Why do space suits have to be pressurized to three atmospheres?

Perhaps for testing purposes, to check for leaks. There would be no reason to do it with an astronaut inside, in fact it would be very dangerous. A blowout would give the astronaut the "bends" and quite possibly kill him. If I remember correctly, in space they run about 1/3 to 1/4 of sea level pressure, of pure oxygen, in order to keep the suits limber enough to move around in. Too much pressure inside and the suit would "starfish", splaying out and leaving the astronaut nearly immobile. The first spacewalker was a Russian, who had to release a lot of his air pressure in a hurry so he could get back inside his craft!

Why do divers watches say they are pressurized to three atmospheres?
This basically means that when the diver is underneath the water, the pressure down there is 3 times the pressure at normal land level. This means that the watch won't crack or break at three atmospheres worth of pressure.

How does science define the term 'space'?
Space is the three-dimensional gravitational field in which all matter and energy exist and interact. It is measured in length, area, and volume. In astronomical and common parlance, the term refers to the near-empty region outside the earth's atmosphere as well as the atmospheres of all other bodies in the universe. It is the property of the universe in which material entities coexist with each other and have extension.
