    Singularity
In summary, there are different interpretations of the singularity of a black hole, with some arguing that it is not a point in space-time and others believing it is. This has led to alternative models that do not have a singularity at the center of a black hole. These models are still being researched and debated.

It has been claimed that,
"The singularity of a black hole is not a point in space it is not even a point in spacetime, in fact it is not even in spacetime. The singularity is not a point on the spacetime manifold. If it were it would obviously not be a singularity."
The source is unimportant.

I feel that a singularity is technically any location--in space-time--where properties, namely density, become infinite. And less technically, any location that we don't really feel can exist according to the understandings of generally excepted theory (i.e. infinite density again, information loss, blah blah blah).
Colloquially, a gravitational singularity has become synonymous with black-holes (perhaps unfortunately), in which case a black-hole (the juicy core in particular) very possibly occupies a finite, non-zero, region of space-time.

Is there any backing to "singularities" not occupying space-time?
If this is the case, how can they come into existence, and later(temporally) cease to exist?
How can they interact with space-time?

Cheers.

Hi Iskelley,

Most textbooks regard a black hole as a point singularity. That is one conclusion drawn from general relativity (that Einstien did not agree with) but there are other alternatives that interpret the conclusions of GR differently. If you want to the explore them you can start at the wikipedia article titled "Nonsingular black hole models" here http://en.wikipedia.org/wiki/Nonsingular_black_hole_models and perhaps also refer to post#32 of the "Gravitational Redshift" thread here: https://www.physicsforums.com/showthread.php?t=234292&page=3

The nature of singularity semantics is a topic that has been heavily debated and is still not fully understood. In simple terms, a singularity is a point where the properties of a system become infinite or undefined. In the context of black holes, the singularity is often described as a point of infinite density and gravitational pull where the laws of physics break down.

The statement that the singularity is not a point in space or spacetime is based on the idea that a singularity cannot be described within the framework of our current understanding of spacetime. It is not a physical object that can be located in a specific location, but rather a mathematical concept that represents a breakdown in our understanding of the laws of physics.

One way to think about this is to consider the singularity as a limit in spacetime. Just as the limit of a function can approach infinity or become undefined, the singularity represents a point where the properties of spacetime become infinite or undefined.

There is no concrete evidence or backing to suggest that singularities do not occupy space-time. However, the concept of a singularity is still not fully understood and there are ongoing efforts to reconcile it with our current understanding of spacetime.

As for how singularities come into existence and interact with spacetime, these are still open questions that scientists are working to understand. Some theories suggest that singularities may be formed through the collapse of massive stars, while others propose that they may be remnants of the Big Bang. The interaction of singularities with spacetime is also a subject of ongoing research, with some theories proposing that they may have a significant impact on the structure and evolution of the universe.

In conclusion, the nature of singularity semantics is a complex and ongoing topic of research in the field of physics. While there is still much to be understood, it is clear that singularities represent a fundamental breakdown in our understanding of spacetime and the laws of physics.
 

What is the Nature of Singularity Semantics?

Singularity semantics is a branch of linguistic study that focuses on the meaning of words and phrases in a language. It specifically looks at how singular terms, such as proper names, refer to specific objects or individuals in the world.

What is the difference between Singularity Semantics and General Semantics?

The main difference between singularity semantics and general semantics is their scope. Singularity semantics focuses on the meaning of singular terms, while general semantics encompasses a broader range of linguistic concepts, including sentence structure, truth conditions, and reference.

How does Singularity Semantics relate to Philosophy of Language?

Singularity semantics is closely related to philosophy of language, as it deals with questions about the nature of meaning and reference in language. It is often used to analyze philosophical issues, such as the nature of proper names and their relation to the objects they refer to.

What are some key theories in Singularity Semantics?

Some key theories in singularity semantics include direct reference theory, which posits that the meaning of a singular term is its referent, and descriptivist theories, which argue that the meaning of a singular term is a description or set of descriptions that uniquely identify the referent.

How does Singularity Semantics impact our understanding of language?

Singularity semantics helps us understand how language is used to refer to specific objects or individuals in the world. It also sheds light on issues such as the relationship between language and reality, and how we can use language to accurately describe and represent the world around us.
