BizSugar.com › Marketing › Seth's Blog: Gravity is just a theory

Everyone 'believes' in gravity. And yet, we know virtually nothing about it. We don't know how gravity waves (if there are any) are transmitted. We can't block them (anti gravity boots!) and we can't amplify them and we have no idea how fast they travel. There are very few people doing serious gravity research and development, either. But it's apparently a law.
