Out Of Environment Space

Please correct me if I'm wrong, but if people talk of "empty space" is that the reference to the absence of matter in space? (N molecules of gas, etc.) I'm so confused, BC All this time I imagined a vacuum is created in a black hole ..? And just thought served as a vacuum suction environment ... lol (like what the cleaner does!)

And I'm curious to know what a space suit protects astronauts from space. I know there is no oxygen there so that you can die of anoxia, but then there are ideas people explode because the sudden change in pressure? I do not know how it goes, and I read other peoples questions and people say you would not blow up the British Columbia skin is elastic but they say things all the liquids will boil? .. I do not understand, why? What is the space environment as ... Is it totally devoid of gas? .. How, why? The planets have gas escaping into space ...

Also, what is the pressure in space?

Please explain in simple terms .. super Learn to talk to a sixth grader. I'm really ignorant on this subject, lol.

I think space suits provide more protection. They provide oxygen and temperature of your body to survive. space itself is not so different from the earth except that there is no breathable oxygen temperatures, nor sufficient. I do not think the pressure is too different either.

gravity and the lack of gas are not the same thing

the gravity of the black hole =
lack of space = gas, or "air"

the combination is pressurized with O2 and other gases

a true vacuum, it is something completely devoid of mass and energy. space is almost empty, but there are still suspended particles around there. As to "explode" it would not happen. The pressure difference is not large (not large enough to cause an explosive decompression), but it may boil the blood and other liquid in your body. The temperature in space is a sensitive issue. The temperature is the kinetic energy of atomic particles, in space there is none, so technically it is absolutely 0, but if you introduce something that has a temperature in space would not immediately freeze because there are no other particles around the "lock" the energy away. However, it would radiate heat until it freezes. "
