How the universe began has always fascinated both scientific and non-scientific minds. The recent James Webb Telescope observations have led to new debates as well as research which question or challenge the dominant Big Bang Theory. In 2024, a significant study raised doubts about Big Bang Theory and concentrated instead on alternatives like Steady-State Theory.
The Genesis of the Big Bang
This concept suggests that about 13.8 billion years ago, there was an explosion from a singularity or simply primeval atom which was an initial extremely hot dense state. This idea came from George Lemaître, a Belgian astronomer who happened to be a priest, applied Einstein’s equations based on general relativity theory. After this, it split open thereby creating our universe approximately 13.8 billion years ago according to The Big bang theory.
This inflation is more rapid than light can allow. In fractions of seconds in this process, the universe was growing exponentially bigger. As time went by after inflation though particles cooled down formed e.g., protons, neutrons and electrons which combined together to form atoms hence stars were formed along with galaxies among other celestial bodies.
Today however one can still detect Cosmic Microwave Background Radiation otherwise known as CMB representing remnants of the big bang explosion that occurred billions of years ago.

Critiques and Questions
Despite its wide acceptance; The Big Bang Theory has faced various criticisms as well as queries particularly whether it adequately accounts for all observed cosmic phenomena or not. For instance, even if uniformity of CMB or distribution of galaxies are explained by other models or not, there are some reasons why scientists have been searching for alternative explanations to these.
The Steady State Theory
Another perception regarding the origin and evolution of the universe comes from Steady State Theory. According to Fred Hoyle, Hermann Bondi and Thomas Gold, proponents argue that the Universe is eternal and unchanging on a large scale. According to steady-state theory, new matter is continuously created as the universe expands, maintaining a constant average density.
This is contrasted with the Big Bang Model which assumes that everything started with one event and hence the universe’s density has been decreasing over time. Instead of this, Steady State Theory suggests that galaxies are not moving away as a result of initial explosion but due to emergence of new matter between them.
History and Development
Although popular during the mid-20th century, Steady State Theory fell out of favour with growing evidence for Big Bang Theory being one of its main reasons. However, recent observations together with research have forced reconsideration of this model.
In 1918 William MacMillan postulated that the Universe could be in a steady state where matter was constantly being created. James Jeans developed this idea further in 1928 arguing that new matter might be formed at all times. Even Einstein who initially supported The Steady State Model later changed his perspective because his equations indicated an expanding universe.

Observations and Modern Research
In 2024, a bunch of cosmologists and astronomers published fresh research which brought back the Steady State Theory from obscurity. The study of these disparities between the Big Bang Model and continuous creation of matter was presented. It suggested that cosmological principle is not necessarily correct in each case where there is uniformity and isotropy.
This discovery brings up the question as to whether the big bang theory is still valid or not, rather should be replaced with alternative models like steady state theory. This means that science continues to evolve, confirmed theories are tested over time and updated with new information.
Conclusion
Those asking questions and searching about the origin of the universe can obtain more knowledge by reading this article. However, one can get an idea how complicated it is to define how the universe originated. Recent studies have unveiled new knowledge to explore more about this complex secret of nature in more different aspects. The steady-state theory has regained popularity which was ignored for some time. Now the scientists are revisiting the different aspects of the said theory for understanding of the cosmos.
Now we can expect even paradigm shifts in our current knowledge about the universe due to advanced technologies including the James Web Telescope and other observational instruments. Scientific knowledge is continuously changing and updating to answer the questions of people about the origin of universe and the cosmos surrounding our world.
