What is Singularity in Science

In the centre of a is a , a one-point which contains a huge in an infinitely small space, where and become infinite andcurves infinitely, and where the laws of physics as we know them cease to operate. As the eminent American physicist Kip Thorne describes it, it is "the point where all laws of physics break down".

Current theory suggests that, as an object falls into a and approaches the at the centre, it will become stretched out or “spaghettified” due to the increasing differential in on different parts of it, before presumably losing dimensionality completely and disappearing irrevocably into the . An observer watching from a safe distance outside, though, would have a different view of the event. According to , they would see the object moving slower and slower as it approaches the until it comes to a complete halt at the , never actually falling into the .

The existence of a is often taken as proof that the theory of has broken down, which is perhaps not unexpected as it occurs in conditions whereshould become important. It is conceivable that some future combined theory of (such as current research into ) may be able to describe without the need for , but such a theory is still many years away.

According to the "cosmic censorship" hypothesis, a 'sremains hidden behind its , in that it is always surrounded by an area which does not allowto escape, and therefore cannot be directly observed. The only exception the hypothesis allows (known as a “naked” ) is the initial itself.

It seems likely, then, that, by its very nature, we will never be able to fully describe or even understand the at the centre of a . Although an observer can send signals into a , nothing inside the can ever communicate with anything outside it, so its secrets would seem to be safe forever.
