Quoted directly from The Universe in a Nutshell by Stephen Hawking
Time and space are defined by measurements within the universe, such as the number of vibrations of a quartz crystal in a clock or the length of a ruler.

Now a few theorists predicted that time and space intermingled at some points, which led Einstein to show how time slows down with speed (the experiments with the Atomic Clocks in the aeroplanes).

Quote continued from The Universe in a Nutshell by Stephen Hawking
It is quite conceivable that time defined in this way, within the universe, should have a minimum or maximum value--in other words, a beginning or an end. It would make no sense to ask what happened before the beginning or after the end, because such times would not be defined.
It was clearly important to decide whether the mathematical model of general relativity predicted that the universe, and time itself, should have a beginning or end.
