Other possiblities

1. We are looking into an end point of a worm hole, either naturally occuring or created by other beings traveling to our solar system
2. Alien Mothership/Star Cruiser
3. Spontaneous fusion/fission reaction from unstable elements
4. Fusion/fission/chemical reaction from NASA slamming it for research
this is an interesting theory
5. The Sun is acting as a radio tower and the "comets" mass is in a "right spot/time" acting as a reciever in harmony with the Sun radiating solar energy. Just like Nikola Tesla had done with electricity.
6. A severe gravity distortion spinning large amounts of energy and mass. Like a vortex spinning in and out together. The "Bow Tie" look from hubble pics supports such a theory
7. Energy from another dimension/Zero-Point Energy is bursting through
8. The beginning of the alignment with the Galaxy center coming in 2012 (whether that be 2007 or 2012, depends on calender)
9. A form of life. Either supernatural or mortal
10. A device built by our ancestors timed to go off signalling something
11. A secret human spaceship catastrophically being destroyed
12. A gravity/magnetic knot bursting. Just like solar disturbances

I'm deeply interested by #5. I read a lot about Nikola Tesla and this could very well be a frequency anomaly. Several pages earlier in this forum I remarked about the sun expressing a strange vibration seen in a SOHO image with link to pic. Somehow Zero-Point Energy might be involved as well.

I can get with a few of these possibilities...we shall soon see.

Unfortunately, it is rainy and cloudy tonight so I guess I can't look for the first time.
