If the mankind lives the world goes suddenly with the sun giant, but population amount is fixed, wha

The individual thinks, if the world becomes great like the sun, other condition is changeless, so right earthly shadow is answered main from aerospace environment and oneself condition two respects are mirrorred, generally speaking, celestial or heavenly body is larger, gravitational force is larger, can attract more celestial bodies, so its universe environment can become not so safe, oneself bulk greatens, to the person that tellurian lives, that is the ground undoubtedly wide person is rare, natural resources is very sufficient.

To present earth, everybody is very familiar, for the position from inside the universe, earthly position is advantaged, so also be pregnant with now tellurian life, and the condition that is in stability for a long time, this is as located as its also the environment is having tremendous correlation, it is after all in solar system, the sun is the biggest star, and very stable, it is light of the person that the earth is offerred and heat continuously, and the distance of the sun and earth is proper, let there is an appropriate temperature environment on the earth, and the mainest is bulk size of the earth also have an advantage very much, can say not to calculate big, but it is very good bulk size however, and the distance does not have the Jupiter with huge volume to keep out wind and rain for its too far, after all the Jupiter with huge volume is beside the earth, can attract as a result of powerful gravitational force bear down on originally a few asteroid of the earth, assured earthly safety on certain level thereby, look on one hand from this, jupiter resembles a very strong big elder brother, always protecting puny earth, avoid the harm that suffers ab extra asteroid.

If take no account of cosmic environment, the earth becomes and the sun is euqally giant, so tellurian illumination origin also is a problem, original after all sun is bigger than the earth too much, be equal to is headlight beamed zonule, and now is as identical as earthly volume size etc come illuminate earth, because bulk increases,can make on one hand both distance becomes close, a side temperature that brings about adjacent of as open as the day look is too high, and if rotation rate is fixed, so big surface is accumulated, the word of rotation circuit, criterion speed needs to just go very quickly, from on the other hand for, if these are not problems completely, mix original earth is similar, so the mainest is the earth expresses an area to greaten, ground wide person's rare appearance is very serious.

Although the land is extensive the person is so rare, but may form more the earth of rich and colorful, vast after all space is the element of a condition that biology diversity develops, to our mankind, more places are desolate and uninhabited perhaps, but resource is enough for certain, of course, these is to guess, everybody can express an opinion at will, hope to communicate together with everybody!
