Project leader Loretta Dunne added: "The origin of cosmic dust is, in fact, the basic question of the origin of our planet and others.
"Effectively, we live on a very large collection of cosmic dust grains and yet, until now, we have not been sure where cosmic dust is made." Cosmic dust consists of tiny particles of solid material floating around in the space between the stars, but unlike house dust, it more closely resembles cigarette smoke and blocks out half of the light given off by stars and galaxies.
"Now studies have shown that there is dust right at the edge of the Universe in the earliest stars and galaxies; we realise that we are ignorant of even its basic origin."
see , scientist say we are ignorant of even its bisic origin
it's very clear that they know nothing befor this dust (smoke)
Very first sentence of the article:
"n the latest issue of the science journal Nature, they explain how they have found that some supernovae, or exploding stars, belch out huge quantities of this dust."
That is why, in the passage you quoted, Loretta also gives the statement "untill now" in what she says.
The article states that we do not know the precise origin of this dust (not smoke, I see you have problems with the english language but the sentence "more like cigarette smoke" does not mean it is smoke, but that it resembles it). We do not need to know that to know the first stages of the universe however, since in those first stages this dust does not exist. The only thing that existed than were hydrogen and helium, which form starts. Only after these elements fused in those stars and those stars exploded, could this cosmic dust be a part of the universe.
So again, no, the article really does not deal with the origin of the universe.
