Little Red Dots are one of the biggest mysteries from JWST so far. They could be galaxies. They could be supermassive black holes. But they also could be supermassive stars. In fact, this suggestion could help solve another big cosmological mystery about globular clusters. More details on that in this interview.

That was a really informative interview. Thank you Fraser for sharing this with us.
I didn’t even know globular clusters were a mystery. This is one of the best/interesting videos in a while. Really great 😎😎
I just gotta say how way cool this idea is! Even if it proves to not be quite right in the future, especially knowing that the formation of globular clusters is a huge gap in our current knowledge.
The ancient super giant star as an origin for globular clusters seems to imply black holes in said clusters. I don't think these are found.
Excellent interview
A fine interview. The idea that red dots are supermassive stars makes more sense than black holes, it's too easy to reach for the BH explanation for every distant strange object.
Excellent interview, Fraser!
Another fantastic interview. Thank you!!
There was discussion a while back about there not being enough matter in the universe for the standard Big Bang theory to work well, so then there was a lot of focus on possibly having "dark" matter comprise the majority of the matter in the universe. Doesn't this idea of the "deep" field views not having *any* totally dark space if you look hard/long enough provide a *lot* more matter that we had not previously expected?
Solving two mysteries about objects we see in the Universe’s most distant past and other objects in the present with one explanation is such an exciting concept.
That was an excellent interview!
Awesome interview! What a gifted interviewee
