Geography is four-dimensional

Same is true for humans too. About their personality. Constantly changing and you will never meet the same person twice in that sense.

You can't go home again.

I resonate with the first paragraph. Those people raised with beliefs of a time that does not exist anymore happen to be very conservative and refuse to see the change.

“The past is a foreign country; they do things differently there.”

Every geography has a timestamp.

I get the latitude, longitude, and they added time. But what was the fourth dimension? Or third rather, because the post assumption is that time was the fourth added.
