In case,we made Worm Hole possible

In case,we made Worm Hole possible & travel to nearest Galaxy...from there we can see numbers of Galaxies, including ours

At that moment, weather it is possible to identify our Galaxy, Sun & our planet Earth???

Say you traveled instantly to the Andromeda galaxy. You'd see us as we *were*, about 2.3 million years ago. So, assuming you could spot the sun from Andromeda (no easy feat, as the sun is pretty puny), and assuming you could look in on the Earth from that distance... you'd see Earth as we looked 2.3 million years ago - the dawning of early man.

Yes, we will be able to identify our galaxy. With a good enough telescope, we would be able to identify our sun. We wouldn't be able to see the Earth though, it's too small to see from that distance.

it doesn't matter where you look from its the same distance from earth to moon or from moon to earth. same with the galaxies.

Yes it may be possible
