According to String Theory, by magnifying a point particle a vibrating string would constitute its root essence, and matter would be nothing but the harmonies generated by these strings, infinite of them, as the harmonies that can be played on a violin, resonating through an eleven dimensional hyperspace, or Nirvana, in which all forces of Nature would fit together. This Multiverse of universes featuring Big Bangs happening all the time, bubbles of universes fissioning and colliding and other being born by the Quantum space-time foam, with matter and antimatter being constantly created and destroyed allowing new universes to pop into existence and either expand or pop back. What if gravity was too strong or too weak in our universe? We wouldn't have been here to contemplate the question. The Sun would have never ignited had the nuclear and the electromagnetic forces been different enough. Our universe was fine tuned for our complex intelligence to emerge.
