Recent research suggests that the universe might be significantly older than previously thought. Current estimates place the age of the universe at around 13.8 billion years, based on observations of the cosmic microwave background radiation and the expansion rate of the universe. However, a new model proposed by Rajendra Gupta, a physics professor at the University of Ottawa, suggests that the universe could be as old as 26.7 billion years.
Gupta’s model is based on an analysis of “redshifted” galaxies, which are galaxies that are moving away from us at high speeds. As these galaxies move away, their light is stretched to longer wavelengths, which makes them appear redder. By measuring the redshift of galaxies, astronomers can estimate their distance and speed.
Gupta’s analysis suggests that the redshift of galaxies is not constant, but rather changes over time. This means that the universe is expanding at a faster rate than previously thought, which would make it older.
Gupta’s model is still preliminary, and more research is needed to confirm its validity. However, if it is correct, it would have major implications for our understanding of the universe. It would mean that the universe is much larger and more complex than we currently believe. It would also mean that there is more time for life to have evolved elsewhere in the universe.

- New research reveals age of universe estimated to be 26.7 billion years old
The cosmos may be far older than we once believed, according to startling new data from the James Webb Space Telescope (JWST). This revolutionary telescope has upended a cornerstone of modern cosmology, challenging the long-accepted notion that the universe is about 13.8 billion years old
One of the universe’s most confounding mysteries is the discovery of “impossible early galaxies,” a term coined to describe their unexpected formation periods. These galaxies, observed during the universe’s so-called cosmic dawn—roughly 500 to 800 million years after the Big Bang—appear to defy conventional astrophysical models
According to current understanding, such galaxies should not have developed disks and bulges at such an early stage. “It’s akin to seeing a toddler with the wisdom of an octogenarian,” one scientist explains, emphasizing the profound implications of these findings
Yet, there they are: young galaxies appearing as if they’ve undergone vast periods of evolution. Complicating the picture further, some smaller galaxies seem to have greater mass than their larger counterparts, going against conventional wisdom
Recent research, primarily based on observations from the James Webb Space Telescope, suggests the universe could be significantly older than previously believed, with some studies proposing an age closer to 26.7 billion years old, nearly double the previously accepted age of 13.8 billion years; this new theory accounts for the observation of “impossible early galaxies” that appear more developed than expected for their age.
Key points about this new evidence:
- “Tired light” theory:A key component of this new model is the idea of “tired light,” which suggests photons lose energy as they travel vast distances across the universe, potentially making distant objects appear older than they actually are.
- James Webb Space Telescope observations:The JWST has provided crucial data about early galaxies, revealing formations that seem too mature for the current age estimations, prompting scientists to re-evaluate the age of the universe.
- Researcher Rajendra Gupta:A study by physicist Rajendra Gupta from the University of Ottawa is at the forefront of this new age calculation, suggesting the universe could be as old as 26.7 billion years.
