A student has solved what will be one of the biggest problems facing the human race in the next 100 years: How we'll look when we inevitably conquer the galaxy. To help avoid any inevitable arguments between nations, student Oskar Pernefeldt has designed "The International Flag of Planet Earth".
What could the flag of the planet earth look like? Would it illustrate the planet itself? Or is it a symbol of the inhabitants of earth - a reminder that we should all stand united. Celebrate life itself. Remind us that all life is connected in one way or another. But life wouldn't be possible without the water on earth. Therefore it would be relevant for the blue planets flag to be blue. But what kind of blue? A flag like this would mainly be used while representing earth in outer space. It should be a clear contrast to the black of outer space. Also to the white of the space suits and shuttles which it would be placed upon. Light blue would disappear into the white and dark blue would disappear into the black. Therefore a brighter blue would be more fitting.
There are a lot of different ratios or proportions for flags. A few of them would be conceptually interesting for a flag like this. For example the one to one ratio is a perfect square, fitting a circle or a planet if you will. Five to eight is the golden ratio, a mathematical ratio that occurs in lots of mystical ways in nature. The most common flag ratio in the world is the two to three ratio.
All of these options were taken into consideration during the design process of the international flag of planet earth. Resulting in a flag that reminds us to take care of each other and the planet we live on.
