Theoretical and Controversial Debates : The Big Bang Theory

The Big Bang theory is the most widely accepted cosmological model that seeks to explain the development of the universe. At the beginning, considerable energies became concentrated at one place thereby producing a reactionary expansion that caused a big explosion now known as the Big Bang. This model explains that matter kept moving away from the center of the explosion and coalescing at different levels to form galaxies.

The Big Bang

To date, celestial bodies are still moving away from each other due to the cosmic forces produced during the big bang. The theory rests upon four fundamental concepts; the hot state of the universe at the beginning, formation and abundance of helium, creation of galaxies and expansion of the universe.Initially, the theory had many skeptics who thought it was far from being infallible.

So much on some scientists who hold on that the Big Bang model is a religious intrusion into the domain of science (Willem, 24). However, overtime scientists were able to make modifications to the tenets that supported the theory in-order to make it consistent with the present state of the universe. The theory of the Big Bang isn’t perfect, and overtime addition and modifications had been made to it in-order to make it more consistent with the universe as it appears to us (John, 5).

The universe is 14 billion years old, over these years of development several cosmological phenomena and forces have shaped the current state of the universe. In-order to predict possible future scenarios of the cosmos it would be pertinent to understand its current and past state. It’s only in its infancy compared to the future. Galaxies are not changing in size or density rather the spacing between galaxies on average is growing (Stephen, 7). We foresee a

future scenario where galaxies would be too far apart to even study or observe them. To mitigate this phenomenon the inter-galactic distances should be monitored to note the drift, angles and distance of separation for purposes of locating galaxies in the future. Another aspect of the universe that is core in discerning its future state is temperature.

During its formation, the universe first experienced very high temperatures that later cooled to form galaxies. A major shift in the scale of the universal temperature is likely to upset the current state of balance and cause and upheaval that would realign the universe structure. The universe was dominated by radiation. The properties of the universe are dependent upon the prevailing temperatures (Abhyankar, 445). The temperatures of the earth crust and other

celestial bodies should be examined periodically to detect irregular patterns in heat fluctuations for purposes of identifying areas of concern.

  1. The expansion may as well face a contraction. What is not clear is whether the galaxies are accelerating from each other or decelerating. If decelerating the gravitational pull may cause them to collapse to one point eventually. Is there a threshold beyond which gravity no longer affects two bodies then this could lead to endless space in as far as we assume space is endless. If however gravity can extend over billions of light years, then the galaxies or whatever will ave remained will eventually collapse into one point, possibly starting it all over again.


      1. Indeed under this assumption, it is expected that with this deceleration the universe will eventually stop expanding and begin a collapsing process which will eventually led to the ‘big crunch’ leading to concentrated energies that may lead to another big bang .and the cycle repeated……see saw kind of….ad infinitum, may be?
