The expanding Universe
This animation, from Hubblecast 79, illustrates a two-dimensional analogy for the expansion of space.
The illustration, akin to using an expanding balloon as an analogy for the expanding Universe, is used in the Hubblecast to highlight when these 2D analogies work, and when they break down.Credit:
