Anywhere door, for now, is just a science fiction idea. But can be developed in the future using the concept of a wormhole that is interlinking of space-time to create a tunnel through space-time.
For a long time, human civilization has thought that space is a solid stage. According to them, space has no effect on the planets and other celestial bodies.
This is true until the proposal of Einstein’s theory says that space-time are interconnected and they form the stage for the celestial bodies.
According to him things on the stage i.e., celestial bodies, have an effect on space stretching and warping the space around them which is proportional to the mass of the celestial bodies.
Now that we came to a conclusion that space is curved based on Einstein’s theory. If we consider our universe is not in a plane shape.
Then we can try to build a tunnel that tunnels through space-time connecting the parts of the universe light-years away into a simple walkable distance.
Allowing us to travel faster than light. But it is still a concept as of now.
