Assume that this earth is celestially equivalent to ours: e.g. same solar system, same position, same orbit, etc.
Would the sunset look similar to ours on a floating-island earth?
The earth itself is essentially masses of land orbiting in stasis around a fixed "center". Each is spherically shaped and large enough to hold about 500 people comfortably, but spread out from other islands so that one can narrowly see one island from another.
There is no land mass in the center of the earth. (This would cause other scientific problems, but for the moment I'm overlooking those; and besides, those problems have been addressed in other questions.)
My question is, scientifically, would a sunset on this earth look similar to our sunset? Specifically, would it scatter as much as our sunsets do? How long would it be?
