Practical Component: Schwarzschild radius, event horizon and singularity

Last week, we decided to make different models to show the different methods of collecting energy for the practical component of the project. I am in charge of building the standard structure model of a black hole. Currently I have a few ideas sketched out, which I will include in a later post about the creation process. It would also be nice to incorporate the Arduino somehow. I want the model to be able to suck in surrounding material with a switch and emit the material after with another switch. From my research, I already know that there will be an accretion disk and corona surrounding the black hole. The characteristics of the structure of a black hole seems to be one of challenges modern relativistic astrophysicists face.

So far, reoccurring parts in the current hypothesised structure include the Schwarzschild radius, event horizon and singularity. The Schwarzschild radius is the radius at which the escape velocity equals the speed of light. The event horizon is the surface of the sphere of radius and is synonomous with the Schwarzschild radius. On the outside, humans do not know anything happening inside, so the event horizon is thought of as the surface of the black hole. It is also the point of no return, meaning nothing can escape once it goes past the event horizion. The singularity lies in the center of the black hole, where the current laws of physics do not apply do the extreme conditions.

In the midst of researching I found an interesting video (which also looks really nice).
