How do we interpret measurements of Mercury's position?
When scientists measured the position of Mercury in the 18th century, they interpreted the results assuming a Euclidean background, because they did not know general relativity. So they measured $r$ ...

The limit of GR with infinite speed of light $c$
Just answer what you can. I don't mean the zero curvature flat space time version. I know that the Einstein Field equations use $c$ as a constant, but what would the universe be like if gravity was ...

Violation of Einstein equivalence principle and Galileo Relativity
Two pulleys with one motor with the same force in each one. Between them a half strap or a rope which last sides is glued to each pulley. The force of the motors acts on opposite direction. Each motor ...

Affine space in classical mechanics and it's applicability in general relativity
In the first chapter of Arnold book of Classical Mechanics while giving Galilean structure of spacetime we're introduced to affine space. As already mentioned in answers to this question this is done &...

Absolute Space & Inertial Frames
When we solve the twin paradox we say something like the traveling twin has a Rindler Metric while the stationary twin has a Minkowski metric, or more plainly, the traveling twin experiences non-zero ...

Doesn't spin-spin interactions in gravity disobey Galilean relativity?
In gravity (GR) apparently there are forces which occur which are related to the spin of two masses.
For example if we had a rotating gravitational source and dropped, say, some particles into it ...

How would General Relativity be different if we assumed Galilean instead of Lorentz transformations?
If we assume a universe where Galilean transformations are the correct transformations between inertial reference frames, would GR be any different ? Gravitational and inertial mass would still be ...

What are Galileons good for?
Lately I've seen many papers (for example "The galileon as a local modification of gravity"; 292 total hits on the arXiv) on types of field theories known as Galileons, and I'm wondering ...
