Theoretically...

If I were traveling at or 99.999999999999999etc% the speed of light, and turned on a flashlight, what would the result be if....

1. I turned it on toward a wall in my direction of travel?

2. I turned it on toward a wall behind me?

3. I shone it out the window of my craft? (Would it appear to bend in one direction or another?)

4. I shone it toward the floor?

And what would an outside observer see?
