ok tell me why F=ma
Newton had only told , F is directly proportional to rate of change of linear momentum
to omit the sign of proportionality he needed a constant k
and experimentally after many attempts it was found that k=1
similarly
value of G which is also a constant term that replaced the sign of proportionality so its value doesn't change ..

A constant does not depend on anything, its a value. Its not a characteristic of a particular phenomena or define any process.
Its simply a value which is fixed anywhere and anypart of the universe. Just as mass of a body is fixed, be it on the earth or be it in the moon or be it in some other galaxy. Its fixed. But what changes is its weight in different situations, such as a body have different weight on earth and different on moon.
So to sum up in one sentence, it is independent.
You are telling me that which you are feeded in your brain ...use your brain and ask the question why it is constant... ?? Why can't it change?
