err...a star last like 5 billion years and umm...the universe is 14 billion years old...so, are we on our 3rd generation star formations?
Considering average star formation/destruction.
Exactly, when do galaxies start forming, during the first generation stars? So, what came first, the stars or the galaxies in which they lie?
I don't recall any stars hanging out in the middle of nowhere going either poof-I'm here or boom-I'm outta here, outside of some galactic formation.
So, are stars the product of Galaxy formation?
Exactly how many stars had to blow up in the general vicinity to create the heavier elements to re-join again into a 1 pound Iron meteorite that blasted its way into the earths atmosphere and landed at my feet?
Considering the vast distances that stars are from one another. Wouldn't the explosion of a large star over a several light-year radius dissipate into rather nothingness?
Didn't it take 4 billion years to create out solar system from this dust?
But, wasn't all this stuff already here prior to that?
There seems to be; a time frame issue,"How long does it take a solar system make," or a density issue of "How much stuff is really between stars?"
or between one's ears :P
I confused :/
