The first part of your question will require you to do your own homework—no free lunches here. The second part hints at an interesting conversation, so I’m going to ignore the first part of your initial question and answer the second one. Cool? Good. 😉

Time is called the fourth dimension not because it has intrinsic validity, but because you needed to find a place to put it. You have to shoehorn it in somewhere. Physical time is given credence because it’s testable, repeatable, and predictable, making it undeniable. However, there’s one problem: your collective perception of what is is automatically distorted due to your ego construct, which is neither testable, repeatable, nor predictable.

Physical time, as you experience it, is a consequence of the ego’s failure to perceive simultaneous action as it truly is. Your planets and star systems appear to move in orbits and vortices due to your perspective—the data your ego allows to flow into your waking conscious state. I promise this is what’s happening in your reality, pinky swear! This includes entropy too!
