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.”
You must log in or register to comment.
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
No, not really, because the age of that star is compatible with the age of the universe within the error bars.
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.
Galaxy formation is still an active area of research und different models predict different evolutionary rates
Instead, he proposes a constant that accounts for the evolution of the coupling constants.
That’s exactly what Brans-Dicke theory is trying to do, and other modified theories of gravitation as well. Yet they can’t explain stuff so well as Lambda CDM can.
Overall, tired light pretty much doesn’t work well explaining the perfect black body behavior of the cosmic microwave background or surface brightnesses of galaxies.
Yeah, I’m not convinced, either. It seems like every couple of years, someone puts out an announcement that Lambda CDM is dead, other scientists take a look, and a much quieter announcement correcting their work gets put out.
Yes, this is a bit frustrating. Part of the scientific method is to propose new hypothesis, and that’s what the original author did, so no issue with that. But then there is a chain of increasingly pop-sci media that hype some of these hypotheses as they were already confirmed and accepted by the mainstream scientific community, which is not the case. For example, the title of the article, “New research puts age of universe”, that is pure clickbait, the correct tense is, being very generous, “could put”.
And when this happens in a field like cosmology, it’s relatively harmless. But the same happens in fields that have a more direct impact in the general public’s life, like the usual “a couple of years ago they said eggs were unhealthy, and now they say we should eat 5 per day”. And the effect is that people stop trusting the recommendations of the experts.
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.
I’m not surprised at all honestly
It sounds insane to say, but 13.4 or whatever felt way too young
“Feels” and “common sense”means little in science unless you have a mathematical or logical reason why you feel that way. I’ve seen far too many metaphysical theories try to be taken seriously to not point out that “feels” is useless, observation and math are what matter
And yet, some of the greatest scientific discoveries of all time were made based on people’s feelings and intuition. Fucking shocker I know right. I’ll bet you’re fun at parties.
Despite agreeing with your initial position, you sound like an asshole at parties and outside of them, too. If you need to posture and belittle to support your position, then you have no business trying to argue it in the first place.
Intuition can be a powerful compass to guide us to truths we haven’t yet considered, bubbling up from our subconscious that contains the bulk of our brain’s processing power. But the other commenter is right, it’s not infallible. That same intuition in different people came up with all of science’s knowledge (both the stuff that is currently believed and the stuff that has since been disproven) as well as all of religion’s knowledge (assuming there isn’t any higher being involved, which my intuition says there isn’t but others’ have come to different conclusions).

Okay, but the universe and our galaxy is really friggin’ big. There very well could be other life out there, but is it intelligent enough to build spaceships? Perhaps. Has it figured out how to traverse the galaxy in a reasonable amount of time? I have doubts about that. Then what’s the chance it would came across our own solar system? Pretty slim.
A sincere thank you for a fascinating, quality post in Technology instead of the usual Threads/Twitter/Reddit posts.
