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.

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.

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.

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.
