Astronomy questions, help?

It is completely reasonable to expect any physical alien contact that is made by overcoming the extreme barriers of distance and time in the universe to be entirely technological. The kind of technology that yields space travel will very likely be tied to some form of economics, and economics asks any civilization (earthbound or alien) to find the cheapest way of solving problems. Remote controlled machines are cheaper than sending living individuals, and autonomous machines would be even cheaper.

There actually are some fascinating fictional examples of alien creatures that are fairly what you describe. A principal character in a great novel called 'Ilium' (author, Dan Simmons) is a member of a mechanical race that does not age and has outlived humanity. The best example is described in a novel called 'Spin,' (by Robert Charles Wilson), but going into too much detail would ruin the book.

There are actually some non-fictional examples as well. One of the robotic Voyager probes, sent by Nasa in 1977, actually contains mechanical and robotic means of communicating with potential aliens it might encounter. Of course, in this case the robot is quite primitive, and our robot would be the "alien" to whatever civilization it stumbled upon.

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.
