I was watching something recently in which the idea of light speed travel was explored, and it was thought that navigation would be essentially impossible, since it would require creating an indestructible field around the travelling object in order to move it safely through time space. The problem with this is that the indestructible bubble would then destroy all matter in its path on its way to its destination.

That doesn't sound like such a problem if you are in the bubble! Space is mostly empty anyway. The odds of colliding with anything meaningful would be pretty slim, no?
