The observations made by the James Webb Space Telescope (JWST) have led to a new theory proposed by Rajendra P. Gupta, a physicist at the University of Ottawa, which suggests that the age of the universe is 26.7 billion years, twice the previously estimated age of 13.8 billion years based on the big bang expanding universe concept. The JWST findings indicate that the structure and masses of very early Universe galaxies at high redshifts may be as evolved as the galaxies in existence for billions of years.
These observations are in strong tension with the current standard cosmological model known as the Lambda-CDM model. Gupta’s research introduces hybrid models that include the tired light concept in the expanding universe, with the CCC + TL model being compliant with the JWST observations and stretching the age of the Universe to 26.7 billion years, allowing enough time to form massive galaxies.
Classical Model
The Milky Way is a typical ‘disk’ galaxy, which a shape similar to a pancake or compact disk, rotating about its centre and often containing spiral arms. These galaxies are thought to be the most common in the nearby Universe and might be the types of galaxies where life can develop given the nature of their formation history. https://www.manchester.ac.uk/discover/news/astronomers-find-abundance-of-milky-way-like-galaxies-in-early-universe-rewriting-cosmic-evolution-theories/ |

Black Holes
Scientists theorize that primordial black holes formed in the first second after the birth of the universe. In that moment, pockets of hot material may have been dense enough to form black holes, potentially with masses ranging from 100,000 times less than a paperclip to 100,000 times more than the Sun’s. Then as the universe quickly expanded and cooled, the conditions for forming black holes this way ended. https://universe.nasa.gov/black-holes/types/ |
The JWST’s observations have also led to a rethinking of how galaxies and black holes form, prompting astronomers to consider alternative models to account for the telescope’s surprising discoveries. The telescope’s unprecedented capabilities have provided new insights that are reshaping our understanding of the early universe and the processes that govern the formation of galaxies and black holes. As scientists grapple with these new findings, it is becoming increasingly clear that our understanding of galaxy and black hole formation will likely have to shift to account for the JWST observations.
New Timeline for Galaxies
Recent research and observations have led to a reevaluation of the timeline for the formation of black holes, suggesting that these enigmatic cosmic entities, including massive black holes, could have formed more quickly than previously thought. This has significant implications for the early universe, as the formation of black holes is closely related to the formation of galaxies. Most galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses.
The relationship between black holes and galaxies is a subject of ongoing research, and recent findings have shed light on the co-evolution of black holes and their host galaxies. Astronomers are concluding that monstrous black holes weren’t simply born big but instead grew on a measured diet of gas and stars controlled by their host galaxies in the early formative years of the universe.
These results, gleaned from a NASA Hubble Space Telescope census of more than 30 galaxies, are painting a broad picture of a galaxy’s evolution and its long and intimate relationship with its central giant black hole. Though much more analysis remains, an initial look at Hubble evidence favors the idea that titanic black holes did not precede a galaxy’s birth but instead co-evolved with the galaxy by trapping a surprisingly exact percentage of the mass of the central hub of stars and gas in a galaxy.
The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic nuclei. A tiny fraction of this energy, if harnessed, could power a spaceship. The origin of supermassive black holes remains an open field of research.

erging of Galaxies
The merging of galaxies, particularly in the early universe, played a crucial role in the formation of large galaxies, reshaping our understanding of cosmic evolution. Studies have revealed that large galaxies merged with each other on average once over the past 9 billion years, indicating that galactic mergers have been a common occurrence throughout cosmic history. These mergers have been a driving force behind the formation of massive galaxies, including those resembling our own Milky Way. The James Webb Space Telescope (JWST) has provided unprecedented insights into the early universe, revealing that galaxies like our own Milky Way dominate throughout the cosmos and are surprisingly common. These findings have challenged previous assumptions about the prevalence of “disk” galaxies in the early universe and have highlighted the significant role of galactic mergers in shaping the cosmic landscape The discovery of an abundance of Milky Way-like galaxies in the early universe has flipped the entire narrative of how scientists think about structure formation, indicating that these galaxies formed much earlier than previously anticipated. Astronomers have long suspected that large galaxies, including those hosting massive black holes, formed through the merger of smaller galaxies. The coalescence of galaxies, particularly in the early universe, provided the necessary conditions for the formation of large, complex structures, including the galaxies we observe today. The merging of galaxies has been a fundamental process driving cosmic evolution, shaping the distribution and characteristics of galaxies throughout the universe. The new insights provided by the JWST and other observational efforts have shed light on the prevalence and significance of galactic mergers in the early universe, offering a new perspective on the formation of large galaxies and the evolution of the cosmos.
Concluding Remarks
The recent revelations stemming from the James Webb Space Telescope (JWST) and other astronomical research have reshaped our understanding of cosmic evolution, challenging long-held assumptions about the formation of galaxies and black holes. The prevalence of galactic mergers, particularly in the early universe, has emerged as a key factor in the formation of large galaxies, providing new insights into the co-evolution of galaxies and their central black holes.
These findings have significant implications for our understanding of the early universe and the processes that have shaped the cosmic landscape. As we continue to unravel the mysteries of the cosmos, it is clear that the JWST and other cutting-edge observatories will play a pivotal role in expanding our knowledge of the universe’s early history. The telescope’s unprecedented capabilities have provided detailed views of the early universe, offering a new perspective on the formation of galaxies and the evolution of the cosmos.
The discoveries made possible by the JWST have sparked a reevaluation of our understanding of cosmic evolution, prompting astronomers to consider alternative models to account for the telescope’s surprising observations. In the coming years, as the JWST and other next-generation observatories continue to push the boundaries of our knowledge, we can expect further groundbreaking discoveries that will revolutionize our understanding of the universe’s early history. The era of precision cosmology is upon us, and the insights gained from these observations will undoubtedly shape our cosmic narrative for years to come.
