I've been reading about the movie (didn't read the book) and I am so confused how quickly they found a solution to the astrophage. Rocky and Grace meet outside the not-dimming star to find out why and get a solution. Then they both zip-zap to the planet that the astrophage is coming from and collect astrophage. And find microorganisms and there is the solution!! Can someone explain this to me more? I still don't understand why one star wasn't dimming. Did Grace collect astrophage from ONLY the line that was going to that star? Are the micro organisms living on the astrophage planet or on the star?

Also, wouldnt humans want to keep some astrophage alive to use as a power source? They are still living and could be useful?
