Crystal

In countless bright stars, except for planets, most are self-luminous, and are relatively stable. Those are the essentials. They are lights that are not turned off in the morning and eternity. The sun is the closest one to us. The crystals are far away, the close neighbor star is also 4 light years away. If we pull that neighbor close like the Sun, we will have one more Sun.

The ancients believed that the relative position of the crystal was constant. In fact, not only does the planet spin itself, but it also travels in the universe at different speeds, faster than the speed of spacecraft, only that they are too far away so people don't realize it.

All crystals are extremely large bodies. For example, the Sun's diameter is about 1.4 million km; 109 times the Earth, 1.3 million times the volume of Earth. In the vast cosmic ocean, the Sun is just a very ordinary member. Giants in the planetary world have tens to hundreds of times the diameter of the Sun. Their mass is 0.5-5 times more massive than the Sun, a few crystals have tens of times the Sun's mass.

The intensity of the light is not the same, even if it is the same, but the distance to us is far different, so the brightness is also different. People base on visual brightness, divided into 6 levels. That is the star level of astronomy. The brightest star is called level I star, followed by the star level II, level III, level IV, level V, the star is dark but the naked eye is still visible at level VI. After having a telescope, people saw more dark stars than Tier VI stars. There is another level called "absolute level". Absolute levels reflect the brightness or the total amount of glow of the planet itself, meaning different from the star level.

The gaseous body is mainly hydrogen, followed by helium. In a temperature of 7 million degrees Celsius, four nuclei of hydrogen atoms combine to form helium atom nuclei, while emitting a huge amount of energy. That is the fusion reaction. The hydrogen bomb (hydrogen) has a strong explosion, thanks to this fusion reaction. Internally, there are always "hydrogen bombs" that are "exploding", making crystallization a large fireball with a hot gas body, emitting light and heat. The temperature of the crystalline phase decreases from the center to the edge. But the surface temperature of the crystalline is still great: the lowest is also more than 2000 ^o C, sometimes high up to 40,000 ^o C. The temperature of the Sun is 6000 ^o C. The surface temperature of the crystal determines its color. This is like a burning iron ingot, the temperature rises and it changes color from red to yellow, white, even blue.

Refinement is the most basic members in the universe. For each planet, they also have a date of birth and death. But this series of starches died, and a new series of crystals was born. Therefore, the universe always exists countless "Sun".
