  TBF imaginary time is a math trick and not something that actually progresses. It lets us apply results from statistical physics to quantum field theory through a Wick rotation.

  A huge portion of Americans aren’t sure the earth is round and ‘idiocracy’ is fictional.

  I’m okay with the more esoteric things being reserved for those who can comprehend them.

      Fallen into several arguments in Lemmy about exactly that. I have no hard feelings at Mike Judge or even the movie really, but it’s fiction, not a warning from the future. Honestly, people need to stop treating fiction as documentary evidence. At best it’s interesting thought experiments, not something one should base their world view on.

  Oh, you can interpretate anti-matter as either matter that has negative energy and travels forward in time, or matter with positive energy that travels backwards in time, and both interpretation are valid under Dirac’s equation.

  I tried to get multiple physicists to help me mine this imaginary time, but they all said that it was “impossible” and that it’s “not how time works” or something.

  I guess people just really don’t want to jump on this money-making bandwagon.

  I’m still trying to understand perpendicular time

  source

  • GooberEar@lemmy.wtf ⁨5⁩ ⁨weeks⁩ ago

    The easiest way I can explain it is like this: All the sci-fi geeks in the world are familiar with parallel timelines, right? The idea that there’s another RymrgandsDaughter out there living in a world where apes with goatees are the “people” but otherwise pretty much everything else is very similar to how things are for us here and now. But like in perpendicular time, nearly everything is completely different than this current timeline, and yet somehow there’s a point within where I, Gooberear, took the time out of my morning to completely make up this explanation from thin air and which has no basis in actual fact or reality. The end.

    A particle is also a wave, a wave moves back and forth between -X and X passing 0 every time.

    Now, when you measure this particle and it happens to be at zero, sometimes it moves towards X afterwards and sometimes it moves towards -X.

    For the scientists however, all they can measure is that it’s at 0 and half the time it randomly goes one way or the other with 50/50 probability.

    To explain this, scientists imagine the particle has more than 0, but it has a secret momentum hidden into it telling it to deflect positively or negatively.

    Imagine a circle instead of a line. Now instead of crossing zero, you rotate around 0 and hit a Y and -Y axis with X and -X unchanged.

    That y axis that contains the hidden momentum of the particle is called “imaginary” because scientists love loaded terms that are unhelpful to understanding lol.

  • Fluke@lemm.ee ⁨5⁩ ⁨weeks⁩ ago

    Time is as imaginary as up/down, left/right, forward/backward.

    That is to say that the concept and it’s consequences exist no matter what we call it. Time is not a human thing, it’s one of the dimensions of the space in which we exist. Calling it “time” and a “second” being as many vibrations of a caesium as it is, that’s the human bit.

    source

    • KulunkelBoom@lemm.ee ⁨5⁩ ⁨weeks⁩ ago

      Time is a human construct designed for measuring and scheduling and has no meaning whatsoever outside of human endeavor.

      The universe and the infinite space the universe resides in exist at “now” : an important tenet of ‘relativity’. No past. No future. Now. Past, future, time… these are constructs of sentient organisms. The universal “don’t believe everything you think” immediately comes to mind.

      We exist in space. Space is infinite - it has no boundaries or edges, has always existed and will always exist. We also exist in this (“our”) universe - which is infinite, did have a start date, and will come to an end someday. Not soon. Hopefully.

      Space is also infinite “bigger” and “smaller”. But let’s save that for another time.

      (but does cesium REALLY vibrate the same in different parts of space? h’mm?)

  My quick guess would be that this a theory that explain some weird phenomenon we don’t have a good explanation for yet. Like how we observe that stars and galaxies don’t orbit as they should and then say that there is “dark mass” which is responsible.

      Yup. Electrical engineering does something similar. The addition and subtraction of voltages, currents, resistance, capacitance, and inductance in AC circuits is basically unworkable without the shortcut of converting the sinusoidal waves into imaginary phase angles and doing math on them, and then converting them back to sinusoidal waves as necessary.
