Ok, so the heavier elements were all supposedly made in other stars, to be ejected when they went supernova, which is why newer stars have more of said content.

Question:
Why don't we see this hurtling through our solar system? Shouldn't we see an equal amount of mass per unit time passing through on its way to other stellar nurseries as our own solar system captured during its formation?
