Does infinite speed of gravity in Newton's theory imply infinite distance or time?

[MathematicalPhysicist]

i read in scientific american that in Newton's theory of gravity the speed of gravity was proposed to be infinite.
my question isn't this implying that the distance and/or time are also infinite (if so, doesn't it defie Newton's theory[and thus contradict itself]?)?

Infinite speed of gravity is fine with Newton, it only runs into trouble with Einstein.
