A U of T scientist has found unexpectedly young material in meteorites, a discovery that breaks open current theory on the earliest events of the solar system.

Didn't see the actual age provided for the chondrules?

I presume that stuff continued to crash together sometimes even after the intial bodies were formed. We only need to look at Earth's Moon for evidence of an example. Unless these chondrules are billion years or more younger than our Moon?

Instead they seem to have formed 5 million years later from material generated by collisions between planet-sized objects in the early Solar System.

So, meteors aren't really extraterrestrial visitors; they're just coming home!

(Well, some of them, at least.)

(Bold mine): so instead of 4.3 billion years old, they are 4.295 billion years old? I guess that he meant something like 500 million years, because they aren't able to date that accurate...
