For example, there are hints that the galaxies we’re seeing are brighter and more regular than expected given the short amount of time they’d had to grow. Well, perhaps no one was expecting that we’d find a completely new type of star—one mostly made of and powered by dark matter and shining as bright as an entire galaxy. Which, by the way, might help us explain those pesky giant galaxies.

The real Matt O'Dowd would have said "How do you think I survive so long, out here...in Space Time".

Just looked up and read about John Michell. Guy needs more recognition! He predicted black holes in the 18th century and actually conceived of and designed the apparatus for the Cavendish experiment but died before he could carry it out, and then his friend Cavendish finished the work.

Its crazy that John Mitchell had the idea that stars were so big that their gravity wouldn't allow it's light to shine in the 1700s what a under rated astronomer!

I’m practically vibrating with excitement seeing this. Like 20 years ago little 11 year old only recently diagnosed with autism me developed a love for astronomy because my dad had an edition of the Sky at Night magazine that had a piece on theorised dark stars that he let me read and keep. I still have that copy today. My abusive father did only two good things for me while I was still in contact with him - letting me have that copy of that magazine is one of them.
