Really? The only time I remember there being multiple worlds were in the special episodes where tomoya had one of the other girls other than nagisa being his girlfriend. If there were other parts that im just not remembering, i'd love to know

Kotomi's parents were researchers who studied another dimension, or something along those lines. Kotomi went on to study the same thing herself in After Story. Also considering the robot and girl in "the world that has ended", which was consistently shown throughout the series, is directly related to the ending. The play that Nagisa wrote is apparently based on that too, both Nagisa and Tomoya were familiar with the story. Then the lights that appear during moments of happiness seem to be connected to the other world if I remember right.
I dunno, seems like it was well established to me.
