Lonnie Said:

the Sagitarrius dwarf galaxy is merging with the Milky way and we are in the middle-- will we survive?

We Answered:

This question is an example of how a little knowledge makes some people dangerous.

When galaxies merge, there are almost no collisions between stars. The distances between them are enormous compared with the sizes of the stars themselves. Did I say "enormous"? There isn't a word to describe the difference, unless it's "Astronomical", but you don't seem to understand what that word means.

"Our system will be shifting gears and begin to flow with the Milky Way in the process of being absorbed". What the hell does that mean?

"It is known fact that a complete other solar system will be raining down directly over top of us". No. If there was something that large only 4 years away, we'd have seen it decades ago.
