> the time and space axis gets flipped at the event horizon. This also happens to a fast moving objects due to relativistic effects
Neither of these things are true, and I have no idea how you are getting either of them from the Wikipedia article you linked to. Penrose-Terrell rotation, which affects how objects appear to observers when they are moving at relativistic speeds relative to those observers, does not "flip" the time or space axes; it's an optical effect due to the finite speed of light.
As I noted in another post upthread, the "flip" of time and space axes inside a black hole's horizon is a property of a particular choice of coordinates, not of spacetime itself.
> This kinda implies time and space are the same thing
No, they aren't, because there is still a fundamental difference between timelike and spacelike directions in spacetime. That is true regardless of how you choose coordinate axes.
People often mistakenly try to map space time onto an ether-like flat background, treating spacetime like a drawing where the paper is the background. It's not an uncommon kind of fumbling as someone tries to grasp these things.
