It’s like, in this universe, we process time linearly. Forward. But outside of our space time, from what would be a 4th dimensional perspective, time wouldn’t exist. And from that vantage, could we attain it? What we’d see is our space time would look flattened like a single sculpture of matter in a super position, every place it ever occupied. Our sentience just cycling through our lives like carts on a track. See, everything outside our dimension that’s eternity… eternity looking down on us. Now to us, it’s a sphere. But to them, it’s a circle.
