What is general relativity? General relativity is a physical theory about space and time and it has a beautiful mathematical description. According to general relativity, the spacetime is a 4-dimensional object that has to obey an equation, called the Einstein equation, which explains how the matt...
A. General relativity is actually ungrounded at all. B. The calculation of the orbits shows that equivalence principle is violated. C. More should be done to prove the correctness of equivalence principle. D. A new revolution in physics has already arrived. ...
Even within the framework of geodesic completeness there is still a great variety of definitions to choose from. It is claimed that none of these definitions is entirely satisfactory. 关键词: n34430* --physics (theoretical)--gravitation & general relativity general relativity theory gravitation ...
This paper proposes therefore a definition of finite-perimeter sets and their reduced boundary in general relativity. Moreover, a basic integral formula of geometric measure theory is evaluated explicitly in the relevant case of Euclidean Schwarzschild geometry, for the first time in the literature. ...
The goal of this article is to make everyone understandrelativity. In fact, relativity is not as complicated as you think. Why do many people find relativity extremely complicated? That's because general literature makes simple issues overly complex. You will definitely be able to understand it....

Einstein's theory is divided into special and general relativity. Special relativity came first and is based on thespeed of lightbeing constant for everyone. That may seem simple enough, but it has far-reaching consequences. Einstein came to this conclusion in 1905 after experimental evidence showe...
Science, I lectured sternly, has established many facts about reality beyond a reasonable doubt, embodied by quantum mechanics, general relativity, the theory of evolution, the genetic code. This knowledge has yielded applications—from vaccines to computer chips—that have transformed our world in ...
These are just a few of the questions author and astrophysicist Jeffrey Bennett answers in his new book, "What is Relativity" (Columbia University Press, 2014). On the 100th anniversary of Albert Einstein's general theory of relativity, Bennett's book seeks to explain both special and general...
What is called atomic energy is actually nuclear energy.所谓的原子能就是核能。 The result is what is called Anglo-Saxon or Old English.结果是所谓的盎格鲁-撒克逊语或是古代英语。 Einstein's general theory of relativity is what is called a classical theory.爱因斯坦的相对论被称为一种经典理论。
