If the earth people want to be space immigrants?

It can't be achieved with the current technology, but if human beings master higher technology, they may be able to sleep in this boring voyage and wake up after arriving at their destination, which can save a lot of fuel (of course, there are other schemes, but unfortunately generations have sacrificed their lives to achieve their goals).

As for the wormhole, man can't keep it open all the time, let alone shorten the voyage through it. At least in the foreseeable future, it is not feasible.

I hope it helps you.
