You cant reach outer planets

Well because the planets that we see keep move away from us and if we would fly with light speed we would fly a infinity distance because the space between expands.

The planets we're capable of detecting are only within our little piece of our galaxy, while loads of other galaxies are visible in all directions, so no, not for several trillion years, if ever, and even then only if the Big Rip hypothesis is the actual fate of the universe.  Also, nothing within space, including you, can travel at light speed, so you would have to cover billions of light years of space over more time than is left for stars to form and shine, let alone Earth's remaining lifetime, before space between you and Earth could expand too fast for you to return.

Quick mind-blowing science:
