Without ANY star - highly unlikely considering the amount of stars in a galaxy.
However, the majority of stars will not be hit as the distance between stars is so great. That is the main reason we say galaxies merge, rather than collide.
Over time - billions of years - galaxies will merge with other galaxies. In about 3 billion years, the Andromeda galaxy will merge with our own galaxy, the Milky Way.However, the separation between galaxies is so great, that not all galaxies will merge unless the fundamental issue of the amount of mass in the Universe is determined.If we live in a "contracting universe" then eventually all galaxies will merge.
Galaxies get bigger by a process of merging. The gravitational attraction of the galaxy and the dark matter round it pull in satellite galaxies and these merge with the main galaxy. Eventually large galaxies merge to form large elliptical galaxies. look at the link below.
The answer to this is we do not know but it looks unlikely.The expansion of the universe appears to be speeding up. Local Galaxies might merge into larger galaxies but these galaxies will expand faster and faster away from each other.
and thof
Gravity and inertia, mainly.
Not just dwarf galaxies. Giant elliptical galaxies lie likely the result of many galaxies, small and large, merging.
Not "a" merging galaxy - merging galaxies. Sometimes two (or even more) galaxies collide, and eventually combine (i.e., "merge") into a single galaxy.
Streams often merge with one another to become rivers.
yes they can and if that happens the galaxy will be destroyes :)
merge
they are both galaxies...andromeda being the larger of the two by almost double in size
When galaxies are referred to as cannibals, it means that they can engulf smaller galaxies through gravitational interactions, merging with them and absorbing their stars, gas, and dust. This process of galactic cannibalism plays a significant role in the evolution and growth of galaxies over time.
