Combining Newtonian Gravity and length contraction from SRT?

The value of $\gamma$ that I will use is $$\gamma=\sqrt{1-\frac{v^2}{c^2}}$$ And length contraction is $$L_0=\frac{L}{\gamma}$$ Where all variables have usual meaning. Let the gravitational pull on ...

Can we construct a logically self-consistent relativistic theory of gravity just by tweaking EM?

This question considers a modification of classical E&M where we simply reverse the relative sign in Maxwell's equations and change the "$q$" in the Lorentz force law to an "$m$&...

Numerical solution to the relative gravitational time dilation of induced dipolar gravitational fields

In gravitoelectromagnetism, an approximation to general relativity in the weak field limit, Einstein's equations simplify into a form very similar to Maxwell's equations. In this field, traditional ...

Are there good reasons why special relativity should motivate geometrised gravity in a way that Newtonian mechanics does not?

I have studied a bit of Newton Cartan theory recently, the geometrised version of Newtonian gravity in which gravity is due to the curvature of spacetime, but is Newtonian (simultaneity is absolute). ...

Why can't we insert gravity in the special relativistic lagrangian?

I am a math student and I have taken four-five lessons about special relativity in a course about Lagrangian and Hamiltonian mechanics, so be patient with me if my question is stupid. My teacher says ...

Maxwell-like equations from Newton's law of universal gravitation and special relativity

It is known that Maxwell's equations can be derived from Coulomb's Law and Special Relativity. Since Coulomb's Law is so similar to Newton's law of universal gravitation, is it also possible to derive ...

Newton's gravity vs Einstein's gravity

Hello so if i were to simplify the difference between gravity as seen from Newton and gravity as seen from Einstein, could i say that Einstein's gravity is just adding the fact that gravity does not ...

How does Newtonian gravitation conflict with special relativity?

In the Wikipedia article Classical Field Theory (Gravitation), it says After Newtonian gravitation was found to be inconsistent with special relativity, . . . I don't see how Newtonian gravitation ...
