Hi, I’m really not a physics person, but I’ve heard this and that and was wondering if the following made any sense mathematically.

I’ve seen spacetime and imaginary time depicted as x and y axes forming a cross, but what if spacetime is just an event in imaginary time and imaginary time is just an event in spacetime. To the observer inside spacetime, it’s linear and sequential, whilst imaginary time is nonexistent, and vice versa. Spacetime and imaginary time could both be infinite and nonexistent simultaneously. Therefore; if we place ourselves in ‘observer time’ (looking at the x and y axes from above), there would be nothing but the singularity. This would mean that everything that ever was or ever will be, always is and never wasn’t.

Or to put it another way, could there be no ‘ticking clock’ of time at all? Just a singularity containing a time dimension that has no actual direction, just potential direction for every possible reality. Our Universe could then be both real and illusory simultaneously. To an observer within a given time dimension, said dimension is linear and sequential, but to an observer outside of that time dimension, said dimension is nonexistent.

The reason I ask is, to a non-physics person, who doesn’t really know what is or isn’t possible, such a condition would appear to solve several of the problems that I’ve heard about over the years.

General relativity and quantum field theory could both still be harmonious, and at odds with each other, simultaneously.

Quantum entangled particles, could be both millions of lightyears apart, and still remain together.

The expansion of the Universe, could be speeding up because it’s getting further away from the gravitational influence of the singularity.

Light could have reached us from the far off reaches of the cosmos, because there was never a time when it hadn’t already reached us. It’s just that now that we’re ‘observing’, to us, spacetime is linear and sequential.

Anyway, it's just a thought that came to me, and I thought I'd ask.
