If there's no absolute state of simultaniety then what shall we make of quantum entanglement?
"The Andromeda paradox shows how strange reality actually is.
Two people walking past each other on Earth can disagree about what is happening “right now” in the Andromeda Galaxy, even though they are standing just a few meters apart.
One might say an event there has already happened.
The other says it hasn’t happened yet.
Both are correct.
This comes from Special Relativity, where time isn’t universal. What you consider “now” depends on how you’re moving. Even walking speed slightly shifts your frame of reference, and when that tiny shift is stretched across 2.5 million light-years, it becomes huge.
Important part:
No one can actually see this difference. We still only see Andromeda as it was millions of years ago. This is not about observation, it’s about how reality is structured.
What this really means is simple and unsettling.
There is no single present moment shared across the universe.
“Now” is not universal.
Every observer carries their own version of the present."
