Scientists Have Suggested That The Universe Is Twice As Old As Previously Thought

A new theory calls into question conventional cosmology.
The universe may be nearly twice as old as previously thought: not 13.8 billion, but 26.7 billion years. Furthermore, dark matter and dark energy may not be necessary to explain its structure. Researchers from the University of Ottawa have proposed this alternative cosmological model. New calculations show that it passes one of the most important tests of the Big Bang theory, according to Interesting Engineering (translation by Charter97.org).
The model is called CCC+TL and posits that fundamental physical constants change as cosmic time progresses. The effects that modern science explains by the existence of dark matter and dark energy arise in this theory due to changes in physical parameters.
Researchers Rajendra Gupta and Nikolaos Samaras tested the model based on primordial nucleosynthesis—the process of hydrogen, helium, deuterium, and lithium in the first minutes after the Big Bang.
The predicted abundance of light elements virtually matched the results of the standard cosmological model. “The new model should not contradict the fundamentals of cosmology and astrophysics, and our results stand up to this test,” Gupta stated.
However, scientists are not yet ready to consider this theory proven. Its key assumption—regarding the coordinated change in the rate of the universe’s expansion, nuclear reactions, and neutron decay—requires further physical justification. In addition, the model currently faces discrepancies in calculations of the deuterium content.
New observations, including those of the cosmic microwave background, will be required for a definitive verification.
