Seems like cosmologists, astronomers, and physicists might now have enough new food for thought to fill in their boredom with quantum mechanics. Apparently, this result implies new information about dark matter.

No, this is rather a case of the old models probably being the more correct ones: the EDGES result itself was quite unexpected and hard to explain in the existing framework as it was much stronger than expected. Now that EDGES looks to be dead, the old predictions of a weaker effect are validated.

  from the article: “a radio astronomer at McGill University in Montreal who wasn’t involved in either experiment, says that both EDGES and SARAS were extremely thorough in their calibration and analysis procedures, and that it’s too soon to say which result is correct. “The level of disagreement is enough to make people uncomfortable, but I think it’s far from the end of the story,” she said. “From my perspective, it adds to the excitement.” And “Stranger still, the dip was very pronounced, suggesting that hydrogen in the early universe was colder than theoretical models predicted, possibly because of exotic interactions with the dark matter that fills the cosmos. Or perhaps the EDGES dip had a more mundane origin.” The article seems to imply that the EDGES dip may be due to mundane, faulty experiment design, instead. In any case, a little bit of excitement for those scientists.

    Well, while Chiang may not be involved in either EDGES or SARAS, she's not described as having no horse in the race. Rather she's said to be late to arrive with her horse: "[Chiang is] leading another follow-up experiment called PRIZM that will operate on a small island 1,000 kilometers off the southern tip of South Africa".
