we don't know yet but wait until 2012 comes
A Comet is a body in perpetual orbit. A Meteorite is a body which enters the Earth's atmosphere. It is unlikely that Halley's Comet will ever crash into the Earth.
The solar system (the planets, the earth and the sun) is a part of the milky way, and rotates with the other stars the milky way consists of. The milky way is therefore not going to collide with the earth.
NO.
It may, or it may not. There is no particular reason to assume that a comet will crash into Earth precisely in 2012.
Mothership zeta is not on earth it is orbiting space the only way to get there is by going to the alien crash site and being abducted
No
No.
no
No. The movie "Battlefield Earth" is fiction - BAD fiction - and has nothing at all to do with reality. Also, there is no "Planet x" that's going to crash into the Earth, or make a close approach to Earth. This is entirely fictional as well.
Probably not, there is no Crash game being worked on at the present.
There have been reported crash sights, the most well-documented is probably the Roswell, NM crash in 1947.
A car-crash will be considered a high-speed crash when one or more of the cars involved is going 60 mph or faster. Any slower, and it is not considered high-speed.
