we won't be able to answer this question for another 200 years!
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
unknown
the types of galaxies are barred, irreagular, spiral, and a shape like an hourglass.
There are other galaxies. Between the galaxies, there's lots of mainly empty space, with a very tenuous gas.
Sure. Why not!
It's what holds them together. (what's it like in your universe? ... since you're implying that yours is different.)
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.
spiral, elliptical, and irregular. The only differences are shape. Elliptical galaxies are shaped like an ellipse, spiral galaxies like a spiral or pinwheel, and irregular don't have a uniform shape
The Big Crunch: Like the opposite of the big bang, the universe collapses and goes into a point of singularity. The Big Chill: The universe will keep on expanding, until there is too few galaxies and stars, which will eventually die out too, so there will be nothing in the universe but a few black holes and decayed stars and galaxies
Go on 'actions' and press dance. There are a few different types like break dancing and robot.
No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.
There are actually four broad classifications : spiral, elliptical, lenticular and irregular. Spiral galaxies look, basically, like our Milky Way Galaxy, though there are some variations. Ellipticals can look elongated like a football, or almost spherical. Lenticulars are "lens shaped" galaxies. The irregular category covers just about everything else and include galaxies like our neighbors, the Large and Small Magellanic Clouds . (Classifications vary and there are some that have only three types.)
