Ever jumped from a diving board? Had a thrilling ride on a roller coaster? Then you have had the experience of many astronauts in space. You have experienced microgravity! What is microgravity? It is zero gravity, weightlessness, or the feeling of falling without the presence of gravity. Scientists are dedicating lots of research to microgravity because we may be able to develop materials that cannot be made here on earth due to gravity, but that can be beneficial to our way of life. These new materials can be used to speed up future computers, reduce pollution, improve fiber optics, and enable medical breakthroughs to cure diseases.
