Arthur T Knackerbracket has found the following story:
Reproduceability is key to science. A one-time “eureka!” could be the first step in a paradigm shift — or it could be a fluke. It’s the second, third, and hundredth measurements that put theories to the test.
That’s why recent measurements of the universe’s expansion have piqued interest. Even though astronomers have applied multiple methods relying on completely different physics, they’re still getting similar results: Today’s universe appears to be expanding faster than what’s expected based on measurements of the early universe. Can systematic errors explain this discrepancy? Or are new physics required?
Now Wendy Freedman (University of Chicago) and colleagues have posted a new, "middle-of-the-road" measurement on the astronomy preprint arXiv, adding a twist to the ongoing debate. The study will appear in the Astrophysical Journal.

No, it doesn't. The analogy is constrained to the 2D skin of the balloon expanding the distance between the points without the points moving on the skin. Beyond that, the analogy immediately breaks down.
Remember - all analogies are bad analogies. If they accurately described what you were using them to describe, then they wouldn't be analogies.
