If Q, and the other members of the Continuum can easily travel through time, then why in certain episodes, like in "Hide and q", does he express that humans could one day become at least as great as the Q, wouldnt he be able to find out? Since it has been shown that there are future humans, (Daniels, Braxton, timeships, etc), then wouldnt one possible future human beings become q-like or not, and be able to travel back in time, and be in the normal Star Trek-universe?
