      I don’t think we will ever do it! In space we use a unit of measurement called ‘light-years’ which is how far light can travel in a year. We can’t travel at or past the speed of light without breaking physics! So unfortunately other galaxies are many light years away (light can travel very far!) so if we were to try it would take us at least thousands or millions of years to get there so we would be long gone by then to ever see them

      Unfortunately, not in our lifetime, but I believe that the future might have some technology that allows us to either overcome the speed of light, find some shortcuts in space or… allow us to “freeze” our bodies in time so that we can somehow survive going that far!

    We might use what is called a “generations ship” to do it. Where the ship sets off and the people on that ship live out their lives as normal. Then their kids do the same and so on and so forth. Many generations later that ship can arrive at its destination in a new galaxy with the decedents of the people who originally set off from earth. Since a ship that big wouldn’t travel very fast it could take over a million years to reach Andromeda which is the closest galaxy to ours.

    We could just be lazy. If we wait long enough (around 5 billion years) there’s a fair chance Andromeda will come to us and save us the trouble of going to it.
