. It presented a revolutionary idea: That the more massive something is, the more it alters space around it. And while it sounds simple enough, the theorem actually involves 10 interconnected equations — mathematically speaking, there's just a lot of moving parts. So when it came to applying the theorem to describe how a specific mass distorted a particular part of space, Einstein believed it would be extremely difficult to find solutions that weren't fuzzy approximations.
"So it is actually the shape of space around a clump, like a point mass, like a really concentrated compact mass," says Natarajan."That's the black hole solution."Schwarzchild was really just testing the limits of his equations–a normal practice in math and physics. But by keeping an open mind, Schwarzschild helped expand our understanding of what was possible.
