The technique used by Kepler does require line-of-sight. If a particular planet does not pass between the star and the telescope, then it will not be detected. There are several different techniques for detecting stars, each with their own advantages and limitations.
This is one of the limitations of the technique used by Kepler.
Bob is right, Unless the orbit of the planet is in our line of sight it will not be detected. Only about 2% of planets line up like this so the 1500 planets discovered (700 confirmed) by kepler suggest that it has missed 75000 planets. There must be a LOT of planets out there.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
