GRAVITY
Gravity is a very important force in the Universe. Every object has gravitational pull which is like magnetism. But unlike magnetism, gravity is not only in iron and steel. Isaac Newton, a great scientist of the 17th century, studied gravity first.
According to the law which he produced everything in the universe attracts everything towards itself. The Sun attracts the Earth and the Earth attracts the Sun. All objects have some attraction but we do not notice the gravitational pull of a book because the pull of the earth is much greater.
Why does the Earth always move around the Sun and not fly off into cold space? The Suns gravity gives the answer. The Earth always tries to move away in a straight line, but the Sun always pulls it back. So it continues on its journey around the Sun.
The sun is one of the stars in the galaxy, in which there are about 100 000 million stars. It is not in the middle of the galaxy, but near the edge. These stars form a group in the shape of a watch.
There are millions of galaxies in the universe and so there are thousands of millions of suns. Many astronomers believe that some of them have planets as our sun does.
Gravity is a force which holds all the atoms of a star together. It holds the Sun together and it holds the atoms of the Earth together. It holds us on the Earth.
Einstein developed a new law of gravity. Its main results are the same as the results of Newtons law but in very small and fine matters Einsteins law gives different results. One of these is that gravity bends light a little but according to Newtons law gravity has a very little effect on light. Einstein showed this fact by means of mathematics and not by experiment and astronomers later proved by experiment that Einstein was right.
