Astronomers puzzled by little red galaxies that seem impossibly dense

#32Is this what a group of type III civilizations look like on the Kardashev scale? Back when the universe was hot and dense and it was still fun?
occam's razor says probably not

I'm gonna guess that the prominent astronomers at several top-notch universities mentioned have heard of globular clusters, and that the reason it's not mentioned is it's not relevant.
It's unfortunate that during "professional development" we collectively appear to unlearn saying "no". Or, more widely, learn to avoid using simple direct language. It's not limited to scientists :-(
I think it's because the implication of any such question is how/why did they exclude.... It's like when you ask somebody, did you have a nice day? If they respond "yes" or "no", that's breaking the unstated rules of conversation.
And I would add that perceived competence does not preclude elementary solutions or problems. We're all humans, and humans are entirely prone to silliness, regardless of our credentials. NASA lost a near billion dollar Mars orbiter [1] because nobody, of the thousands of highly credentialed people that worked on that project, bothered to ask, 'Did anybody make sure that all components are using the same measurement system (metric vs customary), run a sim, or at least sanity check the data we're getting back?' Because surprisingly, the answer there would have been "no."

#35My personal hope is that they’re white holes that have been heavily red shifted… probably gonna be something way less exciting but none the less interesting.

Oh well.

Well, the universe is very heterogeneous, you see. There's still plenty of hot, dense, and fun to go around, you just have to look in the right places!
“Red galaxies? On a Friday night? They’re so hot and dense and full of obnoxious Level III civilizations, nobody goes there anymore.”

#40Can those be just globular clusters in their 'bright' phase? Globular clusters are not even mentioned in that article, which is weird.

Why? How do the astronomers know that its many stars, how did they rule out its the normal amount but brighter?
