Lectures on Advanced General Relativity

http://sites.google.com/site/winitzki/

contains [among other things] is a set of free lecture notes on advanced stuff like index-free calculations with vectors and tensors, differential forms, null surfaces, asymptotic flatness, singularity theorems, tetrad formalism, and spinors in GR. This is a free book in the sense of http://www.gnu.org/copyleft/fdl.html" .

Dx, your link is to an empty page - fancy writing it ?

The website
Relativity on the World Wide Web
by Chris Hillman

contains a large collection of links to relativity websites and lecture notes
on the level of introductory as well as advanced.

Sadly, this page has since been withdrawn:

"RelWWW has existed for approximately 15 years, but in the past 5 years it has become clear that I lack the time and inclination to properly maintain this website. More seriously, the World Wide Web has not developed in the way I hopefully anticipated back in 1992. Consequently, I have concluded that the site is no longer useful for the hypothetical "serious student" whom I envisioned as the target audience. Therefore, I have deleted it.

- Chris Hillman, June 2007"

This particular link no longer works, BUT it shuttles you to his main page, where he now has extensive links to material on many topics (scroll down to bottom third of page):

1. What is the theory of General Relativity?

The theory of General Relativity is a cornerstone of modern physics that was developed by Albert Einstein in the early 20th century. It is a mathematical framework that describes the behavior of gravity and the structure of spacetime.

2. How is General Relativity different from Newton's theory of gravity?

Newton's theory of gravity, also known as classical mechanics, describes gravity as a force between masses. General Relativity, on the other hand, explains gravity as the curvature of spacetime caused by the presence of mass and energy.

3. What are some key concepts in General Relativity?

Some key concepts in General Relativity include spacetime, gravity as curvature, the equivalence principle, and the geodesic equation. These concepts help us to understand the behavior of objects in the presence of massive bodies and the structure of the universe.

4. How has General Relativity been confirmed?

General Relativity has been confirmed through various observational and experimental tests, such as the precession of Mercury's orbit, the bending of light around massive objects, and the detection of gravitational waves. All of these tests have provided evidence that supports the predictions of General Relativity.

5. What are some applications of General Relativity?

General Relativity has several practical applications, including GPS technology, which requires correcting for the effects of gravity on time dilation. It also plays a crucial role in astrophysics, helping us to understand the behavior of objects like black holes and the expansion of the universe.
