Why Are Dark Matter And Modified Gravity In Such Conflict?
The laws of gravity are some of the most well-established and best-tested physical laws of all-time. If you made an observation of a massive object in space - a planet, star, galaxy or something even bigger - that didn’t appear to line up with what gravitation predicted, you’d be crazy not to double-and-triple-check what you saw. But every once in a while, either our laws of physics or our understanding of what’s in the Universe turn out to be incomplete, and it’s up to us to figure out the way forward. Right now, a huge academic battle is taking place between two camps seeking to fix the gravitational problems of the Universe: the dark matter camp and the modified gravity camp. This is a battle
