Despite the fact that we are unable to feel it, air is continually pressing down on us with great intensity.
Despite the fact that we are unable to feel it, air is continually pressing down on us with great intensity. Although this force is invisible to the human eye, its effects are constantly felt, particularly when driving up steep slopes or stepping off an aeroplane. There is a continual equilibrium between the external pressure from the air and the inside pressure from our heartbeat. In space, there is no air, as we just discussed. As a result, there is no air pressure in outer space. As a result, to exert the required external pressure on the astronaut, Spacesuit are filled with a specific volume of air and inflated similarly to a balloon. As a result, during a spacewalk, astronauts' bodily fluids can continue to be liquid.
