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.

That sounds like Geordi’s plan to save the Enterprise.
You’ve got to route it through the deflector dish.
I now want to see a TNG/John Wick crossover.
the baddies killed his Tribble

we need a pause, then have them explain it in an easy metaphor.
And you’re trying to tell me that’s not a magic spell you just said? Pfff
So true king.
Yeah, duh!
Plot twist: all time is imaginary time.
Lunchtime doubly so.
Ever had a pan-galactic gargleblaster?
I read this book when I was an innocent kid and therefore completely missed the genius of
“What’s so bad about being drunk?”
“You ask a glass of water.”(It’s been a long time, might be paraphrasing unintentionally)
Same, though I guess I was old enough to get that because my dad used to be a heavy drinker. I don’t have the book for reference but I think that’s pretty Belgium good.
How could you use such an offensive word in a casual post!
It’s rather like having your head caved in by a lemon wrapped around a gold brick
At least there’s lemon.
But what about second lunch?
Quadruply so, I suppose.
I keep running out of regular time already, now you tell me I need to keep track of perpendicular time?
Yeah but it’s easy, just take the sine of regular time and you’re set.
I thought you had to find the square root of negative time to get it?
Imaginary time are used by a lot of companies in form of your unpaid overtimes
yhea, but then you get paid in imaginary money
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 think you mean charge not energy.
Nope. Anti-matter comes as a negative energy density solution to 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.
Just keeping asking until someone (a go getter) gives you the answer you want.
Come on, this has been a thing for the last 19+12i years
You can have as many dimensions as you want, just keep taking the integral
You can make as many dimensions as you want as long as you clean them up when youre done
You can only build one megastructure at a time
You must construct additional pylons.
I’m still trying to understand perpendicular time
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.
Something something nineteen ninety eight
Damn I wanna meet this ape goatee woman now
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.
Why are they rotating it? I almost understood until you got there
waves are related to circles: if you have a line and anchor it at one end, when you rotate it the other end of the line, it draws a circle, but if the paper you’re drawing it on moves to one side at a constant speed, you’ll get a wave. Alternatively, if you plot where the other end of the line is as time passes (for example, every second or every minute), you’ll get a wave. you can do this in reverse too.
it’s helpful to convert to circles. from a regular wave, at 0 you don’t know if the wave will go up or down without further information. 0 on a circle will correspond to one of two spots, either the very top or the very bottom, and if you know which direction the circle is rotating, you can tell what the related wave will do next.
at least that’s my understanding
If you think about a number line, multiplying 2 by -1 takes you to -2. Multiply it again by -1 and its back at 2.
If you think of the arrow from 0 to 2, all you did was rotate that arrow by 180 degrees to point along the negative axis and back again.
Multiplication by -1 is already a rotation of 180 degrees!
All were doing now is extending that concept to 90 degrees by imagining a second line perpendicular to the original number line.
Two 90 degree rotations need to get to -1 to complete the 180 degree rotation we already expect in normal multiplication.
Giving it the symbol i, this means definitionally i * i = -1. It has to because -1 flips us around the other way on the number line.
That means i is the square root of negative 1.
Any values that use i to store information, even time, could be called “imaginary time”. Really it’s just constantly oscillating between the real and imaginary spaces like a constantly spinning arrow.
Thanks for this! I think it’s the clearest visualization explanation I’ve ever heard for i
The obvious interpretation is that it is 0 real time. Safely ignore, I’d say.
I couldn’t conceive of such a thing!

Regular time is imaginary! That’s what’s differentiate time from space. Well assuming it was Minkowski spacetime they were talking about.
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.
If it makes you feel any better - ALL “time” is imaginary. Time is a human construct that has no meaning outside of human endeavor.
I guess the tauon decays of its own volition then.
I know I do
All particles ‘decay’. Everything particulate decays. what’s your question?
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.
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 finite, 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?)
It vibrates relatively the same, depending on how much of it there is nearby. ;)
Environment.
Shhhhhh if you’re too loud, someone will try to monetize it
you can have imaginary anything. just imagine it! i especially like imaginary unicorns
For clarity, are you imagining imaginary unicorns or just regular non-imaginary unicorns?
it’s actually the square root of a negative unicorn, duh!
