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 date of bet initiation?July 1997
2. What is the primary scientific domain?Black Hole Thermodynamics, Quantum Gravity, and the Information Paradox
3. What was the Thorne–Hawking–Preskill bet about?It was a wager between three scientists about whether information that falls into a black hole is lost forever or can be recovered. They argued over the idea that black holes might destroy information or keep it hidden in the radiation that comes out.
4. Why did Stephen Hawking think information could be lost in a black hole?Hawking's calculations showed that black holes emit random thermal radiation, which seemed to erase the details of the matter that fell in. This made it look like the information was gone.

Unitarity: The principle in quantum mechanics stating that the evolution of a quantum system is reversible and information is conserved.
AdS/CFT Correspondence: A duality in quantum field theory relating a gravitational theory in Anti-de Sitter space to a conformal field theory on its boundary.
Information Paradox: The apparent contradiction between general relativity's prediction of information loss in black holes and quantum mechanics' principle of unitarity.
