Hello!

I have been thinking about space exploration and have come across an interesting problem. I haven't seen anyone mention this before, bu here it goes:

The biggest problem right now with traveling to other stars/galaxies is the light speed gap. We cannot even come close to light speed at this time. An alternative that is frequently proposed is using wormholes or shortcuts in space-time.

Ok, lets assume that we have the technology to create wormholes and we could use them to transport ships to other galaxies in an instant. Here is were I came across jet another problem. If we send a ship to another galaxy, lets not forget that other galaxies are moving away from is (the expanding universe) and may of them are doing so at great velocities in reference to us. Wouldn't this cause time dilation between the ship and home and as a result one would age more than the other or something to that regard?

Time is not constant, so this would make establishing a universal "empire" impossible it seems. Or what would you say?
