To explore my question more I will draw on the hypothetical series of Star Trek (and various other SC-Fi’s) where you can see out of the windows of Enterprise the stars flying past. If we were able to master warp speed, could we theoretically plot a course that could take us thousands of light years without bumping into anything? Although I assume master some sort of shield to block against small debris such as meteors would also be necessary?

If you can see stars that are billions of light years away, then I figure they must be huge up close, but on Sc-Fi programmes like Star Trek they still look the same size as they do from Earth. So can you please tell me how big are they really?
