Rajendra Gupta Puts Universe at 26.7 Billion Years as JWST Finds Galaxies 280 Million Years After Big Bang

A 2023 peer-reviewed paper by University of Ottawa physicist Rajendra Gupta argues the universe is 26.7 billion years old, nearly double the standard 13.8 billion-year estimate.
Gupta’s case is driven by James Webb Space Telescope findings of massive, bright and oxygen-rich galaxies at extreme redshifts, including MoM-z14 at redshift 14.44—about 280 million years after the Big Bang in standard models.
Those observations deepen the “impossibly early galaxy problem” because heavy elements such as oxygen imply earlier generations of stars had already formed, died and enriched later stars far faster than standard galaxy-formation timelines allow.
Most cosmologists still keep the 13.8 billion-year age and instead argue early galaxy formation was much more efficient; Gupta’s model and similar papers remain minority views despite being published and cited.
JWST is still pushing deeper into the early universe, and continued discoveries of chemically mature galaxies at very high redshift could force either a major rewrite of galaxy-formation theory or a broader challenge to cosmology’s timeline.
If the universe's age is correct, what unknown physics allowed giant galaxies to form so impossibly fast?
Did the universe begin 13 billion years earlier, forcing a complete rewrite of cosmic history?
The "Impossibly Early Galaxy" Problem: How JWST’s Discoveries Challenge the 13.8-Billion-Year Universe and Spark Debate Over a 26.7-Billion-Year Alternative
Overview
The James Webb Space Telescope (JWST) has transformed our understanding of the early universe by discovering remarkably early galaxies, such as JADES-GS-z14-0, that appear both bright and chemically mature. These findings challenge existing cosmological theories, as these galaxies seem far more evolved than models predict for such an early time. Multiple JWST surveys have found that these galaxies show chemical signatures indicating they had been forming stars for at least 100 million years before being observed. This suggests a prolonged period of star formation and the unexpected accumulation of heavy elements, prompting scientists to rethink how galaxies formed in the universe’s infancy.
