Difference between Schwarzschild metric and Gravity well.

[Victor Escudero]

I would like to know the difference between this two concepts, specially the difference between the geometry deformations of space-time that they descript. As far as I know the Schawrzschild metric can be represent by Flamm’s paraboloid, but this shape is not the same that the deformation of space-time descripted by the Gravity well. So I would like to know the difference, which one describes exactly de deformation of space-time due to the gravity and if there exist any formulas that can give us the shape of this deformation.

It is unclear what you mean by "gravity well". Do you refer to a well in the gravitational potential? In that case it is only a valid description for very weak gravitational fields and the Schwarzschild solution is a better description (assuming that you want a spherically symmetric distribution) outside of the matter distribution.

Flamm's paraboloid only describes a particular space-like two-dimensional submanifold of the Schwarzschild space-time so neither it nor a gravitational potential well describes the geometry of 4D space-time very well.
