Astronomy & Space - May 2007

ive been reading a lot of articles about asteroid global killers and i still don't believe that a 1 or 2km wide asteroud could cause an extinction. Some scientists says that a 100 km wide craters didnt cause extinction and now they are saying that a 1km wide asteroid enough to create a 10 to 20 km wide asteroid could cause an extinction ..... this scientists are really dumb

I'm making a model on Jupiter and I know it has a ring around it but I'm not sure if it's visible or not? Thanks
I've seen pictures and It doesn't have the ring but should I still include it?

I recently read that when mattter and antimatter meet, they annihilate and revert back to pure energy, and that it is possible that anntimatter gallaxies even still exist in our universe, but that such gallaxies would innevitably collide with gallaxies of matter and create huge amounts of gamma ray energy that would hurl out from each other in two huge rays.

Now this sounds exactly like what i've read of gamma ray bursts. How about it you physicists out there? Could that be what causes the gamma ray bursts that are still really unexplained occurances of enormous energy output?

A couple years back, I use to watch many specials on this issue, and they said anything over a 1/2 Kilometer could destroy all life.

1b) And could you feel it if it hit on the other side of the world?

1c) We only know about 10% of earth killing objects, which is a small amount considing the amount that is out there. How close could a earth killing object get before we would take notice, or is it possible for it just to hit with out no warning at all, expect for when you seen it in the sky?

PLEASE ONLY ANSWER WITH REAL NUMBERS, PLEASE NO QUESSING ON THIS ONE! THANK YOU
