of the multi verse.

I’ve always preferred the “creates a new timeline” explanation because it nicely negates the grandfather paradox. And you’re still changing the future, just the future of a different timeline.

Schrödinger was scared of his own results, that’s what his cat is for. Not to show some profound effect about wave function collapse, but to show how the wave function must collapse (despite his calculations showing otherwise) because if the wave function doesn’t collapse, the cat is simultaneously alive and dead, which is preposterous.
However we now know quantum entanglement to be a thing; so, as bizzare as it sounds, the cat is both alive and dead, always. This is strong evidence for a multiverse existence. When you open the box you simply discover which universe you’re in. The number of timelines containing an alive cat diminish over time until eventually dead cat is the only possible outcome.

But what about time crystals ?

My favourite theory of time travel is that in the vast majority of timelines, travelling back in time guarantees that events will unfold as they always will, as given an infinite number of timelines in entropy there will be at least one timeline that forms a loop, and from that point effectively every timeline follows that loop. It may even be a multi-step loop, but it’s still a loop and the time travel causes the events that leads to the time travel.

In my view, it would be naive to assume that killing Hitler before he became Chancellor would guarantee the prevention of the atrocities that followed, and it might even pose the risk of something worse happening. Events don’t occur in a vacuum. It’s similar to how dropping nukes on Hiroshima and Nagasaki were horrific events in themselves, but who’s to say those events aren’t the reason nukes have never been used in warfare since? Preventing those bombings might have saved the people in those cities, but it also might have significantly lowered the bar for using nukes, increasing the chance of a true nuclear holocaust during the Cold War, for example.
So maybe time travel is possible, and someone did try to change history by killing Hitler, but then realized the outcome was even worse. Now, they needed an additional assassin to deal with the first one.

Hiroshima and Nagasaki may have prevented the future that the video game series Fallout predicts.

There’s an interesting theory that Hitler was put in place by time travelers as the last-bad option that wouldn’t destroy the timeline.
Hitler (and Trump) made a number of blundering errors that any idiot should’ve/known better than to make. Had a competent, or even a supervillain-type been in charge, things could’ve turned out even worse than they did. You don’t have to look far- some of these villains attach themselves to those in power. Himmler and Heydrich would’ve been far worse for the world, but were somewhat limited by not being the ones directly in power.
