  • This entire “glitch” is posited on the idea that altering your subjective past does not alter your absolute present.

    And you’re right - that’s ridiculous. Why wouldn’t taking away something from the past alter the present? This is called causality and thermodynamics, and it’s one of the reasons physics, as we understand it presently, doesn’t really allow for time travel as it is popularly conceived. It’s not about gold coins, exactly, but the idea that you can’t end up with more energy than you started out with (or the mass equivalent of energy).

    But OP started with the idea that a time machine which break causality and thermodymnamics exists, so I just pointed out how massively broken such a machine would be.


  • Assuming the following conditions:

    • Energy is not conserved - that is, you expend less energy traveling to the past than the net energy value of something you send to or bring from the past.

    • It takes approximately 1 minute for the time machine to recharge and target a new time and location after use.

    • The time machine can transport any object that can be contained in a space, but the space is fairly easy to expand. Think, “setting up a tent”.

    All of this, I should emphasize, horribly breaks physics. But it’s not a stupid question. The answer is, essentially, “the economy, as we know it, collapses.”

    A lot of people are going to point out that you can duplicate energy sources, items, etc… by bringing them from the past. Yes, that’s true. But what people are missing is that this enables exponential growth as well:

    • I buy a gold coin. I put it in a large space.

    • 2 minutes later, I set my time machine to go 1 minute back in time, collect the coin from myself, bring it to the present. Now I have 2 gold coins.

    • 2 minutes later, I do this again - collecting the 2 gold coins and bringing them to the (new) present. Now I have 4 gold coins.

    • An hour later of doing this, I have over 536 million gold coins.

    This works for any reasonably sized object, by the way. A hamburger. A tank of oil. That sweet RTX 5090 for your new gaming rig. A nuclear warhead.

    Society, as we know it, isn’t to survive this. The Earth probably isn’t going to survive this. The universe may very well not, although we’ve already broken so many laws of physics getting to this point that it’s a wash anyway.

    tl;dr - time machines as popular culture imagines them are a cheat code.







  • tl;dr (if I am getting this right):

    • Sometimes moderators don’t get if something is forbidden under the TOS, or believe something should be forbidden but isn’t. Ask an admin if uncertain.

    • Moderators can further restrict content beyond the bare minimum of the TOS. Please don’t complain to the admins if a moderator does this (in good faith, obviously).

    • Conversely, moderators, please read the TOS and don’t tell someone something is forbidden under it if it actually isn’t.

    • Previously, admins told mods to remove content re: Jury nullification when discussing violent crimes.

    • Currently, this has been limited only to discussion of jury nullification of future violent crimes, as it could imply someone should actually perform said violent action because they would be acquitted via jury nullification. As far as I can tell, this is the only actual change of any rule in this post.


    Summary over, personal thoughts follow: That one specific change, I don’t actually have any issue with. Reasonable enough. Obviously the devil is in the details of what is forbidden under “advocating violence”; that is a monstrously complex discussion beyond the scope of this particular announcement. Furthermore, the value of some of the clarifications in this post are dependent on admins actually holding an open dialogue with users, the track record of which is… variable. (I am still waiting on a response from months ago, which I was then told would be available in a few weeks.)

    Additionally, since lemmy.world remains federated with other instances which tolerate unpleasant behavior and I see no indication on this post that this will change, this functionally changes little of users’ ability to access that content and contribute to it anyhow.
