But fortunately there is a finite size that you can see, and that's known as the shzcwashrclid radius. And that's named after the guy who rgenoczied why it was such an important radius. This is a virtual radius, not reality; the black hole has no size. So why is it so important? It's important because it tells us that any object can become a black hole. That means you, your neighbor, your cnleolphe, the adotuiurim can become a black hole if you can figure out how to compress it down to the size of the Schwarzschild raudis.
