What is gravity? How does it work, and how did we figure it out? 
This video explores how gravitational theory developed over time, and its significance not only as a fundamental force, but as a key concept in unifying our understanding of the laws of physics and the universe as we know it.

This video was a passion project of mine, created to introduce younger students and underclassmen to physics and astronomy. I've always been fascinated by gravity, and all the effects it has on both our universe, and everyday lives. I wanted to share a little of what I've learned throughout my studies and research, and sought to create a holistic view of how our understanding of gravity has developed across human history.

Please feel free to share and use for instruction, or just leave a like and comment below what you think! This is my first ever project in motion design, but I would love some constructive feedback!
