Elena Giorgi is an assistant professor of mathematics at Columbia University in the group of Geometry & Analysis and Mathematical Physics. Giorgi's research interests are general relativity, partial differential equations and differential geometry. What is general relativity? General relativity is a physic...
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 ...

While general relativity is more accurate in explaining gravity than Newton's Laws, the difference in calculations using either is noticeable for the most part only on "relativistic" scales – looking at extremely massive objects in the cosmos, or a near-light speeds. Therefore Newton's Laws rem...

various kinds of theories in physics. Most of them are constructive. Theyattempt to build up a picture of the more complex phenomena out of the materials of a relativelysimple formal scheme from which they start out. Thus the kinetic theory of gases seeks to reducemechanical, thermal, and ...
From the hoverboards of "Back to the Future" to the gravity guns of "Half-Life 2," science fiction is peppered with antigravity technology. In the real world of peer-reviewed studies, corporate-funded labs and general relativity, however, "antigravity" is a dirty word. Gravity, you undoubted...
Albert Einstein, who won the Nobel Prize in Physics in 1921, contributed an alternate theory of gravity in the early 1900s. It was part of his famous General Theory of Relativity, and it offered a very different explanation from Newton's Law of Universal Gravitation. Einstein didn't believe...
What is relativity? Succinctly put, it is the notion that thelaws of physicsare the same everywhere. We here on Earth obey the same laws of light and gravity as someone in a far off corner of the universe. [8 Ways You Can See Einstein's Theory of Relativity in Real Life] ...
