The idea that the universe started with nothing but black holes and that they have played a role in creating galaxies is an intriguing concept, but it does not align with our current understanding of the universe's origins and galaxy formation. Let's explore the reasons why.
Big Bang Theory: The prevailing scientific theory for the origin of the universe is the Big Bang Theory. It suggests that the universe began as a singularity, an extremely hot and dense state, and expanded rapidly from that point. The formation of black holes, on the other hand, occurs through the gravitational collapse of massive stars, which is a process that happens within an already existing universe.
Galaxy Formation: Galaxies are complex systems of stars, gas, and dust that have undergone a process of gradual assembly and evolution over billions of years. The current understanding is that galaxies form through the hierarchical growth of smaller structures, such as gas clouds and stellar clusters, under the influence of gravity. These structures come together to form larger structures like galaxies. Black holes, although they play a role in the evolution of galaxies by affecting the surrounding matter, are not considered the primary creators of galaxies.
Black Hole Evolution: Black holes themselves are remnants of massive stars that have undergone gravitational collapse. While black holes can grow by accreting matter from their surroundings, including gas and other stars, they do not possess the necessary mechanisms to create galaxies on their own. Their influence is limited to their immediate vicinity.
In summary, while black holes are fascinating objects with significant gravitational effects on their surroundings, the current understanding of the universe's origin and galaxy formation points to a different scenario. The Big Bang Theory describes the initial state of the universe, and galaxies are thought to form through a process involving the hierarchical growth of smaller structures over vast timescales.
