Dark matter, it seems, has been clinging to galaxies for a very long time. Most galaxies that existed 10 billion years ago had about as much dark matter as galaxies do today, contradicting earlier studies that suggested less dark matter lurked around galaxies in the early universe.

The research was recently submitted to the journal Monthly Notices of the Royal Astronomical Society and published Nov. 16 in the preprint journal arXiv. “It wasn’t a complete surprise, but in reality, we didn’t know whether the observational reality would align with expectations from theory.” [The 11 Biggest Unanswered Questions About Dark Matter]
