I was on my way to school this morning and i suddenly thought of somthing about relativity that has been bugging me ever since. Would i be right in saying that one of Einsteins theories or relativity (cant remember which) says that accelaration is equal to gravity and that the force felt from each is indistingushable. So in the vacuum of space if you accelarate at a certain rate a force is felt pulling you in the direction opposite the accelaration that is equal to the Earth's gravitational constant g (9.81 ms^-2). So if you accelarated at double this rate then the force acting in the opposite direction of the accelaration would be about 20ms^-2. If you accelarated at this rate towards the Earth then the force acting due to gravity would be 10^ms-2 and the force due to accelaration would be 20ms^-2 in the opposite direction. The resultant force acting on the object would be 10ms^-2 in the direction opposite the Earth's gravatational pull and Newtons laws of motion state that an overall force acting on an object causes accelaration in the direction of the force so it would cause accelaration in the direction opposite the earth. I know i must have missed somthing and it is probably staring me right in the face but any help would be greatly appreciated.
