Black Holes beyond that impenetrable darkness

The Weak Cosmic Censorship Hypothesis Insists That There Are No Naked Singularities In The Universe Except The One That Arose In The Wake Of The Big Bang, And That The Event Horizons Of Black Holes Must Obscure Their Singularities.

New Delhi:

What lies in 'Black Holes' and behind it? Well, this is still a mystery and there is no spacecraft in the existence.  An inactive, invisible black hole, which is four times the mass of the Sun, has been discovered by the scientists by observing a strange star orbiting it. 

An almost sci-fi study published in Physical Review Letters by UC Berkeley postdoctoral fellow Peter Hintz and colleagues could mean that there are black holes out there that would be more like portals than gaping mouths of destruction — if you didn’t mind your entire past being erased and entering into infinite futures.

“No physicist is going to travel into a black hole and measure it. This is a math question. But from that point of view, this makes Einstein’s equations mathematically more interesting,” Hintz said. “This is a question one can really only study mathematically, but it has physical, almost philosophical implications, which makes it very cool.”

Enter cosmic censorship. The weak cosmic censorship hypothesis insists that there are no naked singularities in the universe except the one that arose in the wake of the Big Bang, and that the event horizons of black holes must obscure their singularities. It’s believable. It’suncomplicated. It lets you sleep at night.

“There are some exact solutions of Einstein’s equations that are perfectly smooth, with no kinks, no tidal forces going to infinity, where everything is perfectly well behaved up to this Cauchy horizon and beyond,” said Hintz. “After that, all bets are off.”
