Movie 10 (1:19)
Script : Accelerating,
we see the distortion increasing, and the sun and clouds rotating
into our field of view. The rectangle in the center of the screen
is a computer correction which leaves out Doppler and intensity
effects to improve clarity.
To see what is
happening all around us, we use a mercator projection; a map of
everything we can see around us. The map is made by "unwrapping"
a sphere and stretching the areas at the poles to make the map
flat. This is the same kind of common map of the Earth that shows
Greenland stretched to the size of South America. This kind of
map obviously creates distortions of its own which have nothing
to do with relativity. But using this view may help you to understand
the abberation effects of relativity.
Accelerating, we
can see that objects behind us increase in size. Even though we
are moving away from the houses at the end of the street, at the
left and right edges, the houses grow larger. The patch of blue
sky overhead shrinks to a small circle ahead of us. And the clouds
and sun rotate into that small circle, appearing distorted but
maintaining their positions in the shrunken scene.
