How old is 3% of the age of the universe?

[foxidrive]

That's the age of the youngest galaxy seen so far.

One of the holy grails of cosmology is to measure, directly, exactly when the first stars and galaxies formed in our Universe. The Hubble Space Telescope has been pushing the distance record farther and farther back, with its measurements typically confirmed by ground-based, spectroscopic follow-ups. This time, however, the new record-holder was so distant that confirmation needed to be done from space: by Hubble itself. The result? A galaxy at a redshift of z=11.1, from when the Universe was just 400 million years old, or a mere 3% of its current age. This is a record that will likely stand until the James Webb Space Telescope launches, as it took a combination of incredible work and incredible luck to find a galaxy this far back with our current technology.

The Universe???
That's a very brave guess...I guess.
(The known Universe would fit)

 

[TeeEm]

Nobody will ever know because the way many people think that there has to be a beginning and an end to everything which in this case from the "experts" knowledge of the "known" Universe is virtually impossible because of the sheer scale of time and distance from earth, assuming of course that there is a beginning and an end. ( Which I very much doubt. ) We are not at the center of any Universe or anywhere for that matter, even though there are many people in our society that think that they are.

+1 doubt from me TeeEm.
No one would ever figure out that and for how long is it there with those restrictions.

 

[aye-aye-Chris]

If they can show expansion, or whatever of the 'known' universe, can they not calculate from whence it came? This... dot. The... point of the [cough] biggus bangus.

I'm still of the opinion that the biggus bangus was merely another super nova and we (The [cough] Milky Way) were either part of the result or now mixed up in it's expansion

...or maybe we all live in the bottom of a black hole... and no American presidents are involved here.

There's string theory and associated membranes - it's all theory and none of us is going to know one way or the other by the time we mosey off our mortal coils.

Nobody will ever know

The thing that is mind boggling is how everything is so far away, and so huge.

1 anna half minutes - worth a quick watch!

 

[misi]

As soon as someone with brain from the scientists accepts that there is no time in the Universe, guessing how old it is will be easier.
To throw away the Theory of Relativity because of that? No way.
Well it will take a long time to happen.

 

[misi]

1 anna half minutes - worth a quick watch!

Yes it is worth.
A billion times larger than our Sun...

 

[foxidrive]

No time, misi, or just huge time frames for things to happen?

Just giving the terms some thought, Chris, a super nova is a big star going boom.
The Milky Way is a galaxy with a ginormous number of stars inside, with some going super nova every so often.

Is super nova the term you meant to use?

 

[misi]

No time, misi, or just huge time frames for things to happen?

When did it start? When would it end?
The Universe known by us today might disappear tomorrow.
Would it mean the end of time? Time is infinite. If our clock would survive it, it would be still ticking somewhere- today known as nowhere.

Where is the beginning and end of the Universe?
There isn't such thing.
Somehow it's infinite just as time is.

We are not at the center of any Universe or anywhere for that matter, even though there are many people in our society that think that they are.

Here I have to disagree with TeeEm.
I'm in the center, Kilometers away you are in the center, TeeEm hundreds-thousands of Kilometers away is in the center and something hundreds of million-billion-trillion light-years away is exactly in the center.

How is it possible?
For our brain it's impossible to figure out because we cannot see it from the outside, ever.

Should I try to figure out how is it possible?
Not going to.

I accept that time-distance exists in our little World* as long as I'm alive.

*Not equal to Universe.

 

[foxidrive]

That's discussing the nature of time, but as I see it, to me or you it's subjective. We feel time passing as we do things, and it's quick at times and drags at other times.

Einstein talks about space-time in his theories - but if there was no universe then there'd be nobody to notice the passage of time anyway.

 

[TeeEm]

I'm in the center, Kilometers away you are in the center, TeeEm hundreds-thousands of Kilometers away is in the center and something hundreds of million-billion-trillion light-years away is exactly in the center..

Sigh.

A science show once gave the factoid that if you head out in one direction into the Universe then curvature of space-time means you'd come back from behind yourself - assuming you live that long.

If you do it fast enough then with a little luck you will be able to catch yourself from behind.

Is super nova the term you meant to use?

Yup (pedant: super nova / supernova)

A supernova is the explosion of a star. It is the largest explosion that takes place in space.

On another note:

Our sun is a middle ages lower mass star in our galaxy it has been happily burning through its supply hydrogen for billions of years. Scientists believe that 5 billion years in the future our suns supply of hydrogen fuel will run out.

Did he say 5 MILLION years????

No, he said 5 BILLION years in the future

Phew! That's a relief. I was worried there.

Yes, we can plan ahead to survive that event.

 

[foxidrive]

Yup

It's a big boom alright - those image of the light echos show an area that's so effing huge.

What I'm trying to grasp is how Mr Milky Way is part of the result and your thoughts on that, as what occurs to me is that the supernova is an exceedingly tiny part of the Milky Way.

Biggus Bangus is thought to be the creation of the universe. I reckons it was a Humungous Bangus in an even huger Humungouser Universe.

I'm still of the opinion that the biggus bangus was merely another super nova and we (The [cough] Milky Way) were either part of the result or now mixed up in it's expansion

Part of the result is obvious with popular opinion, as in what they think happened/is happening.

Mixed up in it's expansion is demonstrated by one addition to an image I posted above.



My edited and opinionated image only, I couldn't add the milky way into all images quickly but please imagine it in the same position amongst the dust in each image of the Supernova depicted.

So our Milky Way either was a part of the universe as a result of, or already there as the Supernova blasted the expanding universe towards and past us. Is the Milky Way expanding? Hrrrm.

 

[foxidrive]

Hmmm. Does that indicate our universe was created by a big boom/big supernova in a larger universe? Where are we now in relation to the larger universe? Is our universe merely a portion of an even larger universe?

My edited and opinionated image only, I couldn't add the milky way into all images quickly but please imagine it in the same position amongst the dust in each image of the Supernova depicted.

Nice editing... my questioning mind wonders about the scale of those two things though. I comment on that because a supernova is the death of a star, and the Milky Way has around 100 to 400 Billion stars inside it.
