      Maybe one day!

      At the moment we have only just managed to leave Earth and travel to the Moon and Mars and those are very close to us compared to the size of a galaxy.

      The galaxy we live in (The Milky Way) is 52,000 light years across!! That means that light will take 52,000 years to get across, and light travels at the fastest speed possible! The nearest galaxy to us is called Andromeda and it is 2.5 million light years away!

      I think that the time it takes to travel to these places is the limiting thing here! If we could get a ship out of our solar system we would need thousands of generations of people who live, work, have children and die on one ship to travel to another galaxy.
