Rajendra Gupta from the University of Ottawa published a paper in the Astrophysical Journal based on a modified Lambda CDM + TL model which suggests an age of the universe since the Big Bang of 26.7 Gyr as compared with the consensus view of 13.8 Gyr.

Given that zircon age dates from metamorphosed rocks on this planet, can be reliably dated to ~3.8Gyr the age of the universe of 13.8Gyr always seemed to far too young. Far to young to have accounted for the age of our solar system and the heavy elements within it given their likely origin in pre-cursor supernovae. Far too young given the size of the universe and the current distribution of galaxies, even considering a period of early inflation. Far too young given the recent discovery by the Webb Space Telescope that galaxies as young as 300 Myr after the Big Bang with high red-shift appear to have a structure similar to that of the Milky Way.
