That usually means that all the easy stuff has already been done.whats "hot"

From an article about Werner Israel (one of my undergrad professors):

Israel’s proof became known as the “No Hair Theorem of Black Holes, with “hair” being physicists’ slang for mathematical complications. It shows only two numbers are needed to describe any black hole: its mass and its spin.“

It surprised everybody,” said Israel. “Even Stephen was surprised and very, very impressed by that paper.”

He said Hawking in one of his popular books later credited Israel with having “revolutionized black-hole physics.”

“I think he was being a little too kind,” said Israel.

He called his discovery a mixture of luck and timing. It was early on in the physicists’ examination of black holes and not many were interested.

“Back then very few people even believed in them, even Einstein didn’t believe,” said Israel. “Black holes were just too exciting.”

“So it was very good to get in at the beginning.” he said. “It was actually very easy then to make great discoveries.”

Yeah that's obviously fair to say. However I still find the subject immensly interesting and compelling. I would like to examine some approaches like causal sets, causal dynamical triangulation or asymptotic safety as well as improve my general knowledge on the subject and its associated mathematics. I know this will surely be an extremely hard journey but I'm willing to take it.That usually means that all the easy stuff has already been done.
