Oh, the previous comment I just read asked if Dr. Witten was overrated? My response is, are you fucking kidding me? Who are you, God? This man is brilliant, and I’ve never even heard anyone come close to being able to match his level of insight and intelligence in his field. To question his competence is absurd and ridiculous and rather pathetic to be truthful. Peace.
Einstein wrote down what he could prove actually exists. There are still multiple theories that branch from relativity. This is an in depth description of some of those potential possibilities. They are rules that encompass around mass and spacetime. It also answers a lot of questions using theory of relativity based on momentum, spin, position.. Why he explained it was trivial, however less trivial than it not being so, is because overall it makes mathematical sense for M = 0 than for more than 0 to exist for some other reason. It violates 2 laws he describes, but with reason and explanation. Although the initial figure will always be a silhouette. Without Einstein's equations, we would hardly have any of these in-depth answers today. Its vital to the theory
