No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

And you wouldn't have to reverse causality to travel backwards in time. You would just have to travel faster than the speed of light.
If you can travel faster than the speed of light then you can arrive at a destination before you left.
Alternatively, you would need to generate some sort of negative energy and then enter into a wormhole with the negative energy. As you cross the perihelion of the wormhole there is a possibility that rather than being crushed and destroyed and by the unimaginable cosmic forces you are experiencing that the negative energy would cancel it out and you would be able to travel through the wormhole to any point between the moment that you entered it and the moment that it was created.
Both of these statements come with the caveat that these are based on theories and so my ability to explain them is limited not only by my understanding of the theory but also my ability to explain the information that I have, and there is the possibility that even though these are somewhat plausible scenarios once you overcome the massive gap between where we are and where we would have to be to implement them, there is a chance that a new better mathematical theory will replace this information and prove it to be completely and totally false.
Another term for the speed of light is the speed of causality as it is the rate with which causality propagates through the universe.
Traveling faster than the speed of light is, by definition, reversing causality.
I think you're looking at it from the wrong frame of reference.
Technically, time is still moving forward. Time has not moved backwards on a universal scale, you have just traveled in such a way that you arrived at a point in time where your temporal reference frame is different than the rest of the time you are currently occupying.
Your causality has remained uninterrupted by traveling faster than the speed of light.
Traveling faster than the speed of light means that you have exited the universe and re-entered it at a different point.
At the point that your causality reintegrates with the current temporal causality that you find yourself in then a new causality is created.
Once again, this does not alter causality.
You've just put a stitch in time.
I know practically nothing about all the wormhole theories, because I just don't consider them relevant, but from a logical standpoint, the above does not feel correct to me.
The thing is, you would arrive at your destination before the light would arrive there from where you started. So, you could take out your telescope and potentially watch your own launch.
But that doesn't actually put you into the past. It just looks like it when looking into the direction you came from. Light from the other direction will look like you've fast-forwarded through time, because you now get more recent imagery.
I don't have another explanation why someone might think, this might put you into the past...
