Does Einstein need gravity to define gravity?

VITEEE Preparation › Class VII-X Physics questions › Does Einstein need gravity to define gravity?

Look at the image I have uploaded. The Earth is pushing the space layer. Einstein used this to define gravity. He said that if an object of smaller mass would be somewhere around the space where the earth made the layer hollow, it would naturally fall down to the one with greater mass. But, for this, the layer must also have gravity. Now, how will this layer get gravity and from where will it get?

Albert Einstein developed the first revision of these ideas. Einstein needed to extend his theory of Special Relativity to be able to understand cases in which bodies were subject to forces and acceleration, as in the case of gravity. According to Special Relativity, however, the instantaneous gravitational effects in Newton's theory would not be possible, for to act instantaneously, gravity would have to travel at infinite velocities, faster than the speed of light, the upper limit of velocity in Special Relativity. To overcome these inconsistencies, Einstein developed the theory of General Relativity.
