Well, when she wins, Chara turns the entire timeline into a black void. A state of non-existance.

I think it's safe to say that in this void, everything that isn't Chara herself has been erased.

Mettaton (I got the quote wrong before, thanks for the correction) says Alphys is taking everyone to a place where "you'll never get to them."

This place must not be in the present universe, because in this timeline, Chara just got to everything.

The only way Alphys and her people could be beyond Chara's reach, was if they were in a different reality entirely.

Alternate dimensions have been one of Alphys' primary areas of research for some time. She installs a dimensonal warp box into Frisk's phone in two seconds flat. Imagine what she could do with an entire 2 mintues.

Most of Alphys' technology is derived from Gaster's earlier work, which she's copying or reverse-engineering to figure out how it works.

Alphys has certainly had access to a dimensional portal. Otherwise she couldn't have conducted her research.

We've never seen every part of the Core. It has a system of moveable rooms as a defense mechanism, and also an easy way to hide internal fascilities that Gaster doesn't want the public to see. Anything could be lurking in that building. So just because Frisk didn't actually see this portal during his runs doesn't mean that it doesn't exist.

When Frisk warps back to the beginning after each run, he uses a power greater than his own ability to reload a save, going back far deeper in time. Utilizing this portal might explain this.
