Do Gravitational Field Lines Exist Similar to Magnetic and Electric Field Lines?

Click For Summary
Gravitational field lines, like magnetic and electric field lines, are mathematical constructs used to describe forces acting at a distance rather than physical entities. They connect massive bodies similarly to how electric field lines connect charges, indicating the direction of gravitational force. The geometry of gravitational and electromagnetic fields is comparable, with both exhibiting radial characteristics emanating from their respective sources. While gravitational field lines can visually resemble those of electric fields, they serve as tools for understanding interactions rather than existing as tangible objects. Overall, gravitational field lines function within the same conceptual framework as other vector fields.

Can they exist ?? Like Magnetic Field lines and Electric Field lines

I think you might be confused by what "exists" means in this context. http://en.wikipedia.org/wiki/Field_line" are often physically significant, they are still just mathematical tools. In that sense, none of them "exist". But the gravitational field isn't any different, in terms of 'having' field lines, from the EM field, or any vector field, really.

Like an Electric field connects one point to the charge to the other..in that context , would a Grav. field line connect any two centre's of gravity?

Also it will always act radially inwards for a particle , so is the geometry similar to other Field lines?

Gravitational field lines "connect" massive bodies as much as electrical field lines do. Field lines are mathematical, they are not physical.

The geometry of the gravitational and EM fields are similar, but there are differences. They are both 'radial' though, in the sense that they come from the mass/charge of the particle.
 
Magnetic and electric fields lines are a model for describing forces which act at a distance, and since gravity acts at a distance it can be described by the same model.

The gravitational field lines from a point mass look identical to the electric field lines of a negative point charge.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
