I looked up Triangulum on a lark, and learned:
"Unlike the Milky Way and Andromeda galaxies, the Triangulum Galaxy does not appear to have a supermassive black hole at its center. This may be because the mass of a galaxy's central supermassive black hole correlates with the size of the galaxy's central bulge, and unlike the Milky Way and Andromeda, the Triangulum Galaxy is a pure disk galaxy with no bulge."
Triangulum is a spiral galaxy in our local group, perhaps bound to Andromeda or us.

- dylan604 2y agoWhat was the impetus of you looking up Triangulum?
- chasil 2y agoI was curious how much closer it was than the Sombrero (about 10x).
- dylan604 2y agoI thought I missed something in TFA. It's interesting to see how a post can make different readers spin off into various random trains of thought. A fun game would be to make a post like yours and then find the fewest degrees of Kevin Bacon to get back to TFA.
- oidar 2y agoMight it be that in galaxies without a blackhole at the center, civilizations could be much older in that galaxy compared to galaxies like ours?
