Give me a break you stupid fucking idiot. The sink holes are being caused by the earth's movement. Crustal. There all over the place as well as fissures and land cracks. Uptick in larger earthquakes and Volcano activity. The black holes if you care to read up on them are transiant and last mere mico seconds. Get off this site and go to sceince sites and you may learn somthing about physics or is that over your head. We don't need to go looking for the cause of SINKHOLES. Were sitting on it. Its called mother earth. Fucking stupid people always wanting to stir the pot.
