"Z" is for Zebras (part 3)
The black one ? Or, the white one ? This experiment was actually carried out on the ISS by astronauts.
If you thought "black", well then, that is correct and the reason is that "black" is stark, strong and solid in appearance. This creates the illusion of weight. The balck ball would seem to be heavier than the white ball. So, to the astronaut, floating around in a weightless state (condition), the black clored ball has more appeal, in that it represents "gravity", which is found on the earth, our home.
So, how does this relate to zebra stripes ? Well, the three adjectives used above to describe "black" play an important role in determining why most humans think the black stripes came first on a zebra.
"Stark", "strong" and "solid", offer something of substance to the human mind, something to grab on to "white" has a soft image, something light, fluffy, like the clouds. We can't reach out and grab a cloud ! (V.C)
