Yes, I know that. What was your point? These particles are plentiful in the earth's mantle according to the article, but these particles are in "pristine" condition since they haven't interacted much with other matter. Their age suggests that a supernova explosion and it's remnants could easily be the stuff of which this solar system is made of. Gravity, and the laws of gravity would suggest the heaviest materials would be in the sun and the largest bodies to form first. |
Michael,
You quote a reference but don't understand it's context The olivine in the earth are chemically different than the particles that were collected!
Quote:
Results showed that the olivine doesn't come from anywhere in our solar system, plentiful as olivine is in our solar system. "Olivine, which includes gem-quality peridot, is a very common mineral in meteorites and makes up the bulk of the mantle of the Earth," Lauretta said. "That's why it's been so hard to identify olivine that came in from another star system."
"The supernova grains have oxygen isotopic ratios that have never been seen before in meteorites or comet dust, but are predicted in astrophysical models of supernova explosions," Messenger said.

You see there's olivine in the earth's mantle and assume it must have come from the supernova explosion the article talks about. There are other processes beyond supernovae that can form olivine.
