In a massive galactic collision, the stars much further apart than the water droplets in a rain cloud; the odds that any two stars would collide would be astronomical. However, the number of stars IS "astronomical", in the trillions for a big galaxy like the Milky Way and Andromeda, which WILL collide in about 4 billion years. So it's very possible that at least two such stars will collide, with catastrophic results; in all likelihood, the two stars would start to merge and promptly go nova, destroying them.
But as a general rule, stars don't collide.

∙ 15y agoGalaxies are generally very far apart, and don't move all that quickly, so galactic collisions aren't particularly common. And they take millions of years to collide.
That said, however, astronomers using the Hubble Space Telescope have imaged several galaxies which are either about to collide, are in the middle of a collision, or which have recently separated after a collision.

∙ 9y agoThe answer, I think, is the Anthropic Principle. Large amounts of collissions (with large asteroids) are disastrous for life, so life couldn't develop until the amount of collissions were reduced - once most of the asteroids and meteorites (the "planetesimals") had combined into larger pieces. Note that in the early history of the Solar System, there were much more such collissions.

What is meheorites?
Meteorites are asteroids that strike the Earth.
All meteorites collected on Earth come from asteroids or comets?
False.
Where meteorites came from?
Meteorites can from asteroids that landed on Earth's surface. They were originally chipped off larger planetary bodies by bolide impact.
Most meteorites collected on Earth are of the rocky primitive variety although most asteroids are of the carbon-rich variety?
Most meteorites are rocky and primitive.
Why are there so many meteorites near earth?
There are hardly any comets, meteorites or asteroids near earth. There are only a few that are millions of kilometers from earth. There are a few that pass earth a bit closer because of the asteroid belt between Mars and Jupiter.
What is meheorites?
Meteorites are asteroids that strike the Earth.
What will collide with earth that provides evidence of earth's inner composition?
Meteorites
How asteroids and meteorites linked?
A meteorite is an asteroid that is pulled into the Earth's atmosphere.
All meteorites collected on Earth come from asteroids or comets?
False.
How do meteorites turn into?
Asteroids get caught in Earth's gravitational pull. Asteroids become meteroids when they enter Earth's atmosphere. Meteroids becomes meteors when they light up due to friction. Meteors become meteorites when they hit Earth's surface.
What was not a source of heat for early earth?
bombardmant by meteorites and asteroids.
Where meteorites came from?
Meteorites can from asteroids that landed on Earth's surface. They were originally chipped off larger planetary bodies by bolide impact.
Most meteorites collected on Earth are of the rocky primitive variety although most asteroids are of the carbon-rich variety?
Most meteorites are rocky and primitive.
What difference do asteroids have from other space components?
Asteroids are mass of earth or rock about the size ranging from 1 km to even 500 km. Meteorites are smaller than asteroids.
Do asteroids impact earth?
Yes, but fortunately, very rarely.
Are asteroids near earth?
Numerous asteroids are in constant motion around the earth, infinitely tracing their orbits. Occasionally some will collide or break down and fall as bits of meteor to Earth.
Why is a metoraite covered with fire?
MeteorItes typically orbit the sun like the Earth does. These orbits are at very high speeds. Occasionally, asteroids in the asteroid belt collide and cause them to head towards the inner solar system. Occasionally, these asteroids will enter Earth's gravitational field and eventually plummet towards the surface. Because these meteorites are traveling so quickly, and because Earth's atmosphere is oxygen-rich, the meteorite will ignite. Usually, this fire will normally consume the meteorite and it will "burn up" in the atmosphere. Only large meteorites would be able to make it all the way to the planet's surface.
