New research puts age of universe at 26.7 billion years, nearly twice as old as previously believed::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.”

    What about what the CMB tells us? Theory seems to ignore that entirely. I’ll wait for the cosmic neutrino background before I take any of these articles more seriously.

    A sincere thank you for a fascinating, quality post in Technology instead of the usual Threads/Twitter/Reddit posts.

    Before Hubble and also before JWST scientists predicted these telescopes would :
    Hypothesis : show evidence of the beginning of the universe at about 14 billion years.
    Observations again and again nulifies that hypothesis.
    Scientist goes over the top about this in part because they have :

    human needs

    need to publish, need to make a career, need to be recognized as scientists, need to put bread on the table


    And so they come up with this :
    BigBang, acceleration of the expansion : “inflation of the universe”, decceleration : “end of the inflation”, and now a new phase of acceleration !
    Since there is not enough strong non-contradictory evidence to say otherwise, let’s go with Ocam’s razor : whatever more simple theories, even if it hurts scientist’s egos.

    Interesting hypothesis – and totally outside my wheelhouse. I wonder how “tired light” sheds energy without violating the law of conservation of energy. Are they suggesting that our universe is not an isolated and closed system?

      No, nothing like that. Everything is within our universe. He says he has a new way of describing light where it loses energy over time (something weird) and so it explains redshift. His idea says the redshift is wrong and the universe is older. He also says universal constants can change (something never observed before that would fundamentally change physics) and he can explain dark matter.

      So, a lot of over-the-top claims. I’m pretty sure this guy isn’t toppling physics today as the bar is set high for whatever evidence he is sharing.

        Isn’t dark matter just matter we can’t percieve? Rogue asteriods and the like? I admit its been a minute since I studied this stuff, but dark matter isn’t very special.

    It used to be 13.7 billion years± a big margin that got narrowed down to 13.8± a smaller margin. Not seeing that changing unless there’s something seriously wrong with the previous research.

      Narrowing it based on what we can measure doesn’t mean it’s correct.

      The deeper we have stared into the universe the more our base understandings have challenged.

    Are there any constants that we actually know to have varied along the lifetime of the universe?

      I don’t know if this counts as a constant, but I read that time moved something like 5 times slower in the early years of the universe.

        It didn’t as time is relative just like space. There is no absolute standard of time to say “time moves faster”. Faster relative to what?
