Astronomers are concentrating on the mechanics of how matter came together in the early universe as observational tests on the cosmological specifics move forward at a rapid rate. The essential query is: Which came first, galaxies, stars, or black holes?
The early cosmos was composed primarily of dark matter, an unseen, enigmatic kind of substance that predominates and is only known to exist indirectly due to its gravitational pull, and a rather uniform sea of several thousand degree gas.
But the solution to the riddle of the early universe lies in how galaxies, stars, and black holes came into existence.
