Quest for Gravity Theory: Earth's Rotation Impact?

AI Thread Summary
The discussion centers on the relationship between Earth's rotation and gravity, questioning whether rotation affects gravitational theory. It is clarified that Earth's rotation is an inertial phenomenon linked to kinetic energy, while gravity is a fundamental force arising from mass. The concept of artificial gravity through centrifugal motion is mentioned, indicating that rotation can create an illusion of gravity. Additionally, the gravity experienced on a rotating Earth differs slightly from that of a non-rotating Earth, a phenomenon known as "frame-dragging," which is being studied by Gravity Probe B. Overall, the conversation emphasizes that rotation and gravity are distinct yet interconnected concepts.

Does rotation of the earth, become a variable in the quest for the theory of gravity?
 
Physics news on Phys.org
or is there an invisible force that causes rotation to occur and gravity to exist on earth?

Rotation of the Earth has not to do with gravity, especially as we consider general gravity.

No invisible or magical force! Rotation occurs as an inertial phenomenon (kinetic energy), while gravity is a fundamental force that results from its mass.
 
yeah gravity is a by product of mass, the more massive the object, the more gravity. now if you are talking about rotation and the creation of artificial gravity, then that's just the centrifugal motion created by the spin pushes anything towards the edges thus creating an illusion of gravity
 
I'm not sure I understand the question, but the gravity of the rotating Earth is ever so slightly different than the gravity it would have if it were non-rotating. This "frame-dragging" effect is currently being confirmed by Gravity probe B.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
