Physicists are reshaping our understanding of black holes<\/a> in new research that maps theoretical structures within them known as \u201csupermazes,\u201d offering an unprecedented look at their microstructure.<\/p>\n

Black holes remain one of the universe\u2019s most fascinating features<\/a>, since they are so gravitationally dense that nothing\u2014including light\u2014can escape them. Now, a team of physicists report how supermazes within black holes, a concept drawing from string theory, could play a crucial role in helping us understand the structural elements of these cosmic singularities at the microscopic scale.<\/p>\n

Offering a more detailed picture on black holes and their relationship to other cosmological phenomena<\/a>, Nicholas Warner, a professor of astronomy and mathematics at the USC Dornsife College of Letters, Arts and Sciences who co-authored the new study, says the team\u2019s findings could help to fill in some of the missing theoretical pieces that Einstein\u2019s theory of general relativity<\/a> can\u2019t explain about black holes.<\/p>\n

\u201cGeneral relativity is a powerful theory for describing the large-scale structure of black holes, but it is a very, very blunt instrument for describing black-hole microstructure,\u201d Warner said in a statement.<\/p>\n

Supermazes, by contrast, help to carry theoretical physics approaches to unraveling the black hole mystery beyond where Einstein left off with general relativity, offering physicists a chance to explore the microscopic structure of black holes. This is important because black holes must have an extensive microstructure when considered in terms of quantum gravity<\/a>.<\/p>\n

Supermazes and Fuzzballs<\/strong><\/p>\n

Substituting more conventional notions of black holes with objects known in string theory as \u201cfuzzballs\u201d is one way of achieving this. Warner and his colleagues argue that fuzzballs can be constructed theoretically using supermazes of physical objects that exist in a higher spacetime dimension.<\/p>\n

The incredible result, Warner says, is the creation of an object that exhibits its entire structure, all while still behaving like a black hole.<\/p>\n

Using general relativity to achieve what he and his team seek to accomplish would be like using a camera armed with just a single pixel to capture an image of Michelangelo\u2019s famous painting, The Last Judgement,\u00a0which would provide only a pinpoint of color from the painting.<\/p>\n

\u201cOur earlier work gave us a picture with maybe 1,000 pixels: outlines of structures and some of the shading,\u201d Warner says. By contrast, employing supermazes is comparable to \u201chaving many, many billions of pixels enabling us to admire the masterpiece in detail.\u201d<\/p>\n

Building a Black Hole in M-Theory with Supermazes<\/strong><\/p>\n

Warner and the team\u2019s work focuses on M-theory, which unifies all the consistent versions of superstring theory in modern physics by positing that the fundamental \u201cstrings\u201d of the universe aren\u2019t one-dimensional, but instead exist as membranes, otherwise known to physicists as \u201cbranes,\u201d in higher dimensions. These objects can traverse multiple spatial dimensions, featuring surfaces that hold an important place in both M-theory and string theory<\/a>.<\/p>\n

Warner and his team focused their study on the intersecting systems of M2-branes and M5-branes (the latter being five-dimensional when compared with the two-dimensional former variety) all in relation to supergravity as an approximation of M-theory.<\/p>\n

\u201cWe think of the maze as the \u2018substrate\u2019 upon which all the information about whatever made the black hole, or ever fell into it, can be encoded,\u201d Warner explained. Their investigations into the maze function at the heart of the intersections between branes offered useful insights for the team into how mazes can reproduce black hole entropy, and may potentially even describe their microstates.<\/p>\n

Maze Functions and Supergravity Solutions<\/p>\n

Although the intersections of branes are nothing new in the study of string theory, these ideas are taking on new life in Warner and his colleagues\u2019 work, offering new perspectives, as well as unique geometries that can be used to detail the behavior of black holes. Newly presented in the team\u2019s research, however, is a unique mathematical construc called a \u201cmaze function\u201d that they use to characterize solutions for intersecting systems of M2 and M5 branes in supergravity.<\/p>\n

\u201cMaze functions play a pivotal role in linking the brane configurations to supergravity solutions, which in turn provide a new way to explore black-hole microstates,\u201d Warner said. According to the team\u2019s findings, this maze function has to conform to equations similar to the famous Monge-Amp\u00e8re equation which relates to M2 and M5 brane intersection geometry and other characteristics.<\/p>\n

\u201cThe maze function is the billion-pixel camera that can give us a deep and detailed picture of the microstructure of black holes,\u201d Warner said, adding that the team\u2019s work is a first step toward developing a more complete description of the microstructure of brane black holes in string theory.<\/p>\n

The team recently reported their findings in a study in the Journal of High Energy Physics.<\/p>\n
