Distinguishing Black Holes From Naked Singularities
A new theoretical paper from researchers at the Harvard-Smithsonian Center for Astrophysics finds there is a way in principle to make a black hole with no event horizon, a so-called "naked singularity." Black holes with masses of millions or even billions of suns appear to reside at the nuclei of Feb 17, 2014 ... Such an object is called a “naked singularity” (“singularity” because, like a black hole, it has point-like dimensions, but naked because it ... [ReadMore..]

Was The Big Bang Just A Black Hole? - Universe Today
Fraser “Asks a Spaceman” Dr. Paul Matt Sutter – why do we call the Big Bang a singularity, when we also call black holes singularities? The Universe is filled with coincidences. Like the size of the Moon and the Sun in the sky, even though they’re so far apart. Or the shape of the Pac … Continue reading "Was The Big Bang Just A Black Hole?" Feb 15, 2016 ...

Towards An Observational Test Of Black Hole Versus Naked Singularity ...
While the event horizon of a black hole could cast a shadow that was observed recently, a central singularity without horizon could also give rise to such a feature. This leaves us with a question on the nature of the supermassive black holes at the galactic centers, and if they admit an event horizon necessarily. We point out that observations of motion of stars around the galactic center should give a clear idea of the nature of this central supermassive object. We examine and discuss here recent developments that indicate intriguing behavior of the star motions that could possibly distinguish the existence or otherwise of an event horizon at the galactic center. We compare the motion of the S2 star with these theoretical results, fitting the observational data with theory, and it is seen that the star motions and precession of their orbits around the galactic center provide important clues on the nature of this central compact object.
