I wanted to make a hopefully interesting talking topic.
It's about relativity of simultaneity, time as the 4th dimension and such.
Nothing too new, but I'm sure there are many who are not familiar with this, or didn't ponder much over the issue.
What is relative simultaneity:
According to the famous scientist Minkowski's spacetime theory, in special relativity, events that are simultaneous for one observer are not simultaneous for another observer in relative motion. If one observer sets up a line of clocks that are all synchronised so they all read the same time, then another observer who is moving along the line at high speed will see the clocks all reading different times. This was proven by empirical experiments as well.
So, the time being the fourth dimension is an very established and accepted scientific concept.
Now our "positioning" and perspective in this dimension is related to our speed. Here's an excerpt from wikipedia:
"Events A, B, and C occur in different order depending on the motion of the observer. The white line represents a plane of simultaneity being moved from the past to the future."
edit: that v
means velocity and c
means lightspeed, if it wasn't obvious.
So what? So this, for example. Even though we, ourselves have uncertainty about future, and move slowly through the time dimension, a hypothetical ultrafast entity, that resides above this dimension can see past future and now simultaneously, as causes and effects blend into each other.
interesting isn't it?
