- Your new theory must reproduce all the successes of the leading theory. So, you’ve got a new theory that you hope will supplant the presently leading one?
- Your new theory must succeed where the prior theory does not. It’s true that theorists play in the sandbox all the time: even if our current explanation is 100% satisfactory, we’re always looking for new solutions to old problems.
- Your new theory must make new, testable predictions that differ from those of the original theory. Each one of these ideas for a new theory of gravity or massive phenomenon in the inner Solar System would have observable consequences: consequences that would distinguish them from not only one another, but from the prevailing, older theory of Newtonian gravity.

- What to Expect When Learning General Relativity on Your Own
First of all, it’s important to know what you’re in for when beginning to study general relativity (and special as well, but it’s much much easier). In particular, the typical prerequisites for general relativityare: 1. A basic understanding of special relativity 2. Electromagnetism (optional, but helpful) 3. Newtonian mechanics (optional, but help...
Now, I’m definitely not a professional physicist, so I can’t teach you how to become one either. What I can help you with are the steps in learning the most important concepts of relativity on your own, because that’s exactly what I’ve done myself. The steps given below are either what I’ve done myself that have personally been beneficial to me or ...
Now that we’ve gone through the necessary steps to learning general relativity, there may still be some questions you’re wondering, such as“how difficult will learning general relativity be?” or “how long will it take to learn these things?”. This is what I’ll answer next. Keep in mind that these are based on my experience after actually self-study...
As a brief introduction, general relativity is the most accurate theory of gravity so far, introduced by Albert Einstein in the early 1900s. General relativity explains gravity as a property of spacetime rather than a force, namely, as the curvature of spacetime, which is caused by matter and energy.

For 100 years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don’t need superpowers to understand it. Begin with Isaac Newton’s first law of motion: An object remains in uniform motion unless acted on by a force.
General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
Einstein’s Theory of General Relativity is a theory developed by Einstein in order to describe gravity in a way that is consistent with Special Relativity and the propagation of light.
Confirmed by Arthur Eddington (1882–1944) England in 1919. General relativity replaces Newton's theory of universal gravitation as the most complete theory of gravitation. Newton and Eddington were English. Einstein was German. 1919 was the first year after World War I. Anti-German sentiment was still high in Europe.
