Interesting article at Phys.org. A team of researchers putting for a write up on to what the nature of black holes may actually be:

"In their analysis they found that these topological solitons are stable defects in space-time itself. They require no matter or other forces to exist—they are as natural to the fabric of space-time as cracks in ice."

Somehow I find a bit of elegance to this theory if it pans out.
