There is, however, an initial impact that happen almost instantly.Originally Posted by Raistlin
Through what? The invisible ropes connecting everything? The only thing that connects the Milky Way is gravity. Therefore, a large body from the galaxy first has to get close enough for its gravitational field to impact the Earth's orbit around the sun. That would be the "initial" change. If the edge of one galaxy starts going through the edge of the other side of the Milky Way, the Earth won't "feel" a thing.
There's also no such thing as "instant."
There's also the force of buoyancy, which opposes gravity by keeping objects from sinking.>>> That and Dark matter, which is actually like invisible ropes connecting everything..
Most certainly indeed.
That has been discussed before; we might end up colonizing other planets, but are we alone in this universe?
