Electrons and Yellowstone National Park both struggle with a similar problem. By observation, the thing you wish to observe is changed.
I was struck while reading something in which a character considers traveling to several different cultures, to experience their unique characteristics. He was visiting localized cultures, physical land areas in which the people live in a certain way, with specific traditions and behaviors. This character also lives in a future of instantaneous travel from one point to another, across dozens of worlds - all of these cultures he visits exists in a framework where every other culture is easily available. We have a similar situation here and now in the real world. More and more, the artifacts, ideas, music and food of distant localities is available to us. Right here in Oregon, I can buy sushi, durian fruit, brie, Ethiopian coffee, and lichee flavored Chinese black tea. Immigrants have brought with them the flavors of their old world, and commerce takes care of the rest.
