They would become distorted due to gravitational affects
It is a large galaxy, which is relatively near-by. There are galaxies nearer to us, like the two Magellan Clouds; but those are mini-galaxies.
An airprox is a near-miss between two aircraft.
No.
a galaxy cluster is started but stars pass by each other but they dont go boom
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.
The two Magellanic Clouds are irregular dwarf galaxies.
the two types of galaxies that are barred and normal would be irregular as my best guess
This could not happen because the Earth is located within the Milky Way galaxy. Intergalactic stars are located outside of Galaxies.
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
You should be thinking "don't miss the toilet, that won't happen again."
For starters, if there were no separation between two (or more) galaxies, it would be considered a single galaxies, not two or more. The reason matter is clumped together into galaxies at all (with separations in between) is because of gravity - gravity tends to do that, i.e., to clump things together.
The force that draws two galaxies towards each other is gravity. The gravitational force between the two galaxies pulls them towards each other and can cause them to collide or interact.
