13,6 Billion years ago

[octave]

The first picture from the James Webb Space Telescope.    This area of sky  is the size that one grain of sand held at arms length would cover.     This light began its journey 13 billion years ago which is stunning given the universe is only 13.7 billion years old.

Until now, no one has seen such views.  This is science. Priceless, if you think about it.

  Today you can see the highest achievement of mankind contrasted with the opposite  degrading inhumanity in Ukraine. The two biggest news items of the day. Nev

I would just love for Australia to welcome and financially reward such wonderful stuff.

Is it in any way, orinantated towards Earth !.  Or the opposite.

I rather suspect, Spacey, that the Webb telescope is facing away from us. Otherwise the view might be spoilt by a rather big lump of rock. (Third rock from the sun)

 

And by the glare from the sun coming around it.

[Bruce Tuncks]

That picture shows the universe well before Earth formed. I think they would have been first generation stars. So their planets would have lacked elements that we require.

Some of those first generation stars exploded in supernovas and this made the elements we need, so only second-generation stars would have had heavy elements in them and therefore their planets.  The dust from supernovas would finally coalesce into second-generation stars.

So, you reckon I’m second-hand?

An Exo planet 1150 years away has been detected and it most likely has H2O.

Recycled more precisely. Evolved as well. That's enough to explain it all. (why you are here etc).  SOoo much time for al the changes  Nev

[Yenn]

What happens when the telescope looks back and sees before the start? Will it just be black?

Rather like looking back when you exceed the speed of light and can see yourself coming.

 I have no wish to see myself coming, lets just leave the light off.

You mean you don't have a ceiling mirror?

[nomadpete]

At my age, the ceiling mirror just put me right off so I had to rid of it.

Some of your molecules were once T-Rex urine.  Second hand doesn't begin to describe it.

[Jerry_Atrick]

These days using the first hand is tiring enough to think of

So sex is 'all in the mind'

 

But one thing hasn't changed. I still fall asleep right after it

[Bruce Tuncks]

You name it, some of our molecules once resided there...  Hitler, Pharaohs, and yes T-rex.

Maybe we should be buddhists, on account of how they preach of the interconnectedness of all life, which the buddha figured out without knowing about atoms. Darn, they believe in reincarnation, obviously nonsense...

[nomadpete]

You can't quite say that your personal atoms have been in existence for 13.5 billion years.

Because electricity moves electrons from atom to atom. So the atoms themselves are not made of the same bits that they got at the big bang. But our atomic makeup is basically that old. Further to that thought, our cellular makeup is constantly renewing itself and discarding old cells during our brief life. So, each morning we are not quite the same person that we were when we went to sleep.

 

Cool, huh?

Electrons (orbitting) have little mass compared with the Protons and neutrons in the nucleus. The only way to destroy mass is by nuclear reactions where energy replaces mass. E= MC squared. Some of the larger atoms are unstable and decay emitting rays.(radioactive). Nev

Iron ore, l was told came from sea creatures,

They were born, they died, they were reborn as slimy mud, only to die again !.

" ahh such is life ".

The earth's core is made of Iron and nickel. Metal not oxides. That's why it's magnetic and we are protected from cosmic rays.  Nev

So I can tell the missus that I’m not the same bloke she’s angry at for stuffing up yesterday?

[Bruce Tuncks]

Yep, apparently we don't have molecules for more than 7 years. So you are certainly not the man you used to be...

Actually, I knew that anyway. getting old is a bugger I reckon.
