Thoughts on Dance

This article is a little out of context here (Gareth Vile, editor of The Shimmy had asked his writers to challenge each other on theoretical approaches to dance) and the argument was developed so I could fit in stuff from the 2010 Edinburgh Festival. BUT I still think there’s something in this approach. In my rush at the time I didn’t check the Wittgenstein quote properly: “the face is the picture of the human soul” is correct, but he also said “the body is the picture of the human soul” which fits ever better.

Goldilocks Earth

After 700 million years the meteor bombardments that created the Earth slowed down. The Moon was originally a lot closer to Earth. (It is still moving away.)

The Earth’s tilt moderates the temperature across the whole planet. The tilt is held stable due to the exceptionally large moon.

The combination of land and and sea allows the carbon cycle to regulate the planet’s temperature.

Without a biological ecosystem, free oxygen would disappear: oxidizing surface materials or forming nitric acid.

Free oxygen on Earth forms ozone. Which protects animals from from UV radiation.

Water is the 3rd most plentiful material in the universe. It came to Earth in meteorites and comets. (Back to the first line.)

Time

Earth is 4.5 billion years old.
Life has existed for the last 3.4 billion years.
It is predicted the last animals will disappear in less than half a billion years from now. Life (diversity) on Earth is already in decline.

If 4.5 billion years was a 24-hour clock, then:

  • Complex life (Cambrian) doesn’t start until 22:00 hrs.
  • Dinosaurs start at 23:00 hrs.
  • – And Homo Sapiens have existed for 2 seconds.

Or

If 4.5 billion years was a mountain as high as Everest.  My life is the height of the last snowflake at the top of the summit.
