How did Surplus lead to civilization?

As time passed, early farmers continued to develop new methods to increase farm production. As a result, farmers could plant more crops and produce more food. With irrigation, some farmers began to produce a surplus, or excess, of food. With surplus food, villages could support larger populations.

What is a surplus and why was it so important for the development of civilizations?

The earliest civilizations developed between 4000 and 3000 BCE, when the rise of agriculture and trade allowed people to have surplus food and economic stability. Many people no longer had to practice farming, allowing a diverse array of professions and interests to flourish in a relatively confined area.

What is an ideal civilization?

The ideal civilization, whether it’s on an alien planet, or here on Earth, will consist of an egalitarianistic society, a system of law and order that focuses on rehabilitation instead of punishment, and a hybrid system of government. In the ideal civilization, conflict must be kept to a minimum.

What is the purpose of a Dyson sphere?

A Dyson sphere is a hypothesized artificial habitat built around a star by a civilization with sufficient technology. It is intended to capture as much as possible of the power output of the star, and should be a distinctive characteristic of a civilization able to control the resources of a planetary system.

Who came up with a Dyson sphere?

Freeman J. Dyson

How long would it take to build a Dyson sphere?

That’s about 120 trillion years. Of course, that’s only the first stage. Going simply by the numbers that Dvorsky provides, without critique or comment, the Dyson sphere would eventually encompass 6.9 x 10^13 square kilometers.

When was the Dyson sphere invented?

1960

Is a ring world possible?

To get Earth-like gravity, the Ringworld would need to spin at nearly three million miles per hour. Very fast, to be sure. But in a frictionless space environment, it could be doable.

What if we build a Ringworld in space?

A ringworld would also need to maintain some form of gravity; otherwise everything, including the atmosphere which it would need to keep its inhabitants alive, would float off into deep space. The most common way to create artificial gravity is through the generation of centrifugal force through rotation.

How old is Larry Niven?
