Maxims:

1. The principle(or say, the universe, the God) does everything for nothing.
道 常 无 为 而 无 不 为。
2. One will only be great if he never struggles for being great.
以 其 终 不 自 为 大 ， 故 能 成 其 大。
3. The spirit (or say idea) may be accepted over the world without the body's travelling around.
足 不 出 户 而 道 行 于 千 里 之 外。

 
Wisdom is born on a planet. However, wisdom will finally take a born from the womb of the mother planet, and sets steps into the universe. So do we human being on the earth. And this will happen within several hundred years.
Critical Questions and Answers"
Q:Why don't you consider the chance of future nuclear war which will destroy anything we have?
A:I really do not think that this will finally happen. The key reason is that no country can provide all daily use product to its people without proper international trades. And the percentage of international trading is increasing in the daily purchasing list of every body. Who want to risk that most of its people will suffer lack of basic products if a conflict can be solved in a peace way? The decision of start a war that risks of triggering a nuclear war is becoming harder and harder. Also, economical benefit has become the major reason of international conflicts. All other reasons like believes, doctrines, and political systems have been weakened. When all major contries have joined a global agreement of trading ruler, I mean, WTO, and obey its regulation, all ecomonical conflicts will be able to be solved peacefully. I cannot see the risk of warfare between major countries.

Q:You talked of nothing about the threatn of global terrorism. How can you ignore their threatn while forcasting the future?
A:The question is, what's the maximum damage of terrorist attack? The most famous terrorist attack, the 911 at New York, caused hundreds of billions of dollars of lost. However, the annual global production is about 40 trillion dollars, more than 100 times of the lost. And this scale of attacking needs years of carefully preparation. Terrorism can cause social panic up to some level. However, its actual damage to the economy will always be a tiny portion. The soil of global terrorism is some most undeveloped countries. The global developing direction is to bring more and more undeveloped countries into the global economical circulation. When most persons inhabited in a region are employed, the global terrorism will no longer be able to use this region as their basement. This problem will be automatically eliminated when major terrorism cradlelands are developed.

Q:Do you think that over-light-speed traveling possible? And time machine?
A:No. Light speed is permanent boundary. One can never return to the past. These are the answer from physics theory and I have not seen any reliable new theories that can go around them.

Q:Why have we never been invaded by Aliens?
A:Since the light speed is a boundary for anybody, aliens also have to travel slower than light speed. According to this theory, it will take a tribe about a million years minimum to occupy a galaxy. This is very short comparing with the life of Milk Way, more than ten billion years. We are very lucky till now that it seems no alien has reached us or has brought up interest of occupying the solar system. We are probably the first tribe that can enter the space. Also, the astronomical observation did not find any wisdom existing evidence within 50 light years. This generally guarantees that no destructive alien will be able to reach the earth before be become a space tribe. Till now, I can only say that we are very lucky. The chance of generating life form with wisdom is very slim. Much slimer than the chance of having inhabitable planets. We may be unique, or the first one, mostly.

Q:Then what do you think of UFO?
A:They could not be alien's vessels. The size of observed UFO is not big enough for any interstellar travelling with passengers. And we have never detected any interstellar aircraft carrier. Most of them should be some kinds of natural phenomena. However, I cannot exclude the slim chance of pilotless airships from aliens. And the pilots were probably bio-bots or robots. If this were the case, the human being will be in great danger within ten thousands of years.

Q:Can we greatly enlong the life of human being?
A:I believe that we can. But this won't happen until 50 years later. The question is who will need it. The population pressure will never encourage this kind of changes until we successfully construct space resident units.

Q:Why don't you consider the chance of human being being defeated by artificial wisdom in the future?
A:I believe that the market decide the mainstream of products. In my view of future, computers made with many useless extra functions will be washed out. The remain market products are machines of obedience and machines of simple work repeaers. Who will want a machine that can make decisions for him? I highly believe that artificial wisdom will appear in the future. However, the commercial value looks low.

Q:Why don't you mention the possibility of future basic scientific discovery, which might greatly increase the power of human being?
A:I do not think that there will be one. Present technology has been enough to send us out of the earth in several thousands of years. All modern theoretical physics has reached the energy range that is too far away to be industrial used. Certainly future high biological technology will be the new source of many things, like food, cloth, etc., but this is not basic science.

Q:What's your opinion of the result of the universe?
A:The universe will run out of fuel and die - after at least hunderds of billions of years.

Q:You mentioned nothing about protecting the multiformity of life forms. What's your opinion?
A:We won't rely with them. We will be forced to eat artificial foods and use clean energy. Our demand to nature mother will start to reduce after half a century. Then their environment will automatically recover. We do not have to put in to much resource for protecting them.

Q:According to your time table, you require 16 times of global income over the global economical scale of year 2000 before human forms a big enough group in space in the year of 2500. How can you expect that the earth can stand the load?
A:Higher life cost does not always mean higher demand to natural resources. After 2050, it is expected that recycled material and regenerable power will slowly take the place and start to reduce the demand to natural resources.

Q:You predict a population peak of 11.5 billion. Where will you expect them to live?
A:In the great urban area, the population density is about 400 per square kilometers. The total area of the earth is about 140 million km2. The avarage population density is still less than 100 per km2. Meanwhile, a house for 4 persons will only take less than 600 m2. At all only less than 1.5% of surface will be used for residency. If we can produce enough food for them, I do not see any trouble.

Q:What's the expected cost of a self-standing space resident unit?
A:About 10 billion? Using this I estimated the space GDP in the year 5000.

Q:Have you got a list of situations that will make the future out of the trail you have predicted?
A:If alien attack before we occupy enough numbers of solar systems. The actural speed of developing might be slower than what I predicted.

Q:When the human being starts interstellar travelling, what's the chance of being involved in star wars?
A:About the year of 5000? I believe that we won't face a star war within 10 thousands of years.
