I have an idea: replace debug information on the loading window with some random quotes of a famous astronomers, scientists, philosophers about Universe and science. Examples:
I have deep faith that the principle of the universe will be beautiful and simple. - Albert Einstein
Imagination will often carry us to worlds that never were. But without it we go nowhere. - Carl Sagan
Science is a way of thinking much more than it is a body of knowledge. - Carl Sagan
Astronomy compels the soul to look upward, and leads us from this world to another. - Plato
The purpose of life is the investigation of the Sun, the Moon, and the heavens. - Anaxagoras
So, type here quotes you like or found in the internet. We can make a poll later on, to choose few dozens of them. Keep in mind that all quotes must be translated into other languages supported by SE (they are probably will be stored in the localization files). It's important to find an 'official' translations, so if you are not from US, GB and other English-speaking country, post the translated version of the quote as well (and don't forgot to type what language is it).
