    Force Gravity
AI Thread Summary
Gravity is traditionally viewed as a force in Newtonian physics, where it acts at a distance between masses. In contrast, Einstein's theory of relativity redefines gravity as the curvature of spacetime caused by mass, eliminating the notion of gravity as a force. This fundamental difference highlights that while Newton's model is effective for many practical applications, Einstein's perspective provides a deeper understanding of gravitational phenomena. Despite advancements in physics, the true nature of gravity remains elusive, with ongoing debates about its fundamental properties. Ultimately, both theories offer valuable insights, yet they approach gravity from distinctly different frameworks.

Is Gravity a force??What is basic difference between Einstein and Newton's view on Gravity??

No one knows what gravity is. And in general, no one knows what nature really is.

Gravity is modeled to be a force in classical mechanics. In relativity, gravity is not a force.
 
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
