Now the funny part! The wormhole is just a sphere which I made an extrusion inwards and then I inserted the faces which naturally created a pinch lol.
Applied to the Inner Part a PBR Metal 1, 0 Roughness to that faces giving this “distorted effect”. The rest of it it’s a mix of refraction + emission with Wave texture and same wave to the Displacement.
The fire of the engines are just planes 2 planes in X formation with some odd material I created lol
