A White Hole is a made-up object in space that throws anything that enters its area out with lots of force. White Holes have never been found, but many scientists say it's possible. The only problem is the fact that they would instantly explode because the core is what controls the gravity, and anything that gets thrown out. The core is inside the star, so the star would explode with huge force, since gravity is stronger the closer you get to the core. The only reasonable way to enter a White Hole is to use a wormhole, or a rip in space that lets you Time travel. Stephen Hawking discovered the idea of the White Hole, and he wanted to tell everybody about it. A white hole has an Event horizon, which is said to be impossible to enter. The anti-gravity is so strong that light can't enter it.
