Foundational considerations in definition of Newtonian Spacetime
My doubt comes from lecture 08 on Theoritische Mechanik by Frederic Schuller.
He gives definition of Newtonian Space time as followg:
A Newtonian Spacetime is a quintuple of structures $(M,\mathcal{O}...

Newtonian gravity as curvature of space
Since Newtonian gravity is also indistinguishable from acceleration, it should be possible to formulate it as a curvature in space, right? For example, if a body changes velocities purely under the ...

Why isn't general relativity equivalent to Newtonian gravity?
I know this question may seem a bit laughable, but the way the equations for general relativity are formed is through Poisons equation:
$$\nabla^2\phi=4 \pi G \rho$$
Which are formed using Newton's ...

Contravariant metric in Newton-Cartan spacetime
I'm interested in the geometrized Newtonian gravitation or Newton-Cartan theory. In every reference that I have found begins saying that a Newton-Cartan spacetime is a manifold $M$ with some ...
