Luz: a Solar seria a Luz Natural na sua terceira geração?

( Texto obtido no forum com link abaixo. para pesquisar se esta informação está correta.)

This sun is a 3rd generation sun. We know this because of the quantity of heavy metals. The universe is about 13.8 billion years old, so divide by 3 … About 4.5 billion each, round up to 5. Actually the first two generations probably formed faster, as with each supernova the elements get spread out further. The first one formed pretty fast due to clumpy matter. Anywho that combined with the paleontological record … It’s all pretty much done with huge assumptions so it’s more like +/- 1 or 2 billion years.
