G Force - what is the max G Force the human body can sustain and for how long.

Question

I have heard so many theories about how much we can sustain under G Force. I've heard 4g is the max, however stunt pilots pull up to 9 G's although not for very long. At some point, we pass out due to lack of blood flow. Does anyone know the answer accurately. Thank you.
