Is “Now”, for me, mathematically the same as “Now” for people on the other side of the world?

I have only a very vague awareness of the idea of relativity but I’m aware that there’s a concept that people in orbit experience less time than those on the planet due to gravity, in some way.

Does this mean that the idea of “now”, as in a moment that is right now, is marginally different for people in other places? Are they experiencing a moment that is in my objective future/past, in a mathematical sense?

Yes, though you will likely never notice the difference.

A scientist took his sons way up on a mountain, and after a weekend proved they had in fact traveled further in time than his wife had, by billionths of a second.

By being so far up, they literally traveled further through space that weekend than she did, and in turn, traveled further in time.
