If you could accelerate (in a reasonable time) to near the speed of light with respect our planet, let's say to 0.999999999999999999999999995 c, then you would reach the present (visible) limit of the universe and back to earth, in one day of your clock, but 28 billions of years on earth (non considering the universe expansion), if it will still exist!
