Well every theory does have its "flaws" and need a bunch of facts and mathmatics to try and "prove" them. This can go for lots of things, but they may not use mathmatics to describe how they work. Gravity does have its flaws but for the most part its what we use to describe the earths pull on things and is widly accepted. For the most part I agree with gravity, but ill leave the flaws to be worried about by people who work with these theories in their everyday lives.
well if gravity is only a theory it is one which has very strong evidence to back it up, and it has not been disporved since the theory was established which was a very long time ago, leading to many people believing it, as well as it not being disproved there is also alot of evidence to back it up so i would say that gravity is not just a theory but is acually true
How can physics who spend 8 years in school(after high school) to get a PhD be wrong? The theory of gravity is a theory so therefore if your asking if its a fact, then no. But there is no better explanation. The author seems to bring in many points that could be rebutted by a physicist. You are only seeing his point of view when reading this article. I suggest taking a physics course in high shcool before one can even speculate their opinion on gravity.
