The Mysterious Plane of Planetary Orbits

Why do the elliptical orbits of the planets in our solar system rotate on a single plane.

Because they were all formed from a single disk. The plane is also the equatorial plane of the sun.

Oh, I see so there are no external forces that would cause the planets to go up or down out of the orbital plane. Is there any type of 3-d graphic phys let out there that shows this process from the beginning to the forming of the planets.

Not all the planets are in the same plane, their orbit planes can be tilted a bit. Probably because of impacts in the past. Impacts also are believed to be the reasons for eccentricity of the orbits
