Understanding Black Hole Singularity

In summary, the conversation discusses various theories and opinions on the existence and formation of a singularity at the center of a black hole. While some believe that a singularity is necessary for the formation of an event horizon, others argue that it is a mathematical artifact and may not actually exist. The properties of a hypothetical singularity are also debated, with some suggesting it could be a single supermassive particle with quantized properties such as mass, volume, charge, and spin. However, it is agreed that the gravitational consequences of events within a black hole take longer and longer to ripple out to the world at large.

Why so many physicists for years accepted GR beyond the Planck wall?

Can you cite a paper where GR is used at sub-Planck scales?

FAQ: Understanding Black Hole Singularity

What is a black hole singularity?

A black hole singularity is a point of infinite density and zero volume at the center of a black hole, where the laws of physics as we know them break down.

How is a black hole singularity formed?

A black hole singularity is formed when a massive star collapses under the force of its own gravity, causing its core to become infinitely dense and form a singularity.

What happens at the event horizon of a black hole singularity?

The event horizon is the point of no return for anything that enters a black hole, including light. At the event horizon of a black hole singularity, the gravitational pull is so strong that nothing, not even light, can escape.

Can we observe a black hole singularity?

No, we cannot directly observe a black hole singularity because it is hidden behind the event horizon. However, we can observe the effects of a black hole singularity, such as the distortion of light and the gravitational influence on surrounding matter.

What are some theories about what happens inside a black hole singularity?

There are several theories about what happens inside a black hole singularity, but none of them have been proven. Some theories suggest that the singularity may lead to another universe or that it may eventually evaporate due to Hawking radiation.
