Space and space are the same. So there is no difference between them. The sky rich in the atmosphere of the earth is the sky of the earth. And the eternal space outside this sky is space or space. Space began about 100 km above the Earth's surface just outside the Carmen Line. Although it seems empty to the naked eye, space is not completely empty. Mainly , very small amounts of hydrogen plasma , electromagnetic radiation , magnetic fields and neutrinos are located there. However, there is no air pressure in space. That is why the plane cannot move , the rocket can move. Because the air has to use air to fly. So long-distance travel in space is still extremely dangerous. Space is still extremely dangerous for humans. Although space or space is generally referred to as the eternal sky above the head, in fact, the atmosphere of the earth's atmosphere is called the sky of the earth. So in the context of the Earth, space is the eternal space outside the Earth's atmosphere. Objects of very small density exist in this airspace. That is, the empty space is not completely empty. Mainly , very small amounts of hydrogen plasma , electromagnetic radiation , magnetic fields and neutrinos are located in this vacuum. Theoretically , it contains black matter and black energy. There are so many things in space that people still can't imagine. There is no gravity in space , no air , no atmosphere. So there is no way for all living things in space to resist the extremely high levels of radioactive rays that are blocked by the Earth's magnetic field . The temperature there is very hot at +120 degrees Celsius. More than that , not too cold -120 degrees Celsius. Or even lower! People do not have the ability to deal with such an extreme environment! Interestingly , those spaces 100 km above the earth but no special country or nation. Everyone has equal rights there.
