Age of Universe Nearly Twice As Old As Previously Believed (phys.org) 87

Posted by BeauHD from the would-you-look-at-that dept.
An anonymous reader quotes a report from Phys.Org: Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called "impossible early galaxy problem." "Our newly-devised model stretches the galaxy formation time by a several billion years, making the universe 26.7 billion years old, and not 13.7 as previously estimated," says author Rajendra Gupta, adjunct professor of physics in the Faculty of Science at the University of Ottawa.

For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming from distant galaxies. In 2021, thanks to new techniques and advances in technology, the age of our universe was thus estimated at 13.797 billion years using the Lambda-CDM concordance model. However, many scientists have been puzzled by the existence of stars like the Methuselah that appear to be older than the estimated age of our universe and by the discovery of early galaxies in an advanced state of evolution made possible by the James Webb Space Telescope. These galaxies, existing a mere 300 million years or so after the Big Bang, appear to have a level of maturity and mass typically associated with billions of years of cosmic evolution. Furthermore, they're surprisingly small in size, adding another layer of mystery to the equation.

Zwicky's tired light theory proposes that the redshift of light from distant galaxies is due to the gradual loss of energy by photons over vast cosmic distances. However, it was seen to conflict with observations. Yet Gupta found that "by allowing this theory to coexist with the expanding universe, it becomes possible to reinterpret the redshift as a hybrid phenomenon, rather than purely due to expansion." In addition to Zwicky's tired light theory, Gupta introduces the idea of evolving "coupling constants," as hypothesized by Paul Dirac. Coupling constants are fundamental physical constants that govern the interactions between particles. According to Dirac, these constants might have varied over time. By allowing them to evolve, the timeframe for the formation of early galaxies observed by the Webb telescope at high redshifts can be extended from a few hundred million years to several billion years. This provides a more feasible explanation for the advanced level of development and mass observed in these ancient galaxies. The research has been published in the journal Monthly Notices of the Royal Astronomical Society.

    Let's hypothesize that space and time are emergent properties of more fundamental physics.

    Time being emergent is defendable as for instance light does not experience any passage of time. There is no way to establish that in between two interactions, elementary particles experience any passage of time. All our knowledge of particles is necessarily based on behaviors caused by interactions.

    Space being emergent is also defendable. For instance, an electron is a point particle that does not have any volume. Again there is no way to establish the volume of elementary particles. All our knowledge is based on interactions. There's no way for us to know the properties of particles when they're not interacting with other particles.

    Given the emergent space / time hypothesis, it must follow that the properties of space, time and particles are constant over "time". A deeper physics determines these properties, but we cannot see because our knowledge is restrained by what we measure by interacting.

    • One could however possibly say that the volume of a particle is the universe. The particle field becomes apparent at certain points based on probability and interactions with other fields.

    • "Given the emergent space / time hypothesis, it must follow that the properties of space, time and particles are constant over "time"."

      Yes, I think so. But time isn't constant. The truth is humans have no way of knowing how the Universe formed or how big the universe is or any of that. We can only identify that which we can observe, which we find out every day is only part of the story.

      This is where religion comes in. It's how humans fill (or decide not to fill) the gaps in knowledge, however incorrectl

Granted it's an ad hominem argument but I haven't read this latest paper .. though I do note some straw men in the abstract.

    • Tired light dates back to the 1930s as an alternative explanation for the Hubble red shift, a sort of last gasp of the steady state theory. Then Lemaitre published his solution for GR's field equations which demonstrated an expanding universe, and finally even Einstein conceded the point. The final nail in the coffin for alternative cosmological models came with the discovery of the CMBR in 1964 by Wilson and Penzias, but even by then the number of people who questioned Big Bang cosmology was shrinking.

It was abandoned because it was wrong, and then decades later resuscitated by pseudo-science fraudsters trying t

        • Observational data has disproved Tired Light from the start - even Zwicky admitted this.

          To lose energy, the photons would have to change their momentum - by definition. This would result in the photons no longer travelling straight lines from A to B. The observational result would be that the image of objects would be spread out by an amount dependant on their distance and/or quantity of intervening matter. In other words, distant galaxies would be blurry, and ones near other objects would be even blurrier.
