At the risk of being the you-must-be-fun-at-parties guy - why would a planet "made of blueberries" be comprised of any air at all to begin with? :) "Releasing the air that had separated each berry from its neighbors" - the question, at least the way it's phrased here, doesn't say anything about any air. Made of blueberries means made of blueberries, period.

> the question, at least the way it's phrased here, doesn't say anything about any air Nor does it mention water, but blueberries contain water. Likewise, the paper finds "the air content of the berries" to be "211 times the mass of Earth’s atmosphere" [1]. [1] https://arxiv.org/pdf/1807.10553.pdf https://arxiv.org/pdf/1807.10553.pdf page 3

  I'm okay with the water that blueberries actually CONTAIN, and the same with any air INSIDE them. I just don't think that "air that had separated each berry from its neighbors" should count.

      Or sonething else, like Methane. If we put vacuum sealed blueberries on the moon, they wouldn’t be separated by air.

      More importantly, that description means Earth's atmosphere is left behind.

      No, it doesnt mean that.

The original question asked about "closely packed, but uncompressed" blueberries. I think it's more reasonable to assume this means berries with a small amount of air between them (the state of blueberries as the writer was probably thinking of them), rather than a void-free blueberry mass, or blueberries with pockets of vacuum between them.
