The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.

example: The Sun is the star at the center of the Solar System.

For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.

example: when you thrown an apple in the air and it falls back down that's gravity.

This produces a visible atmosphere or coma, and sometimes also a tail.
