Physicists have come up with a new way to predict what lies beyond the event horizon of a black hole, and it could give us a more accurate idea of their mysterious internal structures.
Studying black holes is basically like doing science backwards. Usually you’ll observe something strange and new first, go and analyse the crap out of it, and come up with an hypothesis to explain and classify it – possibly with the help of some complicated mathematics.
At the 228th meeting of the American Astronomical Society in San Diego, the team reported that there are 17 such quantities related to the curvature of space-time that can be used to study black hole interiors. Because of certain mathematical relationships between them, they say only five are truly independent.
They have Published their report on arxiv.org which is given below;
Black holes are real astrophysical objects, but their interiors are hidden and can only be “observed” through mathematics. The structure of rotating black holes is typically illustrated with the help of special coordinates. But any such coordinate choice necessarily results in a distorted view, just as the choice of projection distorts a map of the Earth. The truest way to depict the properties of a black hole is through quantities that are coordinate-invariant. We compute and plot all the independent curvature invariant of rotating, charged black holes for the first time, revealing a landscape that is much more beautiful and complex than usually thought.
