The universe could well be nearly twice as old as the widely accepted 13.797 billion years. That extraordinary contention in a recent paper by University of Ottawa Professor Rajendra Gupta has the potential to upend much of what one has come to accept about the age of the universe.<br /><br />Prof Gupta’s paper revives a nearly 100-year-old tired light theory and lets it coexist with the expanding universe to arrive at its real age of 26.7 billion years. In a sense, he reinterprets the redshift, or the light stretched by the expanding universe into the red end of the electromagnetic spectrum, as a hybrid phenomenon, rather than purely due to expansion. He spoke to Mayank Chhaya Reports to explain the physics of the age of the universe.
