well....yes they could if we were that advanced. not yet but maybe in the future.
wrong its billions and trillions
No. Space holds everything in space. Galaxies are held in space by space.
Nothing is on space. There are two types of 'space' # Galactical Space- Space in Galaxies # Intergalactical Space- Space in between galaxies
Not Human explorers.
A billion other galaxies, scattered throughout space.
Not with present human technologies.
space ships. some people think that wormholes can lead to other galaxies
Astronomers, looking at deep space photographs of the Universe.
Yes. Looking at a deeps space image it is apparent that the universe is filled with Galaxies. It is estimated that there are about 200 billion galaxies in the observable universe.
The space in between galaxies is far larger than the galaxies themselves.
Just like other things in space, galaxies are not nailed or fixed to empty space - they can't help moving around. If some force (usually gravity) pulls something in outer space, then its velocity will change.
There are other galaxies. Between the galaxies, there's lots of mainly empty space, with a very tenuous gas.
