TL;DR Summary
On-Line class suggestions
Can anyone recommend a good on-line class for differential geometry? I'd like to start studying GR but want a good background in differential geometry before doing so. Many thanks.

Maybe @jedishrfu has some idea because he normally has a good overview of online video sources.
 
This topic is much harder to find courses on as I’ve tried in the past. However, I did find the MIT Open Courseware course:

https://ocw.mit.edu/courses/mathematics/18-950-differential-geometry-fall-2008/

or this course by Prof Arezzo which looks pretty thorough:

and some more visual ones on YouTube which I like because of the relative shortness of the videos and the use of interactive graphics:



My differential Geometry knowledge is somewhat dated with many cobwebs. I learned pieces from an independent studies in General Relativity and in math using Wheeler‘s Gravitation and McConnell’s Dover book on the subject. More recently I looked at Flanders book on Differential Forms but had no time to really get into it.

Personally, I would check out the last selection by Faculty of Khan and then slog through the larger format Prof Arezzo for greater understanding and lastly the MIT one to complete your understanding. I believe they are all at the undergrad level so I guess after that one would tackle the relevant books like Wheelers and Flanders.
 
Many thanks for all the info.
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As the object becomes heavier, the speed of matter falling on it for an observer on Earth will first increase, and then slow down, due to the effect of time dilation. And then it will stop altogether. As a result, we will not get a black hole, since the critical mass will not be reached. Although the object will continue to attract matter, it will not be a...
