Wikipedia gives the next definition of culture: "Culture (from the Latin cultura stemming from colere, meaning "to cultivate,") generally refers to patterns of human activity and the symbolic structures that give such activities significance and importance. Cultures can be "understood as systems of symbols and meanings that even their creators contest, that lack fixed boundaries, that are constantly in flux, and that interact and compete with one another". Different definitions of "culture" reflect different theoretical bases for understanding, or criteria for evaluating, human activity."

But we have other word combinations with "culture", "virus culture" for example. Cultivated group of bacteria, so to say "civilized", organized into some form of order to exists and to develop its genes into new forms to survive and to grow. Difficult not to remember the words of agent Smith from the film "Matrix": "Humans are a virus". In the film he goes on that humans "like a cancer for this planet".

I couldn't find the answer for myself, as what can be seen from the plane (asphalt-paved roads, smog and mountains of trash) somehow can remind the target affected organ surface. We won't speak about other damages to the planet (nuclear explosions, chemical disasters, etc). Humans DO REMIND a virus.

Bacterium as people can be good and bad. Good ones improve the organism condition. Cultures are different too.

Some scientists think dolphins originally were on land millions of years ago. When they moved into the water, it was hard to catch fish. The nose was like ours. It was right on the front of their head. When there is a fish near them, and the dolphin has to breathe, it has to lift it's head up. In doing so, it can't keep its eye on the fish, and the fish swims away. Over time, the blowhole moved to the top of its head. Now, when it has to breathe, it just lifts its head a little up, and its eye is still on the fish!

Interesting to know that this world is not the only one. Scientists now believe there may really be a parallel universe - in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes exist less than one millimetre away from us. In fact, our gravity is just a weak signal leaking out of another universe into ours.

It all started when superstring theory, hyperspace and dark matter made physicists realise that the three dimensions we thought described the Universe weren't enough. There are actually 11 dimensions. By the time they had finished they'd come to the conclusion that our Universe is just one bubble among an infinite number of membranous bubbles which ripple as they wobble through the eleventh dimension.

Alongside comes the idea that these "parallel universes" can be human-created computer worlds, like Second Life or Counter-Strike. According to the scientists, even book and film heroes "live" in these book and film worlds "led by the godlike imagination of their creators - writers and film directors". Remember "Last Action Hero" with Arnold Schwarzenegger, when a boy came into the film world and acted like a hero?

Scientists are right. There are countless worlds we live and even more we can't imagine, but somehow can influence them. We CAN create them!
