maybe light pollution has affected the sky. are you sure it's only one of them?

based on what we know about life and evolution, wouldn't it be impossible for us to be the only life on the universe?

why not add a tail to the B2? wouldn't it fly better?

i'm still a high school student, so i'm not sure if I want to go on to study astronomy or aerospace engineering. could someone please point out to me what are the main advantages of each profession and the specific skills I would need to be sucessful in either one.

what about a slow airplane, let's say a regular single-engine cessna. if the tail fins fall off during flight, is it still able to keep flying? in that matter, if I were to remove the feathers in the back of an arrow, it wouldn't fly straight, so the same thing would happen to an airplane right?

is the tail essential for flight? if you were to remove the tail fins from an airplane, it wouldn't be able to change direction, but would it still be able to stay in the air?

in airplanes, what are verical and horizontal stabilizers for? is it only for changing direction with elevators and a rudder, or can they do something that the wings can't?
