Or does it “smack” of difference?

Light rays too must follow geodesics in space-time. Again, the fact that space is curved means that light no longer appears to travel in straight lines in space. So general relativity predicts that light should be bent by gravitational fields. For example, the theory predicts that the light cones of points near the sun would be slightly bent inward, on account of the mass of the sun. This means that light from a distant star that happened to pass near the sun would be deflected through a small angle, causing the star to appear in a different position to an observer on the earth (Fig. 2.9). Of course, if the light from the star always passed close to the sun, we would not be able to tell whether the light was being deflected or if instead the star was really where we see it. However, as the earth orbits around the sun, different stars appear to pass behind the sun and have their light deflected. They therefore change their apparent position relative to other stars.

- Stephen Hawking, 1988, A Brief History of Time

Stephen Hawking wrote about time and distance. This song is also about time and distance.

It’s called The Far Away Song.

(Fig. 2.9)

P.S.
I’m now using the name Fantastic Invader for some music.

This is the second Fantastic Invader song.
