I'm pretty new to physics, and have just started really getting into it the last year or so, but I had an idea about the anatomy of a black hole.
I was wondering if it were possible that a black hole could be made of compressed matter, in a spherical shape, instead of a "hole."
Or if it were possible that the extreme gravity could somehow cause a fusion-type reaction that could turn physical matter into pure energy, which may explain the "halo" that seems to refract around the outer edges, while still pulling in light. And If this whole theory may be able to explain how particles, or radiation can also be ejected from the event horizon.
Like I said, I'm new to physics, and am still learning, and would love to make a career out of it someday, but I felt I should try and get involved more.
