In each of those examples light is moving between atmospheric regions with different densities, which have different refractive properties. In general, light moves in a straight line through an atmosphere. You don't see headlights twinkling on the highway or the light from your monitor breaking into the spectrum on its way to your eyes. This is because in general there are no extreme differences in density between regions of an atmosphere. Light only bends when it transitions between mediums; there is no medium that bends light in and of itself.
No, that's mostly wrong, and you completely failed to explain the blue sky or sunrise/sunset, there are no density differences in play there.

As for your no-twinkle examples, the lights DO "twinkle", it's just that our eyes cannot perceive it in many situations. (Nor is it a concern in typical applications/situations.)

Finally, there is no tangible medium that does NOT bend light in and of itself.

What's the speed of light in a vacuum? What's the speed of light in a air? Why are they different?

When you wish upon a star
makes no difference where you are
at the event horizon
lasers will bend

I didn't fail to explain them. I didn't try to explain them.

Is "bend" a synonym for "slow down?" What are you talking about?

Why do I find Tweedy V. ASID such compelling television?

Oh well, beats Dancing with the Stars...

Even more fun. Light beams will actually orbit. ♥♥♥ :)

Of course not. But you can't have one without the other. The same mechanism is responsible for both (at least the kind of bending and slowing we've discussed so far).
