gravity changes???

i've heard this from my inlaws--one was a college professor chemist, and the other is a NIH scientist (yes, i do wonder what they think of me ).

apparently the more you chase the laws that we think govern our little fish tank of a world/universe, the more things start to change a bit and loosen what was previously accepted as a law.
[that was my background info]

gravity is supposed to be one of those things. i don't understand this concept. what happens to it? i guess this is some metaphysics stuff. and no, i'm not going to ask them...again. i was happily moving along thinking of sir isaac newton with an apple on his head and a small 'ouchie'.

Yes, the earth’s gravity fields are constantly changing. They always have and I suspect always will. At some point in the future the poles will actually switch as they have many times in earth’s history. Some say this is occurring now and can possibly be justified through the South Atlantic Anomaly where north is not really north http://en.wikipedia.org/wiki/South_Atlantic_Anomaly

The earth's magnetic fields and gravity are separate.One is not the other.

all i (think i) understand is that our world works by laws that sort of bend as one approaches the limits(whatever that means) of the parameters of our universe from which we draw those conclusions. i sort of got interested because i like the way we (society) try and find finite meaning in an attempt to not lose our minds, and the closer we get to thinking, "oh yes, now i have all the answers", apparently nature/spirituality/whats-in-a-mc'donald's-burger/etc...turns around and says, "eh-eh...and now for something completely different", which in the case of the mc'donald's burger might be pink hairy shit.

The current scientific theory which describes the force of gravity is Einsteins General Theory of Relativity.He puplished this in 1915,ten years after his other theory of relativity,The Special Theory of Relativity.
General Theory of Relativity helps described observed effects which could not have been described by the previous best theory of gravity,that was Newtons Theory of Gravity.
Scientific theories sometimes have to be modified and/or rewritten to fit into the observed/measured evidence that is collected.Thats the way science is.
I think that is what you were wondering about changes in gravity.
