Imagination is what is needed here more than technical knowledge. Yes without gravity there would be no universe but one can't say gravity IS the fundamental. Because there would be no universe in the absence of the other three fundamental forces as well.
Just think about this, ours may not be the only universe, there may be lot of universes. Even our universe may be like our planet around the sun, it may be hanging on to something far greater than our universe. Its always good to imagine. If you can create it in your mind you can certainly recreate it on paper!
