Hi.

I was under the impression that the generally accepted age of the universe was 17 Billion years old. Lately however , every article I've read about the universe, seems to suggest it is +/- 13 Billion years old.

Can anyone tell me when the new age was agreed upon ?

thanks

perhaps you are reading old articles?

The current article's I'm reading were probably written less than 1 week ago. Thus I assume you're saying article's claiming the Universe in 17 Billion years old, are old. That's sorta what I was implying. Any idea when it became generally acceptable (or more likely) that it is 13 Billion years old ?

cheers

I think he was suggesting that the articles claiming the universe is 13 billion years old were themselves 4 billion years old...😵

I sorta suspected that. However I was actually looking for an actual answer instead of ' thats colour is so last year ! '

Before I went on holiday last year (granted for 2 months) there was still plenty of people (on forums) referring to 17 Bil years as the age.

any idea ?

EDIT: I suppose I should have looked at google to start off with, just difficult to know what the most commonly accepted '95% sure, its science afterall 🙂' age is..

Type A supernovas all have a distinct energy signature. By looking further and further backward and comparing their brightness... we are able to build a chart that says how "old" an object is. It is using these values that has most recently done two major things to our understanding of size and scale. We ( no... i don't got a tur* in my pocket) now think that the universe is between 12.7 and 13.4 billion years old ... and we now know that the universe is accellerating into expansion, instead of slowing down over time. Whatever is happening in our universe... we are still an infant.

Ok, but this is the thing that is confusing me. Do we really have any clue ? Other than Einsteins theories (which I'll grant as accurate to a certain extent) as he actually managed to predict certain events , how can a layman (that' s me 😉 ) actually believe in all that .. the universe is x amount of years old when various scientists contantly disputes various findings ?

Had I said 2 years ago the universe was 13 Billion years old, I would be made fun at, as everyone with any intelligence knows its 17 ?

As for constant expansion of the universe, you use the word 'know' , however in the last month I have read numerous articles disputing even that belief. We have Dark matter, Dark Energy and Dark chocolate and it seems with the exception of the latter, no-one really understands it .

Time to ask Zaphod I suppose 😉

WHO CARES WHAT DIFFERENCE DOES IT MAKE IN ANYONES LIFE. DO YOU HONESTLY LIE AWAKE AT NIGHT WONDERING WHERE 4 BILLION YEARS HAVE GONE. Worry about what difference you can make in the world in your lifetime 😲😲😲😲😲😲😲😲😲😲😲😲😲😲

Or ask "Zirk" just before you take him to your leader.😵

You are right in being confused. As "testing" continues, there arise argument and debate. This is the crux of science. There are many possiblilites at this point. The truth is that we probably have not yet identified the correct questions to ask.

On a side trip into possibilities... the idea of Quantum Mind actually allows for "past becoming future" in the sense of perceptional registry. That simply means that "all you know" comes from the past. Is the past real? Where and when and why is it then? All you will ever have is "now". Big time.

Age and time really lose much of their meaning when in exact truth... a photon that leaves your flashlight "now" arrives at the edge of the universe... from IT'S POINT OF VIEW, without the lapse of a single second. It is at the speed of light where time doesn't exist. You are 22.4 billion years dead, taking into account the rate of expansion of our CURRENT UNIVERSE.

Yea. As to using "Know"... dumb. We actually "Know" very little. But we are able to test and discard. That will eventually get us to the truth. If we can stand the taste of it when we get there.

Hehe, Star, I think I understood some words in there and got the general jest of it all, but thats about it !

Problem is that you pretty much need supremely highly sophisticated equipment just to be able to measure what happens in the galaxy and on top of that a degree in astrophysics it seems.

Atleast chess is sorta simple 🙂

grimace!

I really have a hard time with chess. I am not good at it and it destroys my ego. So I don't play.

😕🙄

The answers of the universe will most likely never be revealed. You can only guess. Maybe one day years from now our technology will be able to prove these theories. That is if man still exists. I'll be long dead anyways so I'm not gonna beat myself up over it
