The sun, at the center of the solar system, is just one of about 100 billion stars in our galaxy, or collection of stars, called the Milky Way. 2_______ have estimated that there are about 100 billion other galaxies in the universe. Most scientists 3_______that the universe formed about 15 billion years ago in an enormous explosion called the big bang. They also think that 4_______ is expanding.

There are billions of stars in the universe. Stars are massive, energy-filled globes of fiery gases. The force of gravity holds these gases together. At a star’s core, atoms of hydrogen join together to form helium in a process called nuclear fusion. The energy generated by this process produces a star’s heat and light. Collections of stars are called galaxies, and each galaxy contains many different types of stars.

The work of Italian scientist Galileo Galilei revolutionized astronomy. Galileo developed the telescope and made important discoveries about the planets and the sun. His observations confirmed the work of the Polish astronomer Nicolaus Copernicus who believed that the Earth and other planets revolve around the sun. This finding went against the Church’s teaching that the Earth is the center of the universe, and the Church punished Galileo. Galileo suggested the use of the pendulum in clocks and also discovered an important principle about gravity.

Organic chemistry is the study of compounds containing carbon. It is called “organic” because scientists used to think that these compounds were found only in living things or fossils. However, vast numbers of different carbon-containing compounds can now be produced artificially in laboratories and factories, for use in industry. For example, drugs, plastics, and pesticides are all synthetic organic substances. About 4.5 million of the 5 million compounds known today contain carbon.

We determine how hot or cold something is by a measure called temperature. This tells how much energy the atoms (tiny particles) inside a body contain. The more energy the atoms contain, the faster they move, and the higher the temperature. For each element (simple type of substance), there are specific temperatures at which changes of state occur. These are known as melting and freezing points. Scientists believe that absolute zero is the lowest possible temperature, below which atoms would have no energy.
