Is the Science of Your Universe Plausible?

In your book, these aliens can travel great distances between the stars. How much did you think about how that travel happens and how to make it plausible? That is a very good question. And the answer to that is, it was not a huge concern. But i'm pretty sure in the back of my mind, i justified it the way that a lot of, you know, really tropy, soft science fiction justifies it. Is the ringate or they have ehell, you know, they jump.
