Hi! I’m Michael Keim, the author of the new paper on DF9, the third galaxy missing dark matter. I’m so glad you enjoyed my work! Your video was an excellent review. It was especially satisfying because I myself had originally argued in our 2022 Nature paper that DF9 was part of the trail despite being misidentified in the Sloan Digital Sky Survey as a quasar in the far distant universe (I even had the chance to name it, but replied too late to an email—haha). So discovering that it’s actually the third galaxy without dark matter is the perfect way to wrap up my PhD. Our universe is an incredibly beautiful place. One of the best things about astrophysics is how much there still is to discover.

We have some very dark matters to discuss

Always nice to have a plausible explanation of formation.

👽#1 - "What's that gizmo? 👽#2 - "It's an interstellar flummoxer." 👽#1 - "What does it do?" 👽#2 - "It screws with the instruments, telescopes & probes of primitive planets. Here, I'm pointing mine at earth." 👽#1 - "I didn't see it do anything." 👽#2 - "Well, now they think our entire galaxy, and a few others, have no dark matter. Cool, huh?" 👽#1 - [sigh] "I bet you were the kind of kid who fried ants with a magnifying glass."

alternative theory: galactic housekeeping

0:19 that camera noise looks as bad as my Astro camera. Maybe no galaxies have dark matter

It's kinda of like using panning to separate out the gold from the silt, the heavier stuff gets left behind, while the lighter stuff gets chucked out.

It may be that, besides light, galaxies also emit odors. Combine that with DM apparently being a super smeller...and we now have a full and complete working theory. The only question that remains is why some galaxies are so unhygienic?

The first thing that came to mind when I heard about those galaxies was an ancient “bullet cluster”

It's great that the orbital velocities of those stars can be measured, to check whether they falsify MoND.
