Can General Relativity and Special Relativity be unified?
The two theories are not the same at all, and they should not be unified. Both of them are relevant to different situations.
Special Relativity is the theory of how things move relative to other, and General Relativity is the theory of curvature in spacetime. They are two independent ways of approaching very different situations.
When you are considering a situation in which things move relatively to others, you need the theory of Special Relativity. If they do not move relative to other entities, then it is better to use General Relativity.
They are two different ways of looking at the same situation. They should not be unified because they do not tell you to look at things in the same way, and they can only give conflicting information.
For instance, if you were to consider a situation where things are moving relatively, then the speed of light can be different for them when viewed from an inertial reference frame in which they are not moving.
If they are only moving relative to each other, then the speed of light will be different for them in the two reference frames.
