INTRO: There are few places in the universe that invite as much curiosity—and terror—as the interior of a black hole. These extreme objects exert such a powerful gravitational pull that not even light can escape them, a feature that has left many properties of black holes unexplained.

Now, a team led by Enrico Rinaldi, a research scientist at the University of Michigan, have used quantum computing and deep learning to probe the bizarre innards of black holes under the framework of a mind-boggling idea called holographic duality. This idea posits that black holes, or even the universe itself, might be holograms.

“The new techniques do not directly investigate the idea of the universe as a holographic projection,” Rinaldi said in an email. “If a black hole can be described by the holographic duality, then we believe that the gravity in our entire universe could be also described by holography.”

“However, this last step is still under intense research and it is not directly related to the techniques we presented,” he noted. “Our techniques make difficult computations possible and provide tools to test the idea that the universe is a hologram in the future.”

To that point, Rinaldi and his colleagues employ so-called “matrix models” to examine the mysterious behavior of gravity at quantum scales, known as quantum gravity. The researchers believe that these computational techniques could become “the new Swiss army knife” of quantum gravity studies, according to a recent study published in the peer-reviewed journal PRX Quantum.

The new research is the latest iteration of a decades-long effort to square the laws of physics on cosmic and quantum scales... (MORE - missing details)
