and actually reality is much more interesting than a conspiracy theory.

I was thinking the same thing.
It seems the very interesting part of that story got glossed over in that thread -- and that is the fact that the star in question had no elements
heavier than hydrogen and helium.
Stars in our galaxy are multi-generational -- i.e., they are the great great great great grandchildren of very earlier stars that were also devoid of
heavy elements, like that rogue star in that post.
Heavy elements such as carbon and heavy metals such as iron (and heavier) are
only made in stars' supernovae -- and the more generations of
supernovae, the heavier the elements that exist. Each successive generation of star creates heavier elements upon going nova.
For example, our solar system and our sun are rich in heavy elements, meaning that there were probably several generations of stars and supernovae
that occurred over to create the raw materials that made our solar system. The materials that make up our solar system
must have come
from a few generations of supernova.
Carl Sagan said it best when he said
"We are made of star-stuff", which literally means
we humans (our carbon, zinc, the iron in our
blood) were created when a star went supernovae billions of years ago. The iron and other elements that make you were once deep inside a
star.
Almost all of the stars in our galaxy are like ours -- rich in heavy elements. The rogue star ATS member vital overdose mentioned is devoid of these
heavy elements, therefore it probably came from elsewhere -- a galaxy where star formation is not as robust as our own galaxy.
THAT was the most interesting item in that article.
