First, gravity is a force that causes objects to attract one another. The simplest way to understand gravity is through Isaac Newton's law of universal gravitation. This law states that every particle in the universe attracts every other particle. The more massive an object is, the more strongly it attracts other objects. The closer objects are, the more strongly they attract each other. An enormous object, like the Earth, easily attracts objects that are close to it, like apples hanging from trees. Scientists haven't decided exactly what causes this attraction, but they believe it exists everywhere in the universe. Second, air is a fluid that behaves essentially the same way liquids do. Like liquids, air is made of microscopic particles that move in relation to one another. Air also moves like water does -- in fact, some aerodynamic tests take place underwater instead of in the air. The particles in gasses, like the ones that make up air, are simply farther apart and move faster than the particles in liquids.|Does a change in temperature create the perfect recipe for cold and flu? Raise your hand if a parent, grandparent or an older, wiser, caretaker of any kind has scolded you for not bundling up when temperatures drop. If you're waving your arm frantically, you're far from alone. Across cultures and geographical boundaries, there seems to be a long-held, pervasive belief that sudden meteorological changes automatically trigger colds and flus. But does the theory really pan out? According to health experts, weather-driven sickness is a thing, but the temperature itself is more of an indirect cause of the resulting illness. In other words, it's not the cold temp itself that makes you sick, but the environmental factors related to it. What does likely set you up for sickness is the drop in humidity associated with that sudden drop in temp. As pulmonologist Ray Casciari told The Atlantic, in a low-humidity environment, "your eyes tend to dry out, the mucous membranes in your nose dry out, and your lungs dry out, and you're therefore much more susceptible to bacteria and viruses." And because viruses are more likely to survive and replicate in cold than heat, you're more likely to get sick when the weather turns frigid.
