|If you were out in space and could see every individual person clearly, would it look like they were walking at a slant? — KD, McMinnville, OR
To the astronauts orbiting the earth, up and down have very little meaning. Because they are falling all the time, these astronauts have no feeling of weight and can't tell up from down without looking. If an astronaut were to look at a person walking on the ground below, that person might easily appear at a strange angle, depending on the astronaut's orientation and point of view.
