What is gravity? Intro Draft

You certainly do not have to be a physicist to know of gravity. Gravity is not some obscure concept mentioned only in the lingo of die-hard astronomy fans, like a quasar or a red giant. Gravity is a concept known by toddlers and astrophysicists alike. From a young age, we learn that when we throw a ball up, it must come back down. We learn that if we slip on the money bars, gravity will bring us hurtling toward the ground. And sadly, we learn that we cannot fly. These lessons are all thanks to gravity. And it doesn’t stop there. We all feel gravity constantly, pulling us to the ground when we are sitting, standing, running, skipping, and jumping. John Mayer even wrote a song about it. We all know of gravity’s existence just like we all know the sky is blue. But while anyone and everyone can recognize that gravity exists, not many people have probably sat down and really asked themselves, from what source does gravity originate? What really IS gravity? And that is where physicists come into play, and the answer is not quite as simple as the concept itself.
