general relativity - Is the stress energy tensor continuous at the interface between an object and vacuum?


The stress energy tensor has (as I understand) zero value in the region where there is no matter and non-zero value where there is matter. Suppose there is one matter object in space, now how does the value of the stress energy tensor change as we go from inside of the object to outside, is it a continuous change or does it jump to zero?
