Imagine our 3-dimensional universe is like a vast, infinite ocean, where every event, every moment, every particle, is a drop of water within it. Our perception of time is akin to a current flowing through this ocean, propelling us from one moment to the next, from one drop of water to another. We can only perceive time linearly, moving forward, and the past, once gone, can’t be revisited, while the future remains unknown until it becomes the present.
Now, let’s conceptualize this extra-dimensional space that resides just above our own, where time stands still. This space isn’t just an ocean—it’s an infinitely layered construct, akin to a 4-dimensional block of ice where every event, every moment, every particle exists all at once, eternally frozen in place.
In this dimension, there’s no flowing current. Instead, every moment in the history of our universe, from the Big Bang to the ultimate fate of the cosmos, exists simultaneously. It’s like a cosmic film reel, where each frame of the film is a particular moment in time, and the entire film exists at once.
Within this timeless expanse, you could look at any moment as if you were observing a scene in a diorama. The birth of a star, the extinction of dinosaurs, your own birth, the building of the Pyramids, every mundane and monumental event throughout the entirety of existence is available to observe, with neither decay nor progress, just eternal stillness.
This static temporality could allow for some form of navigation, unlike our linear experience of time. In our 3-dimensional world, we can navigate in any spatial direction: up, down, left, right, forward, backward. But in this extra-dimensional space, “time” could become a navigable dimension as well, allowing an entity in this space to “move” to any point in the history or future of the universe at will, just as we move around in 3-dimensional space.
However, it’s important to note that we don’t currently have any scientific evidence to support the existence of such a dimension. Our understanding of space-time as defined by the theory of relativity does allow for intriguing concepts such as time dilation and the curvature of space-time, but a dimension where time is entirely static is purely in the realm of speculative thought and science fiction.
Remember, our language and our minds are built around a 3-dimensional, linearly temporal world, and it can be incredibly challenging to truly envision realities that operate differently. But these thought experiments can be fun and sometimes even lead to novel scientific hypotheses!
