Sorry if this was asked but I couldn't find a answer! I heard that when you travel at near the speed of light (0.999...c, wrt the earth or Sun maybe?) the universe would be seen blueshifted (even the CMB would be visible) and length contracted in front of you. However I also heard that we are traveling right now to 0.9999...c wrt a reference frame. Why don't I see stars or CMB blueshifted or length contracted in front of me? Many thanks!
