Astronomers tells us that when galaxies collide no spectacular explosion take place the two galaxies simply pass to each other explain why is this so?

Galaxies are mostly empty space. Even in our neighorhood in the middle of an arm of the Milky Way galaxy, there are no more than 20 stars within 10 light years from the Sun. That is very sparse.
Imagine shooting two shotgun blasts at the same point from two locations 200 meters apart, do you think that any of the shot would hit each other? The stars are much less dense than a shotgun swarm at 100 meters (2 meter radius is tight at that distance).

How do computers help astronomers understand what happens when galaxies collide?
By translating the math model of a galaxies and a galaxy collisions into a simulation. And theoritically observe the process by experimenting with the variables.
What happens when stars calide?
When stars collide they connect their galaxies and explode.If our earth was at the far end of the explosion we would survive but if we were in the middle the explosion would be too intense for anyone to survive.
When galaxies collideno spectacular explosions take placethe two galaxies simply pass through each otherexplain why this is so?
A galaxy is 99.999% empty space; they aren't actually solid. The only time you would see a "spectacular explosion" would be if individual stars within the galaxies were to collide. Which isn't to say that they would pass right through each other; the one thing each galaxy does have is what keeps it together as a galaxy; gravity. When two galaxies collide (which apparently is not particularly uncommon; we have photos of several sets of galaxies that are even now in the middle of their own collisions) each star within the galaxies falls under the gravitational influence of not only the other stars in their own galaxy but also all the gravity of all the stars in the other galaxy. The stars are bent away from their normal paths, each deflecting the other, until they swirl together - or are flung away from the galaxy and into deep space. In fact, many astronomers claim to have identified the traces of at least a few other galaxies within our own; the Milky Way has apparently swallowed some other galaxies.
Do galaxies ever meet?
Yes. Galaxies do sometimes collide.

galaxies are mainly created out of gases and cosmic dust, so they can't crash. only individual bodies inside a galaxy can crash together
What happens when two spiral galaxies collide with each other?
You tend to end up with irregular galaxies
When stars collide how big of an explosion is it?
Stars very rarely collide. Space is too big for that to happen.
Can galaxies steal stars from one another?
Not generally, but galaxies do collide sometimes. In fact, the Andromeda Galaxy will probably collide with the Milky Way in about 3 billion years or so. In the collision, stars are often "flung" from one galaxy to the other, or thrown out of the original galaxy entirely. Follow the link below to see what happens when galaxies collide!
What happens when two suns collide?
a big explosion occors
What is one way that an elliptical galaxy differs from the other types 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.
What happens if 10 galaxies collide into each other at the same timeHow big would the supernova be?
When galaxies "collide", the individual stars do not actually smash together; they're far enough apart that they mostly slip past each other.
What is a merging galaxy?
Not "a" merging galaxy - merging galaxies. Sometimes two (or even more) galaxies collide, and eventually combine (i.e., "merge") into a single galaxy.
