ABSTRACT Gravity is a well- turn in, but little understood, physical force. Its intensity and attention have been constant throughout phylogenesisary history on Earth, making it difficult to understand what role, if any, this vector force may have on life as we know it. all since the launch of Sputnick in October of 1957 has life left the planet Earth and ventured into space so that we could begin to investigate what happens to life with tokenish gravity. To date, we only have fascinating snapshots of life in space. closing of the International Space Station should allow long-duration studies over six-fold generations in multiple species. This paper explores four questions: What is gravity? What happens to life when gravity changes? Is gravity inevitable for life as we know it?
Did gravity play a role in evolution of life on Earth? Life from the cellular train through adult humans exposed to spaceflight is concisely examined and examples from spaceflight and ground-based experiments are discussed. The conclusion from these studies suggest that gravity is necessary for life as we know it, and that gravity shapes life.
