Okay so spacetime curves and light follows that curve. So how are Globular Clusters “above” our plane? And then is there anything DIRECTLY below the Globular Cluster? How does that work unless it’s 4D but the 4th D is time and time follows “causality?” and doesn’t go up? Help my brain hurts a little
In: Physics
Time is a fabric, a structure that moves, like a clock. From outside we see the entirety of the clock, see it moving and can know where it is, has been and will be. If you lived on the point of one hand it would seem that it always moved forward and you may not be able to see past and future.
To add, a change in time affects the entire structure at once. Looking back to the clock, if I took a marker and drew a smiley at the 6, it would just be there, not in a far away time but instantly. The person living on the moving hand though would not understand this, and see it as something that comes, is and goes away.
