I thought an object with mass could not reach the speed of light in any frame of reference though? Or is that invalid in a curved spacetime?

We know that the escape velocity at the schwarzchild radius is c. Since the escape velocity is defined as the velocity needed to escape from the gravitational field, to reach a total energy of 0 at infinity: Doesn't this mean that an object falling from infinity starting at rest, to the...
