I'm facing a problem in my physics course which is accepting that infinity can be a reference point in both Electrostatics (calculating the voltage of a point) and Matter Properties (calculating the gravitational potential energy), how come we use a reference point which we don't know where it is, keep in mind that I don't have any problems dealing with infinity when we plug it in a mathematical relation, what I want is to understand the physical concept of choosing infinity as a reference.
