Ghhhhhhhhhhhhhhhhhj, In the beginning it was dark and cold. There was no sun, no light, no earth, no solar system. There was nothing, just the empty void of space. Then slowly, about 4.5 billion years ago, a swirling nebula, - a huge cloud of gas and dust was formed. Eventually this cloud contracted and grew into a central molten mass that became our sun. At first the sun was a molten glow. As the core pressure increased, and the temperature rose to millions of degrees - a star was born. Through the process of thermonuclear hydrogen fusion, the sun began to shine.
This was the nebular hypothesis, first proposed in 1755 by the great German philosopher, Immanuel Kant.

THE SUN - (c 4 Billion BC)
Our sun is an atomic furnace that turns mass into energy. Every second it converts over 657 million tons of hydrogen into 653 tons of helium. The missing 4 million tons of mass are discharged into space as energy. The earth receives only about one two-billionths of this. Scientists calculate that the sun should keep burning for another 10 to 30 billion years. It has been estimated that in 15 minutes our sun radiates as much energy as mankind consumes in all forms, during an entire year.
The sun is approximately 93,000,000 miles from the earth, 864,000 miles in diameter, and is only an 'average' star in size, brilliance and age. There are more than 100 billion other stars in our sun's own galaxy, the Milky Way. Energy, with a color temperature of approximately 6500 degrees Kelvin, is received on earth, from the sun. It takes light from the sun approximately 8 minutes to reach the earth. The illumination on the earth's surface by the sun may exceed 100,000 lux, (10,000 fc) in mid summer.

THE EARTH - (c 4 Billion BC)
About 4 billion years ago, soon after the Sun was formed, the Earth and our other planets were formed from violent explosions and spinoffs from the process
