Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the theoretical framework?A solution within Einstein's theory of general relativity
2. What is the mathematical origin?Appears in the maximally extended Schwarzschild solution for eternal black holes
3. What is a white hole and how is it different from a black hole?A white hole is a theoretical region of space that only lets matter, energy, and information escape. Unlike a black hole, where nothing can leave once it crosses the event horizon, a white hole’s horizon blocks anything from entering.
4. Can white holes actually exist in our universe?Scientists have no evidence that white holes exist. They are only solutions that appear in the math of Einstein’s equations, and no known process can create one.

General Relativity: Einstein's geometric theory of gravitation, describing gravity as a property of spacetime.
Event Horizon: A boundary in spacetime beyond which events cannot affect an outside observer.
Schwarzschild Solution: The simplest exact solution to Einstein's field equations, describing a non-rotating, uncharged black hole.
Astrophysical Processes: Natural phenomena occurring in space, such as stellar collapse or galaxy formation.
