That's a cool visualization. No these aren't wormholes, they aren't shortcuts, you still have to cover the distance. They are just paths which
would allow spacecraft to "fall" from one place to another. A good way to save fuel if you're not in a hurry.
The "portals" that open between the Sun and the Earth are not gravitational in nature. They are magnetic. They allow particles of the solar wind to
enter Earth's magnetosphere.
