While reading a recent Creation Ministries article Five atheist miracles, I came across this claim:
Here is the first problem: how do you get gases formed in a rapidly expanding primordial universe to coalesce together to form a critical mass so that there is sufficient gravitational attraction to attract more gas to grow a star? Gases don’t tend to come together; they disperse, especially where there is a huge amount of energy (heat). Hey presto! Cosmologists invented ‘dark matter’, which is invisible undetectable ‘stuff’ that just happens to generate a lot of gravitational attraction just where it is needed. More magic!
The author in question seems to be awfully sure of his position. I thought that cosmologist indirectly observed the effects of dark matter and that is why it exists.
Did the hypothesis of dark matter arise to explain how stars formed in the primordial universe?
