Exploring General Relativity: Frame-Dragging and Mach's Principle

  • Thread starter Povel
  • Start date
In summary, General Relativity is a theory that describes the relationship between gravity and the curvature of space-time. One of its key concepts is frame-dragging, which suggests that rotating massive objects, such as planets or stars, can "drag" the space-time around them. This effect was confirmed by the Gravity Probe B experiment in 2011. Another important concept in General Relativity is Mach's Principle, which states that the inertia of an object is influenced by the distribution of matter in the universe. While it is still a debated topic, Mach's Principle offers a potential explanation for why objects in space appear to follow the same laws of motion. Overall, these ideas play a crucial role in our understanding of gravity and the behavior of objects

I'm an aerospace engineer currently working in a different field.

I've been interested in fundamental physics since quite a while.
My background doesn't allow me to follow discussions over these subjects in detail, but generally I can follow the core concepts behind the passages.Currently, when I have some spare time I like to read about General Relativity, in particular about frame-dragging and its connection with Mach's principle. I have several questions about this and other subjects I hope I'll be able to satisfy thanks to this community :)

Hello and :welcome:!

You might also want to inspect our insights blog where many essays about various subjects can be found! We currently have more than 500 articles, and quite a few are about general relativity, black hole metrics etc.
