Phys org makes a lot out of this.
In a nutshell a far away galaxy considered to be young by astronmocal standards has an oxygen signature (something I as a terrestrial chemist wouldn't denote "complex chemistry"😉.
So a long standing hypothesis about the formation of oxygen in the standard model has been disproved and a new one needs to go up instead.
@Ponderable
Well, I wouldn't say it has been disproven. They are looking at the spectrographic profile of a dot after all.
And in the modern world there is a rush to publish scientific finding as soon as possible, without necessarily going through proper verification. So I treat published findings with a high degree of scepticism, until others minds cleverer than my own have reviewed them.
I still read them, as there is a lot of interesting stuff being found.
But there are many mysteries emerging from the most distant observations. Such as the earliest galaxies either being gigantic or tiny, with nothing in-between.
And there is the observation of galaxies with inexplicably high brightness, with the light profile matching stars, not feeding black holes (which is what Quasars are). Which implies a concentration of stars that makes no sense.
It seems the early universe was even stranger than we thought and a lot more observations need to be gathered to work out what was going on.
@Wyn-Davies saidI fully agree that the universe has many more wonders to reveal.

The hypothesis I talked about was that we need a few hundred misslion yers to obtain a heavy enough star that Helium burning can proceed, which is the currently most highly favoured theory for the creation of Carbon (and succesively oxygen) from Helium.
However predictions on the behaviour of the very early universe are of course extremely difficult (though physics is reasonably sure about the creation of the He/H-relation from the first roughly 100 s after the big bang.
@Ponderable saidMy wish list says the reason those well developed galaxies exist is because our universe bumped into another universe and some stuff, some galaxies for instance, changed places.

Now if THAT were proven or decent evidence shown, that finding would suggest that other universe would have to have laws of physics VERY close to ours, like C being what it is and not a Km per second slower and the like.
Of COURE all hypothesis and conjecture but there are some unexplained oddities in the CMB.
