Why night is dark? 3

The 'Egyptian Museum' in Cairo, which is super famous for Tutankhamen, is a historic museum opened in 1902 and boast of the world-top Egyptological exhibits, however the museum becomes too small for collections having been increased in an accelerated speed after its opening, and such activities as conservation, restoration and research, which are important functions for a museum, are getting inconvenient.

Hence, the Egyptian government has decided to construct the 'Grand Egyptian Museum (GEM)' in the Giza area which has been tourist attractions with pyramids and a sphinx and started making a plan in 1994. A project team consisting of the best from all over the world has been continuing energetic activities aiming at the opening in 2010. After the completion the GEM will become a museum which boasts of the world top class scale and contents exceeding the British Museum in London, the Louvre in Paris and the Metropolitan Museum in New York.


As I have been involved in the exhibition planning of the National Museum in Jordan, my participation into this project was decide in a hurry, although my participation this time is a short period less than a half year. The preparation was so busy that I had lost time to write a blog. I am now writing this blog in Cairo.

Therefore, I have to write 'The genuine and the real 2' properly, however for a slight change, I would like to write a sequel to 'Why night is dark?'.

Though a story becomes a little bit solid, please bend an ear to the story flying your feeling into a boundless and eternal universe;

The current cosmology says that the number of stars is invariable looking from the whole universal scale, although if we look at the whole universe stars are dying out of and coming into the universe every second. However averaging the total number it is still invariable, it is said. I'll be at a loss for answer to a question to me 'why?'

It is also said that scale stars are equally distributed looming from the whole universal scale. There are nebulas like the galaxy to which our solar system belongs or groups of nebulas, hence there are space where stars are so crowded and space where few stars exist if we observe them individually. However, the whole stars are equally distributed, it is said. I recommend someone who has a question 'why?' to read a guide to the cosmology.

Furthermore, this is one of the keys to the question 'why night is dark?', there is tremendous number, almost infinite, of stars in the whole universe, it is said. A story on the universe has no way out without saying so, I expect you to feel 'Well, I've never been to the universe but it is such a place'. Although our earth is part of the universe.

As the brightness of light is in inverse proportion to a square of distance, it might be sensuously understood that in the daytime when the sun shines it is bright and shadows exist around us, however it can not theoretically explain why night becomes dark completely.

That is to say, even though the sun is so much powerful to the earth, if we aggregate light of infinite stars which ubiquitously exist in the whole universe, the light becomes the same as the sun's light. This is a mysterious secret in the 'infinitive', though we, who live in the 'definitive' world, can not feel it natural, I presume.

Well, please look forward to the next. In the next time, I'll be sure to announce that 'answer judged as the correct answer', either from Cairo or Tokyo, or even from Amman, 'Insha 'llah'
