Scientific investigations into the truth
Everyone must understand the universe and the nature of the individual souls living in it. Those who recognize the secrets of the Cosmos and of the beings living in it can understand the nature of Divinity. Since ancient times, men of wisdom have investigated into Nature. The astronomer Galileo discovered many facts about the universe. The Earth revolves at a speed of 18,500 miles per second. It circles the Sun once a year. "Who is turning the Earth? Why does it revolve? What is the basis for its revolution?" asked Galileo. He found that the parabola is the basis of motion.
