Wow, busy thread. I'll have to catch up with everything later tonight.

After a game clear, and using the Riverperson, it only takes a number of minutes to travel between The Ruins and New Home, as long as you don't stop and talk to everyone on the way. Asriel and Chara could have gone to the Ruins to play (it was Asriel's first home, after all, he's probably nostalgic for it) and returned to the Core Complex to sleep at night.

Chara knew about the Golden Flowers from her village before she fell. She specifically said she wanted to go back to her village and see them again. Her last request might have been a lie, but her knowledge of the flowers was real.

We don't know that all the garbage that fell down the Waterfall came directly from Chara's village. Considering that Alphys was up to date on modern anime, and decrying the fact that Kissie Cutie 2 sucked, I don't think the monster's source of human tech was 300 years behind the rest of the world.
