James Webb, discovery of highly evolved galaxies, only 325 million years after Big Bang, have driven one cosmologist, to a new radical theory, the universe is much older than we think , current estimates place the Big Bang 13.8 billion years, ago. University of ottawa adjunct professor, Rajendra gupta has calculated, that it is intact , 26.7 billion years ago, nearly twice as the old model

But experts warn us to be cautious, extraordinary claims required extraordinary evidence, they say, the question arises that how do cosmologists calculate the universe age as 13.8 billion years in the first place, our best estimate are on observation of the, cosmic microwave background radiation (CMB), and measurements of the universe, expansion through Hubble law, says michael Cowely,

Gupta, s new model described in the paper, published in the monthly notices of the Royal astronomical society, takes a completely different approach, gupta also introduced, new physical constants , that change over time, extending the existence of early galaxies, in the universe from the first few hundred million years of the cosmos, to several billion years ago, helping him to conclude, the universe may actually be nearly 28 Bn years old
