Is travelling only in our galaxy our boundary. What about the universe.?

Okay.
1. Religion in a science category. I think you missed a signpost or something somewhere. I believe theological discussions belong there and not here. I'll look it up or pull it out from the "philosophy" section of my library.
*huff*
2. There isn't a boundary, as many people have said. To make it a little more clear, imagine that the universe were on the surface of a balloon. No matter where you went, or how far, you'd never hit a "boundary". It's difficult to visualize in 3 (or 4, or 11 for the string theorists) dimensions, but this is what the current theory is. Well, almost. The balloon analogy is only correct in pointing out the lack of boundaries. The curvature of the universe is actually open (like a saddle) rather than closed (like a sphere). Still no boundaries though.
Hope this helped.

As far as today's technology is concerned, travelling around the galaxy is a distant dream.
Travelling outside the galaxy doesn't pose to many problems beyond travelling around the galaxy. Just think of a few hundred years ago: people left Europe on their ships and set out into the great unknown, and they had to be completely self sufficient.
As for boundaries; the known universe extend about 15 billion light years, because that's as far as we can see (the universe being about 15 billion years old). It is entirely possible that the universe extends far beyond that, but it's entirely guesswork.

At the moment time seems to be the only boundary. You are stuck at now, unable to visit the future or the past.

Right now, it's the Boundary of your Imagination because we haven't gotten there. We don't know if it is or not.

I certainly hope that someone other than me has reported earnest77h for his abuse by using this science topic to post a sermon that simply wastes space, does not answer the question in the spirit it was asked, and is offensive to those of us that are endeavoring to deal with reality.

With out technology right now we are very limited to our planetary system except for extreme measures. After that for a few hundred years we will still be limited to our solar system unless there are some amazing discoveries.

I don't know that there is a "boundry" Per se...
There is the border or edge to which the universe
has expanded to date but this border keeps moving
outward as the universe expands..

No one knows the answer to that question.
